Q: I am a 65 year old female who has recently experienced thinning hair and I’ve heard of PRP treatments. Is PRP safe and does it work for older people? — R.E., Upper East Side, NY
A:PRP (Platelet Rich Plasma) is safe for persons of any age, although we don’t administer it to pregnant women and those under 18. It can be helpful as long as the person has enough miniaturized hair for it to work on. It will not work on a totally bald area of the scalp.
