In the United States, eyelash extension services can range from $60 to $500, depending on:
The number and type of lashes being used
The skill level of the cosmetician or
The venue where the extensions are applied
Because an average person might have anywhere from one hundred to two hundred lashes per eye, it can take from one to three hours to attach a full, new set. The amount of lashes one can put on varies upon the existing natural eyelashes. Because we lose natural eyelashes every day the eyelash extensions usually last between 3–4 weeks and during that time period, natural lashes start falling out or thinning. Maintaining a full set of eyelashes requires a refill every 2–3 weeks or a partial set every four weeks. If done correctly, there should be no damage to the natural lashes. It is important to find a trained professional to preserve lash growth and reduce the chance of eye complications.
