I work in a salon and a client came in asking for eyelash extentions, i've been taught to put the eyelashes on top of the natural lashes but this client asked me to put them underneath the lashes i thought she meant on the lower eyelid " No" she said "on the top eyelid" she said she has them done this way before i asked her to explain she said that the therapist pulled up her top eyelid and began sticking the false eyelashes under the natural lash instead of on top. I did not do the treatment as i have never done it this way before. I was wondering if it is okay to do the treatment that way, and what do other therapist think about it? what are the risks? and has anyone done it this way before?
