Biolage Strength Recovery Shampoo for Damaged Hair — 33.8 oz salon-size, sulfate-free with olive squalane & vegan proteins

Biolage Strength Recovery Shampoo is a sulfate-free cleansing formula micro-dosed with olive squalane and vegan proteins to gently detangle and increase strand strength after one use.

This concentrated 33.8 oz salon-size bottle is created to support damaged, brittle, or chemically treated hair without stripping color. The lightweight formula cleanses while depositing small, targeted doses of nourishing olive squalane and plant-based proteins to help improve manageability and reduce breakage during styling. Its vegan formulation makes it suitable for shoppers seeking ingredient transparency and gentler surfactants than traditional shampoos.

How quickly will I notice reduced breakage and easier detangling?

Many users report smoother combing and less snap after the first wash because the formula aims to condition as it cleans. Results depend on hair condition, but the micro-dosed actives provide immediate slip and progressive strengthening over repeated use.

• Immediate: improved wet combing and reduced knotting after one use
• Short term: less visible frizz and fewer breakage points after several washes
• Best practice: follow with Strength Recovery Conditioner for cumulative benefits

What ingredients make this shampoo better for damaged hair?

The key actives are olive squalane and vegan proteins chosen to replenish moisture and fortify the hair fiber. Olive squalane helps smooth the cuticle, while plant proteins temporarily fill weakened areas, improving tensile strength without weighing hair down.

• Olive squalane: lightweight hydrator that boosts softness and smoothness
• Vegan proteins: strengthen strands and help reduce snapping during styling
• Sulfate-free surfactants: cleanse while minimizing excess moisture loss and color fading

Can I use it on color-treated or chemically processed hair?

Yes — the gentle formulation is designed to be compatible with color-treated hair and various chemical services. It focuses on preserving moisture and reducing friction, which helps maintain color vibrancy when used as part of a recovery routine.

• Safe for color-treated hair when used as directed
• Formulated to maintain softness and reduce breakage post-service
• Pair with color-safe conditioners and treatments for best results

How should I incorporate this shampoo into my routine?

Use it as your primary cleansing step whenever you need to repair and strengthen. Massage into wet hair, rinse, and follow with Strength Recovery Conditioner; for targeted repair, finish with the Strength Recovery Repairing Spray on damp hair.

• Use on wet hair — lather, rinse, repeat if necessary
• Follow with Strength Recovery Conditioner for added reinforcement
• Use Repairing Spray for concentrated leave-in support between washes

Who is this for: Biolage Strength Recovery Shampoo is aimed at people with damaged, over-processed, brittle, or color-treated hair who want a gentler, salon-grade cleanser that also provides conditioning slip and progressive strengthening. It’s suited to those seeking vegan ingredients and a non-stripping wash that pairs well with a restorative haircare regimen.
