Dead skin (7)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
cuticle
'dead skin' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for cuticle that I've seen before include "Dead skin at nail's base" , "Dead skin on hand" , "finger has one" , "layer of protection" , "Skin at foot of nail" .)
