Neem, scientifically known as Azadirachta indica, is a tree native to the Indian subcontinent. It has a rich history and has been highly regarded in traditional Ayurvedic medicine for centuries, featuring prominently in ancient Indian texts dating back thousands of years. The earliest documented mention of neem is in ancient Tamil texts such as the Thirumular Thirumantiram-Ennayiram, Tholkappiam and the ancient Tamil works of Sangam literature 1. Neem continued to be revered in Indian culture and has been highlighted in the classical Ayurvedic texts of Caraka Samhita and Susruta Samhita. Referred to in Indian folklore as the “village pharmacy” due to its diverse medicinal properties, neem oil has a wide range of therapeutic applications that we are still exploring today.
Neem Oil For Skin
- Insect repellent
Neem oil has insecticidal properties that can help repel mosquitoes, flies, ticks, fleas and other pests that can bite or irritate the skin. Research suggests that neem has natural insecticidal properties, making it a natural pest control treatment that can also work to prevent bites when applied over the skin 2. This is why many Ayurvedic skin creams that contain neem oil also work as insect repellents.
- Scabies
A parasitic infection that is common in babies and children, scabies are tiny mites that can infest the skin, causing intense itching and inflammation. These symptoms appear as the mites burrow into skin and lay their eggs. Studies have found that neem oil and other neem extracts may fight scabies infestations and provide relief 3.
- Psoriasis & Eczema
Neem oil can help relieve the symptoms of eczema and psoriasis, which are chronic inflammatory skin conditions that cause dryness, itching, scaling, redness, and cracking of the skin 4. Neem oil can help moisturize, soothe, and repair the damaged skin barrier, as well as reduce inflammation and infection.
- Ringworm
Neem oil has antifungal properties that can help treat various fungal infections of the skin, such as ringworm, athlete’s foot, jock itch and nail fungus 5. It works by disrupting the cell membrane and growth of the fungi, as well as enhancing the immune system’s ability to fight off the infection
- Anti-aging effects
Neem oil can help fight the signs of aging by stimulating the production of collagen and elastin, which are proteins that give the skin its structure and elasticity. Collagen and elastin levels decrease as we age, leading to sagging, wrinkling, and thinning of the skin. Neem oil application was found to not only boost collagen and elastin production, but it also increased protection against UVB radiation 6.
- Wound Healing
The use of neem oil for skin damage can help speed up the healing process of cuts, scrapes, burns, or insect bites by promoting blood circulation and tissue regeneration 7. It also has antiseptic and analgesic properties that can prevent infection and relieve pain. Neem oil can also reduce scarring by preventing excessive formation of collagen at the wound site
- Skin Toxicity
Neem oil application may also be helpful for treating exposure to toxins as there is evidence showing that gels containing neem oil could even reduce toxicity from radiation therapy in cancer patients 8. Although this was a small study involving just 28 subjects, all patients experienced a reduction in skin toxicity.
- Fighting Skin Infections
Neem oil has anti-inflammatory and antibacterial properties that can help fight acne-causing bacteria as well as other skin infections. Researchers observed these benefits in cosmetic products and Ayurvedic soaps containing neem oil and other neem extracts 9. Other studies have also reported in vitro antiviral activity of neem against the Herpes simplex virus type-1 (HSV-1) 10.

Neem Oil For Hair
- Fights Hair Lice
Neem oil is an effective natural remedy for treating head lice infestations. Its strong insecticidal properties can help to destroy not just lice, but also their eggs. This is essential to control any hair lice infestation. Research shows that neem oil and seed extract can kill head lice larvae within just 5 minutes and fully grown lice within 10 minutes 11. These benefits are linked to the presence of azadirachtin.
- Fights Dandruff
Neem oil has anti-inflammatory and antibacterial properties that can help reduce the inflammation, itching, and flaking of the scalp caused by dandruff. It also helps prevent dandruff-causing bacteria and fungi from spreading. These benefits of neem oil for dandruff are linked to the presence of Neem’s active ingredient nimbidin 12.
- Moisturizes The Scalp
Neem oil is rich in fatty acids, such as oleic, linoleic, and palmitic acids, which nourish and moisturize the hair. It also contains vitamin E, which is an antioxidant that protects the hair from environmental damage and prevents moisture loss. Neem oil can help hydrate and soften dry, brittle, or frizzy hair.
- Heals Scalp Infections
Neem oil has antifungal and antiseptic properties that can help treat various scalp infections, such as ringworm, folliculitis, or seborrheic dermatitis. It works by killing the infection-causing microorganisms and soothing the irritated skin. Neem oil can also prevent scarring and promote wound healing on the scalp
- Promotes Hair Growth
Neem oil can help promote hair growth by activating the dormant hair follicles and increasing the anagen phase of the hair cycle. The anagen phase is the active growth phase of the hair, during which new cells are added to the hair shaft. Neem oil can also provide essential nutrients to the hair follicles, such as fatty acids, antioxidants, calcium, and limonoids
- Prevents Premature Greying
Neem oil can help prevent or delay the appearance of grey hair by preserving the natural pigment of the hair. It does so by inhibiting the activity of an enzyme called tyrosinase, which is responsible for the production of melanin, the pigment that gives the hair its colour 13. Neem oil can also nourish and condition the hair, making it look shiny and healthy
- Increases Hair Lustre
Neem oil enhances the natural shine and lustre of the hair. Its moisturizing properties help repair damaged hair cuticles, smoothing the hair shaft and imparting a healthy shine. Regular use of neem oil can revive dull and lifeless hair, making it appear vibrant and glossy.
Conclusion
To safely enjoy these neem oil benefits for hair and skin care, make sure to dilute neem oil with a carrier oil like coconut, jojoba, or almond oil before applying it to your scalp or skin. This is important because neem oil is highly potent and if used in a concentrated form can cause adverse reactions.
