Try a Porosity Test!
porosity test #1
Take a strand of hair from your comb or brush and drop it into a clear glass of water. If the hair strand floats to the top, your hair is low porosity. If the strand slowly sinks toward the bottom, your hair is normal porosity. If the strand immediately sinks to the bottom, your hair is high porosity.
porosity test #2
Run a few strands of hair between your thumb and index finger, starting at the ends and moving up the hair shaft toward the scalp. If the strands feel smooth, your hair is likely low to normal porosity. If the strands feel rough, your hair is likely high porosity because the cuticle layer is loose and open, causing the rough feeling of the exterior of the hair strand.
