Musthair expert guide
Explore color codes, undertones, and gray blending ratios in a clear way so your hair system blends seamlessly with your natural hair.
Understand the color codes
The main number indicates the depth level, ASH indicates a cool undertone, and the numbers after 1B show the gray/white hair blend.
In general, lower numbers appear darker and higher numbers appear lighter. Matching the depth of your natural hair is the first step.
Colors marked ASH reduce red, orange, and golden reflections. Compare these options if your natural hair looks muted and cool.
In the 1B05–1B80 series, the final two digits indicate the approximate gray hair percentage. Choose according to the actual ratio in the sides and back of your hair, not your age.

Accurate color matching
Comparing colors on screen is a useful starting point. For the most natural result, use one of the methods below.
Take unfiltered photos of the right, left, and back sections of your hair. Your hair should be dry, preferably photographed near a window in daylight.
Compare the color swatch beside the hair at the sides and back where the system will blend. Check it again both indoors and in daylight.
For the most precise comparison, our experts can assess an untreated hair sample taken from the side or back area.
Do not compare depth alone. Consider the undertone, gray ratio, and appearance in daylight together. Matching the hair system to the hair at the sides and back is more accurate than using the color on top as your reference.
Frequently asked questions
Review the most common questions before making your decision.
All three belong to the black family, but they differ in intensity and natural reflection. If your hair shows brown tones in daylight, compare #1B. If it appears very deep and clearly black, compare #1 or #1A.
ASH indicates a cooler, muted undertone with fewer warm, red, or orange reflections. The Musthair color range includes #4ASH and #7ASH.
No. Choose according to the current gray/white hair ratio at the sides and back. People of the same age can have very different levels of graying.
Not always. Display settings, brightness, night mode, camera processing, and ambient light can alter the shade. Images are for guidance; a physical comparison is more reliable for the final choice.
Yes, if your hair is consistently dyed the same shade. However, consider fading and root regrowth. Whenever possible, choose based on the shade you intend to maintain long term.
Send photos of the sides and back of your hair taken in natural light, and Musthair experts will help assess the closest options.
