I have been using onion juice to treat hair loss for quite a long time now. If you are struggling with the same problem, I genuinely recommend trying it. You will not regret it.

Hair loss is an issue that almost every woman faces at some point in her life. For some, it begins gradually, while for others it happens suddenly and noticeably. No matter how it starts, thinning hair and excessive shedding can deeply affect confidence and emotional well-being. In many cases, women turn to traditional or folk medicine for help, and among the most popular natural remedies are onion juice, aloe vera extract, nettle extract, and several other plant-based solutions.

Thanks to their valuable components and beneficial properties, these natural ingredients help restore damaged hair structure, return lost shine, and make hair softer, smoother, and silkier. Folk medicine has relied on such remedies for centuries, long before modern cosmetic products existed.

Onion in Folk Medicine

In folk medicine, onions have been used not only to address hair-related problems but also to support overall body health. Onion is known for its rich composition of sulfur-containing compounds, vitamins, and natural antibacterial properties. Because of this, it has long been valued as a strengthening and restorative ingredient.

Based on numerous positive reviews from people who have tried various hair loss masks, it can confidently be said that decoctions and masks based on onion extract are among the most effective natural treatments for hair loss. Many people report visible improvements in hair strength, thickness, and growth after consistent use.




Onion juice acts as a natural antibiotic. There have even been cases where onion-based decoctions and masks helped restore hair after chemotherapy. While results can vary from person to person, these examples highlight just how powerful and stimulating this natural ingredient can be for the scalp and hair follicles.

Onion Hair Mask

To prepare an onion hair mask, you will need the following ingredients:

  • Argan oil or burdock oil
  • Honey
  • Onion juice

To begin, pour the onion juice into a small pot. Then add the oil and one tablespoon of melted honey. Mix everything thoroughly until the mixture becomes smooth and well combined. Place the pot over low heat and gently warm the mixture. It should only be heated to room temperature — overheating is not necessary and should be avoided.




This step is important because slightly warm mixtures are absorbed more easily by the scalp and hair roots, allowing the active components to penetrate more effectively.

One important rule to remember is that masks containing onion juice absorb better when applied to unwashed hair. Therefore, washing your hair two days before the procedure is not recommended. Natural scalp oils help the mixture spread evenly and improve absorption.

How to Use the Mask

Using a special brush, apply the mixture directly to the scalp. After application, gently massage it into the scalp using your fingertips. The massage should be soft and careful, as this helps stimulate blood circulation without irritating the skin.

Once applied, wrap your hair with a plastic bag and then cover it with a towel. This creates a warm environment that allows the onion juice to fully saturate the hair and scalp. Leave the mask on for 45 minutes.




After the time has passed, rinse your hair thoroughly with warm water and shampoo. It is important to wash the hair well to remove any remaining residue.

Such masks are recommended to be used several times a week, depending on individual tolerance and scalp sensitivity.

The Only Drawback: Onion Smell

The only downside of this mask is the strong and unpleasant smell of onion. This is often the main reason people hesitate to try onion-based hair treatments.

Fortunately, there is a simple solution. To neutralize the odor, you can add essential oils to the recipe. Suitable options include:

  • Lemon
  • Vanilla
  • Citrus oils
  • Rosemary
  • Lavender

These essential oils help mask the onion scent and leave the hair smelling fresher and more pleasant after washing.




Alternative Option: Onion Paste Mask

Another effective way to treat hair loss is using an onion mask that has a paste-like consistency. This method is slightly different but can be even more effective.

First, finely chop the onion until it becomes very small pieces or a mash. Then mix it with melted honey. After that, add essential oils to improve the aroma. Once the mixture is ready, apply the mask directly to the scalp.

This type of onion mask is recommended to be used twice a week.

This method is considered more effective than masks made only with plant juice, as the onion particles remain in direct contact with the scalp for a longer time. However, it also has some disadvantages.




The first drawback is that small onion pieces are very difficult to comb out of the hair. The second disadvantage, once again, is the strong and persistent onion smell. Despite these inconveniences, many people still prefer this method because of its noticeable results.

Final Thoughts

Hair loss can be emotionally exhausting, but natural remedies like onion juice offer a simple and accessible way to support hair health. While the smell may require some patience, the potential benefits — stronger roots, improved scalp condition, and healthier-looking hair — make this remedy worth trying for many women.




Consistency is key. Like most natural treatments, onion masks do not work overnight. Regular use and proper application are essential to achieving visible results. If used correctly and patiently, this traditional method can become a valuable part of a natural hair care routine.
