OTC products are often effective for mild to moderate scalp psoriasis. Coal tar shampoos slow skin growth and reduce scaling. Salicylic acid helps loosen and remove thick plaques. Mild topical corticosteroids can reduce itching and inflammation when used carefully. Follow product instructions closely, and speak with a pharmacist if unsure which option is best.
7. When to See a Doctor
Even with home care, some situations require medical evaluation. Seek help if symptoms worsen, do not improve after several weeks, or interfere with sleep and daily routines. Signs of infection such as spreading redness, pus, fever, or severe pain need immediate attention. A dermatologist can confirm the diagnosis and recommend prescription treatments such as stronger steroids, medicated foams, or light therapy.
