Reviews

The pump doesn't work so well

"I love this shampoo - it's great for my curly hair and smells amazing - but this pump bottle is not so great. The pump doesn't work very well. Something about the mechanism means the part connected to the bottle (not the part where the actual shampoo comes out) leaves it always covered in shampoo, and makes it harder to pump. I'm constantly having to clean the bottle, which isn't an issue I have with my other pump based products. I will be repurchasing the shampoo but not this particular bottle."

— Sophie M. (3/5)

My hair smells amazing and is so soft

"I’ve tried numerous brands and this is the best for my hair by far. I am 53 and am noticing that along with hair loss, the texture of my hair is changing. Also, my sense of smell is heightened, so this shampoo and conditioner duo helps to clean, condition and make my hair smell amazing for a few days at a time."

— Chetna F. (5/5)

"Good shampoo! Love the smell . pretty expensive though"

— Zayra (5/5)

Can’t use any other shampoo now

"I recently tried a different brand after using this for a while and it just didn’t compare, I immediately had to buy this again and get back to it. It smells amazing, has a great lather, and has made my hair so healthy"

— Emily M. (5/5)
