New formula awful

7 days ago
The new formula is horrible. Hair feels dry and brittle and it leaves a lotion like residue on your scalp that you can scrape off with your fingernails. It gross and disappointing they don’t change the bottle enough to note the formula change. I’ve been using this brand for 10 or more years. Very disappointing

You make a completely fair point that such a drastic formula change should have been clearly noted on the bottle, and we are escalating your feedback on scalp buildup and packaging transparency directly to our team.

Bad, Bad, Bad

Ugh. They discontinued this product, created a new one, and called it by the same name. I’ve been loyal for 28 years. I gave the new version a solid try. It’s not good. Bummed I have to move on. If you ever bring back the original scent (that we all know and love), please let me know.

No, I do not recommend this product.

Thank you so much for an incredible 28 years of loyalty to Matrix, and we are deeply sorry that giving the new version a solid try left you disappointed and moving on. You are completely right: changing the formula and classic scent so drastically while keeping the same name feels misleading to our most dedicated customers. While the original formula has been discontinued, we are passing your feedback directly to brand leadership. We refuse to let your loyalty end on a bad note, so please contact our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST).

Sad about the change

23 days ago
Extremely disappointed in the new formula after using this and food for soft along with the serum, I find myself searching on Google for known alternatives now. This definitely does not work for smoothing the way it used to. Unlike other reviews the smell did not bother me but otherwise it’s a total let down and I won’t be buying anymore. It’s unfortunate I just bought two large bottles for as expensive as they are!

No, I do not recommend this product.

Thank you for sharing your feedback with us, and we are so truly sorry to hear that the updated Mega Sleek formula has let you down, especially after pairing it with Food For Soft and investing in two expensive, large bottles. It is incredibly frustrating to find yourself searching Google for alternatives to a staple routine you relied on for smoothing. While you didn't mind the scent, we hear you loud and clear on the loss of smoothing performance. We refuse to let your investment in two large bottles go to waste, so please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can issue a full refund voucher for both bottles and help make this right.

Very upset about product change for mega sleek

I am so mad 😡 I’ve been using matrix mega sleek for YEARS and I go to buy my favorite hair care and you have changed the formula!?! The smell is atrocious! Shame on you for changing. Looks like I’ll be finding a new brand! You are going to lose money on this. Absolutely ridiculous!

Go back to original formula

30 days ago
The new formula sleek shampoo/Conditioner is horrendous, the smell is so overwhelming it causes nausea. The added dyes do more harm then good, removing the shea butter, has wrecked this amazing shampoo conditioner combo, I have recommended this line to my clients for 10 years, I can no longer do that, as they have all returned it to me. This is more then disappointing. Hair is now frizzy, hard to brush. Where it did not used to be. How to fix this issue, Go back to the amazing original formula. It was wonderful, smooth, made long hair look amazing.

No, I do not recommend this product.

We are deeply sorry that the renovated Mega Sleek formula has compromised your work and resulted in client returns after ten years of trusted recommendations. You diagnosed the exact formulation issues: removing the rich Shea Butter in favor of a lighter Jojoba Oil base stripped away the essential slip needed for detangling and frizz control, while the added synthetic dyes and overpowering caramel-pistachio fragrance have proven overwhelming in the salon chair. Your professional reputation means everything to us, and we are escalating your direct feedback straight to our professional salon division.

[This review was collected as part of a promotion.] I love the matrix smoothing shampoo. I use it with the matrix, smoothing conditioner, and the matrix hair mask. It smells absolutely amazing and not only is it lightweight but it doesn’t leave your hair greasy or with flakes and residue. It leaves my hair feeling so soft and shiny and no tangles. It even tamed my ridiculous frizz that was so bad. I wish I had a picture to show for that, but I do not unfortunately but just know this product does work and it does not dry your hair out!

The new fragrance is awful! I now have an entire liter of shampoo and I hate the way it smells. It needs to have huge letters on the bottle telling customers the scent is completely different, so we don’t make the mistake of purchasing a product that is so stinky . I am so disappointed.

We are deeply sorry for the disappointment and frustration you experienced with the updated Mega Sleek shampoo, especially after purchasing an entire liter bottle. You make an entirely fair and valid point: when a signature fragrance undergoes such a drastic shift—from our subtle classic salon scent to a warm, sweet caramel-pistachio profile—it should be clearly and boldly labeled on the bottle so loyal customers aren't caught off guard. Scent is an intensely personal part of your daily routine, and no one should be stuck with a full liter of product they dislike. We are passing your direct feedback about packaging transparency and the fragrance overhaul to our brand marketing leadership. We refuse to leave you stuck with a liter bottle that you hate, so please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST).

Loyalty down the drain

a month ago
I’ve been using the mega sleek shampoo and conditioner combo for probably close to 20 years at this point and was so confused with my latest repurchase. I kept looking at the bottles to make sure I wasn’t losing my mind. Both products are so wildly different than before. The color, texture, viscosity, scent, all different. I’m not sure who decided that this was even remotely the same product as before. My hair feels heavily, but also dry and brittle. I’m so upset that I bought my usual large bottles of this, only to be stuck with this grossly disappointing product. Not looking forward to have to find a replacement product.

No, I do not recommend this product.

We are deeply sorry for the confusion and disappointment you experienced with your latest purchase after 20 years of loyal use. We completely understand why you were checking the bottles—when color, scent, viscosity, and performance all change so drastically, it truly feels like a different product. Swapping the original Shea Butter for Jojoba Oil was meant to make the line 100% vegan, but we recognize it can leave hair coated and heavy yet dry and brittle. We refuse to leave you stuck with large bottles that don't work, so please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST).

We hear your anger and frustration loud and clear, and we are so deeply sorry for how much this formula change has let you down. Hearing that you feel this renovation was driven by cost-cutting rather than customer care is hard to read, but we completely understand why it feels that way when a product that worked perfectly for you is suddenly altered. Our intention with this renovation was to transition the line to a 100% vegan formula, swapping our original Shea Butter for a Jojoba Oil blend and modernizing the scent. However, we recognize that removing what made the original so special has broken our loyal customers' trust and delivered results far below what you expect from a professional salon brand. While the original formula has been discontinued, we are passing your direct feedback—and your clear demand to bring it back—straight to our executive brand leadership. We do not want you to feel out of pocket, so please contact our Matrix Consumer Care team at 1-888-777-6396.

New formula fails to match the old one.

a month ago
Why? Why? Matrix why did you discontinue such an amazing product and replace it with such a subpar product? To add to injury, you are duping your loyal users by keeping the packaging and branding same and selling a completely different product. I have used this shampoo for over 14 years and the new formula is nowhere close to the old one. It's a completely new product with obnoxious overwhelming scent and leaves my hair very frizzy, dull and heavy. Anyone here praising the new formula has been given a free product ane asked for review. They are not the long term users of this shampoo. So ignore those reviews. Washing your hair few times with a free product you received and going back to your fav shampoo doesn't reflect true reviews. Matrix listen to your loyal costumers and bring back the old formula. Sell your new formula as a different line. -A very disappointed customer

I used this shampoo/conditioner for years, it was the only one I liked. After the formula changed not too long ago, it’s horrible. It gave me a reaction on my scalp, and the inside of my ears became red and pealed. No matter how much I would wash my hair it left a coat on it.

Thank you so much for your 20 years of loyalty to Matrix, and we are deeply sorry for the headache-inducing scent and tangled, unmanageable results you are experiencing with the new formula. Relying on a formula for two decades—especially for the comfort and balance of your scalp—is a huge deal, and having to start over and find something else is incredibly frustrating. When we renovated Mega Sleek to be 100% vegan, replacing the original Shea Butter base with Jojoba Oil and introducing a new caramel-pistachio fragrance, we recognize that the soothing slip and subtle aroma you depended on were lost, leaving your hair tangled and your scalp unhappy.

Go woke, go broke. New vegan formula is horrible.

a month ago
This would be a great time for one of those “You asked, we listened.” announcements. Please go back to the old formula! Whatever woke marketing Matrix was aiming for by going to this new formula is probably being negated by all of the customers they are losing just because Matrix wants to be vegan. Cater to one small subgroup, lose the majority of your customers. Great idea. If Matrix wanted a vegan product, they should just make a vegan line. Leave the staple products alone!

No, I do not recommend this product.

I have been using the matrix sleek look shampoo and conditioner since the late 90s. That alone tells you how much I liked the product. Until now. This new formula is junk and the scent is so strong that I can’t stand to wash my hair with it. I will never understand why companies have to mess with products that are already successful. Matrix just lost a customer. A lot of them probably.

Thank you for taking the time to share your feedback with us, and we are so sorry to hear that the updated Mega Sleek formula is weighing your hair down and leaving it feeling heavy and oily. When we renovated the line to be 100% vegan, we replaced the original Shea Butter base with a Jojoba Oil blend and introduced a new, warm fragrance profile. However, we recognize that on many hair types, this new formula can sit heavily on the hair shaft instead of absorbing, leaving strands greasy rather than clean and smooth, while the new scent can be overpowering. We want to make this right for you, so please reach out directly to our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST). Our team will gladly assist you with a full refund voucher and help guide you to a lighter, weightless alternative from our collections—such as our Food For Soft line—that cleanses cleanly without leaving behind any oily residue or heavy scent.

Can’t stand the smell!

a month ago
I love this product (with the shea butter) and have used it religiously for 15 years. It was one of the few shampoos out there with salon quality results without the perfume salon smell. Unfortunately the new formula with oleic acid and jojoba oil is very fragrant. The odour is not foul but it is incredibly fragrant and I cannot tolerate my hair smelling like this all day nor can I get away with using this shampoo working as a physician in a scent-free hospital setting. Please please consider keeping a unscented shampoo option for those of us who don’t want the ‘salon smell’😢

No, I do not recommend this product.

Why change the formula!!

I’ve been using this shampoo and conditioner for years and my grandma has for even longer. She has severe allergies to scented products so she couldn’t use the new one even if she wanted to :( unfortunately, it’s not just the scent. The conditioner leaves an unwanted residue on the hair.

Thank you so much for reaching out and sharing your family's story with us. Hearing that you and your grandmother have trusted Matrix for generations makes this especially heartbreaking to read, and we are deeply sorry that our new formula has let you both down. When someone has severe fragrance sensitivities or allergies, having a go-to, low-scent staple suddenly replaced with a strong gourmand perfume makes the product completely unusable and unsafe for their routine. In addition to the updated fragrance, our shift to a 100% vegan formula replaced rich Shea Butter with a lighter Jojoba Oil blend; however, we recognize that on many hair types, this new blend can leave behind an unwanted, waxy or heavy residue rather than rinsing away clean and silky. We completely understand how disappointing this is for both you and your grandmother.

Awful new scent

2 months ago
I am so disappointed in the formula change, specifically regarding the scent. I thought my daughter wasn't washing her hair properly, but its the new formula that makes her hair stink. So bummed because it used to smell so good before the formula change.

No, I do not recommend this product.

Thank you for reaching out to share your feedback with us, and we are so truly sorry for the disappointment and frustration this formula change has caused in your household. It is especially disheartening to hear that the updated fragrance was so off-putting that you initially thought your daughter wasn’t washing her hair properly. As part of our transition to a 100% vegan formula, we modernized the fragrance to a warm Salted Caramel and Sicilian Pistachio profile. However, we recognize that this sweet, gourmand aroma is a drastic departure from the clean, subtle salon scent long-time users loved, and when it interacts with wet hair or lingers throughout the day, it can be overwhelming and unpleasant. We completely understand your bummed reaction and want to take care of you and your daughter. Please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can process a full refund voucher for your purchase. Our team would also be happy to guide you toward a fresh, clean-scented alternative from our collections that you both will love.

Thank you so much for your incredible 25 years of loyalty to Matrix, and we hear your anger and frustration loud and clear. Losing a staple product you relied on for a quarter of a century is a massive disappointment, and hearing that our new formula stinks, performs terribly on your hair, and forced you to find another brand is truly heartbreaking. Our transition to a 100% vegan formula replaced our original Shea Butter base with Jojoba Oil and introduced a new gourmand fragrance profile. While corporate formula renovations are complex, you are entirely right to demand that your voice as a 25-year advocate be heard. We are escalating your direct feedback—and your clear demand to bring the original formula back—directly to our executive brand leadership. We do not want you to feel that your money was wasted after decades of supporting us. Please contact our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST). We are so sorry to have lost your trust after all these years and are committed to making this right for you.

It’s a NO from me

2 months ago
I’ve used this shampoo since the early 2000’s, I knew the day would come when it got discontinued bc it was too good to be true, but I’m still so upset. I thought my bottle was spoiled, the scent is awful and much too strong. The main benefit of the old formula was that it’s one of the only shampoos with barely any scent, this “updated” formula is supposedly cleaner and healthier yet contains artificial scent. The old formula was smoothing without being heavy and never over dried, I cannot say either of those things now. Please bring back the original!! I’m devastated I’ll have to switch to another brand. By the way “updating” a product by changing almost all of it is very misleading and disappointing.

No, I do not recommend this product.

Thank you for being an incredibly loyal user of Matrix since the early 2000s, and we are so truly sorry for the devastation and disappointment this reformulation has caused you. Relying on a shampoo for over two decades is a rare level of trust, and we completely understand why you feel upset and misled by an "update" that changed almost everything you loved about the product. You bring up a very important point regarding the fragrance: one of the key reasons so many long-time users loved the original formula was its clean, subtle, and low-key scent profile. Replacing that with a heavy, artificial gourmand fragrance—while marketing the line as cleaner and modernized—feels contradictory and overwhelming. Furthermore, losing the signature balance of lightweight smoothing without stripping or weighing down hair is a huge loss. While the original formula has been officially discontinued, we hear your plea loud and clear and are passing your comments on fragrance transparency and performance directly to our executive brand leadership. We want to make sure you are supported, so please reach out to our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST).

My New Favorite Shampoo

2 months ago
[This review was collected as part of a promotion.] With curly hair, I often struggle to find the balance between shampoos that properly get rid of product build up, but don’t strip the material and needs oils from my hair. This shampoo has proven that that balance can be done! This shampoo is great at lathering up while making my cruel feel soft once rinsed off. It’s my new favorite shampoo!

Terrible New Formula!

2 months ago
Whaaa! (That’s me crying) So sad you changed my favorite shampoo and conditioner ever! My hair was a hot mess after using this new formula of Mega Sleek. Dull, flat, wouldn’t hold a curl…and smells terrible. Boo! I have used these products for 10 years and now I’m scrambling to find something else. What were you thinking changing perfection? Please bring back your old formula!

No, I do not recommend this product.

We hear you, and we are crying right along with you! Hearing that a product you considered absolute perfection for ten years left your hair a "hot mess"—dull, flat, unable to hold a curl, and with a scent you dislike—is heartbreaking for us. When we renovated Mega Sleek to be 100% vegan, we replaced the original Shea Butter with Jojoba Oil and updated the fragrance, but we recognize that for long-time fans like you, this change completely ruined the magic. While the original formula has been officially discontinued, we hear your plea loud and clear and are passing your direct feedback about the loss of hold, shine, and scent directly to our product development team. We don't want you scrambling without support! Please reach out to our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) for further assistance.

New formula is trash!

2 months ago
Why are you selling a completely new formula in original bottle? It's a completely new product: color, smell and it's effectiveness. It completely weighs down my hair and makes it look dull and flat. Original formula left it shiny and smooth. Have been using the original for about 15 years. BRING BACK THE ORIGINAL FORMULA. SELL YOUR NEW FORMULA AS A NEW PRODUCT!

Thank you for being a 15-year loyal user of Matrix, and we hear your anger and frustration loud and clear. You raise a completely valid point: when a product undergoes a complete transformation in color, scent, and performance, continuing to sell it in similar packaging feels misleading and disappointing to long-time customers who rely on the original performance. When we updated the Mega Sleek line to be 100% vegan, we replaced the original Shea Butter base with Jojoba Oil and updated the fragrance. However, we recognize that this shift resulted in a completely different experience—leaving hair dull, flat, and weighed down instead of glossy and smooth. We understand why you feel this should have been launched as an entirely separate product rather than replacing the formula you trusted for fifteen years. While the original formula has been discontinued, we are passing your feedback directly to our brand and product management leadership to highlight the serious impact this repackaging and reformulation has had on our most loyal customers. We want to take care of you, so please contact our Matrix Consumer Care team at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST) so we can make this right.

Please bring back the old formula

2 months ago
The new formula is awful!! The scent is so over powering, and it’s not a good smell either. My hair feels so dry and my scalp has been so itchy since this switch in ingredients. I am so sad, I’ve been using this product for many years. Please, bring back the old formula. It was so much better than whatever this is.

No, I do not recommend this product.

[This review was collected as part of a promotion.] This shampoo leaves my hair feeling soft, smooth, and shiny after every wash. It provides great hydration without weighing my hair down, and the fresh scent is a nice bonus. My hair feels healthier, more manageable, and easier to style. Overall, it’s a great option if you’re looking for a nourishing everyday shampoo.

I liked the old formula better… old formula 5 stars… this one 3. I have used the old formula for 10 plus years and I might have to find a new product.

No, I do not recommend this product.

We completely understand why you are considering looking for a new product after relying on the original formula for a decade.

Matrix Mega Sleek Made Me Love My Hair Again

2 months ago
[This review was collected as part of a promotion.] Matrix Mega Sleek Made Me Love My Hair Again I received the Matrix Mega Sleek Smoothie Supreme Mask, Smoothing Conditioner, and Smoothing Shampoo complimentary from Influenster, and I am genuinely blown away by how well they worked for my hair. I have a mix of 2C, 3A, 3B, and 3C curls that are high‑porosity, often dry, and now more than 50 percent white. The new coarse texture has made my curls feel unruly and harder to manage, and it’s been tough to feel like myself as the gray has come in. These products changed that for me. My curls were soft, shiny, and bouncy, and they popped in a way I haven’t seen in a long time. I was worried the line might leave buildup, but it didn’t at all. Everything rinsed clean, and my hair felt hydrated instead of coated. On the rare days I wear my hair straight, this line impressed me even more. Nothing has kept my frizz under control the way Mega Sleek has. The smoothness lasted, the shine stayed, and my hair didn’t puff out by midday. I loved these products so much that I immediately purchased the Mega Sleek Anti‑Frizz Topcoat Serum. It was the perfect finishing touch. Matrix Mega Sleek didn’t just make my hair look better. It made me feel like me again. Highly recommend for anyone with curls, high porosity, or coarse grays who wants softness, shine, and real frizz control.

Disappointed in the updated formula

2 months ago
I'm not happy with the updated version of the mega sleek product. It doesn't leave my hair as soft as the other formula. And it's more stiff when I brush it after washing it.

No, I do not recommend this product.

Thank you for sharing your feedback with us, and we are so sorry to hear that the updated Mega Sleek formula is not delivering the soft, touchable results you loved. The shift from our original Shea Butter base to a lighter Jojoba Oil formula was designed to offer weightless smoothing, but we recognize that on many hair types, it can leave hair feeling less hydrated and noticeably stiffer or harder to brush after washing. We want to make sure you are taken care of, so please reach out to our Matrix Consumer Care team directly at 1-888-777-6396 (Monday–Friday, 9:00 AM – 5:30 PM EST). Our team will gladly assist you with a refund voucher and can recommend a deeply hydrating alternative—such as our Food For Soft line—to help restore that effortless softness and slip back to your brushing routine.
