Renew Salon & Skin Care's Shanna Lynn bedecks lackluster lashes with Shavasana extensions. Initial eyelash installation takes one?two hours, during which Shanna secures single strand semipermanent Shavasana extensions to feeble fringes, hair by hair. The results are longer, thicker eye trimmings, giving you the confidence necessary to wink at strangers and unleashed dogs. After 48 hours, the freshly lashed can frost the extensions with mascara. A refill, which lasts less than 60 minutes, is recommended within two?three weeks.
