I have CG for 2 days only, amazing for me plus no products, just so I can get a feel of real hair type I plan to continue for a week at least.

However some parts very frizzy some not so bad, the obvious dry areas (top layer) frizzy.

So from everyone’s super experience what’s the best porosity test please?

Thank you!

I have heard that the test where you see if hair floats (not sure on the details) is possibly one of the harder to interpret.  I think how quickly your hair dries without product on it can be a sign, also running your fingers up a hair strand (ie. in the opposite direction to growth) - does it feel bumpy, rough or resistant to the motion or smooth.  If it feels as smooth upward as when moving downward, it may be relatively low porosity.  Also, if you’ve had colour done professionally, did they comment on whether your hair took up the colour fast - that could be due to porosity.  If your hair is currently chemically or heat damaged, the damaged areas will probably be higher porosity than your natural level.
