Great for oily hair.

I have oily hair. i bought this product becasue its sulfate and paraben free. with Charcoal to help "detox" your hair. The Smell is subtle but manly. but i enjoy it. Its a very effective on my oily hair. i used to have to wash my hair daily becasue of grease build up but now i can go 2 days without washing my hair.

Horrible!

Herbal Essence bio:renew detox black charcoal shampoo is possibly the worst shampoo I've ever used. It contains both SLS & SLES in the top 3 ingredients. They are both know irritants and possible carcinogens. The list of ingredients contains many other products that have the same problems. Although they are paraben and silicone free, the ingredients are far from clean. The shampoos lathers up, but the smell is brutal! If you like to be smelled from across the room, then this is for you. It smells like Percil laundry detergent. After a couple washings, the smell was finally going away, but it hasn't been easy. I washed my hair with vinegar to finally get the smell out. I would not buy this, recommend it, or stand anywhere near someone who uses it!
