Sweating from your scalp helps unclog your hair follicles, allowing room for new hair to grow. It also opens up the pores on your scalp, releasing any build-up inside your pores that could be stunting the growth of your hair.
But when there’s excessive sweat, specially on your your scalp, that isn’t great for your hair.
According to doctors, excessive perspiration can damage your hair health and change your hair texture. When you sweat a lot, the sweat (water and natural salts) builds-up on your scalp and may clog the hair follicles. As a result, it creates an unpleasant environment for hair growth, which leads to hair loss.
How to stop sweat from damaging your hair?
1- Apple Cider Vinegar
Apple cider vinegar is known to control sweat. Mix a couple of table spoons with warm water, massage the mixture in to your scalp and leave it on for a couple of minutes before rinsing it off.
2- Essential Oils
Massaging your scalp with essential oils ca soothe it and reduce hair fall. Experts recommend Cedarwood essential oils to diminish hair loss. Lavender oil has anti-microbial and anti-bacterial properties that help to keep your scalp healthy. Camomile oil helps add shine and softness to it.
3- Brush Your Hair
Brush or comb your hair after exercise when still wet from sweat as this will distribute the oils and sweat along the hair minimising the concentration on your scalp.
4- Dry Shampoo
Dry Shampoo before the workout will prevent excess sweat from gathering in your hair. A dry shampoo using natural ingredients like starch, rich flour and cocoa will help.
5- Leave-in Conditioner
Leave-in conditioner is an excellent way of reducing the effect of sweating on hair as it provides a protective layer between the sweat and the hair shaft. In case the workout produces dryness, this is an excellent solution for that too.
