77 views

Underarm hair and other body hair often stop growing or slow down in growth as you get older due to hormonal changes. These changes can lead to reduced activity in hair follicles, causing the hair to become finer or fall out. Androgen levels decline with age, which affects the hair growth cycle, making the growing phase shorter and the resting phase longer. This natural process is common and generally not a cause for concern.

FAQs & Answers
