Could I use a body hair transplant into linear FUT scar?

Typically, the use of body hair is not recommended for FUE for the following reasons: The hair from the body is thinners and does not grow as long and the scars from the extraction would be more visible if the donor site is on the body. Finally, If the scar tissue at the recipient site is thick, the graft may not take very well. However, since you are talking about a small area covering the scar from the BHT, you can have the donor follicles extracted from discrete areas on your arm and if the density of hair on your arm is thick enough, it could hide any visible donor site scars. I think it is worth a try. 

Hello, and thank you for your question. Yes, you can use body hair if your donor area is not viable. On the body, the door area usually includes the beard or chest hair, but is not recommended as the best option. Consult with an experienced hair restoration surgeon for a complete range of options that are appropriate for your situation.

body hair can be used as a transplant donor, however the quality of body hair, especially of the arms is thin and poor with decreased survival rate to that on the back of your head. Hope this helps!Johnson C. Lee, MD

Hello and thank you for your question. The answer is yes you can use body hair but it is not advisable. Body hair is very thin and will not work well. I suggest use Scalp Micropigmentation (SMP) for better results. Best wishes.Dr. T

I have completed multiple successful FUE procedures placing mainly FUE grafts from the beard into strip scars.  Depending on the length and width of the scar(s), this can be complete in one session.  The graft take is usually good.  With thicker scars, I often will use a small FUE punch to punch out the FUT scar and then place grafts into those punched out areas.  Body hair such as from the arm or chest is also an acceptable area to get donor hair from. 
Also consider Scalp Micropigmentation (SMP) in addition to the placement of grafts into the scar(s) to get optimal results.

One can use body hair into scalp scars but it is not the best approach. The use of Scalp Micropigmentation is far better.
