We can use magnesium for hair growth and maintaining hair health. Today, everyone faces common hair problems and is looking for an easy solution to fight against hair loss and grow longer hair. You can get these by simple foot soak or hair massage. Wondering how? Epsom salt is the solution. It contains magnesium which can also endorse hair growth. This article discusses the role of magnesium in hair growth and ways to use it for getting healthy hair. Read on.

Magnesium And Hair Growth Is There Any Link?

A study conducted in Germany found that magnesium can trigger the hair follicles, resulting in hair growth by more than 50%. The study found out that magnesium is absorbed by the body through the skin by spraying magnesium oil on the scalp and an Epsom salt foot soak (1). Though the sample size and the duration of the study were limited, the results prove that magnesium plays a role in hair growth.

Anecdotal evidence suggests that massaging magnesium oil into your scalp is invigorating. You may experience a pleasant tingling sensation that helps you destress and relax. Apart from combating stress (that can cause hair loss), this stimulation of follicles also boosts blood circulation, thus promoting hair growth. That is why it is widely believed that magnesium is beneficial for hair.

At a cellular level, magnesium is one of the most important nutrients for healthy hair growth. It is an essential cofactor for more than 300 enzymes that regulate multiple biochemical processes (2).

Magnesium is also an essential trace metal that is involved in numerous metabolic functions in the body such as protein synthesis, calcium regulation, and activation of vitamin D (3), (3). Both calcium and vitamin D play an important role in the development of hair follicles (4). Thus, it is involved in the overall growth of your hair.

So, we have learned how magnesium helps promote hair growth. But, what happens when you dont get enough magnesium? Find out below. 

Magnesium Deficiency And Hair Loss

The role of magnesium deficiency in causing hair loss is indirect (5). Since magnesium is involved in multiple metabolic processes, a lack of magnesium can disrupt the mineral homeostasis (mineral balance) (2). This can lead to impaired protein synthesis which, in turn, can trigger hair loss. So, it is recommended to consume magnesium-rich foods such as pumpkin seeds, spinach, almonds, avocado, and rice. (2).

The recommended daily intake of magnesium for adult men and women is 400 mg and 310 mg, respectively (2). This can be met by following a well-balanced diet. You can also get the benefits of magnesium through topical application as it can be absorbed by the skin. Thus, you can massage your scalp with magnesium oil to fight hair loss (1). Magnesium oil is made from a mixture of magnesium chloride flakes and water. You can learn how to prepare it at home.

We have established that magnesium is important for hair growth. Find out in the next section how to use it effectively.
