why some men lose hair and others don't

Hair shedding is a natural process that every man goes through. On average, men shed 50 to 100 hairs a day as part of the normal hair growth cycle. However, for many men, hair shedding can feel more noticeable—especially when it’s combined with thinning or balding. Understanding why hair sheds and what factors contribute to it is the first step towards getting the right treatment.

Many men experience increased shedding or hair thinning due to a condition called androgenic alopecia, more commonly known as male pattern baldness. This is the most common cause of hair loss in men and is largely genetic. It’s driven by a hormone called dihydrotestosterone (DHT), which shrinks hair follicles over time. This leads to shorter, finer hairs and eventually, follicles stop producing hair altogether. If you notice a receding hairline or thinning at the crown, it could be due to this genetic condition. Topical finasteride is a medication that is commonly used to block DHT to help men regrow hair.

Beyond genetics, lifestyle and health factors also influence hair shedding. Stress, whether physical or emotional, can trigger a condition called telogen effluvium, where more hairs than usual shift into the resting phase and fall out a few months later. Illness, surgery, sudden weight loss, or even a poor diet can also cause this temporary increase in hair shedding.

Nutrition plays a key role in healthy hair. If your body isn’t getting enough protein, iron, zinc, or vitamins like D and B12, it may redirect its resources away from hair production. 

Hair care habits also matter. Using harsh shampoos, wearing tight hats regularly, or pulling hair back in tight styles (like man buns or braids) can lead to breakage or traction alopecia—a type of hair loss caused by tension on the scalp. 

Certain medications and medical conditions can also lead to shedding. Thyroid disorders, autoimmune diseases, or scalp infections can also be culprits.

In conclusion, while hair shedding is a normal part of being a man, it can become more noticeable due to genetics, lifestyle choices, or health issues. Knowing the causes helps men make better decisions about grooming, nutrition, and when to seek professional advice. If hair loss becomes excessive or persistent, take our assessment to help identify the cause and find the right treatment.
