Will hair stop growing if the scalp is burned?
Generally, whether hair will grow back after a scalp burn depends on the severity of the injury. Mild burns typically do not affect hair growth, while severe burns that damage hair follicles may result in permanent hair loss. If there are concerns, it is advisable to seek medical advice promptly. Detailed analysis is as follows:

If the scalp suffers only a mild burn—characterized by localized redness, slight pain, or a burning sensation without blisters or peeling—and the hair follicles remain undamaged, the scalp can gradually return to normal with proper care, and hair usually regrows normally. During this time, avoid further irritation to the affected area, keep the scalp clean, and consider applying gentle moisturizing and restorative products to aid recovery.
If the scalp experiences moderate to severe burns, with obvious blistering, peeling, or even skin ulceration, the hair follicles may be damaged or destroyed due to high temperature. If the follicles are completely necrotic, hair regrowth in the affected area is unlikely. If follicles are only partially damaged, under professional treatment and long-term care, limited hair regrowth may occur slowly in some cases, though the recovery period is lengthy and outcomes are uncertain.
Immediately after a scalp burn, cool the area under running cold water to reduce temperature, and avoid scratching the injured site. If blisters rupture, signs of infection appear, or no new hair growth is observed over time, seek medical evaluation promptly to assess follicle condition and receive appropriate treatment.
