In general all mall including those in Aeon, literally everyone who operate quick cut types of saloon raised price to around RM28/cut from RM15/cut, even Cyberjaya Old Town Area the quick cut although not RM28 but is very close to it already.
Then if rental is the cause I don't see other shop having such drastic price hike in % compared to these saloon.
If mahal. Need to go cheaper place lar. Anneh/woren barbershop at those normal shoplot shud be cheaper
