Pili multigemini

Pili multigemini, also known as "compound hairs,"[2] is a malformation characterized by the presence of bifurcated or multiple divided hair matrices and papillae, giving rise to the formation of multiple hair shafts within the individual follicles.[3][4]

Description

The name describes a condition where several separate hair fibers bunch together and emerge from the skin through a single hair canal. The hair looks like a bunch of flower stalks in a vase. Pathology shows that deep in the skin several dermal papilla are closely situated with each producing a fiber, but these separate hair follicle bulbs combine together into one hair canal towards the skin surface. Folliculitis can sometimes be associated with this condition.[2]

Treatment

Electrolysis will permanently remove pili multigemini. Depilating laser treatment has been suggested to improve symptomatic pili multigemini.[5]
