Another possible factor is Polycystic Ovary Syndrome (PCOS), a hormonal condition that affects many women. One of its features is hirsutism, meaning increased hair growth in areas where women typically have little. PCOS can also involve irregular periods or skin changes, but chin hair alone does not mean someone has this condition. Only proper evaluation can confirm it.
The key is awareness, not worry. Paying attention to sudden changes and responding thoughtfully helps you decide when self-care is enough and when professional guidance might help. Understanding your body builds confidence—both in your health and in how you care for yourself.
