Hair loss isn’t always about hair care. Learn 5 science-backed causes of hair thinning in your 30s and 40s—like hormones, insulin resistance, and thyroid imbalance—and how to address them naturally.

It’s Not Just Shampoo: 5 Hidden Reasons You’re Losing Hair

Seeing more hair in your brush lately? You’re not alone—and it’s probably not your fault. Hair loss in your 30s or 40s is often linked to deeper health signals.

1. Hormonal Imbalances (DHT)

Dihydrotestosterone (DHT) is a hormone that shrinks hair follicles. Both men and women produce it, and when levels rise, hair growth slows. DHT blockers may help reduce this effect.

2. Insulin Resistance

Extra belly fat often signals insulin resistance. This can boost androgen levels—like DHT—and lead to hair thinning, especially for women.

3. Stress & Telogen Effluvium

Hair loss 2–3 months after major stress is common. It’s called telogen effluvium—and yes, it’s usually temporary. Mind-body practices help break the cycle.

4. Crash Diets & Deficiencies

Iron, protein, and zinc are vital for hair. Fast dieting, skipping meals, or eating too little? Your body may cut off hair nutrients first.

5. Thyroid Imbalance

Thyroid disorders can cause hair to become dry, brittle, or fall out. It’s common in women 30–50. Blood tests can confirm.

🧠 Remember: Hair loss is often a signal, not just a cosmetic issue. Knowing the root cause helps you reclaim control—and your confidence.Support Your Hair Health →
