GLISS Fiber Therapy Shampoo & Conditioner Set 2×13.6 fl oz – For Extremely Damaged Hair, Strengthening & Smoothing

GLISS Schwarzkopf Hair Repair Fiber Therapy is a shampoo and conditioner duo formulated to help strengthen and visibly restore the look and manageability of extremely damaged hair.

This two-bottle set from GLISS by Schwarzkopf includes a 13.6 fl oz (400 ml) shampoo and a 13.6 fl oz (400 ml) conditioner designed for very damaged, brittle, or porous hair. The products use a fiber-repair approach to temporarily rebuild surface structure, smooth the hair fiber, and reduce the appearance of split ends and rough texture after repeated chemical or heat exposure. The pair is intended for routine use as part of a restorative haircare routine.

How does the Fiber Therapy system work on badly damaged hair?

The Fiber Therapy formulas target weakened points along the hair shaft, replenishing key components to improve resilience and smoothness. They form a protective layer that helps prevent further mechanical damage while improving detangling and softness.

• Shampoo gently cleanses without stripping the hair's moisture balance.
• Conditioner seals and smooths the hair surface for easier combing.
• Temporary fiber-repair technology fills in gaps on the hair surface.
• Regular use supports improved manageability and reduced roughness.

Will this set help reduce breakage and split ends?

The GLISS Fiber Therapy duo is formulated to minimize friction and strengthen fragile lengths, which can lead to less breakage during brushing and styling. It doesn't permanently eliminate split ends, but it can make hair look healthier and feel smoother between trims.

• Strengthening agents help fortify weakened strands.
• Smoothing conditioner action reduces knotting and friction.
• Improved combability lowers mechanical stress from styling.
• Works best when combined with gentle handling and regular trims.

How should I use the shampoo and conditioner for best results?

Apply the shampoo to wet hair, massage to create a gentle lather, then rinse thoroughly. Follow with the conditioner, focusing on mid-lengths to ends; leave it on for one to three minutes before rinsing to let the formula smooth and seal the fiber surface.

• Use on wet hair; shampoo to cleanse, then rinse completely.
• Apply conditioner mainly to mid-lengths and ends; avoid roots if oily.
• Leave conditioner in for 1–3 minutes for optimal smoothing.
• For very damaged hair, pair with occasional treatments from the same range.

Is this set suitable for color-treated or chemically processed hair?

The duo is formulated to be compatible with hair that has undergone chemical or color treatments and aims to improve appearance and manageability without harsh stripping. As with any colored hair, test a small section first and follow color-care recommendations from your stylist.

• Designed to support chemically processed and color-treated hair.
• Does not claim to prevent color fading; use with color-safe routines.
• Gentle cleansing helps maintain moisture balance in treated hair.
• For best color longevity, combine with dedicated color-protect products.

Who is this for: This GLISS Schwarzkopf Hair Repair Fiber Therapy shampoo and conditioner set is aimed at people with extremely damaged, brittle, or over-processed hair seeking a practical daily pairing to improve softness, manageability, and visual repair. It fits consumers who want large 400 ml bottles for regular use and prefer a fiber-focused approach rather than intensive salon treatments.
