And the opposite: permanent hair removal. My partner went through a laser treatment for over an year to get about 60-70% reduction in hair growth. It's immensely painful and time taking process that doesn't work for all akin colors and doesn't guarantee a permanent hair removal. With the current pace of medical research I would have imagined a simple cream that you apply on your skin and whoosh all the hair follicles would be permanently dead. But for some reason, it seems like a distant dream.
