Reviews

fine dense 4C hair

"This shampoo is really hydrating and moisturizing but still cleansed my scalp well. I also have the detox shampoo and love that as well this is definitely not as drying. I did 2 shampoos and my scalp felt so clean and hair still not too dry or tangled. I paired it with the conditioner and it my hair felt amazing after. I have shorter type 4 hair."

— Ayo W. (5/5)

"Even though I knew the size ahead of time, it still seemed incredibly small for the price. Would love a larger option."

— Kathy (3/5)

Smells like a florist shop

"This made my hair smooth and shiny but I smell like the worst floral perfume. The smell reminds me of the elderly. This is not worth the money for that scent."

— JBRAN (2/5)

Messy Packaging

"I love this product, but once again the packaging is not easy to use. Same with the pump bottles… I waste so much product dealing with the packaging"

— Sam G. (3/5)

Over powering scent

"As a hairdresser, I liked the thickness of the shampoo and conditioner. However, the smell was so overwhelming. I had to wash my hair again with something else, as well as deep condition because my hair felt like hay after using it."

— Jamie S. (2/5)

Thick Shampoo

"Excellent smell! Excellent quality. Love this product for everyday cleansing"

— Amy K. (5/5)
