iRestore Essential 120 Laser Hair Growth System - Very Lightly Used The devise works wonderfully, I paid $750 but I keep forgetting using it . This is an FDA-cleared system that not only fights hair loss and thinning but also helps with regrowth. The I-Restore helmets "deliver more power and light energy than other comparable devices on the market. Expect visible results in just 3 to 6 months." *Please be mindful this item is already discounted AND Poshmark takes 20% ($90+)
