I had lash extensions done for a good few months and loved them. Cabinkel on here did them and she was very good. I never found they were any trouble. you had to look after after but it was no big deal and just like nails you go back every few weeks to have them filled.
Hi i trained with Hollywood Lashes Hands On Beauty - Training Academy (this is the trainers website and there is a link on there for the lashes) they are fantastic i've done them for about 18 months now and i have regular customers every 2 weeks. They don't suit everyone unfortunatley! They say they last up to 3 months but they've got to have top ups done every 2-3 weeks as we shed our lashes. This treatment has taken over my nails and is very popular for Xmas. I charge £80 for a full set and infills are £20. I'd send you a pic but not sure how to add it on here.
My Mom and sister wore them for MONTHS. You just have do touch-ups about every 2-3 weeks. I tell people it's like getting your nails done. The full set is the big money part but keep up is a breeze. I charge $295 for the amount in the picture and then touch-ups start at $35, but is based on how many lashes are applied.
