I started using Aveda earlier this year. I dyed my naturally dark hair blonde. The upkeep of the blonde stressed my hair, made it dry, it was always tangled. I really thought I was going to have to cut my hair and start over to get healthy hair again. My best friend suggested Aveda. i didn't see how a topical shampoo was going to fix the damage, but I gave it a try. Within a couple weeks my hair felt healthier. I had more shine and it was softer, the frizz was more controllable. After a couple more weeks, the breakage looked more managed, it blended in to the hairline, and my hair was silky. i also noticed that after a couple months, it seems likem my hair grows a lot faster, and I need to go in for trims more often. I LOVE this shampoo, I can't imagine why I'd want to use any other. It smells great, and my boyfriend uses it as well because the scent is very natural, not to "perfumey," as he puts it. The results speak for itself. i highly recommend this product.
