Yellowing nails

[rachy86]

Hi there,
I did a set of nails on my mum the other day.I used the edge tips and tried my trial set of NSI l&p a day after I had don the nails mainly the thumbs had started to go yellow and discolour.She does not smoke and had not been on any sunbeds or had her hands in any hair colour or such.
I am quiet confused :S any suggestions guys?

Hi ya,
it could be that your brush is contaminated with old product....try dipping your brush in clean monomer and then wipe on kitchen towel...if it leaves yellow streaks it is contaminated and you'll either have to try clean it or get a new brush.
HOpe this helps, the only other thing I know that causes yellowing is sun beds, which you say your mum hasn't used.
