By now you know the wigs are adjustable, she can tighten to a little uncomfortable level when going out in the wind? Plus the two way tape of course. I don't know, it's always hard and all women have their own feelings about how the need to look to feel comfortable.

It was very hard for me to lose my eye brows and lashes, I've never left the house without my eye make up so was very upset not to wear mascara. Kind of weird, I know...
They will be falling out any time and will take longer to come back. Mine never did come in as full or long but that could be age related since they thin out in middle age any way.
She can buy an eyebrow pencil and pencil them in, it's better than nothing.
On a positive note, I shave my legs every two weeks compared to every day prior to chemo
