Hair Porosity Test:

What It Is & Which Oil Works Best

Hair porosity refers to how well your hair absorbs and retains moisture. Knowing your porosity level helps you choose the perfect oils and treatments for stronger, healthier, smoother hair.

Understanding your porosity = choosing the right product = better results.

How to Do the Hair Porosity Test

1. The Float Test
  1. Take a strand of clean, dry hair (no oil, conditioner, or product).

  2. Drop it into a glass of room-temperature water.

  3. Watch what it does in 2–4 minutes:

  • Floats on topLow porosity

  • Stays suspended in the middleMedium/normal porosity

  • Sinks quickly to the bottomHigh porosity

Understanding Each Porosity Level

Low Porosity

Low Porosity Hair
  • Cuticles are tightly packed

  • Moisture has trouble entering, but once in, it stays

  • Hair can feel oily on top but dry inside

  • Product buildup is common

Best Harrington's Oils for Low Porosity

Use lightweight oils that absorb quickly:

Jojoba Oil
Argan Oil
Lavender Hair Oil (light, soothing)
Healthy Hair Oil (balanced blend)

These oils mimic natural scalp sebum and penetrate slowly without heaviness.

Medium Porosity Hair

Medium Porosity Hair
  • Cuticles open just enough for moisture to enter

  • Retains moisture well

  • Most products work effectively

Best Harrington’s Oils for Medium Porosity

You can use both light and medium-weight oils:

Coconut Oil
Biotin Booster Oil
Rosemary Oil
Hair Mist (for hydration & shine)

These support strength, hydration, and natural shine.

High Porosity Hair

High Porosity Hair
  • Cuticles are raised, gaps allow moisture to escape

  • Hair dries fast, gets frizzy, breaks easily

  • Often caused by bleaching, heat, and chemicals

Best Harrington’s Oils for High Porosity

Choose heavier, sealing oils to lock in hydration:

Castor Oil (very thick, excellent for sealing moisture)
Onion Oil (growth + cuticle repair)
Thickener Oil
Coconut Oil (300ml) to deeply condition
Avocado Oil (rich, nourishing, repairs damage)

High porosity hair benefits most from richer formulas that fill cuticle gaps and prevent moisture loss.
