Immediate hit: Chi Silk Infusion sample
My hair was already shiny and moisturized but I put just about a dime size amount of this in my hair and blow dried and OMG. My hair said "Oh my my, oh hell yes!". It just feels better. It has more body and bounce and I really like running my hands through it. Also, from the time I started to shampoo my hair until the time I finished my blow dry I lost under 30 hairs - mostly shed, not broken. For some people this is still a lot but for me, as a fine-strand relaxed head, this is super. There were less than 10 hairs in my hair catcher in the shower after shampooing/conditioning and there were about that many after combing and blow drying on the floor. This stuff is a keeper... I know it's on the expensive side but if I'm using a dime size amount with each wash a 6 oz could last me a whole year. Plus I'm sure I can find it at a good price for 6 oz (under $20).
I'm going to try this Biosilk next. I really didn't ever think I'd like serums but this may be a nice addition to my routine, and it only takes a few seconds to apply. If the next few I try aren't as good as this Chi then I'll just stick with that.
