- Frequently Asked Questions
Method 1: Leave-In on Damp Hair
The most common and effective method. After washing, apply 2-3 drops to damp hair, focusing on mid-length to ends. Air dry or style as usual.
Why it works: oil seals in the moisture from water and conditioner. Result: less frizz, more shine, easier detangling.
Method 2: Pre-Shampoo Treatment
Apply generously to dry hair from roots to ends. Wait 30-60 minutes. Shampoo out (may need 2 shampoos to remove).
Why it works: oil protects hair from the stripping effects of shampoo. Heavy oils (coconut, olive) work best for this method.
Method 3: Mixed with Conditioner
Add 2-3 drops of oil to your regular conditioner in your palm. Apply as normal.
Why it works: the conditioner carries the oil into the hair. Less work than applying oil separately. Good for occasional boost.
Method 4: Overnight Treatment
For very dry hair, apply a small amount to ends before bed. Cover with a silk or satin pillowcase. Wash out in the morning.
Why it works: extended contact time allows deep penetration. Use heavier oils (coconut) for overnight.
Method 5: Styling Serum
A tiny amount (1 drop) on dry hair to add shine and tame flyaways. Do not over-apply or hair will look greasy.
Why it works: oil provides light hold and shine for natural styling. Not a substitute for hairspray or gel but works for soft looks.

Hair Oil: 5 Best Practices
Practice 1: Use 1-3 drops for shoulder-length hair. More weighs down hair.
Practice 2: Apply to mid-length to ends, not roots. Avoid flat, oily roots.
Practice 3: Apply to damp hair for best penetration. Oil + water = barrier. Apply to towel-dried hair.
Practice 4: Warm oil in palms before applying. Improves spread and absorption.
Practice 5: Choose the right oil for your hair type. Lightweight (argan, jojoba) for fine/oily. Richer (coconut) for thick/dry.
See our pre-shampoo treatment and argan oil for oil guidance.
Hair Oil: Choosing the Right Oil for Your Hair Type
For fine or oily hair: lightweight oils (argan, jojoba, marula). Use 1 drop. Apply only to ends. Avoid heavy oils that weigh down.
For medium to thick hair: most oils work. Argan, coconut, olive, avocado. 2-3 drops. Apply from mid-length to ends.
For curly or coily hair: heavier oils (coconut, castor, olive). 3-5 drops. Apply as part of LOC/LCO method. Focus on sealing moisture in.
For color-treated hair: lightweight oils with antioxidants (argan, jojoba). Avoid heavy oils that may affect color retention.
Hair Oil: Timing Matters
Apply on damp hair (after washing, towel-dried): oil seals in moisture. Best for hydration.
Apply on dry hair: oil adds shine, tames flyaways, controls frizz. Best for finishing.
Pre-shampoo treatment: oil protects hair from shampoo stripping. Best for damaged or very dry hair.
Overnight treatment: oil penetrates deeply. Best for severely dry hair. Use heavy oils (coconut) and cover with a shower cap.
Hair Oil: Common Mistakes
Mistake 1: using too much. 1-3 drops is enough for shoulder-length hair. More weighs down hair.
Mistake 2: applying to roots. Roots are usually oily enough. Apply from mid-length to ends.
Mistake 3: using the wrong oil for hair type. Lightweight (argan, jojoba) for fine/oily. Heavy (coconut) for thick/dry.
Mistake 4: not washing out heavy oils thoroughly. May need 2 shampoos to fully remove.
Mistake 5: using oil on freshly bleached hair. Wait 2 weeks after bleaching before using oil-based treatments.
Oil Combinations: Best Mixes
Argan + jojoba: lightweight, all hair types. Good for daily use.
Coconut + olive: rich, thick hair. Good for pre-shampoo treatments.
Argan + coconut: balanced, medium hair. Good for damaged hair.
Marula + baobab: premium, lightweight. Good for fine to medium hair.
Castor + jojoba: scalp-focused. Castor for thickness, jojoba for moisture.
Oil: Best Time of Day to Apply
Morning: after showering, apply oil to damp hair for daytime moisture and shine.
Afternoon: 1 drop on dry hair to tame frizz and add shine.
Evening: 1-2 drops before bed to nourish hair overnight. Use heavier oils for this.
Pre-workout: skip oil. Sweat + oil can make hair look greasy.
Hair Oil: Best Practices for Storage
Store hair oils in dark glass bottles to protect from light. Light degrades active compounds and reduces shelf life.
Keep oils in a cool, dry place. Avoid bathroom humidity. Some people refrigerate oils to extend shelf life.
Use within 6-12 months of opening. Pure carrier oils last 12-24 months unopened. Essential oils last 2-5 years.
Check for changes: smell (rancid oil has an off smell), color (changes indicate oxidation), consistency (separation indicates contamination). Discard if any of these occur.
Hair Oil: A Quick Recap
Hair oil is one of the most versatile hair care products. Use lightweight oils (argan, jojoba) for fine or oily hair. Use heavier oils (coconut) for thick or dry hair.
For brand owners, hair oil enables premium positioning and customer loyalty. Quality and sustainability matter more than specific ingredient claims.
