Sunburn (Scalp Condition)-Hairline Loss Due To Sickness

Hair protects your scalp from the sun’s harmful rays, but if your hair is thinning, you need to protect your scalp with sunscreen on a daily basis, says Dr. Eric Schweiger, M.D., a board-certified dermatologist and hair transplant surgeon at Bernstein Medical -- Center for Hair Restoration in New York City.

Any mild scalp sunburn won’t harm your hair follicles, but exposure that causes blistering can cause scarring and precancer cells, which will harm hair follicles permanently.

The American Academy of Dermatology recommends against indoor tanning because tanning-bed radiation exposure is similar to the sun and in some cases may even be stronger.
