BIO SPECTRA ATTITUDE Colorlast Shampoo for Color-Treated Hair — 67.6 fl oz Refill, EWG-Verified & Vegan, Avocado + Pomegranate

BIO SPECTRA ATTITUDE Colorlast Hair Shampoo is a large refill bottle of EWG-verified, plant-based cleanser formulated to help protect and gently cleanse color-treated hair while adding moisture.

This concentrated 67.6 fl oz refill is designed for people who want a cleaner, kinder shampoo for dyed hair without sacrificing performance. Made from predominantly naturally derived ingredients, it uses pomegranate extract and avocado oil alongside botanical actives to help maintain vibrancy and hydration. The formula avoids silicones and SLES, is certified vegan, and carries an EWG verification for ingredient transparency.

How does this shampoo help preserve hair color?

The formula includes pomegranate extract and gentle surfactants chosen to minimize color stripping while removing buildup. Regular use with a matching conditioner helps reduce early fading and supports a softer, shinier finish.

• Pomegranate extract: antioxidant-rich to help protect surface pigments.
• Plant-derived surfactants: cleanse without harsh dye removal.
• Pairs with Colorlast conditioner for improved color maintenance.
• Fragrance chosen to complement rather than overwhelm treated hair.

What makes this a "clean" or EWG-verified product?

The bottle carries EWG verification, meaning its ingredients meet specific safety and transparency criteria. Most of the formula is of natural origin and the blend excludes common harsh ingredients often avoided by clean-beauty shoppers.

• 97% naturally derived ingredients for a milder profile.
• Free from silicones and SLES for gentler cleansing.
• EWG Verified — assessed against the Environmental Working Group’s standards.
• Dermatologically tested and certified vegan.

Will this shampoo moisturize dry, color-treated hair?

Yes — avocado oil and botanical nutrients help replenish and lock in moisture while the gentle cleansing base avoids over-drying. It’s formulated to balance hydration with effective cleansing for mid-to-dry color-treated strands.

• Avocado oil: helps seal moisture into the hair shaft.
• Watercress and Indian cress extracts: support strengthened, resilient hair.
• Designed for regular use without stripping natural oils.
• Suitable for pairing with conditioner for added softness.

What does it smell like and how concentrated is the refill?

The scent blends peach blossom and melon with subtle woody undertones for a fresh, lightly sweet fragrance that won’t overpower. The 67.6 fl oz refill is sized for multiple months of regular use, making it practical for home and salon-top-up refills.

• Fragrance notes: peach blossom, melon, pine, and anise hints.
• Large refill size reduces packaging waste and cost-per-wash.
• Concentrated enough for repeated refills of standard bottles.
• Formulation avoids heavy residues that can mask scent.

Who is this for: This refill is aimed at anyone with color-treated hair seeking a cleaner, plant-forward shampoo option — including people who prefer vegan products, EWG-verified formulas, or large-format refills for home or professional use. It works well for those wanting a gentle cleanser that helps maintain shine and color while delivering extra moisture from botanical oils and extracts.
