Our helpful shade charts showcase every level and possible tone that we offer. Combining the level number with your desired tone will give you your ideal color shade.

Transmission oflight

Standing in natural light, grab a section of hair, as far back at the crown as you can hold up and actually see. Hold it up and away from the rest. You want the most accurate match, and hair tends to look darker when layered against other hair. The crown is critical. If you look at the roots along your hairline, you might be fooled into thinking your level is lighter than it is because of sun exposure.

Now that we’ve established the basics of hair color levels, it’s time to determine which hair color level you want to achieve with the help of Zotos Professional hair color and lightening products.

Tones range from warm to cool and are represented by the letters you see on the packaging. They are what give a hair color its overall shade characteristic. They are designated by the letters that appear next to the number/level. The dominant tone will be the first letter, the secondary tone is the second letter, and some have a tertiary (just a hint of a tone), which is the third letter.

Goal: Go Lighter:  It’s best to choose a shade that’s relatively close to your natural/starting level if brassy/warm tones aren’t desired. (within 2 levels). However, if you fall within natural/starting levels 6 or lighter (and gray coverage is 25% or less), you can use AGEbeautiful®'s High Lift Ultra Blonde Shade that lifts up to 4 levels. Any lighter than that, turn to a lightener like AGEbeautiful® Ultra Bond™ to do the job.

For example, A level 3 natural level desires a level 5 is light brown. When going lighter, warm tones (or an underlying pigment, if you want to use the professional term) are exposed during processing. So, you’d want to choose either enhance the warm tones with a shade like 5G (Gold) or neutralize it with a cool-tone shade like 5A (Ash)

While we believe that anyone can achieve salon-worthy results at home, when it comes to hair color, there are a couple of essential details to nail out before you even begin mixing your dye. Even if you already have a particular hue in mind, you should identify your hair color level before making a final decision. It’s one of the reasons why we ask you this question in our color quiz. What level is my hair color, you ask? Don’t stress. We’ve got pro tips to help you figure it out.

When studying a photosynthetic organism, scientists can determine the types of pigments present by using a spectrophotometer. These instruments can differentiate which wavelengths of light a substance can absorb. Spectrophotometers measure transmitted light and compute its absorption. By extracting pigments from leaves and placing these samples into a spectrophotometer, scientists can identify which wavelengths of light an organism can absorb.

Goal: Go Darker: We recommend only going one shade darker at a time. Gradually coloring a deeper hue will help you adjust to your new shade.

If using AGEbeautiful® High Lift Ultra Blonde Shade: Mix your color with 40 volume developer if gray coverage is not a concern.

You can find out your natural level by matching a root area of your crown, a section that hasn’t been colored (often called re-growth), to one of the swatches on the natural level scale (shown below) Here are some tips from the Pro’s to ensure you determine it correctly:

The visible light seen by humans as the color white light actually exists in a rainbow of colors in the electromagnetic spectrum, with violet and blue having shorter wavelengths and, thus, higher energy. At the other end of the spectrum, toward red, the wavelengths are longer and have lower energy.

Knowing the level of your natural hair color, or what we colorists refer to as your starting level, is important because it contributes to your final result. Bottom line - it’s important to know where you are starting - so you can select a shade in a level that is achievable for you.

As with levels, it’s helpful to determine how much gray you have and put it into terms of a percentage. See below for visual examples of different percentages of gray. This is important because certain hair color shades will have tips or directions to ensure optimal gray coverage and/or will let you know if they aren’t designed for high percentages of gray.

If you are going lighter than your natural level, warm tones will occur on their own. You can choose to enhance/bring out more “warmth” by selecting a warm shade OR counteract/tone down expected warm/brassy tones by selecting a “cool” shade in your desired level.

Chlorophylls and carotenoids are the two major classes of photosynthetic pigments found in plants and algae; each class has multiple types of pigment molecules. There are five major chlorophylls: a, b, c and d, along with a related molecule found in prokaryotes called bacteriochlorophyll.

Many photosynthetic organisms have a mixture of pigments. In this way organisms can absorb energy from a wider range of wavelengths. Not all photosynthetic organisms have full access to sunlight. Some organisms grow underwater where light intensity and quality decrease and change with depth. Other organisms grow in competition for light. Plants on the rainforest floor must be able to absorb any light that comes through because the taller trees absorb most of the sunlight and scatter the remaining solar radiation

What does it mean toabsorb light

Different kinds of pigments exist, each of which has evolved to absorb only certain wavelengths or colors of visible light. Pigments reflect or transmit the wavelengths they cannot absorb, making them appear in the corresponding color.

Your hair color level refers to how light or dark your shade is, regardless of tone. Pros use a universal level system to standardize a brand’s hair color charts to prevent blurred lines — “medium blonde” could mean different things to different people. In order to pick the perfect shade, it’s important to understand the level system manufacturers use to communicate this information. Hair color levels typically range from 1 to 10, with 1 being the darkest (black) and 10 being the lightest (lightest blonde). This “level” appears on the hair color box, so you know how dark or light your final result will be.

When coloring high percentages of gray (50% or more), a shade with some Neutral should be chosen like our Age Beautiful (™) NNG or NNV collections, or intermixed with vibrant tones such as  B (Blue), V (Violet), R (Red) or RR (Red Red) in the same level to ensure a vibrant color plus complete gray coverage without unwanted “off tones” (example 1 oz 5N + 1 oz 5RR mixed with 2 oz 20 volume developer).

Goal: Match Your Color Level: If you are looking to match and enhance your natural level, choose a level one level lighter. If you aren’t certain, it’s always best to err on the lighter side (it’s much easier to go back in and color deeper than to lighten color that you feel is too dark).

What happens whenlightis absorbed

Light energy initiates the process of photosynthesis when pigments absorb the light. Organic pigments have a narrow range of energy levels that they can absorb. Energy levels lower than those represented by red light are insufficient to raise an orbital electron to an excited, or quantum, state. Energy levels higher than those in blue light will physically tear the molecules apart, a process called bleaching. For example, retinal pigments can only “see” (absorb) 700 nm to 400 nm light; this is visible light. For the same reasons, plant pigment molecules absorb only light in the wavelength range of 700 nm to 400 nm; plant physiologists refer to this range for plants as photosynthetically-active radiation.

If you see a lot of grays, do your best to decipher any color you can. Remember that our hair typically changes as we age, so those blonde curls you had as a child aren’t an accurate representation of your current shade. Next, determine which one of these hair color levels is closest.

Warm tones appear lighter and brighter and fall under Red/Copper/Gold (includes WB/Warm Beige).  Cool tones appear darker to the eye and are often referred to as Ash/Violet (includes Blue, Mahogany).

Neutral is neither warm nor cool. It is an ideal tone to choose to ensure complete gray coverage and to prevent off/unwanted tones when covering high percentages of gray.

Each type of pigment can be identified by the specific pattern of wavelengths it absorbs from visible light, which is the absorption spectrum. Chlorophyll a absorbs light in the blue-violet region, while chlorophyll b absorbs red-blue light. Neither a or b absorb green light; because green is reflected or transmitted, chlorophyll appears green. Carotenoids absorb light in the blue-green and violet region and reflect the longer yellow, red, and orange wavelengths.

With dozens of different forms, carotenoids are a much larger group of pigments. The carotenoids found in fruit, such as the red of tomato (lycopene), the yellow of corn seeds (zeaxanthin), or the orange of an orange peel (β-carotene), are used to attract seed-dispersing organisms. In photosynthesis, carotenoids function as photosynthetic pigments that are very efficient molecules for the disposal of excess energy. When a leaf is exposed to full sun, the light-dependent reactions are required to process an enormous amount of energy; if that energy is not handled properly, it can do significant damage. Therefore, many carotenoids are stored in the thylakoid membrane to absorb excess energy and safely release that energy as heat.
