Regular use of hot tools, such as hair dryers, flat irons, and curling irons, is not recommended when growing hair after a hair transplant. High heat damages the newly transplanted hair follicles, causing them to fall out or weaken. It is important to be gentle with the hair during the post-transplant recovery period to ensure proper growth. It is important to weigh the potential damage against the desired look while using hot tools to provide a desired styling effect. Alternatives such as air drying and low heat on hot tools are considered.
