Treating the hyponychium can be an easy feat, as can preventing it. Knight recommends keeping your nails neatly trimmed and to avoid any trauma to your nail bed, which is also what causes the hyponychium to grow. "Don't forget to show your nails a little love with some moisturiser or cuticle oil, and whatever you do, avoid biting or picking at the nails which will cause further damage," she says.
Similarly, Notton recommends using the Mylee Cuticle Oil Roller Pen (£8) regularly and not just on your cuticles, but on your Hyponychium too, to soften the skin, as well as Mylee Disinfectant Spray (£8) to disinfect and sterilise any nail tools you may be using, including cuticle removers and nail cutters to prevent infections.
"Ensure that you remove your gels or acrylics every two to three weeks and take a break from long nails every so often," Notton advises.
