Alopecia areata, colloquially known as "ghost shaving," is often associated with immune factors. It is important to rest, ensure adequate sleep, manage poor emotions, and avoid anxiety. Additionally, consuming black foods can benefit hair regeneration. Topical treatments include minoxidil spray, dermatan sulfate chondroitin polysulfate cream, pimecrolimus cream, etc., along with oral intake of cysteine tablets, vitamin B6 tablets, and compound glycyrrhizin tablets. Support can also come from other traditional Chinese medicine treatments or physical therapies, such as local tapping with plum blossom needles, and the assistance of 308-nanometer excimer laser and intense pulsed light, all of which can improve scalp microcirculation.
