Without Drying It Out)
If your blonde hair looks yellow, orange or dull — even though you’re using purple shampoo — you’re not alone.
Brassy blonde is one of the most common issues professionals see, and it’s often caused by over-toning, incorrect products, or lack of protection, not bad colour work.
In this guide, we’ll explain the difference between blonde and brassy hair, why brassiness happens, and how professionals keep blonde hair bright, cool and healthy using the right products and routines.
What Is Brassy Hair?
Brassy hair refers to unwanted warm tones — usually yellow, gold or orange — that appear in blonde or lightened hair over time.
This happens because:
-
Blonde hair has less natural pigment
-
Warm undertones are exposed as colour fades
-
Heat, UV exposure and minerals accelerate the process
Even the best salon blonde can turn brassy without proper maintenance.
Blonde vs Brassy Hair: The Key Difference
Professionals look at tone, shine and condition.
Healthy Blonde Hair:
-
Bright, clear tone
-
Even colour from root to ends
-
Soft, reflective shine
-
Hair feels smooth and hydrated
Brassy Blonde Hair:
-
Yellow or orange tones
-
Dull or uneven colour
-
Dry, rough texture
-
Hair feels brittle or over-processed
Correcting brassiness isn’t about stronger products — it’s about smarter care.
Why Purple Shampoo Alone Isn’t the Answer
Purple shampoo is useful — but it’s often misused.
Professionals see these common mistakes:
-
Using purple shampoo every wash
-
Leaving it on too long
-
Using it on already dry or damaged hair
This can:
-
Over-dry the hair
-
Make blonde look flat or grey
-
Cause breakage over time
Professionals alternate toning with nourishing, strengthening care.
