Porosity Guide

Porosity is why your
products aren't working.

More than curl pattern, porosity determines how your hair absorbs and retains moisture. It's the single most important factor in choosing the right products.

The Float Test

Test your porosity at home

Clean your hair first (buildup affects results). Take a strand and drop it in a glass of room-temperature water. Wait 2–4 minutes.

LowMediumHigh

Floats at top

Low Porosity

Cuticles are tightly closed — water can't penetrate. Hair is less porous.

Sinks slowly, hovers mid

Medium Porosity

Cuticles accept moisture at a balanced rate.

Sinks to the bottom

High Porosity

Cuticles are open or damaged — absorbs water (and loses it) fast.

Note: Buildup can affect results. Clarify first for most accurate reading.

💧

Low Porosity

Cuticles lie flat and tightly sealed, making it difficult for moisture to enter — but once inside, your hair holds it well. Low porosity is often genetic and most common in hair types 1A–2C.

Signs You Have Low Porosity

  • Products sit on top of hair instead of absorbing
  • Hair takes a long time to get wet
  • Hair takes a long time to dry
  • Product buildup despite regular washing
  • Hair feels dry despite conditioning

Loves

  • Aloe vera
  • Glycerin (moderate climate)
  • Lightweight leave-ins
  • Clarifying shampoos
  • Heat during conditioning

Avoids

  • × Heavy butters (shea, mango)
  • × Thick creams
  • × Protein treatments
  • × Coconut oil (protein-mimicking)

Routine for Low Porosity

1

Cleanse

Clarifying shampoo monthly to remove buildup. Gentle sulphate-free cleanser weekly.

2

Condition

Use heat (hooded dryer, steamer, or warm towel) while conditioning to lift the cuticle.

3

Leave-In

Water-based, lightweight leave-ins. Avoid heavy creams.

4

Moisturise

Liquid products penetrate better than creams — water or aloe vera based.

5

Seal

Very light oil (jojoba, argan). Avoid heavy butters.

Pro Tips

Apply products to warm, damp hair to aid absorption

Avoid protein-heavy products — they cause more buildup

Steam your hair regularly to open the cuticle

Medium Porosity

Cuticles are slightly raised and allow moisture in and out at a healthy rate. Medium porosity hair is the most balanced — it accepts treatments easily and holds colour and styles well.

Signs You Have Medium Porosity

  • Hair feels moisturised after conditioning
  • Products absorb reasonably quickly
  • Holds styles for a good length of time
  • Accepts colour and chemical treatments well
  • Generally manageable with regular care

Loves

  • Most conditioners
  • Protein treatments (moderate)
  • Leave-in creams
  • Most oils in moderation

Avoids

  • × Over-processing
  • × Excessive protein (causes brittleness)
  • × Neglect — medium porosity is forgiving but not maintenance-free

Routine for Medium Porosity

1

Cleanse

Sulphate-free shampoo or co-wash. Clean weekly or bi-weekly.

2

Condition

Standard deep conditioning monthly. Regular rinse-out conditioner each wash.

3

Leave-In

Medium-weight leave-ins. Flexibility here — cream or liquid.

4

Moisturise

Balanced moisture + protein routine. Don't over-protein.

5

Seal

Medium oils: sweet almond, grapeseed, or a light castor blend.

Pro Tips

Maintain with regular deep conditioning

Occasional protein treatment every 6–8 weeks

You have the most flexibility with product weight

High Porosity

Cuticles are raised or damaged, absorbing moisture quickly — and losing it just as fast. High porosity can be genetic (often in coily types 4A–4C) or acquired through heat, chemical treatments, or colour.

Signs You Have High Porosity

  • Hair gets wet very quickly but dries fast
  • Perpetually frizzy, especially in humidity
  • Tangles and breaks easily
  • Absorbs products fast but needs reapplication often
  • Looks dull or dry even after moisturising

Loves

  • Castor oil
  • Shea butter
  • Protein treatments
  • Heavy creams
  • Anti-humectants
  • LOC/LCO method

Avoids

  • × Humectants in high humidity
  • × Skipping sealant
  • × Sulphates
  • × Heat without protection

Routine for High Porosity

1

Cleanse

Co-wash between washes. Sulphate-free cleanser weekly maximum.

2

Condition

Protein-rich deep conditioner every 1–2 weeks. Regular detangling conditioner.

3

Leave-In

Creamy, heavy leave-in conditioner. LOC or LCO method essential.

4

Moisturise

Layer products: water → leave-in → cream → seal.

5

Seal

Heavy sealant: castor oil, shea butter, or mango butter to lock moisture in.

Pro Tips

Anti-humectants in humid weather to prevent frizz

Regular protein treatments to fill gaps in the cuticle

Apple cider vinegar rinses to temporarily flatten the cuticle
