Losing your hair can be a difficult experience and can lead to a lack of self-confidence, negative self-image and even social isolation. So it’s understandable that many people look to solutions to stop hair loss in its tracks, such as hair transplants and preventative treatments to keep their scalp healthy.
One of the biggest buzzes in the hair loss realm is about the use of onion juice to halt and even reverse symptoms, but is it just another folk tale or does it have genuine credentials? In this blog, we’ll give you the rundown on whether applying onion to your scalp can give you healthier hair or whether it’s just kicking up a stink about nothing.
Why Do People Say Onion Juice is Beneficial for Hair?
Onion juice is said to improve the circulation around your hair follicles, which is vital as insufficient blood flow starves your hair of essential nutrients and leaves it at risk of breaking or falling out.
It is mainly down to its Sulphur content – a mineral that our bodies need as part of a healthy diet. The important nutritional element is found in amino acids, which are an essential building block of proteins such as keratin which are needed for growing strong hair.
Onion juice contains antioxidants such as quercetin and flavonoids, which can have benefits such as reducing oxidative stress on the scalp, which is a key factor linked to hair thinning and loss.
Supporters of the onion juice hack claim it can help combat:
- Alopecia Treatment
- Irritated, dry, or itchy scalp
- Hair loss
- Dandruff
- Thinning hair
- Dry or brittle hair
- Scalp infections
Is it Backed Up by Science?
There is limited evidence to back up claims that onion juice is beneficial for hair, and it mainly comes down to a 2014 clinical trial that investigated the ability of onion juice to tackle alopecia areata, a condition that leads to hair loss.
It took 38 patients and put them into two groups - one that applied onion juice to their scalps twice a day for two months and one that used tap water. After six weeks, 20 of the 23 patients in the onion juice group reported hair growth compared to just two of the 15 patients in the tap water group.
Many other people have tried the hack, with mixed results reported in online blogs.
Care must always be taken when following hacks seen online as misinformation can spread unchallenged, and you should always speak to a professional medical expert if you have a health concern.

What Are the Risks of Using Onion Juice on my Hair?
While onions are a natural product and a common part of many people’s diets, it may cause irritation among some people, especially if they are allergic.
Side effects may include scalp irritation, redness and itching.
Certain medications may also increase sensitivity to onion juice, so it’s important to speak to a doctor first.
