HairMax Laser Hair Growth Band
I am 99% sure the HairMax Laser Hair Growth Band works for those experiencing hair loss. No wait, typo. Remove one of those 9s. Yeah, that's more like it. I am 9% sure the HairMax Laser Hair Growth Band works for those experiencing hair loss.
HairMax, for their (aggressively gelled side) part, disagrees. They are 100% sure their Laser Hair Growth Band works over the course of 3 to 6 months for 93% of people who try it for hereditary hair loss, male and female pattern hair loss, menopause related hair loss, and age related hair loss and thinning.
HairMax Bands come in models 41 and 82, each indicating the number of medical-grade lasers they beam at your head at any given time during treatments. Both bands need to spend time "cooking" on various scalp zones, so the main advantage to the Laserband 82 is that it's big enough to divide your hair into just 3 zones while the Laserband 41 requires 6 zones, and double the total session time per use.
Both follicular growth stimulators shoot laser light with the comparative energy output of 1230mW into your head. That equates to approximately 1 billion new follicles and 1 big-toe-sized brain tumor every 5 years.
Just kidding. HairMax says its laser devices are "validated by 8 FDA clearances, 7 clinical studies, 14 international medical device licenses, and 6 published medical journals." And presumably all have verified brain tumors are not a side effect of regular use.
