Onion extract is a good source of sulfur, which is an essential mineral that helps to promote healthy hair growth. Sulfur is a component of keratin, which is a protein that makes up our hair. Keratin gives our hair strength and elasticity, and sulfur helps to form the bonds that keep the keratin molecules together.
In addition to its sulfur content, onion extract contains antioxidants that can help to reduce inflammation and promote circulation in the scalp. This can help to nourish the hair follicles and promote healthy hair growth.
Studies have shown that onion extract can be effective in promoting hair growth and improving hair thickness. A study published in the Journal of Dermatology found that using a hair tonic containing onion extract for four weeks led to a significant increase in hair growth and improved hair thickness in people with alopecia areata, a type of hair loss condition.
Another study published in the Journal of Korean Medical Science found that using a shampoo containing onion extract for six weeks led to a significant increase in hair growth and improved scalp condition in people with hair loss.
Overall, onion extract can be a good source for hair health and growth due to its sulfur content and antioxidant properties. Incorporating onion extract into your hair care routine may help to promote healthy hair growth and improve the overall condition of your hair.
