107 years ago, L’oreal (a cosmetic company in Paris) introduced the world’s first permanent hair dye. This cosmetic giant has over time supplemented and perfected and marketed many hair care and glow products. Former hair dyes that contained ammonia were replaced with new herbal dyes. The new hair colors do not contain ammonia, but with a scent and texture they remind you of the best face cream. It contains an oily component that allows harmful ammonia to be replaced by an alkaline agent (does not corrode hair and scalp). The alkaline agents contained in hair dyes lighten the hair by several tones and do not corrode it.
Oil complexes in new hair dyes enhance the effect of “replacement ammonia” and its penetration into the core of the fiber, and enhance the pigmentation and action of nourishing ingredients. Until recently, we could only buy hair dyes that did not cover the gray hair well, so our hair often seemed messy. Improving formulas and improving the technology for the production of hair dye products has made it easier for many hair salons and hairdressers. It is important that hair dyes do not contain parabens and sulfates (US brands Alterna and Aloxxi).
Using natural ammonia and oil-free salts (avocado or olive) and keratin and silk fibers, your hair is healthy and fresh. Classic aggressive colorants are not good for scalp or hair. The new oil hair dyes contain argan oil, sandalwood oil or jasmine (Keune, Garnier, Schwarzkopf, Redken, Wella). Toning colors are not for the full coverage of gray hairs, although they have 99% virgin ingredients and do not contain ammonia. Hair dyes with 97% natural ingredients contain ammonia in aerating variants (ammonia evaporates during application to the hair and no contact with the scalp). Pigments can be mixed and dosed as desired and needed to counteract unwanted reflexes (when the hair has a bluish or greenish shine). Herbal components provide complete care and recovery of hair and scalp. The new hair dyes do not contain (except ammonia) silicones or alcohol, but have a small “infusion” of medicinal ingredients. They can be used by people with sensitive scalp.
New hair coloring techniques for a natural look:
Bleeding- Works best on long hair. Three to five shades are used whose transition is almost invisible. With the darkest shade, it moves from the root of the hair which gradually turns to the brightest shade towards the tips. The effect is very natural looking because all the shades are from the same color palette. The application technique is demanding where fingers and a special sponge are used.
The bark is an important haircut technique here because the shades are arranged according to the trimmed layers. When coloring, care should be taken to comb the hair so that the hair functions when it is gathered in a bun or ponytail. The emulsion is applied before staining. It is used to trim the hairs for easier treatment. It is performed on the surface in a thinner or thicker layer depending on the desired effect.
The layered approach is the same as in the “Bark”, only implemented in multiple layers. For example, the interior moves with a dark color that turns light to the surface.
