I personally did not find this product worked. Maybe you need to consistently use it for months at a time. Not worth it for the effectiveness considering the price you pay.

After chemically straightening, and a few rounds of highlights, my hair was completely fried. A friend/hairstylist recommended Redken Extreme Anti-Snap to me, as my hair was breaking off all over the place and was a complete mess. Over several months of use, my hair stopped breaking off and became strong and healthy again. I highly recommend this product.

I started using this several years ago when my hair was completely fried from the chlorine in pools (I was a swimmer). It USED to work quite well back then, but since repurchasing a few months ago, I havent really noticed a difference in my hair. Granted, my hair is no longer damaged so maybe it works best on hair that is severely dry. Smells great but probably won't repurchase again. Would recommend to those with super damaged hair, though.

USED THIS WHEN I WAS GETTING MY HAIR DYED AT THE SALON, AND AFTER, HAS HELPED MAINTAIN THE STRENGTH OF MY HAIR, REDUCING BREAKAGE.

After my over processed hair was snapping off from bleaching. I was freaking out and trying not to style my hair ever again in fear!
I bought this Redken Extreme Anti-Snap leave in treatment and styled it as usual.
It has helped me so much and I can rest assured my hair won't be snapping off anymore. Love this product!!! Highly recommend it. Smells great too!
