Salt water for hair is a natural beauty treatment that involves using saltwater from the ocean or a saline solution to enhance the health and appearance of hair. It provides the hair with volume, texture, and shine. For example, people who live near the beach may notice that their hair feels thicker and healthier after swimming in the ocean.
Saltwater is rich in minerals such as sodium, magnesium, and potassium, which are beneficial for hair. These minerals help to strengthen hair follicles, promote hair growth, and improve scalp health. Historically, people have used salt water to treat dandruff, scalp irritation, and hair loss.
