Is sea water good for oily hair?

At the blog de Hospital Capilar, a clinic specialized in hair grafting in Madrid, Murcia and Pontevedra, we tell you everything you need to know about whether seawater is good for oily hair.

How does seawater affect oily hair?

When we swim at the beach it is common to notice that the hair, especially its texture, changes. This is due to the large amounts of salt and iodine contained in the sea which, when in contact with the scalp, interfere with its normal functioning.

The sea has multiple properties for the hair and the most outstanding is its power to reduce sebum on the scalp. Therefore, yes we can say that sea water is good for oily hair as it decreases sebum levels. In cases where you have oily and fine hair, seawater is also beneficial as it adds volume. This is mainly due to the iodine that the sea contains.

However, in no case can we resort to sea water as a treatment for oily hair, since an excess of salt and iodine can have negative effects, especially on the texture of the hair by drying it out.
