How does Scruples Renewal Shampoo protect hair color?

The formula focuses on gentle cleansing agents and ingredients that minimize color loss during washing. It reduces the amount of pigment washed away and helps maintain a true-to-tone appearance for longer.

• Mild surfactants cleanse without aggressive fading
• Color-locking components help reduce pigment runoff
• pH-balanced to avoid opening the cuticle excessively

Will this shampoo work on dry or damaged color-treated hair?

Yes — Renewal Shampoo is formulated to be moisturizing while cleansing, so it can help hair feel softer and more manageable after color services. It won't replace a deep conditioner but pairs well with treatments to restore texture and shine.

• Hydrating elements help reduce roughness and frizz
• Gentle enough for regular use without over-drying
• Compatible with conditioners, masks, and leave-ins

How should I use the 33.8 fl oz bottle to get the best results?

Use a quarter-sized amount for short to medium hair and more for longer or thicker hair. Lather, rinse, and repeat if needed; follow with your preferred conditioner or treatment for optimal softness and color longevity.

• Wet hair thoroughly before applying shampoo
• Massage into scalp for 30–60 seconds to lift impurities
• Rinse and follow with a conditioner to seal the cuticle

What makes this 33.8 fl oz size a smart choice?

The larger bottle gives better value per use and reduces the frequency of repurchasing, useful for households with multiple color-treated users or for professional salons. It’s packaged for stability and easy dispensing so you can measure consistent amounts each wash.

• Economical for regular at-home maintenance
• Convenient for salon back-bar or family use
• Durable bottle for stable storage and handling
