I am a type 2c, with dry, frizzy unmanagable hair. The top layer being the most frizzy.
The strands themselves are course; if I run my fingers along the length of a strand of hair it seems quite thick and varies in thickness - it feels quite bumpy.
The thing i’m not sure about is whether my hair is pourous or not.
It takes an age to wet my hair in the shower and the water seems initially to just run off it, however once it is wet it then takes an age to dry as it seems to hold on to the water. I did read that if you put a strand of hair into a bowl of water and it floats it is not pourous. I did this and it floated - but I did have product on my hair at the time which could prevented the water being absorbed into the strand.
