How to Use Onion Hair Oil for Hair Growth – A Complete Guide

by Mamta Yadav 28 Aug 2025

Many people wonder how to use onion hair oil for hair growth when seeking natural ways to get thicker, healthier hair. Onion oil is rich in sulfur, antioxidants, and essential nutrients that help reduce hair fall, combat dandruff, and promote faster growth. Knowing when to apply onion oil on hair and the best time to use onion hair oil ensures you get maximum benefits.

Benefits of Using Onion Hair Oil

  • Promotes Hair Growth: Onion oil deeply nourishes the scalp, enhances blood circulation, and activates dormant follicles, encouraging new hair growth.
  • Reduces Hair Fall:  The sulfur content in onion oil helps in strengthening the hair roots, reducing breakage and hair thinning.
  • Controls Dandruff: One of the most significant benefits of using onion oil for dandruff and hair fall is its antibacterial and antifungal properties, which help keep the scalp clean and flake-free.
  • Adds Shine and Strength:  Regular application helps improve hair texture, adding shine and making it soft, smooth, and more manageable.

When to Apply Onion Oil on Hair?

Many people wonder when to apply onion oil on hair for maximum results. Ideally, onion oil should be applied:

  • At Night – Applying onion oil at night and leaving it overnight allows the nutrients to penetrate deeply into the scalp.
  • 2-3 Hours Before Shampoo – If leaving it overnight is not possible, apply the oil at least 2-3 hours before washing your hair.
  • 2-3 Times a Week – Consistent use of onion oil is key to achieving visible results in reducing hair fall and promoting growth.

Best Time to Use Onion Hair Oil

The best time to use onion hair oil depends on your routine, but evenings or nights are preferred for deeper nourishment. Applying it before bedtime helps in better absorption and allows the oil to work overnight to strengthen the roots and promote hair growth.

How to Use Onion Hair Oil for Hair Growth – Step by Step

  • Detangle First: Carefully comb your hair with a wide-tooth comb to remove tangles and reduce damage before applying oil.
  • Warm the Oil Slightly: Heat the oil until lukewarm to help it penetrate better and stimulate scalp circulation.
  • Divide into Sections: Part your hair into small sections so the oil can be applied evenly from roots to ends.
  • Massage Gently: Apply a few drops of onion oil and massage your scalp in soft circular motions for 5–10 minutes to improve blood flow and nourish follicles.
  • Allow It to Work: Leave the oil on for at least two hours or overnight for maximum nourishment.
  • Wash and Condition: Rinse thoroughly with a mild, sulfate-free shampoo and follow with a conditioner for smooth, soft hair.

Onion Oil for Dandruff and Hair Fall – How It Helps

  • Antifungal Action – Onion oil prevents fungal infections and scalp irritation, which are common causes of dandruff.
  • Strengthens Hair Follicles – The sulfur content reduces breakage, thereby controlling hair fall.
  • Balances Scalp Health – Regular use keeps the scalp nourished, preventing dryness and itchiness.

Tips for Using Onion Hair Oil Effectively

  • Mix onion oil with coconut or olive oil to reduce its pungent smell and enhance nourishment.
  • Use fresh onion juice with oil for a DIY hair mask once a week for added benefits.
  • Avoid using onion oil on a wounded or sensitive scalp.
  • Be consistent – hair growth results may take 6-8 weeks of regular use.
