Regrow hair naturally: The secret ingredient is already in your kitchen

Did you know a vegetable with a pungent smell could be your way to unlock hair regrowth. Science suggests onion juice could be a powerful ally in reviving hair growth. From age-old home remedies to modern research findings, the buzz around onion juice for hair health is strong. Here we explore the scientific evidence, its mechanism and practical considerations to use onion juice for hair growth.

A pivotal study published in the Journal of Dermatology in 2002 investigated the effects of crude onion juice on individuals with alopecia areata, a type of autoimmune-induced hair loss. The study involved 38 participants who applied onion juice to their scalps twice daily for two months. Results indicated that 87% of participants experienced hair regrowth, with men showing a higher response rate than women.
Researchers attributed this regrowth to the high sulfur content in onion juice, which helps boost collagen production and improve blood circulation to hair follicles. But how does the mechanism actually work?

The secret behind onion juice’s ability to promote hair regrowth lies in its unique nutritional and biochemical properties. Onions are packed with compounds that directly support scalp health and hair follicle function.
Sulfur boost keratin production
​Sulfur, a key component of onion juice, studies suggest it is an essential for the formation of the structural protein that makes up hair- keratin. When applied to the scalp, sulfur helps nourish hair follicles, strengthen hair shafts, and reduce breakage.
Antibacterial properties fight scalp infections
Onions have strong antibacterial and antifungal properties, which help combat scalp infections that can contribute to hair loss or hinder new growth.

From preparation to application, incorporating onion juice to regrow hair isn’t very difficult and can be easily done at home.
How to use: Peel and chop 2 to 3 medium sized onions
Blend the onions to create a smooth paste Strain the paste to extract the onion juice Apply the juice directly to the scalpFocusing on areas with hair thinning or lossMassage gently to stimulate circulationLeave the juice on the scalp for 30 to 60 minutesRinse thoroughly with water and shampoo.

The proven benefits of onion juice for hair growth come with a set of drawbacks as well. The very first problem is the strong pungent smell that can linger even after rinsing the scalp with loads of shampoo. Some other problems may include eye irritation and burning sensation.

It is important to note that applying onion juice on the scalp will not provide immediate results. The difference will become visible after gradual application, which may take weeks or months.
What also matters is maintaining a healthy diet full of nutrients, keeping the scalp clean and healthy, practicing gentle hair-care, avoiding excess heat and styling and more.
