It's a 10 Haircare Miracle Leave-In Plus Keratin, 2 Fl. oz.

I really like this product. I've been using it for years. It works to tame some of the frizz that's more prominent with my hair since I've gotten older and have been dying it.It's not too heavy. My thicker hair doesn't feel greasy with it on. Not sure how it would work with thin hair, but they have a smaller bottle that you can try if you don't want to invest in the larger bottle just to see if it works for you.

After having highlights in my baby fine hair, it became very dry and brittle and looked awful. I searched for a product to help me, and after reading reviews for many products, I decided to buy "It's a 10". It has saved my hair, which looks and feels so much better now. I use it on my hair while it's still wet after shampooing, which makes it easier to brush and comb through without breakage. For protection, I use it again before I use my flat iron. I am very happy with "It's a 10" and I'd recommend it to others, especially if they have fine, fly-away hair.

My hairdresser recommended this to me over 5 years ago. I absolutely love it since it's not heavy, very lightweight and tames my frizz easily. The price is much better than the salon or supermarket. I bought several sizes so i have one for travel. I like all of their products. Highly recommend!

I’m a black woman and I’ve been using this on my 3b/c hair! My hair was so dry and brittle even after using moisturizers and oils. It seemed like nothing would moisturize my hair! I was getting frustrated until my hair stylist recommended this product. Now my hair is always so soft and my curls stay poppin! When I wear my hair in a bun, I spray this instead of water and omg it’s great! Highly recommend!

It’s a great leave in for your hair without being heavy. I have very fine thin hair & this helps keep my hair strong, lot less breakage and so shiny! I have tried so many other keratin & strengthening leave ins & I always come back to this one…

I think it worked well. Bottle is pretty small. Didnt make such a significant difference that I will continue to purchase.

This product is great for minimizing the appearance of damaged ends and tames frizz. I was over processed by a hair colorist and have been gradually getting the damaged hair trimmed off without a drastic cut. This has been the best of all the products I have tried.

First - it is definitely 10oz. That a plus! Also you can just spray and leave it in. Makes hair softer and stronger. Highly recommend!!
