Detailed Application Steps
- Dispense: Begin by dispensing 1-3 drops of the oil into the palm of your hand. For thicker or longer hair, you may gradually increase the amount, but always start small.
- Emulsify: Rub your hands together to evenly distribute the oil across your palms. This helps ensure a consistent application.
- Apply to Damp Hair: For strengthening benefits and frizz reduction, apply the oil to clean, towel-dried hair before any styling. Focus on the mid-lengths and ends.
- Apply to Dry Hair: To smooth frizz and flyaways, and to add shine, apply a small amount to dry hair as a finisher.
- Heat Protection: The oil provides heat protection up to 450°F (232°C), making it suitable for use before heat styling.

Troubleshooting
- Hair appears greasy after application: This indicates too much product was used. The K18 Molecular Repair Hair Oil is highly concentrated. Reduce the amount to 1-2 drops and apply only to mid-lengths and ends, avoiding the scalp.
- No noticeable improvement in frizz/shine: Ensure hair is towel-dried to a damp state before applying for optimal absorption. For dry hair application, ensure hair is clean and free of heavy product buildup. Consistent use is recommended for best results.
Maintenance
- Storage: Store the K18 Molecular Repair Hair Oil in a cool, dry place, away from direct sunlight and extreme temperatures.
- Cap Security: Always ensure the dropper cap is securely closed after each use to prevent air exposure, contamination, and evaporation of the product.
