This was my first ever eyelash perm. I went in without massive expectations because I knew the results depend a lot on your natural lashes. I was shocked at the result!! The difference was immediately noticeable. My lashes look really good a week after, it's basically like having mascara on all the time, with no effort :) the only thing I would have changed is that I didn't get any 'guidance' on how to maintain them, for example it's really important to not get the lashes wet within 24 hours, and I learned that online as opposed to being told at the salon. But overall I'm really happy with how they look and the service was efficient and relaxing!
Disclaimer: my lashes are naturally long but they don't naturally 'curl up'. I think you'll get really good results like mine if you have long lashes already, and you want to give them a lift.
