If you want to nourish your hair from within, you must turn to nature to pamper your tresses with pure and clean ingredients. Onion juice and curry leaves are great examples of such ingredients that can give your hair a complete makeover.
Curry leaves from the curry plant (Murraya koenigii) have been known for their culinary use and recently for their medicinal use. Curry leaves have been studied and used to treat diseases such as diabetes, cancer, and heart disease.
In some studies, the consumption of curry leaves was shown to normalize cholesterol levels and improve glycemic status in people. There are also studies revealing that curry leaves protect the body against oxidative stress, which is the reason behind many disorders. (1)
Onions are present in almost every home and are used to treat a variety of disorders. They contain an antioxidant enzyme called catalase, which helps retain the hair’s natural color.
A deficiency in catalase can lead to premature graying of hair. When hair becomes prematurely gray, it becomes weak and tends to break, causing hair loss. This hair problem can be avoided after regular use of onion juice as it provides catalase to the hair follicles. (2)
Why to Use Onion Juice and Curry Leaves for Hair?
Curry leaves have been used by people in India, Sri Lanka, and other South Asian countries to improve hair growth and quality.
Research has also confirmed that boiling fresh curry leaves with coconut oil until it is reduced to a black residue produces a herbal hair tonic that works wonders to retain normal hair tone and improve hair growth. (3)
Onion juice has proven its ability in improving hair regrowth and quality because it is rich in sulfur, stimulating inactive hair follicles and promoting hair growth. Sulfur is needed to form the hair-building protein keratin, which strengthens the hair and improves its elasticity.
Mixing 2 tablespoons of onion juice and 2 tablespoons of coconut oil and applying the mixture to the hair scalp has been shown helpful in hair regrowth. (2)

Benefits of Curry Leaves for the Hair
Curry leaves provide the following effects when used on the scalp and hair:
1. Helps control hair loss
It is natural for a person to lose up to 100 strands of hair a day as it is part of the body’s regeneration process. However, if you are losing more than a hundred strands a day, it should ring an alarm, and you should take steps to stop it.
That’s where our “hero” ingredient, curry leaves, can help out.

2. Strengthens the hair shaft
Curry leaves are rich in flavonoids, vitamins, terpenoids, and nicotinic acid, among other beneficial compounds, which are needed for hair growth and controlling hair loss.
The vitamin B and beta-carotene in curry leaves help improve the hair shaft’s quality and make the hair healthy and shiny. (3)
Regularly applying curry leaves and coconut oil or onion juice can help strengthen the hair fibers.
3. Prevents premature graying of hair
When your hair turns gray due to aging or genetics, the natural pigment of the hair is lost forever and can’t be restored. However, if your hair has grown gray due to pollution, chronic diseases, smoking, or a stressful event in your life, it is possible to reverse it by using natural ingredients such as curry leaves.
The dark color in your hair is due to melanin, and during oxidative stress, the amount of melanin reduces, leading to silvery or white hair.
Curry leaves promote the natural production of melanin in the hair as it works against oxidative stress and prevents premature graying of the hair. (4)
