Ability of hair to absorb and maintain hydration. This is similar to the more or less strong opening of the hair scales.

• High porosity: the scales are very open, water easily enters the hair fiber but comes out immediately. The hydration does not stay there.

Advice:
- Use protein treatments to strengthen the hair;
- Use cold water in the shower to close the scales;
- Seal hydration with a fatty substance (oil) to prevent water from escaping

• Normal porosity: good balance of the hair which absorbs and maintains hydration properly
  
• Low porosity: the scales are closed, water enters with difficulty into the hair fiber. The same goes for the care provided which can quickly give the feeling of heavy hair.

Advice :
-Prefer fluid/light treatments that will not weigh down your hair;
- Favor hot water at the start of the routine which will open the scales;
- From time to time, use a clarifying (or detox) shampoo to remove excess hair products remaining on the surface of your hair;
- Advice to carry out oil baths once every 2 weeks for example using light oils which will penetrate more easily.

Each hair type is divided into 3 subcategories a, b and c depending on its thickness and curl type.

Knowing your hair type can be useful in defining a suitable hair routine. Curly hair will have a greater need for hydration and nutrition than straight hair. A little science to explain it simply: the natural sebum secreted by the scalp has more difficulty flowing along the hair fiber the tighter the curl. However, sebum protects the hair scales and directly contributes to maintaining its hydration. The lengths of curly and frizzy hair will naturally tend to be drier than straight hair and require superior care.
