Is it possible to use beard hair to restore eyebrows?

One must worry about scars from the punches to extract the follicles on the face if beard is the donor site. Hair from the scalp is preferable. 

I would recommend against using beard hair for an eyebrow transplant. You want the eyebrows to lay flat against the face and I fear beard hair may be curly and too coarse and look unnatural. I would strongly recommend using hairs from the scalp preferably finer haired areas of the scalp. 

Dear lucatThank you for your question. I would advise taking the donor hair from the back of your scalp. Beard hair is typically more coarse than the hair on your head therefore it may make it look slightly odd. Please ensure you see a board certified surgeon and look at their before and after pictures.All the best

Yes, this is possible. However if your beard hair is coarser than your eyebrow hair, getting it transplanted may end up looking odd and not what you would want an eyebrow to look/feel like.

It is possible, however it is best to use the hair from the donor area on the back of the head as it will match your eyebrow hair better. Hair taken from the beard is not similar to eyebrow hair and therefore can look unnatural. Eyebrow transplants need to be done in a very specific way so that the results look as natural as possible. 

Yes, one would use beard hair for eyebrows, but the character of the hair may be a challenge in the beard is coarse and curly
