Can shampooing twice a day affect a hair transplant?

It's perfectly safe to shampoo more frequently than once daily if that's how you stay comfortable in warm weather. At this point, your transplanted follicles should be fully healed, so there's no risk to your results.

 

Washing you hair should not harm transplanted hairs especially after 6 months. If you are concerned see your doctor for a follow up.

You can shampoo twice a day if that solves your problems. At this stage the hair transplants are fixed even the ones that have not grown out yet.

There is very little you can do after four months to adversely affect the final outcome of a hair transplant, and there is certainly no problem with shampooing twice a day. In fact, if it makes you feel any better, I have always instructed my patients to begin shampooing twice a day beginning 24 hours after surgery and continuing at least until all the scabs were gone.I hope this was helpful--Dr. Ballon
