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.

I've used this product for years and this new formula is awful. The smell is terrible and the new change doesn't have the same effect with taming frizz please change it back!

No, I do not recommend this product.

Fresh not Frizzy

This shampoo from Matrix really helped my frizzy hair. I really noticed a positive change with dandruff too. The shampoo lathers great with just a small amount, and smells wonderful too. It rinses easily and I am able to go a couple days without washing it again because it leaves the hair feeling fresh and less products is needed for frizz.

This shampoo lathers extremely well and doesn't dry out my scalp at all. It smells amazing (this whole line does) and I'm fairly confident this bottle is going to last me a while. I don't know if it has any true effect on calming any frizz, however.

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!

Best shampoo ever!

14 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!

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!

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!

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.

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.

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.

I’ve used this shampoo and conditioner for over 10 years and loved the clean scent it used to have. Now it smells tropical like every other shampoo and conditioner and it’s a terrible smell. I bought the product from Ulta and returned it. You lost a long time customer! So disappointed

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.

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!

The Mega Sleek Smoothing Shampoo lathers nicely and smells great.

We haven’t had many humid days, so I’m not sure about that, but my hair looks smoother after using it.
