How Is Vegetable Oil Good For Your Hair?

Vegetable oils are rich in carbohydrates and essential nutrients that can repair damaged hair. Many cosmetics formulation contains vegetable oils as they help improve the cuticles and increase hair softness (1).

However, do not pick any random jar of cooking oil from your kitchen shelf to use on your hair. Cooking oils are processed and may not contain the essential nutrients your hair might need. Always use unprocessed, cold-pressed, and virgin vegetable oils (like virgin coconut, olive, jojoba, and argan oils) on your hair.

Here is how vegetable oils may benefit your hair:

1. Hair Conditioning

Vegetable oils (like sunflower and coconut oils) condition the hair. They penetrate the hair and reduce the rate of water absorption, minimizing swelling and hair damage. Vegetable oils reduce hygral fatigue (repeated swelling and drying) to prevent hair damage (2).

2. May Prevent Dandruff

Coconut oil may help prevent the growth of Malassezia, a yeast-like fungus that causes dandruff. A study found that those who applied coconut oil to the scalp had a less severe case of dandruff (3).

3. May Promote Hair Growth

Olive oil may promote hair growth. A study found that oleuropein, the main constituent of olive leaves and fruits, encouraged hair growth in telogenic mice (4).

4. May Prevent Scalp Inflammation

Vegetable oils like olive, grape seed, sunflower, coconut, safflower, avocado, peanut, sesame, and jojoba oils contain essential fatty acids that prevent oxidative damage, inflammation, UV damage, and skin barrier degeneration. Almond oil helps prevent itching and soothes the skin (5). All these vegetable oils may also have a similar effect on the scalp and help maintain optimal scalp health.

5. Protects Hair From Heat Damage

You can use a few drops of any vegetable oil as a hair protectant. The vegetable oil coats the hair and shields it from damage caused by heat styling tools. It also adds shine and bounce to the hair and shields it from environmental damage.

  • Tocopherols (antioxidants)
  • Phospholipids (act as permeability enhancers and anti-inflammatory agents)
  • Squalene (emollient and natural antioxidant)
  • Linoleic acid (maintains skin barrier)
