Alopecia areata, commonly known as "ghost shaving," often manifests itching symptoms which usually indicate a local inflammatory response. It requires comprehensive treatment including regulation and immunity, attention to rest, ensuring adequate sleep, and maintaining a good mood. It's advisable to consume more black foods and take oral medications like compound glycyrrhizin tablets and folic acid tablets. For the affected alopecia areata areas, topical applications of minoxidil spray, dermatan sulfate chondroitin sulfate cream, or pimecrolimus cream can be used. Additional physical measures include treatment with fractional laser and helium-neon laser radiation. If necessary, local injections of compound betamethasone injection solution or triamcinolone acetonide can be administered to achieve anti-inflammatory effects.
