While cleansing your face pre- and post-workout is a golden rule for skin, when to wash your hair is less clear cut and it often depends on how much you sweat…
Sweat level: low
You may not need to wash your hair every time – instead, experiment with your workout hair style. For example, for medium to long-length hair, a loose bun or plait will boost volume post-exercise. If you have a shorter style try out different headbands to lessen the amount of sweat reaching your roots.
It may sound simple, but brushing your hair post-exercise can help distribute natural oils especially if you are not washing it and haven’t sweated excessively. Gently brushing through your hair will also help break up sweat or grime that has built up on your scalp.
Sweat level: moderate
Again, you may not need to shampoo after every workout as this can strip hair of nourishing natural oils. Instead try rinsing your scalp between washes, this helps remove sweat build-up (that can weaken hair) but lock-in much needed moisture. For added benefit, massage your scalp whilst rinsing as this can increase circulation at the roots of your hair and help stimulate healthy follicle growth.
Sweat level: high
Excess sweating can dry out your scalp and hair and may lead to breakage. If you sweat a lot or you’re exercising daily, regular shampooing can help control sweat build-up however this can dry hair out and leave it looking dull so limit your use of heat tools such as straighteners to prevent further damage and invest in an intensive conditioner. Using a shampoo with keratin can help enhance your hair’s hydration and strength.
In fact, for all levels of sweat, a hydrating and moisturising conditioner is important to protect your hair from becoming dry and brittle.
