Does PRP work for hair loss due to Trichotillomania?

Yes, PRP can give you some improvement along with progesterone or transplantation.  I suggest you see a cosmetic dermatologist who specializes in hair loss for a formal consultation. Best, Dr. Emer

In my opinion, PRP has the ability to increase the speed of hair re-growth and thicken the hair. With trichotillomania, one must stop with the manipulation of the hair in order to see any improvement. Once this has been accomplished, the PRP can increase the speed of re-growth and thickness of the shaft, provided that the repeated trauma has not cause scarring of the follicles. Should the follicles be scarred, there will be no effective treatment other than transplantation.  Good luck.
