If everyone is using Stabilized enchants that means they already got it to +6... don't really get why you are complaining.
Eva's Scroll: Enchant Hair Accessory: is what you should be using to get it to +6
Stabilized Eva's Scroll: Enchant Hair Accessory: Can only be used at+6 or higher.
The real problem is getting this Stabilized Eva's Scroll ONLY, when you need the regular Eva's Scroll.
