Introduction
Scalp bumps may be caused by folliculitis, seborrheic dermatitis, allergies, or other reasons. Appropriate treatment should be chosen based on the specific cause. If scalp hygiene is inadequate, bacteria can easily grow on the scalp, leading to folliculitis and resulting in scalp inflammation, redness, and swelling, which manifest as bumps. It is important to seek timely medical evaluation for a thorough examination and receive prompt treatment according to the condition.
Scalp bumps may be caused by folliculitis, seborrheic dermatitis, allergies, or other reasons. Appropriate treatment methods should be selected based on the specific cause. Detailed analysis is as follows:
1. Folliculitis
If scalp hygiene is inadequate, bacteria can easily proliferate and lead to folliculitis, causing scalp inflammation and redness, which results in scalp bumps. Under a doctor's guidance, medications such as erythromycin ointment, mupirocin ointment, or ketoconazole cream may be used for treatment.
2. Seborrheic Dermatitis
Abnormal sebum secretion or microbial infection on the scalp may trigger seborrheic dermatitis. Inflammation can lead to the formation of light yellow crusts, resulting in scalp bumps. Under medical supervision, treatments may include isotretinoin gel, dexamethasone ointment, or itraconazole cream.
3. Allergy
Individuals with an allergic constitution may develop scalp allergies upon exposure to allergens, leading to blisters and scalp bumps. Under a doctor’s direction, antihistamines such as loratadine tablets, mizolastine sustained-release tablets, or cetirizine tablets may be used for treatment.
In addition, scalp bumps could also result from scalp abscesses. It is important to seek timely medical evaluation at a hospital for thorough examination and appropriate treatment.
