These days, a wide variety of brow and lash treatments is available in salons. These treatments can last from 15 minutes for brow threading to an hour for the application of glamorous extensions. Your therapist will usually ask you to sit in a chair similar to that at the hairdressers, or to lie down on a special treatment bed. They will then work their magic, before instructing you on how you can look after your new brows or lashes at home. Simple!
