Tinea capitis is an infectious skin disease caused by fungal invasion of the scalp hair, and is clinically classified as tinea capitis, tinea nigra, or tinea alba, of which tinea alba is the most common and can be complicated by tinea suppurativa. Tinea albuginea starts as a limited scaly patch on the scalp, then gradually expands and is followed by small patches of the same nature in a satellite-like distribution. The diseased hair is gray and dull, a white sheath is visible at the root of the hair, and the diseased hair is often broken at about 0.5cm out of the scalp. The mother and child spots, the white sheath and the broken hair form the clinical characteristics of leucoderma. By direct microscopic examination of the fungus, round spores can be seen in piles or mosaic arrangements outside the lichen planus hair. Bright green fluorescence is seen under filtered ultraviolet light examination (wood lamp), and the causative fungal species can also be determined by fungal culture. Tinea capitis often requires systemic treatment and can be treated with 15-20 mg/(kg.d) of ashwagandha, given orally in 3 doses over a period of 3-4 weeks. The disease is often seen in childhood and can be cured spontaneously after adolescence.
