Commercial hair dyes have been in use for more than 110 years. Consumers now have access to an extensive range of hair dyes and lighting agents. They are free to choose the product that best addresses their given requirements.

It needs to be noted that the dyes that are now available have greatly improved when compared with their predecessors. These present-day products are easier to use and they don’t emit any foul smell, as well. Here, it won’t be inappropriate to succinctly speak about different types of hair dyes and how they work.

Temporary hair dye:
As indicated by the name, this dye colors the hair only for a short duration. To be clearer, the color will go away soon as you wash the hair once or twice. But, if you are looking for just a short-term solution, these products are the best. They act very fast in giving a new color to your hair.

If you want to immediately hide gray hair, the temporary dye won’t disappoint you. The chemicals found in these dyes have big-sized molecules, which ensure that the color doesn’t go deep inside the hair shaft. The temporary hair dyes are free of ammonia.

Semi-permanent hair dye:
When you want to give a new color to your hair without much impact on the natural color, then this product is for you. This hair dye includes small molecules that pass through the cuticle and penetrate the cortex of your hair. This color, which covers almost half the gray hairs, remains intact until about 8- 10 shampoo washes. These dyes are devoid of hydrogen peroxide and ammonia.

Demi-permanent hair dye:
We can consider this hair dye as belonging to the level after the semi-permanent variant. This is in terms of the duration for which they last. These products have only a small quantity of ammonia, and they are combined with a developer before usage.

The dye softly opens up the cuticle and then enters the shaft just to a little extent. It has to be highlighted that these kinds of dyes cannot give a new color; they are confined to improving the natural color of your hair. You can easily wash the hair 15- 20 times before the color starts to fade away.

Permanent hair dye:
This hair dye product can be treated as being the most effective one. This is about both covering the grays and lasting for a very lengthy timespan, too.

These dyes, containing peroxide as well as ammonia, fully permeate into the hair cortex. The hydrogen peroxide then makes the PPD (P- phenylenediamine) molecules undergo oxidation. Subsequently, the new color gets strongly attached to the cortex. Once the process is completed, just a small touchup has to be given to the hair once in one- and- half to two months.

Hair lightening:
Many people opt for hair lightening; bleach is the primary ingredient here. It leads to the oxidation of melanin and this process lightens the hair. Upon completion of this procedure, the hair attains a slight yellowish shade.

It’s extremely crucial to mention that not all the above hair dyes are suitable for everyone. Which is the most appropriate one is dependent on factors such as hair texture and skin health. A knowledgeable and competent professional at a quality salon can provide you with apt guidance. So do make the effort to find a good professional to help you.
