There is never a shortage of new treatments and technologies aiming to combat hair loss. Laser treatments are now available and designed to boost growth by exposing hair to low intensity laser light, which helps energize the hair follicle. These treatment can be done by a dermatologist however, several "at-home" products such as laser combs and hats have entered the market. Professional treatments over several months of weekly sessions may help give you the boost your follicles need but the jury is still out about the "at home" devices.
A newer but older method is called microneedling, which uses tiny sterilized needles to pinprick the scalp to promote hair regeneration. Costing around $1200 per treatment, microneedling claims to promote hair regeneration by triggering wound healing responses and increase absorption rates for topical treatments.
Note: At home kits are also sold but please take caution and speak to a professional before attempting.
