I have been getting my lashes done at Inglewood Beauty Bar for about a year now, and have fantastic things to say about my stylist, Elaine.
Elaine is very cautious, particular and thorough. I have seen other stylists at other places and nobody beats her handiwork - she rocks. She's also patiently resolved some of the poorer craftsmanship that I've received at other places, and I always leave looking 10 times brighter than when I walked in.
My personal bias: eyelash extensions are the best thing ever, especially if you are as lazy about putting on makeup as I am.
Although a little on the pricey side, the service is always good (e.g., I always get a reminder call), and parking is right there and free. I'd definitely recommend IBB (and especially Elaine) for lashes in Calgary.
