Onion – the natural hair growth stimulant
It’s not a coincidence that onion juice is recommended by a myriad of beauty bloggers, dermatologists, and even the ancient Indian medical system of Ayurveda for hair loss and weak hair. The reason lies in its composition:
– Organic sulfur: Supports collagen production, which is essential for hair follicle development.
– Quercetin and flavonoids: Powerful antioxidants that protect hair from free radicals and reduce scalp inflammation.
– Antibacterial and antifungal properties: Cleanse the scalp, treat dandruff, and strengthen the hair roots, reducing hair fall.
A small study published in the Journal of Dermatology found that over 70% of participants who applied onion juice twice a week for six weeks experienced significant hair regrowth in bald or thinning areas.

Using onion for hair care at home
1. Onion juice hair mask
Ingredients:
1 red onion
1 tablespoon of coconut oil (or castor oil)
Instructions:
Peel and juice the onion, or blend and strain it.
Mix with the oil to reduce the strong onion scent and enhance hair nourishment.
Apply to the scalp and gently massage for 5–10 minutes, then leave it on for an additional 20–30 minutes.
Rinse with a mild, fragrant shampoo.
Repeat this process 2–3 times a week. After 3–4 weeks, you should notice an increase in hair growth and stronger roots.
2. Onion and rose water hair spray
This is a milder version for those sensitive to the strong onion scent:
Mix equal parts onion juice and rose water (1:1 ratio).
Pour the mixture into a spray bottle and store it in the refrigerator for up to 3–4 days.
Spray it onto your scalp every night and let it dry naturally, without rinsing.
Tips for faster and healthier hair growth:
– Indian scalp massage: Use your fingertips to gently massage your scalp in a circular motion, moving from the front to the back of your neck. This improves blood circulation and nourishes the hair follicles.
– Nutritional support: Increase your intake of biotin-rich foods like eggs, salmon, and avocados, as well as vitamins B, C, and E. Also, ensure you’re drinking enough water daily.
– Proper hair washing techniques: Avoid vigorous scalp scratching, extremely hot water, and excessive heat styling.
Important considerations when using onion for hair care
– Do not apply onion juice to an open wound or severely inflamed scalp.
– Always perform a patch test on a small area of your skin before using it for the first time.
– Onion has a strong scent, so it’s best to use it in the evening when you don’t plan to go out.
– Avoid leaving onion juice on your hair for more than an hour, as it may cause scalp dryness.
Eliminating onion scent from hair after application – No more unpleasant odors
While onion is highly effective in promoting hair growth, its distinctive odor can be off-putting to some. However, with these simple tips, you can effectively eliminate the onion scent from your hair:
1. Rinse thoroughly with a strongly scented shampoo
Opt for a natural shampoo infused with essential oils like lemongrass, mint, grapefruit, or lavender.
Shampoo twice, massaging your scalp for 2–3 minutes each time to ensure the onion scent is completely removed.
Pro tip: Use warm water for the first wash to eliminate the onion and oil, then rinse with cool water to seal in the fragrant scent.
2. Neutralize the scent with natural hair rinses
After shampooing, try one of the following rinses:
Diluted apple cider vinegar (1 tablespoon per 250ml of water): This mixture smooths the hair cuticle and effectively eliminates odors.
Diluted lemon juice: Enhances hair shine and neutralizes onion scent.
Overnight rice water: Nourishes the hair while eliminating odors.
Pour the chosen mixture slowly over your hair after shampooing, let it sit for 3–5 minutes, and then rinse with clean water.
3. Apply essential oils to your hair after blow-drying
Once your hair is dry, apply 1–2 drops of grapefruit, rosemary, jasmine, or vanilla essential oil to the ends of your hair, avoiding the scalp to prevent oiliness. Your hair will smell subtly sweet and pleasant all day!
