After hair transplant surgery, why it is necessary to highly keep the scalp from sun exposure

Hair transplant surgery or hair restoration surgery is a very difficult procedure. The surgeon gives numerous advice and precaution tips to get the best effective results. One of the precautions is to avoid going in the sun exposure after hair transplant for 6 weeks. It is because hair graft endurance is totally dependent on the implanted new hair follicles, which are slowly connected to a new resource of blood supply. 

Therefore, without that occurring accurately, whether from affected from UVA or other sources, they will be damaged.

So the possibility of harsh UVA rays is the cause of sunburn and/or exposure below the outer layer of transplanted scalp tissue will damage both the hair graft tissue plus the underlying new hair follicles. It is why because the healing procedure in the deep skin layers of the scalp or lower dermis is very slower than the upper epidermis skin layer. It is absolutely a tragic situation for those patients, who underwent from the painful hair restoration surgery. 

For the prevention of this condition, always wear a good-quality cap or hat that properly covers the newly hair transplant area when it is exposed to the harsh UVA rays. Patients always ask that is hair transplant permanent, so yes it is, but you should properly care your transplanted area because the high UVA rating directly burn the follicles yet a complete cover with a good-quality hat stops this possible damage from occurring. 

The majority of the hair transplant surgeon Most hair restoration physicians want their hair transplant patients to avoid the straight exposure to harsh UVA waves for at least 12 weeks post-op, some surgeon advice 5 months or some advice more than 7 months depend upon the patient’s scalp condition.
