EXTREME LENGTH Sealer by Redken is a treatment that seals split ends to prevent breakage and promote the growth of healthy and resistant hair.

The EXTREME LENGH line has been created to accelerate hair growth and maximize its length, as its products fortify hair from roots to ends, repairing fiber damage and effectively sealing split ends, thus helping get up to +15 cm in length in a year.

This treatment exclusively combats split ends and works by extremely softening the fibers to facilitate their detangling and thus avoid breakage.

In addition, its formula has been enriched with Biotin, also known as Vitamin H, an active ingredient that accelerates and stimulates hair growth, helping to go from short hair to dazzling hair faster.
