past hairdresser here, I voluntereed for 4 years for the American Cancer Society doing wigs for our county, rewarding but hard.
Locks of Love is a whole different ballgame. Real hair wegs are Very expensive to make and require a lot of care/upkeep. As far as I know LofL didn't do freebies unless you were famous.
Having had cancer 3 times this decade, I've been around a lot of cancer patients and about 1/2 (areound here anyway) do even bother with wigs, they go bald proudly, or wear cute caps and hats.
When you are bald any kind of wig is itchy. and hard to keep in place.
