There are three different levels of porosity:
1. Low porosity Hair: this is when the cuticle of the hair shaft is too tight compacted and does not let moisture in or out. Low porosity has a tendency to repel product rather than absorb it.
2. Hair with Medium porosity is considered "normal" hair. With normal porosity, the cuticle is compact and stops most moisture from leaving or entering the hair shaft and will readily absorb and retain product properly formulated for this hair type.
3. Hair with high porosity also classified as "overly porous" is the result of heat damage, chlorine/hard water/mineral saturation, sun damage, or use of harsh ingredients. Overly porous hair is damaged in some way, and is dry, fragile and brittle because of the open cuticle that both absorbs and releases moisture easily. Although overly porous hair absorbs product quickly, it is often dry as the open cuticle does not allow for product retention within the hair shaft.
You can check your Porosity level by plucking (yes plucking ) a few strands from your hair and placing them in a glass of water ( it wont hurt and if it does you wont die ! I promise ) ..... If your strands sink to the bottom quickly you have overly porous hair
if it stays on top and takes a long time to sink you have low porosity, if it floats somewhere in the middle then congrats you have normal porosity !
You need to determine your hair type and your hair porosity, and then think about what types of products are best suited to your particular hair type. Other factors will come into play, but these two hair properties are the most important properties to know.
