If you follow the "example" of others who have lost their hair after chemo, be prepared for some fun. If your hair was straight before, it very well may grow back finer in texture, and curly. My husband just went for the Telly Savalas look (are we showing our age?), and waited for the cute new growth. Sad to say, now (10+ months later) it is back to straight like before. Hat, or wig? I would say go with whatever seems comfortable for you, and matches your personality. Maybe both??
