Difference Between Semi And Permanent Hair Dye
Table of Contents
No matter your hair type, you might have wondered about the difference between semi and permanent hair dye at some point. Which one is right for you? While there is no simple answer, understanding a little bit about each can help. So let’s look at the difference between semi and permanent hair dye.
What is semi-permanent hair dye?
Semi-permanent hair dye is a type of hair color that doesn’t penetrate the hair shaft deeply and only coats the outermost layer of the hair. It usually lasts between 4-6 weeks and gradually fades with each wash. Semi-permanent hair dye doesn’t contain ammonia or a developer, and it typically comes in a variety of shades. This type of hair dye is a good option for those who want to experiment with new hair colors without committing to a long-term change.
What is permanent hair dye?
Permanent hair dye is a hair color that lasts until the hair is cut off. It usually doesn’t fade out evenly and can leave the hair looking unnatural. Permanent hair dye is a more serious commitment. It also has a more pungent smell than semi-permanent dyes.
Main differences between semi-permanent and permanent hair dye
Here are some main differences between semi-permanent and permanent hair dye.
Permanent hair dye lasts much longer than semi-permanent hair dye, typically around 4-6 weeks for semi-permanent and up to 8 weeks or more for permanent.
Permanent hair dye penetrates the hair shaft and changes the hair color from the inside out, while semi-permanent hair dye only coats the outer layer of the hair and doesn’t penetrate as deeply.
Permanent hair dye usually offers a wider range of color options, while semi-permanent hair dye is limited to more natural-looking shades.
Permanent hair dye contains harsh chemicals such as ammonia and a developer, which can be damaging to the hair over time, while semi-permanent hair dye doesn’t contain these chemicals and is gentler on the hair.
Permanent hair dye provides better gray coverage than semi-permanent hair dye, which is more suited for adding a subtle tint or color refreshment.
Semi-permanent hair dye fades gradually with each wash, while permanent hair dye may result in visible roots as the hair grows out.
How Do You Know Which Type Of Hair Dye To Use?
If you’re unsure which type to choose, you should consider a few things.
- First, think about how often you want to color your hair. Permanent dye is the way to go if you want a long-term commitment. If you’re not ready to commit or want to try a new color for a while, semi-permanent is a good option.
- Second, consider the level of maintenance you’re willing to deal with. Permanent color requires more upkeep than semi-permanent, as it can start to look faded and dull after a while. If you’re unwilling to touch up your paint regularly, semi-permanent may be a better choice.
- Finally, think about the health of your hair. Permanent color involves lifting the hair shaft’s cuticle to deposit pigment, damaging your hair. Semi-permanent color doesn’t require this step, so it’s generally gentler on your hair.
- When choosing a hair color, it’s essential to consider your own needs and preferences. With a bit of thought, you can find the perfect shade.
Benefits Of Using Semi-Permanent Hair Dye
- Semi-permanent hair dye is gentler on hair than other dyes.
- It doesn’t contain ammonia and doesn’t damage the hair as much as other dyes.
- This is because semi-permanent hair dye doesn’t penetrate the hair shaft as much as other dyes.
- This makes it a good option for those with damaged hair or who want to change their hair color often.
How Long Does Semi-Permanent Hair Dye Last?
Semi-permanent hair dye is a type of hair coloring applied to the hair shafts and lasts for a long time. It typically lasts around four to six weeks, but the length will depend on a few factors, such as how often you shampoo your hair and how much sun exposure it gets.
The dye will gradually fade over several weeks or months and eventually wash out thoroughly.
Risks Associated With Using Semi-Permanent Hair Dye?
Like all types of hair dye, some risks are associated with using semi-permanent dye. Here are some of the possible dangers:
- Hair color may not turn out exactly as expected. This is because the semi-permanent dye is not as permanent as other hair dyes so it may fade or change over time.
- The color may not be consistent throughout the whole head of the hair. This is because different sections of your hair may take the dye differently. The paint may cause your scalp to become dry and itchy.
- The dye may cause your hair to fall out more quickly than usual.
- If you are allergic to any of the ingredients in the dye, you may experience adverse effects like skin irritation or an itchy scalp.
- If pregnant or breastfeeding, you should avoid using semi-permanent hair dye, as its ingredients may harm your baby.
- If you have previously experienced an adverse reaction to hair dye, you should avoid using semi-permanent hair dye, as you may experience a similar response.
How To Apply Semi-Permanent Hair Dye Properly?
When applying semi-permanent hair dye, it’s essential to follow the instructions on the box carefully.
- First, start with clean, dry hair. Wetting your hair before dyeing it can cause the color to come out unevenly.
- Next, put on gloves to protect your hands from staining.
- Using the applicator bottle provided, apply the dye evenly throughout your hair. Once all of your hair is coated, leave the dye in for the amount of time specified on the box.
- Finally, rinse out the dye with cold water and shampoo as usual.
By following these simple steps, you can ensure that your semi-permanent hair color will look great and last several weeks.
The Choice Is Yours
There are a variety of semi and permanent hair dye options on the market, so the best one for you depends on your individual needs and preferences. Some people prefer semi-permanent dyes because they are less damaging to the hair than permanent dyes, while others prefer the more intense color options that permanent stains offer. Ultimately, it is up to you to decide which option is best for you.

Can you mix semi-permanent and permanent hair dye?
It is not recommended to mix the two types of dye, as they have different formulations and can interact unpredictably. If you want to switch from one type of dye to the other, it is best to wait until the previous dye has completely faded or grown out.
