I use Klorane's oak milk shampoo. You can get it on sasa.com.
It doesn't foam a lot, which is a good thing, because foaming comes from harsh ingredients like sodium laureth sulfate. This shampoo rinses off easily and you're left with soft, clean hair that doesn't tangle.
Once a week, I use Klorane's mango butter hair mask. I smooth a big spoonful of this delicious cream into my hair, avoiding the scalp. Leave it in for 10 minutes (or 20 minutes in a warm towel for deep conditioning), rinse it off, and vibrant, silky hair is guaranteed for the rest of the week.
