Chin hair growth occurs in three phases: anagen (active growth), catagen (transition), and telogen (resting/shedding).
In the anagen phase, hair receives nutrients and grows steadily before stopping in catagen and eventually falling out in telogen.
Hormones, especially androgens (male hormones present in both men and women), strongly influence chin hair.
Elevated androgen levels or increased sensitivity to them can make facial hair more noticeable.
Genetics also play a major role. Some people inherit more hair follicles or higher follicle activity,
leading to increased chin hair. If facial hair is common in your family, you’re likely to see similar patterns.
Overall, chin hair growth results from a combination of hormonal and genetic factors. While it’s a normal
biological process, sudden or significant changes in facial hair may be worth discussing with a healthcare provider to rule out underlying conditions.
