Eyelash extensions are applied in salons by specially trained therapists. Individual lashes are carefully bonded to your existing lashes.
Extension lash is applied to each of your existing lashes, around 80 to 100 of them. Alternatively you can get a half-set for a more natural look.
When you arrive at the salon, the therapist will talk to you about what you want - how long the lashes should be, how thick, and even what kind of curl. During application the eyes will be protected and closed. You shouldn't feel any pain or discomfort.
How Long Do Eyelash Extensions Last?
Around eight to 12 weeks if you look after them. The extensions will drop off as your eyelashes naturally shed, so you'll lose about 12-15 lashes every two to three weeks. Beauty therapists recommend returning for touch-ups, for which they will charge you a small fee based on how long it takes them to replace what you've lost.
Maintenance
For the first 24 hours after getting lash extensions, the adhesive is still setting - so don't touch them or get them wet. After that you shouldn't need mascara, but if you do use any products on or near your lashes, they must be oil-free.
