A client has sent me these photo's of her acrylics shes had them on about 5 weeks now and i infilled them just over a week ago. She messaged me saying that 3 of her nails have gone yellow shes not sure what she has done but she says they do not hurt. I asked if any of them have lifted and if there could be a chance water has got underneath but she says no they havent lifted at all. She said they arent green they are yellow and i was taught in college that fungal infections are green. The client is very heavy on her hands so is it possible that it could be bruising?? im going today to soak the nails off as i advised her this would be best so i can see whats going on under the acrylics. I was thinking of advising her to have shellac on instead of the acrylics until the yellowing (which im hoping is bruising has gone) is this what everyone else would advise??
