I've use the regular shampoo...EXTREMELY CONCENTRATED! Use very little goes very-long way! Cleans well as & really opens the 'pores' of the hair shaft for proper conditioning.
Without doubt, this shampoo is the only one that gives my hair body and shine, while accentuating my natural waves. I have not been able to find anything that even compares to this one.
I love the redkin conditioner, but for this shampoo, it was too heavy on conditioner and weighed my hair down. It would be great for very dry, dense curly hair.
