it looks like they used to fade their hair on the sides but no longer likes to? id recommend maybe balancing the top out if possible so it doesnt look as disconnected
To ask bluntly do they want to improve their hair/style/makeup or do you want them to improve their hair/style/makeup (and if they want to why are they not posting themselves)
we don't know anything about this person other than what they look like shoulders up in a black t shirt and what hair and makeup look 'best' depend a lot on their usual style and interests etc etc
