The colorist analyzes mistakes in coloring

Results from coloring your hair at home or even in a salon can occasionally fall short of your expectations. Uneven tones, incorrect shade selection, and post-coloring hair damage are all common coloring errors—unlike what you might believe.

Professional colorists are able to identify these mistakes immediately. Numerous things can go wrong when coloring, such as selecting the incorrect color for your skin tone or estimating incorrectly how long the dye will take to process.

This post explains the most common coloring errors and provides suggestions for what might have gone wrong. You can achieve the ideal color every time by being aware of these problems and being better prepared to avoid them.

The professional examination of typical coloring errors by a colorist can help people steer clear of problems like uneven tones, damaged hair, and unanticipated outcomes. Anyone can achieve better, healthier, and more vibrant color results by knowing what goes wrong, like using the wrong developer, applying color on damaged hair, or ignoring undertones.

Error 1. Unwanted redness appeared on dark colored hair

Cold hues are advised for people who dislike deep tones with a reddish undertone. However, colder hues always appear darker than their warm-toned counterparts. This is due to the fact that "cold" demands more pigment, and the darker the shade, the more pigment needed.

A hairdresser can use Igora Royal E-1 Sandre concentrate with a 3% oxidizer if a client requests that the red undertone be removed from dark hair. We dye it pure, and it covers every warm shade in the spectrum, including orange and red. However, it will always make a color one tone darker, so unless you have the requisite coloristics knowledge, it is best not to use it on your own.

Using dyes that already contain cold pigments is the second option. Only 3% oxidizer should be used; any higher percentage will lighten the hair a little bit and add extra warm tones.

Error 2. An unpleasant greenish tint has been obtained. How can I remove this “green” now

The coloring mixture most likely lacked sufficient warm pigments. More precisely, the green ought to have obscured the red. It is preferable to use pre-made shades that already have a subdued red pigment (such as chocolate) so as to avoid going too red. They are identified in Schwarzkopf Professional by the number 6 following the hyphen. However, the cold light lamps could also be to blame. Beige, natural, and cold-toned hair tones can appear green under such lighting. Neutral light bulbs are typically utilized in salons to avoid warping the color achieved through coloring.

Error 3. The hair color becomes darker and darker, even if the length is colored much less often than the roots

All because we repeatedly break the technology when coloring. For instance, we use a permanent dye with a high pigment content for the roots that can be used to paint over gray hair. Whether intentionally or inadvertently, we consider it insignificant when we stray 1-2 centimeters beyond the line of the regrown roots because the dye ends up on the previously colored hair. Subsequently, the length acquires an extraneous hue. This region’s color gets darker than is necessary. The cycle repeats itself with every new dye job; the hair regrows and now the entire length is double-pigmented.

It is imperative that the dye is exclusively applied to the root zone and not to the previously dyed length. The dyeing guidelines state that one dye is used for the root zone and a different dye—such as a semi-permanent or semi-permanent, more transparent or lighter shade—is used to restore the color along the length. Dual is the name given to this dyeing method.

Error 4. The roots “glow” after dyeing

This occurs as a result of the root zone’s slight lighter color than the hair’s overall length. If you were to lighten natural light brown hair, for instance, you would notice that the area of hair closest to the scalp is about 1 centimeter lighter than the canvas. This particular hair section’s natural coloring pigment has just begun to form, is more sensitive to the lightening mixture, and is not yet as firmly fixed. In this context, the master was instructed to apply dye or clarifying powder by length, backing away from the roots by one to 1.5 centimeters. and only after that should you start lighting the roots.

The same thing happens when initially dyeing natural hair in bright shades. If the hairdresser applies the dye to the entire length at once, then the area of ​​hair at the roots will be brighter and more saturated. And here the hairdresser should also start dyeing from the length of the hair and only then move on to the root zone. But you can do it this way: take a 6% oxidizer for the length, and 3% for the root zone, then the dye can be applied first to the roots, and then to the length.
You can correct the situation with the light root zone by re-dyeing it, but take a dye half a tone or tone darker and a small percentage of oxidizer.

Error 5. Spoiled hair after toning bleached blonde with a low % oxidizer using Schwarzkopf Igora Royal dye level 10

Levels 10, 11, and 12 dyes are lightening dyes; they contain the bare minimum of pigment to produce a shade. Use oxidizers with high percentages, 9 and 12. Their chemical composition is made to effectively penetrate the hair, open it up, lighten it significantly, and slightly tone it. In one step, color your hair blonde, toning and lightening it at the same time.

Level 10–12 lightening dyes will remain lightening even if you combine them with a small percentage of oxidizer. Such dyes will only make hair more porous and fragile if applied to previously lightened, highly porous hair. It is preferable to use a shade such as Igora Royal 9.5 for toning bleached hair. It’s merely a shade. Schwarzkopf only marks toning shades in the palette with the letter T; lightening and toning shades are marked with the letter L.

Error 6. Confusing bleaching and lightening

These are different procedures, they differ both in the tool of action and in the possible result. Bleaching is performed with dye only on natural hair, and bleaching is done with powder on both natural and previously dyed hair. The dye lightens with high % oxidizer – 9 and 12. The powder is used only with small % oxidizer – 3 and 6.
When lightening with dye, we can make hair lighter by 3-5 tones (the maximum you can get is level 12), and when bleaching – by 7-9 tones (level 18 is completely white hair). The dye works on a base of at least level 6, that is, you can only lighten hair of level 6 and lighter. Powder can bleach any base.

Anyone can make coloring errors, but the first step in correcting them is realizing what went wrong. With more planning and knowledge, mistakes like selecting the incorrect shade, over-processing hair, or failing to consider hair type can be prevented.

You may get the results you want without harming your hair by paying attention to the needs of your hair and seeking professional advice when in doubt. Maintaining the health and vibrancy of your hair can be greatly enhanced by paying attention to the advice of a professional colorist.

Recall that hair coloring involves both personal hygiene and technique. When done properly, it improves your appearance and gives you more self-assurance. A little guidance and attention to detail will allow you to enjoy a beautiful color free of errors.
