Reviews

Best shampoo ever

"The best shampoo for thick wavy hair, that gently but effectively cleans my scalp and gets rid of any grit, and oil. Smells amazing too! This is the only shampoo that doesn’t dry out my scalp or make it oily. Perfect balance of everything. Keeps my hair so soft and shiny"

Jeannette (2/5)

Works great. . . smells horrible

"After falling in love with the detox shampoo I decided to give this shampoo and conditioner a try. I've only used it a couple of times, but I can definitely see a difference in my hair when I use this versus other shampoos- my hair is much smoother and has some shine. But I seem to be the only person that thinks it smells absolutely terrible. I LOVE the smell of the detox shampoo, but this one. . . . it reminds me of the lingering smell of nail polish remover. I absolutely HATE it, and it lingers for days so I feel like I can't get away from it."
