Tea tree oil is known for its thin consistency, as it does not clog the hair follicles and improves scalp health. However, it should be diluted with a carrier oil and can also be added to your shampoo or serum or used as a spray. Tea tree oil has antifungal and antibacterial properties that help fight dandruff, scalp acne, and other infections, which further create a healthy environment for hair growth, even in winter.

Argan oil promotes hair growth by nourishing the scalp and helps in strengthening the strands, preventing breakage. Brimming with vitamin E, fatty acids, and antioxidants, it has antioxidants that provide moisture to hair and scalp. From strengthening hair follicles to protecting the strands and scalp against damage, it creates a healthier environment for new hair growth. This helps to give your hair a fuller appearance and allows it to grow longer.

This is a lesser-known pick for hair growth, as pumpkin seed oil benefits hair growth by nourishing the hair follicles with essential fatty acids and antioxidants and improving the overall scalp health in its own ways. It blocks DHT, which is a hormone linked to hair loss, and reduces inflammation as well. Better for consistent use, pumpkin seed oil improves hair thickness, strength, and shine, giving you healthier and more resilient-looking locks.

Derived from the leaves of the rosemary plant, its medicinal properties help in promoting hair growth and maintaining scalp health. It stimulates the scalp and improves overall circulation, which promotes hair regrowth. Rosemary oil also prevents hair thinning and shedding and soothes an irritated scalp, which promotes the growth of new follicles. From treating dandruff to an itchy scalp, this oil can easily be used throughout the year and can be blended with a carrier oil.

Peppermint oil is known for its cooling and tingling effect when it is applied to the scalp. This oil is traditionally known for its soothing properties and also promotes hair growth. The menthol in peppermint oil improves blood circulation to the scalp, stimulating the hair follicles, which further encourages hair growth. It also reduces scalp inflammation, reduces dandruff, and creates a healthy environment for hair to grow. From keeping bacteria away, which again impedes the hair growth process, it blesses you with long, strong, and clean scalp haircare.

Herbal hair oils are often considered the best for hair growth because they combine natural, nutrient-rich ingredients that nourish the scalp, strengthen hair roots, and improve overall hair health without harsh chemicals. Infused with herbs like bhringraj, amla, fenugreek, and neem, these oils boost blood circulation to the scalp, reduce hair fall, prevent dandruff, and stimulate the follicles for faster, healthier growth. Their antioxidant and anti-inflammatory properties also help soothe scalp irritation, making them a gentle yet powerful solution for long-term hair growth and thickness.

Lavender oil has shown promising effects in promoting hair growth, supported by both animal and human studies. In lab research, topical application of lavender oil increased hair follicle number and depth, thickened the dermis, and accelerated hair growth in mice. More recently, a 2025 human clinical trial testing a blend of rosemary and lavender oils found significant improvements in hair density, thickness, and growth rate over 90 days, while reducing hair fall compared to a placebo. These benefits are attributed to lavender’s anti-inflammatory, antimicrobial, and scalp-soothing properties, which create a healthier environment for hair follicles and may support natural hair growth.
