I would like to know if the donor hair in a hair transplant surgery grows again. What are the reasons for a oily scalp and how to do I control it?
Once donor hair is removed, it does not grow back. The reason hair transplant surgery is a successful procedure is because the derma papilla (DP) cells (cells responsible for hair growth) and hair follicles are harvested from the donor and transplanted into balding areas. Because they no longer exist in the donor region, hair regrowth in the donor will not occur.
Surgical hair restoration is done in such a way that existing hair is meant to cover the evidence of scarring. Follicular unit hair transplantation (FUT) will create a pencil thin linear scar under the best of circumstances and is usually concealed quite well by existing hair even when worn relatively short. Scar stretching risks exist so be sure to speak with your surgeon about this. During the follicular unit extraction (FUE) method, follicular units (hair groupings as they occur naturally) are removed one by one leaving a tiny round white scar which under optimal circumstances aren't noticeable even when the hair is worn quite short. Visible scarring will vary depending on donor hair density, the size of the tool used to extract the follicles, the length you wear your hair, and healing characteristics.
To answer your second question, some scalps are just naturally oily. There are shampoos and conditioners designed for men and women with an oil scalp. This usually helps keep it under control.
