After transplant, can I use hair fiber to cover the transplanted area?

You can use hair fibers few days after surgery.  It is always a good idea to follow up with your doctor for a recheck if you have concerns.

Yes, these are very popular and very good. Just do not use them on the first few days.  They can help hide the redness very well until this resolved on its own.  It can also make up for the shedding and shock you sometimes see from the transplant. 

Hair fibers can be safely used starting day 4-5 after the transplant. Meticulous daily washing off of the fibers is critical.
