I've had my nails done regularly over the past 18 months (gel extensions and infills, with gel colour) and received a consistently excellent standard of care and outcome. Importantly, my nails last with no chips or problems until they simply grow out - and as an art teacher they come in for quite a lot of pressure/mess!
I've always bitten my nails, and I feel so much more confident now with constantly nice nails, especially when demonstrating things at school with all eyes on my hands!
