Q: Is it true that smoking is bad for a hair transplant and why? P.P. – N.Y., N.Y.
A: Smoking causes constriction of blood vessels and decreased blood flow to the scalp, predominantly due to its nicotine content. Also, carbon monoxide in smoke decreases the oxygen carrying capacity of the blood.
These factors both contribute to poor wound healing after a hair transplant and can increase the chance of a wound infection and scarring. Smoking may also contribute to poor hair growth.
