Love this shampoo for waves!

My hair is susceptible to frizz, and is almost curly in humidity, but looser waves when it's dry outside. This bar adds moisture when I need it (during dry months - I live in the PNW of the US), and tames my frizz during the wet season. Smells great too - not too sweet or perfumy.

Better than expected

I've a head full of mixed curl types from 1C to 3A and always found it hard to define them. I was reluctant at first to try bars as an impatient person, I knew it wouldn't be as easy as using liquid shampoo. It's definitely harder to use for me but once my hair was dry I knew it's well-worth it. I didn't have to use curl cream, curl socks, curler, or even my fingers to define my hair - just used this shampoo bar and the conditioning bar, then air dry - and the curls simply appeared! The best product for curl definition!

Love these curly duo products

I’ve tried other shampoo and conditioner bars and so far, this curly duo from Ethique are my fave — esp for my wavy/curly hair. The balance for my hair is great and my curls stay intact longer.

My favourite

It’s took some time to find the right shampoo, then I have to change with the season. This is reliable and gentle with my scalp. I will miss ethique!
