5. Rare hormonal or medical causes

In uncommon cases, increased chin hair may be linked to:

• Adrenal gland disorders

You should consider evaluation if chin hair is:

• Suddenly increasing quickly
• Accompanied by irregular periods
• Associated with acne or deepening voice

A woman’s chin hair is most often:

• Normal genetics or aging
• Sometimes a sign of hormonal imbalance (like PCOS)
• Rarely a sign of serious disease
