Is onion juice effective for washing hair?

Onion is a good thing, because onion has very high nutritional value, which can promote people's health. Onion is rich in nutrients, which can supplement the body's needs and has a great effect on improving the body's resistance. Many people also use onions to make things other than food. For example, washing hair with onions is a common practice. Let's take a look at the effect of washing hair with onion juice?

Onion is a very special food. It is the only known vegetable that contains prostaglandin A. Prostaglandin A is a natural vasodilator that can dilate blood vessels, reduce blood viscosity, and promote blood microcirculation. Therefore, onion is a longevity vegetable. Eating it regularly can greatly reduce the possibility of thrombosis and high blood lipids. In addition, onions contain strong plant bactericides with strong bactericidal ability, and have excellent effects both internally and externally!

1. Rub onion juice directly on your scalp

This method is somewhat similar to rubbing the scalp with ginger, both of which can stimulate hair follicles to grow. The benefits of onions are actually more obvious than those of ginger, because science has proven that prostaglandin A in onions can dilate blood vessels and improve blood circulation. Its effect on hair is undoubtedly equivalent to strengthening the nutrition of hair follicles and stimulating hair growth, which is similar to the effect of minoxidil.

2. Wash your hair with onion juice

This is an old folk remedy. Wrap a mashed onion with clean sterilized gauze, then rub it gently and repeatedly on your scalp to allow the onion juice to fully penetrate it. Finally, wash it off with warm water. It can relieve itching and dandruff, and also has the effect of promoting hair growth. Because onions contain sulfides, flavonoids and other ingredients, they have significant bactericidal effects. Onions also contain nutrients such as carotene, vitamin B1, vitamin B2, vitamin C, vitamin E, etc., which nourish scalp cells.

However, it should be noted that some people are allergic to the irritation of onions, so this method should not be used in this case.
