If you like silicone based products…

[This review was collected as part of a promotion.] I gave this 2 stars for the simple fact that it does indeed do what it states on the bottle; “intense condition” and offer heat protection. My hair was nice and soft and easy to comb through - as expected with DIMETHICONE or silicone based products. However, I tend to avoid silicone based or anything that has dimethicone in it, and it’s the second ingredient after water. Meaning, this product is mostly silicone. I do not like how silicone based products make my hair feel overtime and that is why I avoid them. This product did have a nice scent and made my hair feel and smell nice but I will not be using it again. The trial size was a perfect size as I got a handful of uses out of it.

[This review was collected as part of a promotion.] The Redken Ácidic Perfecting Leave in Treatment is a hair mast that you use before your shampoo and conditioner is a leave in treatment that help smooth the hair. My hair felt smoother and soft. I definitely do not recommend if you have long hair like me it require to use a lot of product, since the product is pricy bur if you can afford it is worth it.

is it worth it

[This review was collected as part of a promotion.] Its absolutely worth it my hair feels absolutely amazing and it was the perfect amount needed for my hair. I let the treatment sit in my hair for around ten minutes and my hair felt so soft and curly. It doesnt really have much of a smell and the packaging was great and small. The only problem is if you have longer or much thicker hair you probably need more of the product. But other than that my hair feels alot more healthy and I will be using this again. My hair is natural never been colored so I dont know how it will work on colored hair, but I 100% recommend this Third pic is before

[This review was collected as part of a promotion.] I liked this leave-in treatment because it helped hydrate my hair without weighing my hair down. My hair is as soft as ever and repaired. This treatment felt like it brought my dull hair back to life. I definitely recommend this product because it gives you salon quality hair without going to the salon! :)

I use this leave-in treatment every time I wash my hair. I put it on my damp hair and then blow dry. I love that is doubles as a heat protectant! This product makes my hair feel so smooth and look so shiny!

O M G!!!!!!! This

O M G!!!!!!! This stuff is beyond words, I have extremely dry brittle hair from bleaching and have been desperately trying to find a product that would help. After trying a few things that didn't work I went to ulta and asked about a few items. The lady working recommended this set and because she personally uses it I thought why not!!! This did not disappoint, in fact after one use my hair is sooooooo soft and doesn't feel crunchy!!! It is expensive (but not as much as the pureology) and so worth it if your hair is as bad as mine. So happy this was recommended to me!!
