FAQs — Redken Extreme Length Sealer

1 - What is this treatment and who should use it?

• A leave-in treatment designed to seal split ends and strengthen hair from the inside, ideal for clients trying to grow their hair long or those with fragile, breakage-prone lengths.

• Recommended for hair that is fine, fragile, chemically treated, heat-styled, or prone to splitting at the ends.

2 - What benefits does it provide?

• Helps lock in strength and reduce breakage, supporting healthier hair growth over time.

• Seals split ends and reinforces hair fibre integrity, making ends less prone to fraying or breaking.

• Improves manageability and softness, making hair easier to detangle and style — helpful for long or textured hair.

• Adds resilience against mechanical stress (brushing, heat styling) and environmental stress (dryness, friction), helping maintain length and health.

3 - How should it be used (salon or at-home)?

1. Apply on clean, towel-dried (or slightly damp) hair, focusing on mid-lengths and ends — especially areas prone to splitting.

2. Leave in — do not rinse. Proceed to style as usual (air-dry, blow-dry, etc.).

3. Can be used after every wash, or whenever hair feels fragile, ends feel dry, or after chemical/heat services — frequency depends on hair condition and client needs.

4 - Will it weigh hair down or interfere with styling?

• Generally no — the formula is designed to be lightweight and leave hair soft, manageable, and styling-ready rather than heavy or greasy.

• For very fine hair, using a small amount is recommended to avoid potential heaviness while still getting the sealing benefit.

5 - Why choose this sealer instead of a regular conditioner or treatment?

• Because it focuses on sealing and protecting ends and lengths — not just temporary softness — it supports long-term hair health and growth preservation.

• It helps minimize breakage and damage between salon services or during frequent styling, maximizing the results of treatments and colour services.

• Works well as part of a consistent hair-care routine (cleanse → sealer → protection/styling) — gives clients a practical solution for maintaining strong, healthy hair over time.
