When multiple hairs grow in one follicle, it is called pili multigemini. This condition is not usually harmful and can happen anywhere on the body where hair grows. The exact cause of pili multigemini is not known, but it is believed to be genetic. The follicle is capable of producing multiple hair shafts due to the production of stem cells within the follicle, which can divide and create multiple hair shafts. Additionally, follicles can go through a process called follicular miniaturization, where the stem cells within the follicle begin to produce smaller and finer hairs until, eventually, multiple hairs can emerge from the same follicle.
There are no specific product details, ingredients, or materials mentioned in the search results related to pili multigemini. However, good grooming habits and proper hair care, such as regularly washing and conditioning hair, using a wide-toothed comb, and avoiding tight hairstyles or certain shaving practices, can help prevent multiple hairs from growing in one follicle.
