3 Tips When Dyeing Your Hair Blue from the experts at GDY

Dreaming of Going Blue? Here’s What the Experts at GDY Want You to Know

If you’ve been dreaming of bold, electric blue hair—or have tried it before with mixed results—you’re not alone. Blue is one of the most iconic and expressive hair colors out there, but it can also be one of the most challenging to get just right.

Check out these tips to get the blue of your dreams!

Tip #1: Level of Lift Is Everything

This is probably the most important step when working with semi-permanent dyes—especially shades like blue. To get a bright, vivid result, your hair needs to be lifted to the lightest level possible, ideally a pale platinum blonde.

Why? Because blue pigment reacts to whatever undertone is left in your hair:

• Blue + yellow = green
• Blue + orange = muddy

Lifting your hair to a clean, cool base prevents those unexpected tones and helps your blue come through bold and bright.

Tip #2: Pre-Tone with Platinum DYEposit

Once your hair is lifted, toning is essential—and that’s where Platinum DYEposit comes in.

This toning deep conditioner is formulated with a blue-violet base to neutralize yellow and orange undertones that could interfere with your final color. It helps create a clean, cool-toned canvas that allows your blue hair dye to show up exactly as intended.

Bonus: It also nourishes your hair post-lightening, so you're not only prepping for color but giving your strands some TLC at the same time.

Tip #3: Even Saturation = Even Color

One of the most common mistakes when dyeing hair at home? Rushing the application.

Take the time to pre-section your hair before you start. Working in thin sections helps ensure even saturation, especially with semi-permanent colors like blue. Applying dye too quickly or too thickly can lead to blotchy or patchy areas, where some strands pick up more pigment than others.

Ready to Go Blue?

Armed with these three expert tips—proper lift, effective pre-toning, and careful application—you’re set up for success. Whether you’re going for pastel denim or bold navy, following these steps will help you achieve a consistent, vibrant blue that actually lasts.
