Hello,there are some ladies on here that have used cold caps,but I am pretty sure that you have to use them from the very beginning.If your hair has started to fall out,I think you will find that it keeps on happening.I actually had the hairdresser shave my head 5 days before I started chemo.The little prickly bits started to fall out on day 14,and my eyebrows fell out that week also! I actually grew to love being bald,andI NEVER thought I would say that!!!Quick showers because no hair to wash and style,no leg shaving,money saved on hairdresser,drive with the window down, When my hair started to grow back I was disappointed!!It is thick and wavy now,and before it was straight!! My suggestion is to try and accept your hair loss,and look for some of the gorgeous scarves,turbans and hats you can buy.Before you know it your hair will be growing back.Cheers xoxRobyn
