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"

— Rachael S. (5/5)

Is there a fragrance free version?

"Love the shampoo and conditioner but fragrance is bothering me and my family. Any chance there’s a fragrance free version available?"

— R (5/5)

Love this conditioner! My hair

"Love this conditioner! My hair feels amazing after using it with the shampoo! It rinses out easy and leaves my hair feeling so soft! I have curly, thick, coarse hair but this makes it feel amazing! I haven’t noticed as much frizz either!"

— Melanie F. (5/5)

Love it! Little problem.

"This shampoo is perfect but the pump on the conditioner did not work!"

— Ann P. (5/5)

Smells great

"I was hoping a little would go a long way but with thick coarse hair it took a lot to get a comb through it so price wise it’s not a good match for me"

— Lana M. (4/5)

"Has been a game changer for my hair"

— Christina (5/5)

"Im a frequent buyer"

— Regina (5/5)

— Melanie F. (5/5)
