-
Texture
Course, Medium & Fine
-
Course Hair Texture
Largest in diameter. Stronger... Think rope... Requires more processing
-
Medium
The most common - The standard to which all other hair is compared. Does not pose any special problems
-
Fine
Smallest diameter - most fragile - easier to process. more susceptible to damage from chemical service that course or medium.
-
Can Texture vary from strand to strand
Yes, it is not uncommon for hair from different parts of the head to have a different texture.
-
Porosity
- The degree of porosity is the directly related to the condition of the hair. Healthy hair has a compact cuticle layer and naturally resistant to penetration = High Porosity
- Overly processed hair = overly porous hair and allows moister to penetrate vs repelling off... Takes longer to dry etc...
-
Can hair texture help determine porosity?
- Yes, Course Hair normally has low porosity. Always test four parts of the head for porosity:
- Hairline, temple, crown and nape.
-
Elasticity
Ability to stretch and return. Dry hair stretches 20% of the lenght. Hair with low elasticity is unable to hold curl from wet or thermal drying or permanent wave. Lower PH process required.
-
Density
Is the number of hair per sq. inch. How many hairs on the head, Low, Med, High. Average is 2200 per sq. in with a total average of 100,000. Color helps determine density
-
Density per natural hair color
Blond Hair = 140K, Brown 110K, Black = 108K and Red = 80K
