    Great product, but doesn't work for everyone

    I bought this for both myself and the hubby who has long hair, but his gets frizzy on the ends. While it works beautifully for me, it really didn't make much of a diff for his hair. This is after 4 or 5 days in a row he used it. Maybe worth a try though. Can't hurt. But I would start out with the small size. It doesn't take much, so it is plenty enough to find out if you want to buy more

    Not bad, but not good.

    I don't think this is a bad product, but I don't think it's a great one either. It tends to be a bit sticky while I'm blow-drying my hair. I thought it was a conditioning mask, but I feel like it's more of a smoothing styling aid, although to keep the immediate smooth results you still have to use a styling product too. I'm in Texas and we have very high humidity so it's not easy creating a lasting style and keeping frizz at bay. Perhaps I would have liked this better if I was in another climate, but I can't really tell what its purpose is.

  • k18 for hair is wonderful!

    Great product for chemically treated hair. This product leaves my hair so soft and healthy. I appreciate the fast shipping and well packaged. I highly recommend this product. Thank you very much! Oh, this is my second order and will continue to order again.

  • Best hair product ever

    I can’t get a brush or comb through my hair without this leave in hair mask! I have tried so many different products & always end up giving them away! My hair is very long & tangles easily. A little goes a long way. This is a good price! Less expensive than the company that makes it!

  • Amazing!

    Best product I have used in a long time, and it gets better after you put it in after one wash. Also, my naturally-curly hair doesn’t frizz anymore — it actually goes into beach waves now!
