What is Pili bifurcati?
Pili bifurcati is a very rare condition that affects the structure of hair. The name comes from Latin words meaning 'split' or 'forked' hair. In this condition, individual hair shafts split into two separate branches along part of their length, then come back together again, forming a fork-like shape. This splitting happens within the hair shaft itself and can be seen clearly under a microscope. The rest of the hair structure appears normal. The main sign of pili bifurcati is unusual-looking hair that may appear slightly rough, dull, or fragile. The hair does not grow or behave quite like typical hair. In most reported cases, the condition has been noticed in children, though it can appear at different ages. It is considered a structural hair shaft disorder, meaning the problem is in how the hair is built, not in the scalp or hair follicles themselves. There is no specific medical treatment needed for pili bifurcati in most cases, as it is generally a cosmetic concern rather than a serious health problem. Gentle hair care practices are usually recommended to reduce breakage. The condition does not appear to cause pain or affect overall health, and in some cases it may improve over time.
Key symptoms:
Hair shafts that split into two branches and rejoin, visible under a microscopeHair that looks dull or lacks normal shineHair that feels rough or coarse to the touchIncreased hair fragility or breakageUnusual hair texture compared to other family members
