Why is there a particularly long hair on my arm?
Long arm hair is often associated with genetic factors. Some cases are attributed to excessive secretion of male hormones or pituitary diseases. For excessively long arm hair, laser treatment is often effective in most cases. Since hair follicles have a growth cycle, more than 3 treatments are often required to achieve satisfactory hair removal results.
1. Genetic Factors: Many patients have a family history of long arm hair. If parents have long arm hair, their children are likely to have the same trait.
2. Excessive Male Hormone Secretion: After puberty, excessive male hormone secretion stimulates excessive hair follicle growth, resulting in longer arm hair.
3. Diseases: Conditions such as pituitary tumors and adrenal hyperfunction can also lead to long arm hair.
Laser hair removal is currently the best method for permanently removing long arm hair with minimal side effects. Since hair follicles have growth and resting phases, laser hair removal typically requires about 3 treatments. Each treatment should be spaced out by one month. It is recommended to visit a reputable hospital's dermatology department for treatment under the guidance of a doctor.
