what is the best test to find your hair's porosity?
Hi everyone!I just wanted to know if anyone could suggest the best way to test your hair's porosity?The strand in water test, i found to be not so helpful because whichever strand i put in water(i tried mine, my sister's and mother's hair strands), it float. When i tried the slip test, i found that some of my hair strands were smooth but some were bumpy. Hence i cannot reach a conclusion with regards to my porosity. Help?Thanks in advance!
