Hair coloring is one of the main parts of the work on your style.
Thinking about new hair color ideas?
Properly selected color, along with a haircut, revitalizes all the style, brings a touch of personality to it, and allows you to change at any time. The color dye can be different. Everyone knows that hair color is permanent and non-permanent.
But here is the main difference between permanent hair color from all other colors and what semi permanent hair dye is!
How long does permanent hair color last?
Permanent color means permanent.
Of course, there is no hair color that will ever change the color of your hair, so this term is used for the most persistent type of dye.
The basis of such dyes is ammonia, or its analog, a substance that allows the dye composition to penetrate deep into the structure of the hair and replace the existing color pigment with a new one.
In this case, the bonds between the molecules inside the hair are destroyed, and then new ones are built – it is due to this that the permanent hair color lasts so long.
How the permanent hair dye works?
Ammonia or ammonium hydroxide acts aggressively on the hair: it raises the scales of the hair, passing the coloring composition inside.
There are a chemical reaction of ammonia with hydrogen peroxide takes place, due to which the hair swells, and its natural color pigment is completely destroyed and replaced by pigment from paint.
Permanent coloring Precautions
Ammonia is incredibly volatile – that is why we all can smell permanent hair dye while visiting a salon or while dying at home, in the most exceptional cases, ammonia fumes can even cause an allergic reaction.
Therefore, in order not to get a headache, it is recommended to paint in a well-ventilated room – this also applies to cases of permanent dyeing at home, and when dyeing in beauty salons.
The composition of permanent hair dye, of course, irritates the skin of your head. However, you should check if you are allergic to one of the components of the dye.
To do this, apply the composition to a free area of the skin and wait for a quarter of an hour: if redness or itching occurs, it is better to refuse permanent dye with this composition.
