Madonna is a health freak who has an army of personal trainer, nutritionists, physicians, etc checking her every week. She probably gets a full body MRI every month to detect anything early. She'll live until her 90s.
It's obviously to make her hair blow all over the place so she can look like she's a Goddess or something. Why don't any of the other gerls use em, hm?
She doesn't have more or less fans than the average popstar.
