I don't have the time to go to a salon every 3 weeks. It's not 45 mins, it's driving there, having the appointment, driving back. Plus if one of the DC is sick that day/something happens, I've lost the appointment and still get charged. Then I have to rebook. Or if one chips or breaks, it's all that palava to go in and get it fixed, or live with it looking crappy until the next appointment. No nails look better than chipped nails.
I bought myself a gel lamp (£14.99 Amazon), I use a fantastic brand of Portuguese gels (about a tenner each on Amazon) and I only use the natural pink builder gels. One has a sparkle to it which is really pretty.
I do them whichever evening suits me, in front of a film, around every 3 weeks and they literally paid for themselves from the first time I did them. First few attempts took much longer because I couldn't do my wrong hand, but I'm very good at them now, to the point people ask me where I get my lovely nails done.
My mother couldn't believe you could make your own nails look like this at home, bought herself a little set up too, and now hers look better than mine.
