Is it normal for public hair to fall out when you're a young adult? only a few hairs a day and with no other symptoms?

We lose between 50-100 hairs a day and you can lose pubic hairs at your age. However if the pubic hair turns prematurely white or becomes noticeably too thin, a medical disorder is usually responsible such as thyroid disease. Generally in medical disease other body areas lose hair abnormally also. If you still have concerns consult a dermatologist for evaluation and advice& any appropriate testing
