HELP - Smoothing color-treated hair
12 years ago
I love the smoothing effect of this product. HOWEVER..... it removes the color (from hair dye) after washing my hair a few times. I wish that the company created a product which smoothed hair for those of us who colored our hair.

A favorite RUINED by STRONG PERFUME!
2 days ago
The new scent is STRONG . If you like the scent you may enjoy the product but save yourself complaints and ask before using this on a client. I for one wont put that scent on myself again or use it on a client without them smelling it first. I have been using Matrix Mega Sleek for over ten years and the lightly scented original was not an issue for clients who favor products that are unscented or at least subtle. Now the perfume is a deal breaker. I have had good results from Matrix Mega Sleek for over ten years but now I will need to find a replacement. You have ruined one of my favorite products!

Awful

Having been using this shampoo for years! I hate the new formula-leaves my hair feeling sticky and difficult to comb through . The smell is also displeasing. Reminds me of a big box store type product not one of salon quality Please switch it back !
No, I do not recommend this product.

Best shampoo ever!
5 days ago
The best shampoo I have ever used!
I had been struggling lately with my dry scalp it would get very flaky and I have tried many things to fix it but this shampoo is a game changer it hydrates my hair very well which has prevented my scalp from flaking the shampoo also smells so good it smells very fresh and clean but also sweet which I really enjoy. I would definitely recommend overall but especially if you are struggling with a dry scalp as I have noticed a tremendous difference.

Love the line!
6 days ago
I really like this shampoo but for the amount of product I put in my hair in the summer I feel like you definitely need to double wash and use a clarifying shampoo first if you have wavy or curly hair! Other than that I love the scent and consistency and I think the line all together has kept my hair so smooth!

Great shampoo!
7 days ago
I was pretty pumped to try this matrix shampoo.Despite the horrible, bright orange color of the bottle (and really the rest of the bottle design is horrible too--so many fonts and colors and directions). Plus the bottles are printed different directions. They get half a point for having the conditioner be the bottle that opens upside down so it doesn't pour out when you flip the lid, because it's a thicker product, I'll give them that, but since the design of the bottle is not really the most important thing here, I do love the shampoo. It smells absolutely glorious. It's a smooth clean shampoo despite not having any sulfates. it rinses so easily and quickly, and a little goes a long way so this bottle will last a really long time. Plus there is an entire system with a conditioner and masque so you can make sure all your products are working together!

Very hydrating
8 days ago
I absolutely love the Mega Sleek line! I’ve tried so many different products that didn’t help tame my frizz, especially in this South Carolina Lowcountry heat and humidity. It’s hydrating and conditioning by itself. Whenever I color my hair myself, I’ll shampoo 3 times to make sure the color has rinsed out and then let air dry for a few hours so my hair can really absorb whatever product I use next. Just the shampoo really conditions, detangles and hydrates while it cleanses the oil and product buildup.

Leaves hair smooth, shiny, soft, and fresh with light volume and no heavy feeling
9 days ago
The shampoo leaves my hair smooth shiny and soft without drying it out. It also helps reduce frizz and adds light volume. The bottle easy to use and convenient it in shower. The shampoo has a smooth texture. A small amount goes a long way so the product feels worth the price.

Clean feeling scalp does not leave hair feeling dry, but ready for the conditioner to follow after using the shampoo. The sense is clean and does not last for a long time which I appreciate.

Lightweight Frizzy Hair Reducer

It's a good product if you want something that is lightweight that helps to reduce frizzy hair. However, I was expecting my hair to be more shiny but I didn't really see that with this shampoo. I feel like other products do a better job when it comes to adding shine.

These mega sleek products are great! They smell so good and work well together, making my hair feel so soft and sleek, and giving me frizz-free curls. I was able to wear my natural curls and still feel confident, so I’m definitely going to be using them from now onward. I’m glad to have finally found something that works for me!

I really love this line of hair products so much and the shampoo really delivers!! I have wavy hair that can sometimes feel tangled and dry, even in the shower. Unlike many other shampoos, this one actually seemed to hydrated my entire head of hair like a conditioner! Hair was smooth and shiny after. Im now a convert to Matrix but will need to buy a bigger bottle next time as this size wont last long enough.

Smells great and left my son’s hair (video) feeling smooth and moisturized. When he woke up in the morning his hair looked good, wasn’t all crazy like usual. Rinses well like the average shampoo does. Doesn’t dry out the scalp and did I mention it smells amazing?! Use it with the conditioner +/- the hair mask for a better result.

Great Shampoo for Tangle Prone Hair

I absolutely love this line from Matrix! My hair has never felt so soft and non tangled before when waking up in the morning. The scent on top of it is really good and not too strong. It does a great job at cleaning but the only thing I didn’t like was how flimsy the bottle was. I dropped it once and the top flew off so now I can’t close it. Besides that, I love the product inside!

Lathers great, smoother hair

The Mega Sleek Smoothing Shampoo lathers nicely and smells great. My hair feels so clean after using it, and after using the conditioner and mask that are a part of this system, it feels softer and silkier. We haven’t had many humid days, so I’m not sure about that, but my hair looks smoother after using it.

We are very sorry to hear about your experience. It is incredibly frustrating to invest in professional products only to have them leave your hair feeling dry and sticky.
We recommend checking the return policy of your retailer, as many authorized sellers offer satisfaction guarantees even for opened products. Additionally, try a clarifying wash to help remove the sticky residue. Your feedback is valuable to us, and we apologize that these products did not meet your expectations.

So glad I found this shampoo. With the conditioner and mask as well, it’s even more effective, but even on its own, I love it. It can be hard to find moisturizing/smoothing shampoo that doesn’t weigh my hair down, and I don’t have that problem with this. Smells great, lathers nicely, and rinses easily.

I used Matrix sleek and smooth down shampoo and conditioner for over 10 years and I loved it until you all decided to change the formula for the shampoo and conditioner. Recently I bought both shampoo and conditioner at Ulta and noticed that it was a different color but two it left my hair very stringy and dirty. I'm very sad and upset because now I have to find another shampoo and conditioner. I will never use these two products again. You just lost a customer.
