Swimming in a chlorinated pool is a popular summer activity, but it can be damaging to your hair. Chlorine is a harsh chemical that can strip away your hair's natural oils, leaving it dry, brittle, and prone to breakage. It can also cause your hair color to fade, especially if you have dyed hair.
The extent to which chlorine damages your hair depends on a number of factors, including the frequency and duration of your swims, the concentration of chlorine in the pool, and the condition of your hair. If you have dry or damaged hair, it is more likely to be affected by chlorine. Similarly, if you swim frequently in a heavily chlorinated pool, your hair is more likely to be damaged.
