Lasers have recently come into use in hair restoration. A laser is used to encourage blood flow around existing follicles. However, there are some that say the method doesn't really work, and even in the best-case scenarios the results are less than spectacular.
Effective hair restoration is a big deal, so don't expect it to be cheap. Hair restoration doesn't come in a can or a poultice, no matter what anyone says -- it's generally a lengthy and expensive procedure accomplished through surgery or careful cosmetic work.
Be careful when considering any hair restoration treatment involving "structured hairpieces." These are hairpieces that are literally stitched onto the scalp, which heightens the possibility of complications. Many ethical surgeons will no longer perform these procedures.
