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. 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.
