Does Body Heat Cause Hair Loss?

Yes, excessive body heat can contribute to hair loss by dehydrating hair follicles, weakening roots, and increasing scalp inflammation. While normal body temperature doesn’t cause hair fall, persistent internal heat or external heat exposure can damage the scalp, encourage fungal growth, and trigger shedding.

According to Dr Harikiran Chekuri,

Body heat is not a primary cause of baldness, but when combined with factors like hormonal imbalance, poor scalp hygiene, stress, or nutritional deficiencies, it can accelerate hair thinning and shedding.

Excessive body heat can disturb the scalp’s natural balance and weaken hair follicles over time. When heat is not regulated, it directly impacts scalp health, hydration, and hair strength, leading to increased hair fall.

• Moisture Loss: Excess body heat dries out the scalp and hair follicles, making hair brittle and more prone to breakage.
• Scalp Damage: Heat combined with sweat can trigger dandruff, fungal infections, and seborrheic dermatitis, weakening hair follicles over time.
• Dehydration: Excessive sweating may lead to dehydration, reducing the supply of essential nutrients required for healthy hair growth.
• Heat Styling Damage: Frequent use of straighteners, curlers, or blow dryers can cause permanent damage to the hair shaft, resulting in thinning and breakage.

Since nutritional deficiencies can worsen heat-related hair loss, addressing internal health is essential. Read more in our guide on Can Vitamin B12 Reverse Hair Loss?

Excessive heat can weaken hair roots and affect scalp health, but simple daily habits can help reduce its impact and prevent heat-related hair loss.

• Stay Well Hydrated: Drinking enough water throughout the day helps regulate body temperature and keeps hair follicles hydrated, reducing dryness, breakage, and heat-related shedding.
• Maintain Proper Scalp Hygiene: Washing the scalp regularly removes sweat, oil, and dirt buildup, lowering the risk of fungal infections and inflammation that can worsen hair fall.
• Reduce Heat Styling Exposure: Frequent use of dryers, straighteners, or curlers weakens the hair shaft. Limiting heat tools and using a heat protectant helps prevent damage and breakage.
• Control Diet and Internal Body Heat: Avoid excessive junk, oily, and spicy foods, as they can increase internal body heat and scalp oiliness, contributing to hair weakening and hair loss.
