Redken Acidic pH Sealer is a concentrated protein conditioner for damaged or overprocessed hair. With an acidic pH of 3.0–4.0, it helps seal the hair cuticle and maintain the benefits of the previous treatment, while adding shine. From the first application, it reduces surface damage to the hair.

Apply after Acidic Moisture Concentrate and/or Acidic Protein Amino Concentrate. Leave the previous products on for 5 minutes, apply 10–15 pumps throughout the hair, then rinse. If it gets into your eyes, rinse immediately.
