Hair is always a problem that leaves many concerns for women. Want to change your hairstyle and color, but need to figure out its suitability? Do you want to experience many different hair colors quickly?
The semi-permanent hair dye is a helpful solution for you to solve all the above troubles. You won’t need to spend too much time on a specific hair color. Semi-permanent hair dyes fade many times faster than permanent ones.
Our article will answer the following: How long does semi-permanent hair dye last? Let’s learn about the semi-permanent hair dye method right here.
How Long Does Semi-Permanent Hair Dye Last?
Most semi-permanent hair dyes last about 6 weeks in a user’s hair
The time it takes for the semi-permanent dye to work on your hair is short. It only lasts long enough for you to get used to the hair color and determine whether it suits you.
If you want to stick to a specific color tone, you can use permanent dyes to keep the color longer. This temporary color will likely fade as soon as you finish coloring your hair. The external influences from the environment will be the factor that accelerates its fading rate.
Experts and many users have told us that most temporary dyes disappear after 6 to 12 washes. The actual duration for each shade will depend on the hair fiber and its physicochemical properties.
What Is Semi-Permanent Hair Dye?
When you mix it with peroxide-containing additives, it creates a long-term storage chemical in your hair.
These are two chemicals that open up the hair shaft’s epidermal structures. Through this process, the colorant can penetrate deep into the hair and last longer. Many highly penetrating colors will stay in your hair permanently unless you use more potent chemicals to bleach it.
In contrast, semi-permanent hair dyes do not contain these two color-fixing chemicals. This pigment cannot penetrate deep into the hair shaft structure. It can only cling to the outside surface.
Typically, semi-permanent hair dyes will darken your hair more than your natural color. Yet, this colorant does not affect the hair’s health and naturalness. Therefore even people with weak or damaged hair can use it regularly.
Factors Affecting Semi-Permanent Hair Dye Longevity
Semi-permanent dye colors don’t last too long on your hair. Although it will fade over time, external factors will significantly affect its lifespan.
Let’s explore the factors that can reduce the temporary color fixation time chemicals perform on your hair.
The hair dye’s formula
The first thing that determines the color’s durability is the hair dye chemical’s chemical formula. Some dyes add ingredients that increase their adhesion to human hair. As a result, the hair color will last longer than other dyes.
The hair condition
If your hair is not clean before dyeing, the dye will not adhere firmly to the surface of your hair shaft.
Dandruff or dirt accumulating on your hair will prevent the dye from reaching and binding to the hair shaft. So, when you clean up the dirt afterward, the dyeing product will quickly wash off.
Plus, the natural oils that the scalp releases daily can make it harder for the dye to stick. Thus, washing your hair clean is a prerequisite for you to proceed to color your hair with semi-permanent dye.
The time you left the dye on your hair.
A dyeing procedure is also essential to prolong the chemical life. Each semi-permanent hair dye comes with detailed instructions for use. It tells you how long the dye will bond with your curls.
If you do not expose your hair to the dye for a long enough time, the chemical will not have enough time to adhere to the hair. At that time, your dyeing chemicals may not reach the level you want.
In the opposite case, if you leave the dye on your hair for too long, your hair will take longer to color.
Chemicals can stay on your hair longer than the manufacturer claims. Don’t worry because the chemical will fade and completely disappear from the hair.
Your washing habits
Ultimately, how you take care of your hair is the most critical factor in maintaining color. The shampoos, conditioners, and how often you wash your hair will determine how long the semi-permanent hair dye will last on your head.
Some shampoos contain harsh cleaning chemicals that quickly cause the dye to wash out. Fading will take place in less time if you wash your hair regularly.
In addition, the color will also fade faster if you clean your hair with hot water.
Heat will increase the chemical change and break the bond in the dye with your hair. As a result, it reduces how long the dye stays on your head.
