While I do not believe it’s necessary to shave your hair off early on, wig shopping is another matter. Once you know your hair will probably soon be a thing of the past, if you choose to buy a wig, the sooner you do it the better.
First of all, the further you get into chemo, the less likely it is you will feel like going out to wig shop, or shop at all for that matter. As fatigue and other side effects kick in, you just might not feel up to the task.
