Onion For Hair: Benefits And How To Use

Onion is a versatile vegetable and can be found easily in any Indian household. This popular ingredient is fondly used in a variety of Indian preparations and is also believed to help regulate body temperature as well as boost immunity. But did you know that this protean vegetable can also help you grow your hair longer and healthier?

Onions are widely recognized for their healing properties including antibacterial, stimulating, nourishing and cleansing effects. They are also abundantly rich in sulphur. Sulphur is present in every cell of our body with highest concentration in hair, skin and nails. Also known as the ‘beauty mineral’ sulphur helps boost circulation and soothe inflammation. 

They are also rich in vitamins C and B6, calcium, magnesium, potassium, and germanium that help in promoting healthy scalp and make hair stronger, healthier and shinier. 


Onion juice for Hair Growth

Onion juice helps improve blood circulation to the scalp thereby providing proper nutrition to the hair follicles. It is believed to not only soothe the scalp, strengthen the strands but also lead to new hair growth. 

This study tested the effectiveness of onion juice in treating Alopecia areata (patchy, non‐scarring hair loss condition) when applied topically twice a day for a period of 8 weeks. It was observed that regrowth of terminal coarse hairs started after two weeks of treatment with onion juice. At four weeks, hair re‐growth was seen in 17 patients (out of 23 patients) (73.9%), and, at six weeks, the hair re‐growth was observed in 20 patients (86.9%). 


Other benefits of Onion juice on Hair

Apart from hair regrowth, onion juice is also believed to offer the following hair care benefits - 

  • Soothe the scalp
    Onion juice has natural anti-inflammatory properties that help soothe scalp irritations, regulate the scalp and promote a healthy scalp.
  • Dandruff
    Owing to its antimicrobial and antifungal properties, onion juice helps control seasonal dandruff and nicely cleanses the scalp.
  • Calm itchy scalp
    Being a natural anti-inflammatory agent, onion juice also helps provide relief from irritated and itchy scalp.  
  • Reverse graying 
    Onion juice is also believed to help with controlling premature graying. It contains a compound ‘catalase’ that is known to help control the early graying of roots and help restore the natural color of the hair.
  • Revitalize dry hair 
    Onions are rich in flavonoids that act as antioxidants and anti-inflammatory agents. They also play a vital role in nourishing the scalp by enhancing blood flow to the scalp thereby revitalizing dry and damaged hair. 

Ways to use Onion juice on hair

Here is one the easiest ways of using onion juice for hair and you are most likely to have all the ingredients required for this method at home ;)

All you need is an onion. Grate a medium size onion and squeeze out its juice into a clean container. Divide the hair into various sections and start applying the juice directly onto the scalp with the help of a dropper. Massage it in with the tips of your fingers and let it rest for 15 mins or so. Use an organic shampoo to wash it off and let your hair air dry. Use it consistently once or twice a week for best results. 

You can also try one of these DIY recipes to cater to a specific concern- 

  • To soothe itchy scalp 
    Take 2 tsp of olive oil, 3 tsp of coconut oil and 5 tsp of onion juice. Mix well and apply directly to the scalp making different sections. Let it rest for 20 to 30 mins followed by a mild organic shampoo. 
  • To control dandruff 
    Take 1tsp of fenugreek seeds and soak them in 2 tsp of onion juice and water. Grind and make a paste. Apply the paste directly to the scalp. Keep it for 25 to 30 mins and wash it off.
  • To moisturize the scalp 
    Mix 2 tsp of aloe vera gel with 3 tsp of onion juice. Apply onto the scalp and strands. Let it sit for 10 mins and wash it off.
  • To reverse graying 
    Mix 2 tsp Brahmi, Amla and Bhringraj powder with 3 to 4 tsp of onion juice. Apply the paste onto the scalp and let it rest for 30 to 40 mins. Wash off using a mild organic shampoo.

The results using the above methods take time and do vary from individual to individual. We  recommend using them consistently for at least a few months to see noticeable differences. We also highly recommend a patch test for all methods on the hairline or back of the neck prior to using it on the scalp.
