Sweat, Sun, and Shed: The Summer Trifecta Killing Your Hair
Summer’s great for your social life, your tan, and maybe even your workout routine, but it can be surprisingly tough on your hair. If you’ve noticed more shedding lately, you’re not alone. Seasonal habits can stress both the scalp and the hair itself, especially for men already dealing with early-stage thinning.
Here’s how summer’s most common routines could be contributing to hair loss.
Sweat
Increased physical activity is great for your body, but all that sweat sitting on your scalp isn’t ideal. It can trap oil, dead skin, and styling product buildup, which may clog follicles and trigger inflammation.
“Exercise is important, but if sweat and product sit too long on the scalp, it creates the kind of environment that can accelerate shedding,” says Dr. Lopresti.
Sun
The scalp often gets overlooked when it comes to sun protection. Prolonged UV exposure can dry out the skin and weaken the protein structure of hair, leading to breakage and increased visibility of thinning areas.
“Especially for men with early hair loss, sun damage to the scalp and hair shaft can make the issue worse,” says Dr. Lopresti.
A 2014 study confirms that UV radiation can degrade essential proteins in the hair, making strands more brittle and prone to damage.
Social Habits
Summer usually means more styling, more late nights, and more dehydration from alcohol. Heavy hair products can build up on the scalp, and dehydration affects overall skin and follicle health , all of which may contribute to increased shedding.
“What you do on weekends matters,” says Dr. Lopresti. “When your scalp isn’t well cared for, even healthy hair can struggle to grow.”
Simple Summer Hair Health Tips
To minimize summer-related hair loss:
- Rinse or shower soon after sweating
- Use a gentle, sulfate-free shampoo
- Avoid heavy styling products or wash them out before bed
- Wear a hat or use scalp-safe sunscreen in direct sunlight
- Stay hydrated throughout the day
