The float test is pretty inaccurate. Take a strand of hair & run your fingers from tip to root. If u feel bumps, chances are its porous. If your hair gets wet quickly & dries quickly, it's likely porous. If it seems to take some effort to get it soaking wet & it takes a long time to dry, that signals low porosity. LP hair is difficult to moisturize properly. HP hair can generally benefit from protein to repair the holes in the cuticle.
