Alopecia areata, commonly known as "ghost shearing", is often related to immune factors in its causes and mechanism of onset. It is important to rest and provide symptomatic treatment with immune modulation. Generally, recovery can be expected within about a month. Oral medications such as cysteine tablets, folic acid tablets, vitamin B6 tablets, and pimecrolimus granules can be taken. In the area affected by alopecia areata, topical application of dermatan sulfate polysaccharide cream, tacrolimus ointment, combined with the use of minoxidil solution is recommended to promote local circulation and thereby facilitate hair regrowth. Additionally, other physical therapy measures can be supportive, including traditional Chinese medicine treatments such as plum-blossom needle tapping and local intense pulsed light therapy. (Medication should be used under the guidance of a doctor.)
