I am not so sure I have ever rated a shampoo with 5 stars before, and I’d give this an even higher rating if it were an option. Prior to discovering and trying this, I only washed my roots...

This is my go-to shampoo. Sometimes, I feel that it doesn’t get my hair clean enough, but will let it sit or massage it in for another minute, and it feels more fully clean. This is the only...

This shampoo is the best I've used for the condition of my hair now, which is bleached. It changed the texture of my hair, and my hair is actually less damaged now when I highlight it, like it...

Nothing special. I have fine, long hair. Nice rice lather, but the smell is nothing to write home about, nothing special about this shampoo (or condition for that matter). Especially for the price...
