Between day 14 to 17 for the moult. Grt your self a little cap in readiness. I started wearing one when prepping food as its better than eating it. My hairdresser clipped mine as it was less stressful. But little bits grow back and keep falling out between cycles so I always capped when cooking and sleeping.
If you google chemo hats the sites come up. Hathouse and hatshow were great. One has like a starter kit...sleep cap, wig liner, fan band (to help hold a normal hat or scarf) and I think you choose another one of your choice. ( A tip sand volour is skin colour...and so you just look bald). Haha. The bamboo ones are fantastic but a little expensive.
I never wore a wig but my bamboo wig liner I wore under wooly caps in winter to stop the itch and drafts if the big open crochet sort.
