Hair loss is a common concern where in summer can worsen hair fall. Excessive heat, exposure to sun, and dehydration are some of the factors that can make your hair brittle, leading to increased shedding and scalp issues. If you've noticed more hair in your brush during the summer months, you're not alone.

This blog provides information about why hair fall increases in summer, common causes, and what are the effective ways to prevent seasonal hair loss.

Hair Growth and Seasonal Shedding: What’s Normal and What’s Not

Hair growth follows a four-phase cycle:

Anagen (Growth Phase) : Active hair growth.
Catagen (Transition Phase) : Hair follicles shrink.
Telogen (Resting Phase) : Hair stops growing.
Exogen (Shedding Phase) : Hair falls out naturally.

Higher temperatures and increased humidity can push more hair follicles into the shedding phase during summer, causing noticeable hair fall.

Why Does Hair Fall Increase in Summer?

A study published in The British Journal of Dermatology found that hair fall is most common during summer and fall. Reasons include:

Reduced melatonin production due to increased sunlight exposure.
More hair follicles in the shedding phase.
Higher humidity leads to an oily scalp and dandruff.
Increased sweat production causes clogged hair follicles.

Dr Batra’s^® pro tip:

Avoid direct sun exposure; wear a hat or scarf to protect hair from UV damage.

Causes of Hair Loss in Summer

Increased Exposure to Sunlight & Reduced Melatonin
- The scalp gets exposed to direct UV rays, weakening hair follicles.
- Less melatonin production signals the hair to shed more.
Excessive Sweating and Scalp Buildup
- Sweating mixes with dirt and oil, leading to clogged follicles.
- Dandruff and fungal infections increase, accelerating hair fall.
Dehydration and Nutritional Deficiencies
- Lack of hydration makes hair dry and brittle.
- Nutritional imbalances like low iron and protein affect hair growth.
Chlorine & Saltwater Exposure
- Swimming in chlorinated pools strips hair of natural oils.
- Saltwater weakens hair strands, making them more prone to breakage.
Heat Damage from Excessive Sun Exposure
- Hot weather dries out hair, causing frizz and split ends.
- Frequent use of heat-styling tools worsens summer hair loss.

How to Prevent Summer Hair Loss

Keep your scalp clean and hydrated : Wash your hair with a mild shampoo 2-3 times a week.
Use protective hairstyles : Loose braids or buns reduce sun exposure.
Wear a hat or scarf : Shield your hair from direct UV rays.
Drink plenty of water : Aim for 8-10 glasses daily to prevent dehydration.
Eat a hair-friendly diet : Include protein, omega-3, and vitamins for stronger hair.
