Shampoo BIOSILK Color Therapy Cool Blonde — for cool-toned blonde hair, 355 ml

BioSilk Color Therapy Cool Blonde Shampoo is formulated for cool-toned, highlighted and lightened hair. The sulfate-free shampoo helps neutralize brassy warm tones and unwanted yellowing, enhancing cooler blonde shades while supporting colour vibrancy and shine. Packaged in a 355 ml bottle, it is suitable for regular use as part of colour-care routines.

Advantages

The sulfate-free formula gently cleanses without stripping colour and contains a violet tint that neutralizes yellow and brassy tones in grey, white and blonde hair. It helps maintain a healthier-looking, shinier and more vibrant cool blonde shade between salon visits.

Suitable for

• Highlighted or lightened blonde hair with warm/brassy tones
• Cool-toned blondes seeking tone maintenance
• Grey or white hair with unwanted yellowing
• Coloured hair requiring gentle, colour-safe cleansing

When it may not be suitable

This product is designed specifically to neutralize warm and yellow tones; it may not be necessary for natural dark hair or brunettes without brassiness. Users with very porous or heavily damaged hair should monitor results, as tone-correcting shampoos can sometimes emphasize underlying warm pigments.

Key specifications

• Volume: 355 ml
• Formulation: sulfate-free shampoo
• Action: violet tint for tone neutralization
• Primary benefits: reduces brassiness, enhances cool blonde tones, adds shine

How to use

Apply to wet hair, lather and leave on for 1–3 minutes depending on the desired level of toning, then rinse thoroughly. For best results, follow with a conditioner suitable for colour-treated hair and use regularly to maintain cool blonde tones. Adjust contact time based on hair porosity and colour intensity.

What to consider before purchase

• Intended for cool-toned, highlighted or lightened hair
• Not a permanent colour treatment—results are temporary and depend on usage frequency
• Test on a small section first if hair is very porous or previously chemically treated

Usage recommendations

Use once or twice weekly as needed to maintain cool blonde tones; alternate with a regular colour-safe shampoo on other washes to avoid over-toning. If stronger toning is required, increase contact time gradually and monitor results.
