Should I Use Hair Oil on Wet or Dry Hair?

Hair oil is a staple in many haircare routines, and there are many benefits to applying oil to both dry or damp hair. The key lies in understanding how hair oil works at different times, making it easier to use hair oil for your haircare needs effectively, without weighing hair down or causing buildup.


What Hair Oil Actually Does

Before deciding when to apply hair oil, it’s important to understand its role. Hair oil works by:


  1. Supporting moisture retention

  2. Reducing moisture loss

  3. Smoothing the hair cuticle

  4. Adding shine

  5. Improving softness and flexibility

  6. Supporting healthy hair growth

  7. Protecting hair from friction and environmental stress

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:


  1. Seals hydration for smooth, shiny hair

  2. Protects against frizz and breakage

  3. Helps ensure even application of nourishment



How to Apply Hair Oil on Damp Hair

When applying oil to damp hair, for best results:


  1. 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

  2. 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

  3. 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:


  1. Adds shine and smoothness

  2. Reduces frizz and flyaways

  3. Allows gradual daily buildable application before washing as part of an intense nourishing treatment

  4. Protects hair from environmental exposure

  5. 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:


  1. Apply in small, buildable amounts, daily or as desired

    Start with a little, you can always add more to gradually increase hydration and nourishment

  2. 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.

  3. Apply to lengths and scalp for deep nourishment

    Focus on both the mid-lengths and ends and the scalp for a deep treatment

  4. 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.

  5. 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:


  1. Applying oil to dripping wet hair

  2. Using too much product at once

  3. Applying oil without hydrating hair first

  4. Concentrating oil too close to the roots unnecessarily

  5. Rubbing hair aggressively during application
