Why Use Onion Juice for Dandruff?

Dandruff is caused by the fungus Malassezia, which is naturally present on the scalp. When your scalp is healthy, it goes unnoticed.

Malassezia feeds on the sebum on your scalp, creating a by-product known as oleic acid. Most people are sensitive to oleic acid, and the scalp reacts to it by breaking out into white flakes and itching. (1)

When you have dandruff on your scalp, the Malassezia population increases by 1.5 to 2 times the average level.

Onions have anti-fungal properties that help treat scalp disorders such as dandruff and keep the skin clean and moisturized. (2)

Onion juice has antimicrobial properties that help control Malassezia‘s activity and relieve dandruff. It helps to quell the non-stop itching sensation that can be exasperating.

Using onion juice on your hair is highly beneficial if you use it regularly. Apart from curing dandruff, onion juice offers many benefits for the hair.
