If you are seeking a surefire way to achieve hair growth, there is one ingredient that has lain unconsidered and overlooked – the humble onion. Inexpensive and readily available, onions can be the end to all of your hair woes. To know the why and how, read on!

Why Is Onion Effective In Facilitating Hair Growth?

Onion has a high concentration of sulfur that helps with numerous hair conditions that cause hair to fall out (1). But first, it is necessary to understand the structure of your hair and the causes of hair fall in order to understand why onion is an effective remedy.

Hair is made up of proteins, out of which keratin gives hair its strength. This is because of the abundance of sulfur present in it. It is the chemical bonds that sulfur forms that determine the texture of your hair, as well as its health (2). In fact, hair loss has been linked to the absence of high sulfur proteins. Methylsulfonylmethane is a highly absorbable source of sulfur, which is found in onions. It helps with the formation of keratin in hair, which results in hair growth (3).

Recent research has shown that the topical application of onion juice can help with alopecia areata (4). Alopecia areata is an auto-immune disease where the body attacks the hair follicles, and these result in spot baldness. Onion juice helps with the re-growth of hair in the spots where the hair has fallen out.


Using onion for your hair can drastically reduce hair fall and help promote hair growth. There are several ways it can be incorporated into your hair care regimen.

Caution: Onion has a strong odor. To remove it, rinse your hair with lemon added to warm water.
