The 8 Causes of Men’s Hair Loss – And What You Can Do About It
Have you looked in the mirror lately and noticed your hairline getting thinner? You're not alone. Many men in San Jose and beyond are dealing with hair loss. While it can be frustrating or even scary, knowing what causes it is the first step to fixing it.
Let’s break down the top 8 reasons men lose their hair—in a way that’s easy to understand.
1. Genetics (Male Pattern Baldness)
This is the most common cause. If your dad, grandpa, or uncle lost hair, you might too. It often starts with a receding hairline or thinning at the crown.
2. Stress
Big life changes like a new job, a breakup, or moving can cause stress. That stress can shock your hair and make it fall out.
3. Hormonal Changes
Testosterone turns into DHT (a strong hormone) in your body. Too much DHT can shrink your hair follicles, making it hard for hair to grow back.
4. Poor Diet
Your hair needs fuel. Not eating enough protein, iron, or vitamins can make your hair weak and more likely to fall out.
5. Medical Conditions
Things like thyroid problems, autoimmune diseases, or scalp infections can mess with your hair growth.
6. Medications
Some medications for blood pressure, depression, or cancer may cause hair loss as a side effect. Always talk to your doctor if you think your meds are causing changes.
7. Hairstyles and Hair Care Habits
Wearing tight hats or ponytails, or using harsh chemicals, can pull or damage your hair over time. This is called traction alopecia.
8. Aging
As we get older, our hair naturally thins out. It’s a normal part of life, but that doesn’t mean you have to live with it.
What You Can Do
The good news? Many of these causes can be treated or managed. Here’s how:
Eat a balanced diet full of lean protein, fruits, and veggies
Lower your stress with daily walks, breathing exercises, or talking to someone
Use gentle hair products and avoid tight hairstyles
