How To Use It
Starting with the dosage syringe (tip facing up), pull back the plunger to allow a little air inside the barrel.
Insert the tip of the syringe into the b3 Brazilian Bond Builder 4oz. / 120 ml bottle and turn upside down.
Pull the plunger back to the desired amount, pushing any overage back into the bottle.
Remove dosing syringe from the bottle. Dispense and mix into your lightener, color formulation, or b3 Demi Permanent Conditioner.
