I have very dry hair, because I frequently have it colored,and I also blow dry and flat iron daily. The ends are extra-dry and tend to be frizzy. I purchased this in an effort to deep condition it and moisturize it. I first shampooed my hair and then applied it, paying extra attention to the ends. Then I put on a shower cap to keep as much heat in as possible. I left it on for 30 minutes, and every so often, I warmed it up using the hair dryer ( similar to a deep treatment at the salon when you sit under the dryer.) I was very pleased with the outcome! My hair felt so much softer, especially on the ends. Of course, it can't work miracles, but I think with regular trims, and using this weekly, it could be very effective.
