Abstract
In monilethrix, trichoscopy shows abnormalities in terminal and vellus hairs of the scalp. Hair shafts show uniform elliptical nodosities and intermittent constrictions causing regular variation in hair shaft thickness. Hairs bend and break at constriction sites. Horny follicular papules appear as big yellow dots when evaluated on trichoscopy with immersion fluid. Perifollicular scaling and keratotic follicular plugs are be best visible on dry trichoscopy. Differential diagnosis includes monilethrix-like congenital hypotrichosis, pseudomonilethrix, and acquired monilethrix-like hair shaft appearance.
