Matrix SoColor Beauty Extra Coverage Color 3oz Matrix brand decided to reformulate and improve all its colors SoColor and SoColor Sync (formerly Color Sync), which are now Pre-Bonded - ie. are enhanced with bond protection technology. These new formulas will give you and your hair much more support and protection during the whole dyeing process. Otherwise, everything you know and love about the original SoColor products has remained unchanged. The shades and uses are completely identical. Please note: If you order DEVELOPER 3oz you will NOT be receiving the Large Bottles, but the Smaller bottle shown above. (Either white cap or black cap 3oz bottle with NO Lable, NO ORIGINAL BOTTLE, NO SEAL) Please feel free to ask. Thank You. BIG BOTTLES NOT INCLUDED.
