The concentrated formula goes a long way. Depending on hair length and thickness, apply one or two pumps of shampoo to your and work into a lather. Work into wet strands and rinse thoroughly and follow with Number 4 Hydrating Condition.

Nothing special

I have tried both the volumizing and hydrating shampoos by this brand and I wasn't impressed with either. They didn't smell particularly great, and really seemed to make no difference at all in my hair. The packaging it completely lack luster as well. This product is just nothing special.

Great for color treated hair

Just colored my hair and its not super dry! Very nice shampoo, pleasant smell and like that it is 100% vegan. Also I am free of any "stylistic sin"!

Very nice

I don't wash my hair often and when I do I need a strong yet gentle shampoo to get the job done. This shampoo got my hair soft and shiny after one wash. Brilliant!

Good poo

I liked how this shampoo smelled and felt. It left my hair clean and soft. I think I could make a better overall opinion had I sampled it with the counterpart conditioner. I just wish it weren't so expensive.

loved the feel, not the smell

I liked the texture of this shampoo, and the fact it was sulfate free. It made my hair very soft, however the scent reminded me of my grandfather's cologne.
