Although I've never found my hair to be paticularly sensitive to anything, humectants, proteins, oils, cones, etc it seems to take it all in stride, although because we have yet to see temps over 20 degrees for the last months I have reduced but not eliminated stuff with humectants. Maybe the comb of being coarse, thick, and porous and going grey contributes to this?

Maybe everyone's hair just has a mind of it's own.
