The average human head has about 100,000 hairs, but this number decreases with age due to genetics, hormones, and health conditions. Understanding how hair grows—and why it falls out—can help you spot early signs of hair loss and find the best treatment to keep your scalp healthy.
Hair shedding is completely normal—up to a point. While losing between 50 and 150 hairs daily is part of a healthy hair cycle, sudden or excessive hair loss may signal an underlying issue. Learn to tell the difference and discover what steps to take if shedding becomes a concern.
Finasteride treats hair loss by blocking DHT, a hormone linked to balding. Available in oral (FDA-approved) and topical forms, it effectively promotes hair growth. While oral finasteride may cause systemic side effects, topical versions show promise with fewer risks. Both require prescriptions and work best with consistent, long-term use.
