Hair coloring color and hair type matching test: How to choose the right hair dye color for you?

When choosing hair dye, many people encounter a similar dilemma:
they select their favorite color from the color chart but find that the result is quite different from their expectations after dyeing.

Darker colors, a dirty appearance, rapid fading, and even a noticeable decline in hair quality—these problems aren’t entirely caused by the hair dye product itself. A more common reason is that the hair coloring doesn’t match the hair type well enough.

In other words, it’s not that the color is bad, but that it doesn’t suit your hair.

Why must the color of hair dye match the hair type?

In the professional hair coloring field, there is a repeatedly verified conclusion:
the same hair dye will almost never produce the same effect on different hair types.

This is because hair coloring is not simply “coloring” but a comprehensive process involving the hair’s surface structure, internal color absorption capacity, and subsequent color-locking stability.

Ignoring hair type can lead to the following common consequences:

• The dyed color is significantly different from the packaging or color chart.
• Uneven coloring in some areas, resulting in differences in shade.
• The color-developing period of hair dye is significantly shortened.
• Hair becomes dry and dull in a short period of time

successful hair coloring is not choosing a color but understanding your own hair.

II. Four Core Dimensions for Determining Hair Type (Must Read Before Hair Coloring)

Before choosing a hair dye color, you can quickly determine your hair type by considering the following four dimensions.

1. Hair thickness: fine and soft hair vs. coarse and stiff hair

This is one of the most direct factors affecting the color development of hair dye.

Fine and soft hair

• The hair scales are thin
• Dye enters quickly
• It shows clear color development, but its stability is relatively weak.

coarse and stiff hair

• The cuticle structure is tight
• The coloring process is quite difficult.
• The color is usually darker and lasts longer.

This is why the same hair dye tends to make fine, soft hair appear “brighter,” while coarse, stiff hair tends to appear “darker.”

2. Hair volume and density: key to visual differences

Hair volume does not change the chemical reaction of hair dye, but it significantly affects the visual presentation of the color.

Thin hair:

• Dark colors tend to make the skin appear heavier.
• Low brightness will amplify the flatness.

Excessive hair volume:

• Lighter colors tend to show more dirt.
• High-contrast colors are difficult to unify in terms of gradation.

Therefore, hair volume is a variable that is often overlooked but is very practical when choosing a color.

3. Hair damage level: An invisible factor determining color stability

Damaged hair and healthy hair respond completely differently to hair dye.

Healthy hair:

• Coloring is relatively controllable
• Color close to the color chart

Damaged hair:

• Fast color absorption
• However, the colors are more prone to getting out of control and fading.

If your hair has been bleached, dyed, or permed multiple times, you need to be more conservative in your color choices, even when using high-quality hair dye.

4. Curl/Straightness: Affects color gradation and uniformity.

Straight hair:

• Hair dye shows color more clearly.
• The color difference is not obvious.

Curly hair / Naturally curly hair:

• Complex light reflection
• It easily creates a sense of depth, but it is also prone to color differences.

hair coloring with “low contrast and high blendability.”

III. Understanding the 3 Key Properties of Hair Dye Color

Before conducting a matching test, it is necessary to understand the underlying logic of hair coloring.

1. Brightness: Lightness or darkness determines the margin of error.

High brightness (light color):

• Lightweight
• High requirements for hair quality

Low brightness (dark colors):

• More secure
• More inclusive of hair types

2. Saturation: Determines whether a color is “pleasing to the eye” over time.

High saturation:

• Strong visual impact
• High risk of rollover

Low saturation:

• More natural
• More resistant to fading

3. Color temperature: Warm or cool color temperature affects the overall feel.

Cool colors:

• High sense of sophistication
• High requirements for hair quality and base color

Warm colors:

• High affinity
• More suitable for most hair types

• B. Medium
• C. More

Results reference:

Option A is the most common.
