    • The most common reason for sweating is working out. When we perform any physically demanding exercise, our body temperature increases. In order to regulate it, we release sweat through all the eccrine glands spread across our body (including the scalp)
    • Temperature is also a big factor behind sweating. Majorly in the summers, we sweat more because the surrounding temperature is high and our body needs to cool naturally
    • Sometimes, even a sleeping posture can trigger sweating as well. If you wonder why does my hair sweat when I sleep, then you need to monitor your postures. When we sleep on one side for a longer duration or cover our hair, then it can increase our body temperature as well
    • Hormones can also have a direct impact on the way we sweat. Some people just sweat more than others. Pregnancy or a drastic lifestyle change can often increase perspiration in our body
    • A medical condition like diabetes or thyroid imbalance can also be a reason behind hair sweating problem. It can also be a side effect of a medicine as well
    • Last, but most importantly – tension, stress and anxiety could be some major triggers for sweating and are certainly not good for our body as a whole.

    • One of the major triggers related to sweat hair loss is lactic acid, which is naturally present in our perspiration. If accumulated on the scalp for a long duration, it can cause inflammation and damage the natural texture of our hair
    • The combination of sweat and sebum on our scalp can also block our hair pores, which can further boost hair loss
    • You must have experienced irritation and itchiness on the scalp after excessive sweating. Needless to say, the more we scratch our scalp, more hair we might end up losing
    • When the amount of perspiration is high through the sweat glands present on the scalp, it leads to their dehydration. This can be a direct effect of sweat on hair
    • The most important factor that answers sweat and hair loss relation, is the presence of DHT. DHT (Dihydrotestosterone) is an active form of testosterone, which is mostly found in post-workout sweat. It has been observed that DHT can bind with our hair follicles and prevent them from growing naturally. This can further contribute to male pattern baldness as well.

    Can Sweat Damage Your Hair?

    • The lactic acid present in our sweat can bind with keratin (protein) that is already present in our hair follicles. This can take away the natural lustre and strength of our hair.
    • If you have a flaky scalp, then the sweat can mix with it and make your scalp moist. This can block your hair follicles from getting the essential nutrients for hair growth.
    • The accumulation of sweat on the scalp can be unhygienic as well. It can get mixed with bacteria on the scalp and might develop into a fungal or bacterial infection.
    • The inflammation on the scalp due to the presence of lactic acid can restrict the supply of blood to the scalp and affect the quality of hair. As lactic acid accumulates on the scalp it also makes the hair brittle and weak
