I have dry, frizzy, coarse hair that is naturally wavy/curly. Whenever I blow out my hair straight, I usually pre-condition, shampoo, post condition, blow dry, and touch up with a flat iron. I bought this as an alternative to my usual post conditioner (Pantene) and used it for the first time today. After shampooing, I put a generous amount of this stuff on towel-dried hair, then covered it with a cap, leaving it in for about 15-20 minutes. Rinsing it out was a little weird because it made my shower floor a bit slippery. Can't say that the results are magical, but they are OK and on par with my regular Pantene conditioner. Oddly, one of the ingredients in this treatment is isopropyl alcohol, which is drying to the hair, so I am a little hesitent to use it constantly. As a smoother, it does seem to help, so I'll probably buy it again and rotate it with Pantene. Not bad, but not as magical for me as it has been for other reviewers.
