Yes, it is not uncommon for hair from different parts of the head to have a different texture.

• 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...

• Yes, Course Hair normally has low porosity. Always test four parts of the head for porosity:
• Hairline, temple, crown and nape.
