Using Hair Oil on Damp Hair
Applying hair oil to damp hair is one of the most effective ways to support hydration and reduce dryness. Damp hair still contains water within the hair shaft. Applying oil at this stage helps seal that moisture in before it evaporates, supporting longer-lasting hydration. Benefits of applying hair oil on damp hair include:
Seals hydration for smooth, shiny hair
Protects against frizz and breakage
Helps ensure even application of nourishment
How to Apply Hair Oil on Damp Hair
When applying oil to damp hair, for best results:
Remove excess water so hair is damp, not dripping
By removing excess water you prevent oil from simply gliding off the strands, allowing it to penetrate and seal the hair
Warm a small amount of oil between your palms
This helps to ensure even application of the hair oil, so every strand gets enough nourishment
Apply to both scalp and lengths
You can apply to both the scalp and lengths depending on your haircare goals, applying to lengths nourishes the strands and helps retain moisture, while applying to the scalp evenly helps to encourage healthy hair growth
Using Hair Oil on Dry Hair
Hair oil can also be applied to dry hair, where it works as a both a nourishing or finishing step. Benefits of using hair oil on dry hair include:
Adds shine and smoothness
Reduces frizz and flyaways
Allows gradual daily buildable application before washing as part of an intense nourishing treatment
Protects hair from environmental exposure
Helps dry ends feel softer
How to Apply Hair Oil on Dry Hair
Applying hair oil to dry hair can be a versatile part of your routine, whether you want to smooth frizz, add shine, or build up nourishment for an intensive pre-wash treatment. Here’s a simple step-by-step guide:
Apply in small, buildable amounts, daily or as desired
Start with a little, you can always add more to gradually increase hydration and nourishment
Add a small amount for shine or instant frizz-free smoother hair
Warm a few drops of oil between your palms and lightly smooth over the hair to enhance shine, softness, and manageability.
Apply to lengths and scalp for deep nourishment
Focus on both the mid-lengths and ends and the scalp for a deep treatment
Massage or smooth through hair
Use your fingers or a wide-tooth comb to evenly distribute the oil. This ensures each strand receives the oil for smoothness and manageability.
Pre-wash treatment
For an intensive hydration treatment, apply gradually leading up to your hair wash day, and apply more oil overnight the night before washing. For a lighter boost of nourishment, leave on for at least 1-2 hours before washing.
Common Hair Oil Mistakes to Avoid:
Applying oil to dripping wet hair
Using too much product at once
Applying oil without hydrating hair first
Concentrating oil too close to the roots unnecessarily
