What is hair porosity?

A hair typing method that is used to describe how easily your hair absorbs and retains moisture through the cuticle.

context: Your hair strand is made up of layers. The outter layer (cuticle) is shaped like fish scales that lay flat on the hair strand. These cuticles can be naturally or changed to be more lifted or quite flat.

Your hair may be classified as having high (lifted cuticle), medium, or low (flat cuticle) porosity.

What are the characteristics of low porosity hair?

The hair shaft is packed with cuticles that grow really close to each other - laying very flat. This makes the cuticle layer thicker than medium and low porosity hair.

It's hard for product to penetrate the hair shaft. But once it does, hair feels nourished the longest.

What are the characteristics of medium porosity hair?

Hair cuticles are spaced out in a way that eases product penetration and retention - they are neither too wide or narrow.

Hair texture retains moisture longer than high porosity hair.

What are the characteristics of high porosity hair?

Hair cuticles are widely spaced and slightly lifted, making it easy for hair to absorb hair products and lose moisture.

High porosity hair is characterised by hair feeling dry or dehydrated sooner than other porosity types.

How can I accurately test my hair's porosity?

Wash and dry hair with minimal product (e.g. use a rinse out conditioner. no additional product if you air dry & heat protectant if you use heat).

Take a few dry hairs and slide your fingers along the hair shaft towards the root.

low porosity - the cuticle feels mostly smooth

high porosity - the cuticle feels mostly rough

porosity can vary throughout the whole head.
