From Blonde to Grey: How to Achieve the Perfect Cool Grey Without Yellow Tones (Guide + Tips) 🩶
Grey isn’t just a hair color – it’s a statement. Cool, elegant, futuristic and incredibly versatile.
That’s why in January we’re celebrating not just one but two Colors of the Month: Grey Skull and the Allergic to Color Color Mask! 🎉💙
Both are discounted all month long – the discount is automatically applied in the cart 🛒.
But to achieve a cool, clear, radiant grey, your base has to be perfect. And that’s exactly where things often go wrong: yellow tones.
Here’s your complete step-by-step guide to achieving a flawless grey result without unwanted warmth – including rescue tips, product advice & pro insights.
🧊 Why Yellow Tones Ruin Your Grey
Grey shades – just like pastels – are among the most demanding colors. The pigments are light, delicate, and very transparent.
Any trace of yellow will shine through, making your result:
warmer than intended
grey-beige instead of silver
or, in the worst case, even slightly greenish

💡 The 5-Step Plan: How to Transform Blonde into the Perfect Grey
1. Step: Create the Right Base – White Blonde 🔥
For Grey Skull (our Color of the Month!) you need a truly white-blonde base.
Why? Grey Skull has a subtle blue-violet undertone that neutralizes yellow – but only if the remaining yellow is minimal.
2. Step: Remove Yellow Tones – Before You Even Start Coloring 💛❌
Common causes of yellow tones:
underlying natural pigments
insufficient bleaching time
metallic residues from haircare products
silicones blocking the absorption of color
What you can do:
a silicone-free deep cleanse (e.g., anti-dandruff shampoo)
an additional light bleaching session, if necessary
pastel-prep as explained in our pastel hair guide (super helpful!)
If you skip this step, you’ll never achieve a clean grey.
3. Step: Prep Your Hair – Clean Hair, Clear Color 🫧
remove silicones
hair must be clean and dry
smooth the hair structure
1–2 washes with anti-dandruff shampoo to improve pigment absorption
4. Step: Apply Grey Skull or Allergic to Color the Right Way 🎨
Grey Skull – Color of the Month & perfect for an intense steel grey
ideal for white-blonde bases
apply generously and evenly
leave in for at least 30 minutes
heat intensifies the result
Allergic to Color – also Color of the Month & perfect for refreshing grey
nourishing grey Color Mask
ideal for a softer, elegant grey
leave in for 5–20 minutes
applied like a shampoo
Both January favorites are currently discounted – the discount is applied in the cart! 🛒
5. Step: Rinse & Care – the Finishing Touch 🌫️✨
rinse with water only
add conditioner or a light oil to the ends
low heat = longer color longevity
use Allergic to Color once per week for shine & pigment boost
🔧 What If It Still Looks Yellow?
reapply Grey Skull and leave it in longer
use Allergic to Color for a quick correction
check whether your bleaching was thorough enough
remove any remaining silicones
for persistent warmth: carefully re-lighten
🎉 Result: Cool Grey Hair That Looks Like a Salon Job – at Home!
With the right preparation, nothing stands in the way of your vegan dream grey.
