It's most likely because you're going through puberty, which is a totally normal time for body hair to increase.
Understanding Hair Growth During Puberty
Puberty typically starts for girls between the ages of 8 and 12, and this is when significant hormonal changes begin. These hormonal shifts, particularly the increase in androgen hormones like testosterone (which girls also produce, just in smaller amounts than boys), are primarily responsible for the increase in body hair. This hair growth is a secondary sexual characteristic, meaning it's a physical change not directly involved in reproduction but signals sexual maturity.
Where You Might Notice More Hair
- Pubic Hair: This is often the first noticeable change.
- Underarm Hair: Hair in the armpits usually follows pubic hair.
- Leg and Arm Hair: Existing hair may become thicker and darker.
- Facial Hair: Some girls may notice fine, light hair on their upper lip or chin.
Is It Normal?
Generally, yes, increased hair growth at 12 is completely normal. However, the amount and distribution of hair can vary greatly from person to person due to genetics, ethnicity, and individual hormone sensitivity.
When to Seek Medical Advice
While increased hair growth is usually normal, there are situations where it's a good idea to consult a doctor. Consider seeking medical advice if:
- Hair growth is excessive or sudden: Rapid or excessive hair growth, especially if it's accompanied by other symptoms.
- Other symptoms are present: Symptoms like irregular periods, acne, deepening voice, or male-pattern baldness can indicate a hormonal imbalance.
- You're concerned: If you are significantly distressed by the amount of hair growth.
These symptoms could potentially indicate conditions like:
- Polycystic Ovary Syndrome (PCOS): A hormonal disorder common in women.
- Congenital Adrenal Hyperplasia (CAH): A genetic condition affecting the adrenal glands.
- Tumors: Rarely, a tumor could cause increased androgen production.
Important Note: These conditions are relatively rare, and most likely, your increased hair growth is simply a normal part of puberty. However, it's always best to err on the side of caution and consult a healthcare professional if you have any concerns.
