Benefits of Salt Water for Hair

Sea salt spray is very popular on TikTok, and many people find that it can make their hair curler and appear fuller. So does this trend actually show that salt water is good for hair? The answer is yes, the specific benefits are as follows.

Increase Hair Volume

The high concentration of salt and other minerals in seawater will absorb moisture from the hair, making the hair visually more fluffy after drying, helping to enhance natural curls, in other words, increasing hair volume.

Stimulate Hair Growth

The rich minerals in salt water provide the hair with the nutrients it needs to promote blood circulation in the scalp, thereby delivering more nutrients to the hair follicles. This revitalizes the hair and stimulates hair growth.

Clean Scalp

Salt water acts as a natural exfoliant, helping to remove excess oil, product buildup, and dead skin cells from your scalp. It also reduces dandruff, resulting in a healthier scalp.

Antibacterial and Therapeutic

Salt water has antibacterial properties and can help treat conditions like eczema and psoriasis. It also helps heal cuts and scrapes on the scalp.

Drawbacks of Salt Water for Hair

However, everything has two sides. Although salt water has certain benefits for hair, it should not be overused, otherwise it will have reverse effects.

Hair Dryness and Damage

Prolonged exposure to salt water can strip your hair of its natural oils, causing dryness, frizz, and even breakage.

Impairing the Effectiveness of Hair Treatments

For those whose hair has been dyed or otherwise chemically treated, salt water can cause faster fading and damage the effects of the chemical treatment.

How to Protect Your Hair from Salt Water Damage?

If you often do outdoor sports at the beach and want to relax while protecting your hair, take a look at the tips below. At the same time, this video also gives some tips on protecting your hair after swimming in salt water.

1. Prepare a Suitable Swimming Cap

If you have looser hair, tie it into a braid or bun and wear a swimming cap.

2. Soak Your Hair in Advance

Soak your hair with clean water before getting in the saltwater to prevent your hair from absorbing too much saltwater

3. Rinse Hair After Swimming

I recommend using a sulfate-free shampoo as it is gentler and does not strip away moisture.

4. Lock in Moisture

Hair that absorbs salt water can easily become dry and tangled. Please choose silicone-free conditioners or hair masks to lock in moisture and prevent moisture loss.
