When Seida Chapa opened her own salon, she staffed it with trained stylists who inject industry trends into their menu of services. In addition to haircuts and color treatments, they calm frizzy tresses with keratin and chemical straightening treatments. Spa specialists can give collagen a boost, expel fat, and improve circulation with Bioslimming wraps, and aesthetic specialists use glycolic-acid peels to help subdue wrinkles, dead skin cells, and large pores. Eyelash extensions and eyebrow threading make peepers pop, as do traditional and permanent makeup services. Staffers also primp hands and feet with mani-pedis, or craft custom wigs made out of human hair harvested from John Stamos's immortal scalp.
