As healthy as sweating is for your overall body, it isn't for your hair. Sweating helps the body release toxins, as well as increasing circulation but what sweat does to hair is clogged follicles, itchy scalp, and dryness.
Apart from experiencing "dirty" hair, how is sweat bad for hair? Sweat is produced by sweat glands in our skin that are close to the hair follicles in the scalp. When there’s excess sweat on the scalp, it can cause irritation and clog the hair follicles. Clogged follicles can harbour bacteria and fungus, leading to inflammation on the scalp and could possibly affect hair growth.
What if your scalp is already oily? You’re even more at risk for the damaging effects of sweat. Since your scalp is more likely to accumulate sebum, this can mix with sweat and potentially clog your hair follicles.
Sweat also has a high salt content, it can be extremely drying to the hair. Sweat on dyed hair can also make strands more prone to breakage and brittleness.
Protect Hair From Sweat
Dry shampoos aren’t a replacement for washing your hair, but they can help disguise dirt and grease on your scalp, and using it before your workout can help prevent excess sweat from saturating your hair, natural ingredients are better to help absorb the oil and sweat without irritating your scalp.
Apply Leave-In Conditioner
Leave-in conditioners are another great way to reduce the damaging effects of sweat, as they provide a barrier between the hair shaft and sweat, and will also protect the hair shaft from dryness caused by sweating.
Wear A Cotton Headband
Headbands can help absorb sweat at your hairline and prevent it from hitting the rest of your hair. Just be sure to wash it after each use so you get rid of dirt, sweat, and bacteria before you hit the gym again.
