Redken Acidic Bonding Concentrate PH Sealer 250 ml

Acidic pH Sealer, which has a pH value of 3-4, helps to seal the hair's cuticle. It locks the benefits of the Acidic Moisture Concentrate and Acidic Protein Amino Concentrate treatments into the hair and adds instant shine.

After applying an appropriate dosage of Protein and/or Moisture Concentrate, and after the treatment has worked for 5 minutes, apply 10-15 pumps of pH Sealer throughout the hair. Rinse out. Continue with Redken conditioner if desired.
