Great mask! I use less then the recommended and
Scent: Keratin
Okay, long review here from a busy working mom. Here it goes! I have color treated hair that comes half way down my back, not really thick or thin, and wavy not curly or straight. I bought the Keratin Shampoo and Conditioner as well as the mask after seeing several hair enthusiasts telling someone that the way to help get rid of their unruly frizzy hair with our Florida humidity was a Keratin treatment. I don’t wish to spend the money on a treatment so I decided to try this set after reading product reviews. I am not disappointed! The first use and I could feel the difference of the Shampoo compared to others. It lathered nicely and left my hair feeling clean but I could tell it was leaving nourishment behind not making my hair feeling rough. Next came the conditioner. Now, since I fully intended on doing the mask right after anyways, I didn’t do my normal ritual of putting the conditioner on and leaving it for a few minutes before a cold water rinse. I simply put it on and almost immediately rinsed it out with the same temperature water I was showering in. My hair felt so soft and smooth instantly, better then other conditioners I have used and left on for lengths of time to really try to condition my hair. Just these two products are amazing but… then came the mask. I towel dried my hair as recommended and then applied the mask to my hair. I didn’t follow the guidelines of how much they said I should put in because it honestly seemed like overkill once I applied some in. If I had to guess it was probably 3/4 of an ounce to maybe and ounce when the mask directions suggests 2-4oz. I left it on for the 10 minutes without applying any heat and then cold water rinsed it. I don’t blow dry my hair so I let it dry naturally and could tell my hair was less flighty and softer. The next morning I straightened my hair and OMG! It was so soft, smooth and beautiful. People actually noticed the difference in my hair but couldn’t figure out what it was even though I proudly told them. I went all day at work (retail) without brushing my hair once. It didn’t tangle like it usually does and looked great even after going in and out of the building. I was so excited to do the next treatment (I didn’t it tonight and the decided to post this) and see what the results are (won’t really know until tomorrow) but I already know they are undoubtedly going to be amazing. How I’m going forward with my treatments, shampoos and conditioner every shower. Mask 3 times week one, 2 times week two and then hopefully once a week after that depending on if I feels like that’s enough. I was so happy with these results I had to share in case it helps someone else! Sorry again for the long review but someone needed to here it.

Excellent product
Scent: Keratin
I have had frizzy hair all my life and once I went gray it became very much like my wire terrier’s hair! I have had keratin hair treatments but they are expensive. I use this keratin mask once or twice a week after shampoo and it works exceptionally well. I love the smooth silky texture of my hair. Well worth the price and it saves me money.
