What Kind Of Menu Is Double Colour The Merits And Demerits And The Hair Colour

A double colour menu that you often hear when changing hair colour. Many people may be wondering what kind of menu it is. Due to the mechanism of double colour, it is attractive to finish the hair colour with good colouring and full of transparency. This time, we will introduce the features of double colour, advantages and disadvantages, differences in colour development, etc., together with the catalogue. At the same time, we will tell you how to minimize the damage, the treatment time, the presence or absence of self, and other basic knowledge of bleaching!

What Kind of Menu Is Double Colour?

If you’re looking for a hair colour catalogue to get new hair colour, you may come across a comment saying, “I’ll make this colour in double colour.” Double colour, as the name implies, is a two-step colouring process. Generally, it refers to a menu in which hair is bleached and then coloured with hair colour. By bleaching, the tone of the hair becomes brighter, and it is characterized by the ability to create a firm colour and transparency.

How is it different from normal hair colour?

The difference from normal hair colour lies in the number of steps. The hair colour you often hear about is one colour (single colour). The process is to put the colouring agent on the hair, leave it, wash it off with shampoo, and move on to the finish. Double colour takes two steps, from applying the medicine to washing it off. First, remove the colour of the hair with bleach, wash it off with shampoo, and then put a colouring agent on it and wash it off.

Is there a double colour without bleach?

I first mentioned “general” in the explanation of double colour because some salons do not bleach. Double colour without bleaching is a menu in which different colours are layered in two stages. Lighten the hair with the first colour and add colour with the second colour. The finished tone is darker than the double bleaching, but a solid colour characterizes it. However, double colour without bleaching is a relatively new technique, so there may be a limited number of salons available.

Advantages and Disadvantages of Double Colour

Double colour, which incorporates bleach once, has advantages that normal hair colour does not have. On the other hand, there are some disadvantages for those who care about their hair. Here, we will explain the advantages and disadvantages of double colour.

Advantages of double colour 1: Good colour development

Since the double colour is removed once and then dyed, both light and dark colours can be developed without being influenced by the colour of the ground hair. After all, the colour is good, and depending on the colour, the way the colour comes off is also wonderful. As you remove the pigment from your hair, the colour of your hair gradually becomes lighter, from black hair to brown hair to blonde hair, making it easier for you to get the original colour of your hair.

Advantage of double colour 2: High tone colour is easy to reproduce

Bleaching makes the underlying hair tone much brighter. Depending on the colour you put on it, you can achieve high tones with trendy transparency.

Advantages of double colour 3: Wider range of colour choices

As explained earlier, double colour is a hair menu that develops well and produces bright tones. That’s why. The advantage is that it is easy to incorporate subtle shades of colour that are difficult to express without bleaching and vivid colours. You can freely and beautifully add subtle shades such as ash and clear shades such as pink and red.

Disadvantages of double colour 1: High risk of damaging hair and scalp

The disadvantage of double colour is that bleaching damages your hair and scalp. You can get high-coloured hair colour like the one in the image, but bleaching strains the hair and makes it dry or thin. The drug may bleed into the skin for some people, leading to scalp damage. If the bleaching agent bleeds, the hair colouring agent also bleeds easily, so tell the hairdresser before you dye it. Recently, a bleaching agent called “care bleach” has been popular. Care bleach reduces damage to hair and scalp compared to regular bleaching agents while maintaining the quality of colour development. You can bleach with less damage to your hair and scalp, so it is recommended for those worried about hair damage who could not do double colour!

Disadvantages of double colour 2: Hair colour fades quickly

Double colour is a menu that damages hair, not a little. Therefore, there is a demerit that the colour is easier to come off than normal hair colour. For the same reason, it is a disadvantage that it is hard to apply perm. You can mitigate the damage, but you cannot completely erase it. If you want to keep the colour for a long time, it is good to calculate the colour fading and have the colour strengthened or care for the daily hair after colouring carefully.
