As people approach middle age, many start to worry about hair loss, especially for middle-aged men who are under a lot of stress, the thinning of hair can be quite frustrating. So, is it true that washing hair with saltwater can promote hair growth?
Salt is the most commonly used seasoning in our daily cooking. The main chemical component of salt is sodium chloride (chemical formula NaCl), which accounts for 99% of the salt content. In some areas, potassium chloride is added to reduce the sodium chloride content and lower the incidence of hypertension. In addition, salt in most parts of the world is fortified with iodine to prevent iodine deficiency disorders, and salt with added iodine is called iodized salt.
Saltwater can inhibit sebum secretion, reduce follicle damage, and also has bactericidal and disinfectant effects. Therefore, washing hair with saltwater can effectively treat seborrheic hair loss.
Washing hair with saltwater can also suppress the production of dandruff, as dandruff is often caused by fungal infections. When washing hair, a proper amount of salt can act as a bactericide and achieve an anti-dandruff effect.
In addition, saltwater has better cleaning power than plain water, and even better than some shampoos. Occasionally washing hair with saltwater can have a good cleaning effect.
However, it is important to note that saltwater can be irritating to the scalp and should not be used too frequently. Otherwise, it may lead to imbalanced sebum secretion, resulting in dry and dull hair, and excessive dandruff. Generally, washing hair with saltwater for 5 minutes each time, twice a week is sufficient. After washing hair with saltwater, if combined with scalp massage, it can achieve better results.
