well heres the thing acv does remove grease and oils well..but greasy hair tends to be more acidic acv makes hair more acidic .. removing oilds triggers oil production as well
normaly doing bs without acv will make it more dry..often too dry but some who use the bs too weak say they get a grey scalp mud thats the exfoliated skin in a passte form this maybe the greasiness u think u feel
so id try a stronger bs a acv rinse but weak and short and experiment from there to get the right mix
plus washing too often will try]=iger oil production so space out the washings 1 day longer
