Formulated for anyone with colour-treated hair, permanent or semi-permanent, who wants to slow fading between salon colour services. It's a professional-brand shampoo meant to be used by the client at home for daily maintenance, not applied in-salon as part of a colour service itself.

The distinguishing feature here is the pH-balancing approach: because washing itself is the main driver of colour fade, matching the shampoo's pH to hair, sebum and scalp is meant to keep the cuticle closed and pigment sealed in rather than just adding a color-safe label to a standard cleanser. That's the mechanism behind Kenra's stated 35-wash, 67%-fade-reduction claim for colour-treated hair.

Wet hair thoroughly, apply the shampoo to the scalp and roots first, and massage in. Rinse, then work any remaining lather through the lengths and rinse again. Repeat only if hair is very oily or product-heavy; daily use doesn't require double-washing for the colour-protecting effect to apply. Follow with a matching colour-safe conditioner to complete the system.

Pros:

• pH-balancing system targets one of the main causes of colour fade, repeated washing, rather than just cleansing hair
• Honey and blueberry extracts double as conditioning agents, adding shine without a separate treatment step
• Paraben-free formula gentle enough for daily use per Kenra's directions

Cons:

• Contains sodium laureth sulfate and sodium lauryl sulfate, so it is not a sulfate-free shampoo despite the colour-protecting claim
• The 35-wash / 67% fading-reduction figure is Kenra's own lab claim tied to consistent use; results can vary with heat styling, sun exposure or hard water
• Best paired with Kenra's matching Colour Maintenance Conditioner for the stated results; using it alone may not match the brand's published numbers
