I received a sample bottle of this in a past Birch Box and I threw it in the shower just in case I wanted to use it someday. I admit that a few weeks went by, and the I finally noticed the little bottle among a bunch of large bottles. I shampooed my hair as usual, the and a small amount of the hair mask. I rubbed it into my scalp and smoothed it through my hair. While I let that soak in, I shaved my legs and finished showering. I rinsed out the conditioner, which actually rinsed out and didn't leave that "when will I know this is rinsed out??" feeling. I towel-dried my hair, then used a blow dryer as per usual. Wow. My hair felt smoother, thicker, softer, and better that it's felt I'm a long time! I didn't use any styling products that day--I didn't have to. My hair was shiny and perfect and I felt great. Now I use this mask about once per week, sometimes a little less. I don't wash my hair every day anyway, and I believe the mask's effects last for a while, even after shampooing and using a regular conditioner. I can't say enough about this product. Probably the first time I've used a hair product that consistently shows obvious results. My hair feels healthy and thicker. It could work for you, so why not try? If not, there are about a thousand other products that promise the same results. But I think you might be pleasantly surprised with this stuff.
