  • Best For: Young adults dealing with thinning hair, stress shedding, or wanting fuller hair naturally.

2. Castor Oil

  • Main Uses: Hair thickening, lash and brow growth, nail strengthening.

  • Benefits: Rich in ricinoleic acid, which supports scalp circulation and moisture retention. Also antifungal and antibacterial, making it good for scalp health.

  • Best For: People looking to thicken hair, grow lashes/brows, or strengthen brittle nails.

3. Coconut Oil

  • Best For: Everyday use for soft, shiny hair and glowing skin.

5. Jojoba Oil

  • Main Uses: Scalp balancing, skin hydration, makeup removal.

  • Benefits: Very close to skin’s natural sebum, so it balances oil production and soothes irritation. Non-comedogenic, so it won’t clog pores.

  • How to Use: As a scalp massage oil, facial oil, or blended with essential oils.

  • Best For: Oily or acne-prone skin, sensitive scalps, light hydration.

6. Olive Oil

  • Main Uses: Deep conditioning, scalp nourishment, skin softening.

7. Tea Tree Oil (Essential Oil)

  • Main Uses: Dandruff control, acne treatment, antimicrobial scalp care.

  • Benefits: Strong antibacterial and antifungal properties that help with itchy, flaky scalps and breakouts.

  • How to Use: Always dilute (with jojoba or coconut oil). Massage onto scalp or apply as a spot treatment for acne.

  • Best For: Dandruff-prone scalps, oily/acne-prone skin.

8. Almond Oil

  • Main Uses: Hair softness, skin hydration, soothing irritation.

  • Benefits: Rich in vitamins A, E, and omega-3 fatty acids, it nourishes hair and skin while reducing inflammation.

  • How to Use: As a scalp massage oil, lightweight moisturizer, or to remove makeup.

Things to Keep in Mind

  • Essential vs. Carrier Oils: Essential oils (rosemary, tea tree, peppermint) must be diluted in a carrier oil before applying to skin or hair.

  • Patch Testing: Always test on a small area to check for reactions.

  • Consistency: Oils usually show results over time (weeks to months).

  • Quality: Look for cold-pressed, pure, or organic oils to ensure potency and safety.
