I tried the serum after my experience with the shampoo and conditioner (AMAZING! Moisturized like crazy.) The serum works wonders. I noticed a difference in my hair right away. Aside from looking healthier it was sooooooooo soft... my hair felt like silk. Cliche but true. I have since let everyone I know about the serum and it works for all of them, all different hair types and ethnicities. Be careful to only use as much as it directs (three-four drops.) Otherwise your hair might get weighed down and look overly shiny and greasy.
