So i found out that the fix for the custom content blonde hair streak bug is to turn off laptop mode, however i had been experiencing very bad lag problems every time i turned it off so i gave up trying to fight it, however, i played around with the settings for a little bit and found that they DID reduce the lag a LOT, eventually it got to a point where my game was completely playable with reduced lag as well as having reasonably good graphics and those horrible blonde streaks in my CC hair were gone!
