Swimming in the sea is not really damaging to the hair in itself, although excessive sunshine and salt can damage the hair.
When people swim in the sea, it is generally in the summer, and in sunny weather. Although the sunshine can make us feel very cheerful, there is also a hidden danger in ultraviolet light. The reason for this danger is that ultraviolet light is very high energy, and so it can damage things that it comes into contact with, including hair. This is not actually dangerous, as hair is "dead", however the damage caused can make your hair appear quite dull and lifeless.
There are some conditioners available nowadays that you can put into your hair before swimming that will protect it from damage and drying out.
Salt, which is in the sea, is not thought to be good for the hair, so it is important to wash the salt out of your hair after you have been in the sea.
Generally speaking, a few swims in the sea will not cause particular damage to your hair.
