Chap, one with hint about right treatment for hands (8)
I believe the answer is:
manicure
'chap one with hint about right' is the definition.
I can't judge whether this definition defines the answer.
'treatment for hands' is the wordplay.
'treatment' becomes 'cure' (medical treatment).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'hands' becomes 'mani' (I can't justify this - if you can you should give a lot more credence to this answer).
'cure' put after 'mani' is 'MANICURE'.
Can you help me to learn more?
(Other definitions for manicure that I've seen before include "Hands/nails treatment" , "Work on nails" , "A numeric approach to care of the hands" , "Cosmetic nail treatment" , "Cosmetic care of the hands" .)
