So I placed five strands (3c/4a) of my hair in a bowel of water, after 3 minutes, nothing happened and they stayed floating. I thought I might be cheating so I stirred the strands. 4 stayed floating and one sunk (it was the shortest of all the strands), we'd be at the four minute mark by now. I quit the test after 6 minutes, the other strands never sunk.

Does this mean I have low porosity or is it more like normal/high since one strand did eventually sink?

I know my hair is protein sensitive as well, special protein masks and conditioners always make my hair feel dry and straw-ish.
