Nail keratin layers. Coloured scanning electron micrograph (SEM) of layers of keratin within a nail. Here,several nail layers have been peeled back to reveal a flattened interlocking structure for the keratin units. This structure helps explain why nails are hard and also why they are translucent. Keratin is a protein that is also found in skin and hair | |
