How to deal with yellow undertones in hair

People with blonde hair – whether natural or lightened – often encounter unpleasant yellow undertones that appear over time. However, this problem affects not only blonde hair, but also white, gray, and sometimes even brown hair, which can develop brassy or orange undertones. What are the solutions for removing yellow tones and restoring natural shine?

Why does hair turn yellow?

Many people don't realize that hair yellowing affects more than just light shades. Although it's more noticeable in them, this process actually affects all hair types. The main reason is the degradation of tryptophan – an amino acid that forms molecules causing the yellow pigment.

Factors that further contribute to hair yellowing include:

• Prolonged sun exposure
• Environmental pollution
• Frequent use of heat styling tools like blow dryers and straighteners

How to remove yellow undertones from hair?

If your hair has developed unwanted yellow or orange undertones, here are some effective solutions that will restore its beautiful appearance.

Using anti-yellow products: the power of purple color

The best solution against yellow tones are specialized anti-yellow products that contain purple pigments. Why purple? This principle is based on color theory – purple is the complementary color to yellow, meaning the two colors neutralize each other.

Looking at the color wheel, it's clear that yellow and purple are opposite colors, which explains why purple pigments effectively remove yellow undertones and enhance cool tones like gray and platinum blonde.
