I have a 50-year-old client who has been having recurring ingrown nails on her fingers. It tends to affect the middle and ring fingers on both hands, and on both sides of the nail. She starts to feel sensitivity to pressure on her fingers and within days you can see pus under the skin. It looks like a small piece of nail is growing into the skin, causing the infection (and quite a bit of pain). She has hard, brittle nails that she wears short and polished. Is there anything I can do in the salon to prevent this from happening so often?
