What Is Hair Porosity? The Ultimate Guide for Curly Hair

What is hair porosity? and why should you care?

If you’ve ever wondered why your bestie’s curls conditioner works wonders on her curls but leaves yours flat and frizzy? The secret often comes down to hair porosity. Porosity is your hair’s ability to absorb and retain moisture, and it plays a huge role in how products perform for you. Whether your hair soaks up products like a sponge, repels water like it’s waterproof, or lands somewhere in between, knowing your porosity is the key to building a haircare routine that actually works.

Low Porosity Hair:

Water beads on the surface, showing that it struggles to penetrate the strand. Products like oils and creams sit on top of the hair without absorbing easily.

High Porosity Hair: Raised or Damaged Cuticles. meyer curls

High Porosity Hair:

Water quickly sinks into the hair strand, but it also evaporates fast, leading to dryness and frizz. Hair quickly absorbs products but struggles to retain moisture, requiring constant rehydration.

Medium/Normal Porosity Hair: Balanced Cuticles. meyer curls

Medium Porosity Hair:

Water and moisture are absorbed and retained well, with some water slowly seeping in. Products are absorbed at a steady rate, and hair retains moisture effectively.
