Around one and a half billion people across the globe are bald or have some form of hair loss.
Now a company in California has come up with what it claims to be the solution -- a helmet that fires cool lasers at the wearers scalp to stimulate hair growth.
The Theradome headgear is said to be the only wearable, clinical-strength laser treatment that people can use at home, but it will set buyers back almost $800.
It claims to grow healthy new hair, double the follicle size of existing hair and can even prevent hair loss.
"Getting your hair back is a convenient and affordable process," the company said.
Theradome lets people use this advanced technology at home, and contains high efficiency lasers that produce virtually no heat but allow the maximum amount of light to be delivered, the company claim.
It contains 80 lasers, so that light can reach 90 square inches of the 111 square inch average scalp area.
Users of the device are meant to wear it for 20 minutes at a time, twice a week.
For the first 18 to 24 weeks of use, it is designed to reverse the shrinking of hair follicles to stop further hair loss.
"You will find you have cleaner, more manageable hair with improved lustre and fuller body, decreased oiliness and larger hair shafts. You'll also find less hair fallen out in the shower and on pillows," the company said.
After 28 weeks of regular wear, the helmet claims to set about regrowing hair by increasing blood flow to the scalp and hair follicles, stimulating microcirculation and improving the metabolism of cells.
It reduces the effects of protein blocking enzymes, promoting thickness and density, the company said.
