Why do some of the hair follicles in my underarms have more than one hair growing out of them?
It's not uncommon to have multiple hairs growing out of a single hair follicle, and it's not a cause for concern. This phenomenon is called "polytrichia" and can occur anywhere on the body, including the underarms.
There are a few factors that can contribute to polytrichia, including genetics, hormones, and certain medications.
- Genetics: Some people are simply more likely to have multiple hairs growing out of a single follicle. This is often a hereditary trait.
- Hormones: Hormones can also play a role in polytrichia. For example, high levels of testosterone can lead to an increase in hair growth, including the growth of multiple hairs from a single follicle.
- Medications: Certain medications, such as steroids and some birth control pills, can also cause polytrichia.
In most cases, polytrichia is harmless and doesn't require treatment. However, if you're concerned about the appearance of your underarms, you can talk to a dermatologist about treatment options.
