Onion juice vs rosemary oil: Which is better for hair massage and hair growth?

If you’ve ever wondered whether onion juice and rosemary oil are more than just kitchen hacks, then you’re not alone. The benefits of using rosemary oil and onion juice for hair growth are more than just folklore. Brimming with antioxidants, nutrients, and sulphur, these two ingredients are used separately for hair growth benefits primarily. Known to strengthen hair follicles, reduce breakage, and support your overall hair growth, let’s see which is better for hair massage, which in turn leads to efficient hair growth.

Onion juice is rich in sulphur, which rebuilds the keratin in hair and further stimulates circulation to nourish the scalp and strengthen hair roots, which eventually reduces shedding. Packed with flavonoids and antioxidants, it fights oxidative stress, supports scalp health, and soothes inflammation. When applied consistently, the compounds present in onion juice revive the dormant follicles and maintain a healthy and supportive hair growth environment.

One does not need fancy tools to create their own onion juice. You just need 2 medium onions, a blender, and a cheesecloth. Peel and chop the onions, blend or grate them into a paste, and strain them using the cheesecloth. Collect the juice in a clean bowl, and then discard the pulp. Your homemade fresh onion juice is ready to use. Massage the juice gently on the scalp for 10-15 minutes before rinsing your hair, and witness the change in a couple of months.

Rosemary oil is a versatile pick derived from the rosemary herb, which has been used for centuries in the kitchen and also for therapeutic and beauty use. Packed with antioxidants and anti-inflammatory properties, it benefits the scalp and strands. Often touted for its ability to stimulate hair follicles and promote healthy hair growth, it starts with improving circulation to the scalp and delivers nutrients and oxygen to the hair follicles. It also reduces hair loss by preventing the breakdown of dihydrotestosterone, which is a hormone responsible for hair thinning and loss.

Wash and dry fresh rosemary leaves, but if you’re using dried rosemary, then there’s no need to wash them. Place it in a clean glass jar and cover it with a carrier oil such as coconut or olive oil. Ensure the herbs are fully submerged with an inch of oil above them. Seal the jar and keep it for 3 weeks in a sunny spot. After the infusion period, strain the oil using a fine strainer and store the oil in a dark glass bottle in a cool place. But if you wish for a faster method, then just simmer the leaves with the carrier oil in a hot pan, and after 30 minutes, strain the oil and store it in your glass jar.

There is no in-between competition, as both are perfect for hair growth. But if you have an oily scalp and need help with sebum production, then go for rosemary oil. People who are suffering from dandruff or are looking for a natural substance to promote overall hair health and prevent hair thinning should consider using rosemary oil in their routine. On the other hand, if you wish to strengthen the root of your hair and want volume, then switch to onion juice. Also, people who are dealing with premature grey hair, you want to stick to onion juice, as it helps in this segment as well.
