Is Permanent Hair Dye Really Permanent


Permanent hair dye is a type of hair color that uses an ammonia-based solution to open the hair cuticle and deposit color into the cortex of the hair. The color is then “set” with a heat process. This type of hair color is also known as “oxidative hair color” because it uses oxygen to develop the color.

Permanent hair color can last anywhere from four to eight weeks, and sometimes longer, depending on the quality of the hair color and how well it is maintained.

Permanent hair dye is a great way to change your look without having to worry about your color fading. However, there are some things you should know about permanent hair dye before you use it. First, it is important to understand that permanent hair dye is not actually permanent.

It will slowly fade over time, so you will need to touch up your color every few months to keep it looking its best. Additionally, permanent hair dye can be damaging to your hair if it is not used correctly. Be sure to follow the instructions on the packaging and use a good quality hair dye to avoid damaging your hair.

How Long Does Permanent Hair Dye Last

When it comes to hair dye, there is no such thing as “permanent.” While some hair dyes claim to be permanent, they will eventually fade. The length of time a permanent hair dye will last depends on a number of factors, including the quality of the dye, how often it is exposed to sunlight, and how often it is shampooed.

In general, however, permanent hair dyes will last anywhere from four to six weeks. After that, the color will start to fade and will need to be reapplied.
