Garnier 7.40

Look for shades described as deep or ash with clear undertone notes, such as Deep Ashy Blonde for cool results or Gold-Yellow tones for warmth. The oils present in the formulas help deliver a smooth application and long-lasting colour, so you can expect a balanced payoff across roots and ends. Real-world cues like uniform tone and maintained shine indicate strong pigment uptake.

The nourishing oil blend supports colour retention by helping hair stay hydrated and less prone to breakage during washing. While no dye lasts forever, the combination of rich pigment and conditioning oils helps maintain colour depth and shine across several weeks, reducing noticeable fading compared to harsher or drier formulas.

Yes. Ash tones are typically well-suited for silver or grey blends because they counter brassiness and blend evenly with grey strands. The line’s ash-heavy options are designed to deliver consistent coverage and a cooler final look, while the oils preserve softness and manageability after colouring.

Expect a glossy, healthy-looking finish thanks to the olive oil and additional natural oils present in the mix. The formulation aims to deliver not only even colour but also a level of shine that makes the final look more natural and vibrant, particularly on lighter bases where brightness is more noticeable.

When undecided, consider the undertone you prefer and how your current hair colour sits on warm versus cool scales. If you want a brighter result with a warmer glow, choose the lighter warm shade; for a cooler, more neutral look, pick an ash shade. The nourishing oil blend remains constant, supporting hair health regardless of the final shade.
