Does excessive sweat cause hair loss?

My scalp sweats a lot, especially after a workout or when it's humid. Sometimes I feel like my hair is thinning. I'm wondering if excessive sweating on the scalp can actually lead to hair loss.

Sweating itself doesn't cause hair to fall out, but letting the sweat dry on your scalp can cause dandruff and itchy fungal infections which weaken the roots. Just make sure to wash your hair with a mild shampoo twice a week and keep the scalp clean.

In our hot weather, sweating is very common. My mother always tells me to wash my hair with cool water if I sweat a lot, to avoid buildup. But if your hair loss is very heavy, it is best to consult a dermatologist rather than just changing your shampoo.

Sweating is just your body cooling down, so don't worry too much. However, if you let salty sweat sit on your scalp for days, it can clog your hair follicles. Try to rinse your hair with plain water after heavy workouts or outdoor work.

Don't stress too much about sweating, yaar! Just pat your scalp dry with a soft towel after coming home and don't tie up wet sweaty hair. Stressing about hair loss will actually make more hair fall out anyway, so stay chill!

I was actually reading about this yesterday. Sweat has lactic acid, which can sometimes weaken the hair shafts if left unwashed for too long. So keeping the scalp clean is definitely key, though it doesn't directly cause baldness.
