Clairol choice (4)
I believe the answer is:
tint
'clairol choice' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tint that I've seen before include "Quality of colour" , "'Shade, tone (4)'" , "Hue, shade" , "Hair dye" , "A slight shade of colour" .)
