To rebuild and protect – use in damp hair

1. Shampoo the hair and rinse, repeat
2. Apply a hair mask for extra hydration
3. Towel-dry the hair
4. Apply the Bond Builder section by section
5. Do not rinse. Style as desired.

When used in damp hair, the cuticle is open, allowing the Bond Builder to rebuild internal bonds and strengthen the hair, and create a protective neo-cuticle to protect from future damage.

To soften and shield – use in dry hair
Apply to dry hair as a finishing touch on dry hair to smooth lengths and provide an additional protective barrier against external damage. Use Bond Builder as the first layer in your usual styling routine.
