Onions have been used for centuries for their medicinal properties and health benefits. One of the most well-known benefits of onions is their ability to promote hair growth. In this blog post, we will explore the science behind onion's effectiveness in promoting hair growth and the different ways to use onions for hair growth.
What makes onions effective for hair growth?

Onions contain a high amount of sulfur, which is a vital component of keratin, the protein that makes up our hair, skin, and nails. Sulfur is known to strengthen hair follicles, reduce hair breakage, and promote hair growth.
