I love this Shampoo. I bought the shower set which includes the conditioner and body wash also. I have thin to medium hair and have always had issues finding a shampoo and conditioner that my hair liked. Either it ends up looking greasy or dull or incredibly frizzy. And even if it seems to work in the beginning, it starts to be less effective over time. I also have issues with split ends and have tried brands that promise less breakage with little result. Then I bought Arbonne and it is the best shampoo and conditioner I've ever used. My hair actually likes it! It looks healthy and shiny. It has also been a long time since my last trim and yet no split endage to be seen. I've been using this shampoo for over a year and my hair still hasn't gotten sick of it. It is a little pricey, but definitely worth it. Effectiveness Very, very effective. It nourishes and moisturizes my hair and keeps it looking fresh and healthy. Scent It has a very nice light scent, slightly citrus-y.
