Experience is a must here for African-American hair transplants. African-American hair grows far differently than Caucasian hair. Varying the angles and placement helps insure a far better result. Also, because of generally darker pigmentations in the skin, scarring wants to be avoided. New York hair restoration specialist Dr. Gary Hitzig has developed ACell MatriStem treatment for hair transplants, which rescues dying hairs, "clones" hair and blocks fibroblasts that cause scarring.
