If you love what you do and clients still want you to continue, why not? I'm fifty soon and although i trained a couple of years ago. Living in france held me back. I now live in Italy and i'm gonna go for it!. I do think perhaps the age of clients might grow with us but to be honest if you have done a youngster nails and they love them, they'll be back! I do think our appearance will have an affect though ( so musn't look to grannyish). I don't think we would attract new clients if we looked like we were about to be committed to the nearest home. Just had a thought though, one could always continue with our new found clients!
Just want to say how much i enjoy 'The Nail Geek' It's brilliant! Have picked up so much info already. It would be nice to have some feedback from younger techs. Don't worry girls (boys) us oldies have tough skin lol.
