I got a FUE hair transplant late April of last year for the temples of my hairline. Although my overall results of my hair line is ok (a bit still not as dense), some of my hairs are along the hair line are growing in with bumps at the root. It looks kinda pluggish. My doctor prescribed my 1% Clindamycin Phosphate twice now and i still have them. What is the cause of certain hairs looking "pluggy" and what are my options to fix this?
