How long does hair take to fall out?

Can’t help too much in that regard, I hardly wore them, except tied under straw hats (actually made of paper, very soft and hard wearing- still have them!). The scarfs, knotted to the side, were both colourful and fashionable. Otherwise I wore a wig, had two, although I favoured one and wore it nearly all the time (but the other was great when I accidentally frizzed the one I was wearing when opening a hot oven - only down side of synthetic wigs!). Not everyone likes them but I found a wig great - light, no problem to wash/dry, no styling required, and - best of all, as I worked through chemo - no odd looks/explanations/awkwardness when dealing with the general public as I did a lot. What each person chooses is really personal, and most work out pretty quickly what suits them and their life best, for the duration. Best wishes.
