Some people, who do not want to change their image, set off the existing hair color by several tones. Various coloring cosmetic products are used for this, and first of all, hair dyes. Blue hair dye can contain ammonia, which destroys the hair’s protective layer. Based on this, cosmetic companies have created a line of hair dyes not containing ammonia. A distinctive feature of such dyes is their base - a gel. Gel hair dye is a cosmetic product based on a gel-like consistency that adheres perfectly to the hair, and also helps the coloring pigments to easily penetrate the hair structure. The composition of such a product includes various micronutrients: extracts of plants, herbs, flowers, various extracts, as well as vitamins and minerals. The gel base adheres well to the hair. Gel dye contains various nutrients that take care of the hairline during coloring. It is applied to dry, pre-washed hair. How to use gel dye: you need to wash your hair thoroughly and dry it, comb the hairline so that the strands of hair do not get tangled or intertwined, cover your shoulders and back with a cape, put on protective gloves, divide your hair into two parts with an even parting from the forehead to the back of the head. Initially, one half is stained, then the other, starting from the occipital part and gradually moving towards the temporal zone. Then, separate one strand at a time and apply the coloring gel with a brush along its entire length, avoiding the stained areas. Avoid getting the gel on the skin. After applying the composition to the strands, they are collected in a bundle at the back of the head and covered with polyethylene, and on top with a warm cloth. The holding time is 25-35 minutes. Then the gel dye is washed off with warm water. You can use a conditioner balm, but only when stained with permanent and semi-permanent compositions. Dry your hair with a towel and let it dry naturally. Blue hair dye has a palette: blue, azure or rich deep tones are suitable for different color types. Blue is perfect for fair-haired beauties with gray or blue eyes. The lighter the hair, the softer and more pastel the shades should be.
