Yes, both genetics and hormones can affect hair growth.
Genetics play a role in determining the rate and pattern of hair growth. Some people may have a genetic predisposition to slow hair growth, while others may have a faster rate of hair growth.
Hormones can also play a significant role in hair growth. Hormonal imbalances, such as those experienced during pregnancy, menopause, or hormonal changes due to a medical condition, can cause changes in the rate and pattern of hair growth. For example, hormonal imbalances can cause hair loss or hair thinning.
Additionally, medications that affect hormones, such as birth control pills or hormone replacement therapy, can also impact hair growth.
