New Delhi: Losing up to 100 strands of hair a day is normal. But noticeable thinning, a receding hairline, or excessive shedding often signals an underlying issue. Male hair loss is common, yet rarely caused by just one factor. Understanding the root causes is key to managing it effectively.
Genetics is the leading cause. Androgenetic alopecia, or male pattern baldness, occurs when hair follicles are genetically sensitive to DHT (dihydrotestosterone), a byproduct of testosterone. Over time, DHT shrinks follicles, producing thinner, shorter hair until growth stops altogether. This can begin in the late teens or early twenties, typically showing up as a receding hairline or thinning crown.
Hormonal imbalances also play a major role. Elevated DHT, thyroid disorders, and insulin resistance can disrupt the hair growth cycle. Thyroid dysfunction affects how quickly follicles regenerate, while insulin resistance can increase androgen levels, accelerating hair thinning. Because symptoms may be subtle, blood tests often reveal more than a simple scalp check. (ANI)
