In 10 years of getting nail extensions, I have never had a bacterial infection of the nail from dirty equipment - until now! I’ve been getting my nails done here for a few months. My last appointment was 2.5 weeks previously, and my nails were fine. Today I went and my thumb nail had turned GREEN. They tried to claim I had banged my thumb and it was a bruise. A quick Google showed it was Pseudonomas, a bacterial infection caused by the use of unclean equipment. This is your warning - avoid!
