The Water Effect
When you think of getting your hair wet, showering and swimming come to mind. But our hair also absorbs water when we exercise (through sweat), when we visit the sauna, hammam or spa (thanks to the steam) and, of course, when we get caught in a rainstorm and forget our umbrella! So what effect does this have on its wellbeing?
For one thing the hair shaft is permeable, which means it absorbs moisture and when it does it “swells”. In this moisture-laden state, our hair becomes more sensitive.
Add to this the fact that seawater and sweat contain their fair share of salt, which has a tendency to dry out the hair shaft. Chlorine, meanwhile, contains a mixture of chemicals and can be even harsher on your hair, not to mention the changes in color it can provoke on blonde hair. Excessive sweating takes the potential damage one step further, as in the long term it can lead to hair loss, but this is less frequent.
