I also had a great experience with copa - - with the exception of their mailing process, which was infrequent and inconsistent.
I am bi-racial. Relaxers MURDERIZE my hair. They are all too strong. I always ended up with my hair broken off and a scalp full of burns (yes even from "no lye" relaxers).
Copa was a godsend, as it did just what it advertised. It loosened my curls. For a good two years I was rocking the *** out of my nice smooth frizz free spirals.
I miss Copa so much it's not even funny....although now that I'm pre-menopausal, the texture of my hair has softened even more.... I would still buy Copa though. If anyone knows were I can find it PLEASE DO TELL!
Reason of review: Good quality.
I liked: Everything about the product.
I didn't like: Inconsistent delivery.
