You could try the porosity test:
Put some strands of hair (clean with no product) in a bowl full of water (lay them on top of the water). If they sink to the bottom then your hair is highly porous, if they stay in the middle it's "normal", if they float it has low porosity.
The cuticle can be raised slightly (it takes very sensitive instruments to detect this – the distance can be as little as one millionth of a meter). Running your fingers down a strand to feel for a raised cuticle is simply not possible unless you have severely damaged hair.
It looks like you're new here. If you want to get involved, click one of these buttons!
