Hair can become burned out from constantly gripping the skull, which is when it rebels and runs away to join a bearded lady at the circus. Coax strands into staying with today's Groupon: for $99, you get a three-month low-level-laser hair-restoration treatment at Hair Replacement Clinic Dayton (a $975 value).

HRC Dayton's trained laser technicians bolster thinning scalps with three months of low-level-laser hair therapy, a nonsurgical, FDA-cleared treatment that attempts to improve hair volume and shaft quality and to prolong hair color. The therapy saturates skin with a cold, red light beam of electromagnetic radiation that stimulates microcirculation of the blood supply to speed up the body's natural healing processes. This encourages regrowth to cover bald spots—prime targets for vindictive pigeons flying overhead.

HRC Dayton's technicians recommend clients schedule one 15- to 30-minute session per week. Clients can usually see reduction in hair loss within 6 treatments and some hair growth within 12.
