Bonding Serum is a necessary step when using our products. It allows you to straight, set and position the hairs in the correct direction. Bonding serum is also used to protect the hairs from direct penetration however, it is soluble which means it will begin to dissolve as you apply step 1, 2 and 3. Remember to only apply a small amount so not to create too much of a barrier.
Our timings have been created with the use of bonding serum therefore if you choose not to use it, you should reduce your timings to prevent over processing.
