After a certain number of days, it will be okay to resume blow-drying your hair after a hair transplant. We do suggest not doing any blow drying over the first several days, two to three days in other words, after the procedure. The very next day after the procedure, most patients do return for a quick check-up and hair wash at our doctor’s office to ensure that everything looks good and is healing well. But, before using a blow dryer please contact and speak with a nurse or doctor at your specific doctor’s office to ensure that it is safe.
