When I had my hair analysis done I sent both grey hairs and my natural colored hairs. My analysis came back as having normal porosity.
I will say my hair feels drier and more porous, but doesn't necessarily act that way. I haven't made any changes in my usual product yet.
--I'm located in Western PA.
--I found NC in late 2004, CG since 2-2005, started going grey in late 2005.
--My hair is 3B with some 3A, texture-medium/fine, porosity-normal except for the ends which are porous, elasticity-normal.
--My long time favorite products are Suave & VO5 conditioners, LA Looks Sport Gel, oils, honey, vinegar.
