Swimming in the ocean provides a number of benefits to your physical and mental well-being. But for your hair, the activity can be a double-edged sword, because the effect of seawater highly depends on your hair type and the current condition of your strands.
/wp:paragraph wp:paragraphCosmetic manufacturers sell us beachy waves in a bottled form during wintertime, but with summer holidays upon us – we can get the real deal out on the actual beach.
/wp:paragraph wp:paragraphThe impact of salt in sea water is not black & white though. There are some benefits from the exposure to seawater for hair, but in order to protect from its negative effects: namely dryness and brittleness, there are a few precautions you can take.

Saltwater in hair creates beachy waves
/wp:heading wp:paragraphSea water, aside from the actual water, contains chloride, sodium, magnesium, sulphate, calcium, and other elements. Your hair is comprised of keratinous protein with cross links that hold that protein making the shape which is effectively – your hair.
/wp:paragraph wp:paragraphThe cross-links are three-dimensional binds formed by covalent bonds between adjacent amino acids (proteins). In turn, salt – or sodium chloride and magnesium sulphate (both elements present in the seawater) create extra cross-links within your hair strand, which curls and curves it, thus putting the “waves” in your beach waves.

Now that we’ve got the mechanics of your beauty waves out of the way, let’s see how salt water affects hair:
/wp:paragraph wp:heading {"level":3}Con: Dehydration of hair
/wp:heading wp:paragraphThe salt in general, including sea water, is hygroscopic: i.e. it attracts more water to your hair and forms salt crystals. Those salt crystals may give your hair extra body, but this process also wicks away the moisture from the inside of your hair strand – making it dry and brittle. This process also reduces the crosslinks between cysteine bonds in your strands making it more fragile, hence proving saltwater damages hair.
/wp:paragraph wp:heading {"level":3}Con: Extreme dryness for chemically treated hair
/wp:heading wp:paragraphIf you are using dye or bleach, or if your hair structure has been chemically altered – the sea water can worsen your hair condition. Chemical treatment already strips your hair from nutrients and artificially changes the cross-links within your hair strands. The hygroscopic properties of salt water take away moisture as described above – even from healthy hair, but it gets even worse for chemically altered strands, making it extra brittle.
/wp:paragraph wp:heading {"level":3}Pro: Extra body and fullness of hair
/wp:heading wp:paragraphOn the plus side, salt water crystals add the “body” to your hair. This can be a good thing if you want to increase your hair volume. Beware, as this extra salt also makes them dry and lifts up the hair cuticle, which makes it susceptible to further moisture loss.
/wp:paragraph wp:heading {"level":3}Pro: Nutrients absorbed by your scalp
/wp:heading wp:paragraphSea water is good for your hair because it contains nutrients that your body needs. For example, magnesium has been known to strengthen your nervous system and have a calming effect on your body. Magnesium is also absorbed well through your skin, making an ocean dip not only enjoyable but also – healthy for your nerves. Less stress has been linked to better hair growth, so the calming effect of magnesium is a big plus for your hair.

Pro: Exfoliation and blood flow stimulant
/wp:heading wp:paragraphThe salt water crystals can serve as an excellent exfoliator for your scalp which can help remove product build up from your scalp and hair roots. It can also stimulate blood flow to the scalp if you massage your scalp with a salt scrub. So massaging your scalp after the hair dries – is a good idea, as there are numerous benefits in stimulating blood flow in the scalp.

/wp:paragraph wp:heading {"level":3}Pro: Antifungal properties
/wp:heading wp:paragraphSalt can help against the dandruff originated from a fungus, as salt water has antifungal properties. Those anti-fungal properties occur by fungi having to spend more energy in achieving osmosis (or osmoregulation) with salt water vs fresh water, instead of spending that energy on its own growth.
/wp:paragraph wp:heading {"level":3}Pro: Natural shampoo and grease remover
/wp:heading wp:paragraphIf you have a greasy scalp, then sea water can help you to strip heavy oils and extra sebum, acting as a dry shampoo. It absorbs excess oils present on your tresses close to its root and may help you wash your hair less frequently as a result. Mind that frequent hair washing can be very damaging to your hair, read more on this here.
/wp:paragraph wp:headingDoes Salt Water Damage Hair: Verdict
/wp:heading wp:paragraphThe answer is therefore, two fold. To prevent your hair from drying as a result of exposure to the sea and ocean water – consider using natural hair oil or biodegradable and ecologically-friendly leave-in conditioner prior to walking onto the beach. This will coat your hair strands and prevent salt from wicking away the moisture.
