Is It Safe To Use Epsom Salt For Hair?

Yes, it is safe to use Epsom salt for your hair and scalp. It is a naturally occurring chemical compound made of magnesium, sulfur, and oxygen. Epsom salt is also known as magnesium sulfate.

According to the Cosmetic Ingredient Review (CIR) expert panel, Epsom salt or magnesium sulfate does not have any toxicity concerns. They concluded that accidental inhalation of Epsom salt in the form of sprays and topical application on skin and hair does not cause any adverse health hazard and is non-irritating (1).

Epsom salt is very different from regular table salts and sea salts as it has a different chemical structure. It is termed “salt” because of its texture and salt-like appearance. It is traditionally used to manage sprains, muscle pain, insomnia, and fibromyalgia. While none of its benefits are scientifically studied, anecdotal evidence claims that Epsom salt is beneficial in addressing these ailments.

Epsom salt is widely used as a hair volumizer and hair and scalp spray. The possible reason is that Epsom salt removes oil from the hair and scalp, reducing greasiness. Salt sprays also impart texture to the hair, adding natural waves and giving the strands a slightly crunchy texture.

Anecdotal evidence claims that Epsom salt sprays may also help curb dandruff. Dandruff is caused by Malassezia, a yeast-like fungus that feeds on the sebum and lipids on your scalp. Epsom salt may reduce the excess grease, managing the proliferation of the fungus. That is one possible explanation for why it may work, although there is no scientific data to support this claim.
