What Is Garlic Oil?
Garlic oil is prepared by infusing crushed garlic cloves with a carrier oil (such as olive oil) or by steam distillation of garlic. The result is a potent oil that acts as both a flavor enhancer and a therapeutic compound. Garlic oil retains many of garlic’s core active ingredients, including allicin, sulfur compounds, flavonoids, and vitamins.
Nutritional Profile of Garlic Oil
Garlic oil is a treasure trove of nutrients and bioactive compounds:
- Vitamins: B1 (thiamine), B6 (pyridoxine), C, E
- Minerals: Selenium, manganese, zinc, potassium
- Sulfur Compounds: Allicin, diallyl disulfide (DADS), diallyl trisulfide (DATS)
- Flavonoids: For antioxidant effects
- Amino Acids: Histidine, arginine, cysteine, methionine, phenylalanine
This nutrient richness underpins garlic oil’s diverse health, skin, and hair benefits.

Garlic Oil for Skin Health
Garlic oil is especially popular for skincare due to its antimicrobial, anti-inflammatory, and antioxidant properties:
- Reduces Acne and Blemishes: Garlic oil combats Propionibacterium acnes and soothes inflammation, resulting in clearer skin.
- Treats Fungal Infections: Helps fight athlete’s foot, ringworm, and candida due to potent antifungal activity.

Garlic Oil for Hair Care
One of the most acclaimed uses for garlic oil is in hair care:
- Stimulates Hair Growth: Sulfur-rich allicin promotes blood circulation to the scalp, encouraging new growth.
- Strengthens Hair Strands: Improves hair structure and prevents breakage by fortifying the hair shaft with essential vitamins and minerals.
- Reduces Hair Loss: Topical use and supplementation may aid recovery from conditions like alopecia areata, as shown in recent clinical studies.
- Combats Dandruff and Scalp Disorders: Antifungal and antibacterial actions help manage dandruff, itching, and ensure scalp health.
- Adds Shine: Oil baths or serums with garlic oil restore luster to dry or dull hair.
Recent scientific investigations have shown promising results for garlic oil in treating alopecia areata — a form of hair loss. The active compounds in garlic are believed to stimulate the Wnt/β-catenin signaling pathway, contributing to new hair follicle formation and increased stem cell activity.
How to Use Garlic Oil for Hair
- Combine 1–2 tsp garlic oil with your regular hair oil or conditioner.
- Massage gently into the scalp; leave for 30–60 minutes before washing.
- Weekly treatments can help reduce dandruff and support hair growth.
- Do not apply directly to broken or inflamed skin.
If sensitivity occurs, dilute further or discontinue use. More scientific studies are needed to confirm long-term efficacy in diverse hair loss conditions.
Other Health Benefits of Garlic Oil

- Detoxifies the Body: Acting as a natural cleanser, garlic oil aids liver function and helps purge toxins.
- Promotes Exercise Performance: Historical accounts and modern studies suggest garlic oil can reduce fatigue and enhance endurance.
