I consider my hair porous. I did the "run" test. Interestingly it didn't catch, but on the part that is still color processed I felt some bumps, so may be that's the caught part. Otherwise hair was smooth. Haven't done the sink or float test.

Playing with my hair is a hobby. Fluffy, fine natural 4a. Goal= Healthy, beautiful hair that retains its length.
Hear that crash? It's me falling off the CG wagon.
