Great for Curly Hair

Doesn't work for me

I didn't get on with this shampoo, it didn't lather as well as others and left my hair feeling odd.

I don't think my curls were any better than when I use Heli Kiwi or the Oaty shampoo.

Also not a fan of coconut fragrance, but tried for the potential curly hair benefits.

Love this

Absolutely love Professor Curl. I really didn't think that I could find a shampoo to top "Frizz Wrangler" but Professor Curl has done the job, my definite favourite.
