Scalp pain when touched can be caused by several factors, including trauma (like bumps or cuts), skin conditions such as dermatitis, psoriasis, or infections like folliculitis. It may also be related to hairstyles that pull the hair tightly, leading to scalp tenderness. Other causes include infestations (lice), headaches or migraines, sunburn, or inflammation of blood vessels such as temporal arteritis. Often, scalp pain is accompanied by symptoms like redness, itching, flaking, or bumps. Treatment depends on the underlying cause and may include avoiding irritants, using medicated shampoos, or seeking medical treatment for infections or other conditions.
