Most stylists spend their days removing unwanted hair. Jennifer is a whiz at trendy cuts, but she is also quite adept at adding hair where it's desired. She helps her clients with chemically and thermally damaged hair repair, rejuvenate, and even regrow locks with laser-light hair-therapy treatments. Each session works by blanketing heads with a hovering hood outfitted with low-level laser diodes that stimulate cell activity and blood flow to the scalp.
