Taxotere - cold cap, hairloss, regrowth

Just thought I would ask… I have had 5/6 tax using the cold cap and my hair has held on (though it is thinner). Having just brused it I think it is getting a bit fragile and I wouldn’t be surprised to lose more of it. Has anyone been in a similar situation and if so how and when did your hair start growing back?
