For eyelash extensions the client lies with closed eyes while the lower lash line is taped down. The practitioner isolates individual natural lashes and attaches synthetic lashes made of PBT plastic. In the 1:1 method (Classic) one extension is placed on one natural lash; for a denser effect, volume or hybrid techniques use handmade fans of several ultra-fine lashes. Thickness, length and curl are matched to eye shape and natural lash so the weight doesn't overload your own lash.
A new set takes 1.5 to 2.5 hours depending on technique. Since each natural lash has its own growth cycle and sheds after four to eight weeks, the set gradually thins. That's why a refill is done every two to three weeks, replacing lashes that have grown out. With proper care – no rubbing, oil-free cleansing, no plucking – the extensions stay even and the natural lashes healthy.
The treatment suits anyone wanting a bright, defined look without daily mascara, as well as holidays, events or contact-lens wearers. An experienced practitioner using high-quality, skin-friendly adhesive is important, as eye irritation or allergies can rarely occur. A professionally applied set does not damage the natural lashes as long as it is properly refilled and removed.
In Switzerland a Classic new set usually costs CHF 120 to 180, volume or mega-volume sets CHF 160 to 250 (no guarantee). Refills usually cost CHF 60 to 120 depending on interval and technique. Professional removal is often CHF 20 to 40.
