Try dying your hair if you want to give your look a complete makeover. Semi-permanent hair color is the ideal solution if you are unsure which color to choose or don’t want to commit to it for a long time.

Semi-permanent dye eventually fades with repeated washings. So, you can wash the color out of your hair if you have an odd case of hair color gone wrong. But it still lasts several weeks. Those just diving into the world of hair dyes will find this a dream come true. This temporary hair color is a safe and fun way to browse the different shades until you find your favorite one.

Additionally, applying semi-permanent hair dye takes less time, effort, and money than permanent hair dye. Take a look at the basics of this popular hair coloring technique. Scroll down.

What Is Semi-Permanent Hair Color?

Semi-permanent hair color is perfect for anyone who wants a short-term makeover for their hair. Let us see how this type of hair color differs from its traditional counterpart:

  • It coats the hair shafts instead of penetrating into the hair cortex.
  • It is gentler and less damaging for the hair as it does not contain ammonia or hydrogen peroxide.
  • It lasts for a shorter time (usually about 8 washes).
  • It can be applied directly to the hair without any developer.

We have looked at what semi-permanent hair color entails. Now, let us move on to understand how safe this hair treatment is in terms of application.

When it comes to semi-permanent hair dye, it is safer and less damaging than permanent hair color. This hair color’s formula does not contain any bleach or ammonia. So even if your hair has been chemically treated previously, going for a semi-permanent hair dye is a safer bet than opting for permanent hair dyes. How long does semi-permanent hair dye last? Check out the next section to know more.

Charlotte, a beauty blogger, shares her semi-permanent hair dye experience that required multiple sessions until she achieved the color she desired. “My hair surprisingly still feels pretty much the same as it did before the 5 dyeing process. It’s possibly the slightest bit more dry but really not that much. There was no breakage, no hair fell out, it’s honestly fine (i),” she claims. She also points out that though semi-permanent dyes are comparatively less damaging, they still have chemicals in them and hence, one must treat their hair by exercising their own discretion.

How Long Does Semi-Permanent Hair Dye Last?

Typically, it has been seen that semi-permanent hair color lasts for about 8 washes. In fact, it has been seen that users end up enjoying the best version of the temporary dye within the first 2 weeks of application.

Note that the duration of the color also depends on your hair porosity. The higher the porosity of your hair, the quicker the color will fade away. It is also worth mentioning that the hair products you use, like shampoo and conditioner, should be safe for color-treated hair to prevent the color from washing off too quickly.

Avoid applying harsh chemicals to your color-treated hair and shampooing it frequently to prevent the color from fading away soon.

Now, let’s explore the difference between semi- and demi-permanent hair color in the following section.

What Is The Difference Between Semi- And Demi-Permanent Hair Color?

Semi-permanent and demi-permanent hair colors differ mainly in their longevity and penetration into the hair shaft. Semi-permanent dyes do not contain ammonia or developer and merely coat the hair’s outer layer. They last through a few shampoos and gradually fade, making them ideal for temporary color changes or enhancing natural tone of your hair. In contrast, demi-permanent hair colors contain a low-volume developer, allowing them to penetrate the hair shaft slightly. They last longer, typically through 20-24 shampoos, and can provide more noticeable color changes. While both options are less damaging than permanent dyes, demi-permanent colors offer a bit more durability and color variation.

In the next section, we will learn more about the different types of hair dyes available at your disposal and how they differ from each other.

The ABC Of Using Semi-Permanent Hair Color

A. How To Apply Semi-Permanent Hair Color

Applying semi-permanent hair color at home involves a four-step process:

Step 1: Run Through The Equipment Checklist

Before you buy hair color, check if the kit has everything you need, such as:

  • A tube of color
  • Gloves
  • An instruction manual
  • A brush

As a precautionary move, make sure to do a patch test 48 hours prior to each use. This will help you figure out if you are allergic to that dye.

Step 2: Get Your Hair Ready For The Color Application

Next, you need to prep your hair by shampooing and conditioning it. Make sure to dry your hair completely before you apply the hair dye. You can either wait for your hair to air-dry your hair or use a blow dryer.

Step 3: Apply The Hair Dye

  • Once your hair is ready to color, go through the instruction manual to understand how you should apply it.
  • Put on your gloves.
  • Divide your hair into 3-4-inch sections, using sectioning clips to hold them in place.
  • Start applying the semi-permanent hair color section-wise, from root to tip.
  • Leave the color on for the duration mentioned in the instructions. Typically, you need to leave the dye on your hair strands for about 15-30 minutes.
  • Wash off the dye with a color-safe shampoo.

Step 4: Post-Color Hair Maintenance

Granted that the color will gradually fade away by the eighth wash, but you can still prolong the hair color by taking good care of your hair. So make sure to follow a dedicated hair care routine as outlined below:

  • Go For A Color-Safe Shampoo And Conditioner

It is important to opt for a color-safe shampoo and conditioner to keep your locks looking healthy and shiny. You can also use a deep conditioner or a hair mask 1-2 times a week to deeply nourish and moisturize your hair.

Finally, use a color-protecting primer after washing your hair. It will ensure that your hair color does not fade away due to any kind of heat styling or excessive sun exposure.

  • Use Lukewarm Water Instead Of Hot Water

Hot water is not good for your hair and skin. For starters, it can dry out the scalp and rid your hair of its natural oils. Heat makes the cuticle lift, and that is bad for the color. Eventually, you will notice your strands drying out and the color fading wash by wash. Therefore, it is recommended to wash your hair with lukewarm or cold water for the best results.

  • Let Your Hair Air-Dry

It is common knowledge that blow-drying your hair too often can make it dry and brittle. Hence, it is always better to let your hair air-dry naturally. It will help retain your hair’s natural texture while ensuring that your hair color lasts longer.

  • Limit Sun And Chlorine Exposure

In addition to following the above-mentioned tips, remember to limit your hair’s exposure to the sun. To do so, you can wear a hat or a headscarf when you step out. It is also recommended that you avoid swimming pools as chlorine can cause discoloration and add a green tinge to your hair.

The cuticle layer may take approximately 72 hours to absorb the hair dye completely, Therefore, avoid washing before that to retain the color well.

B. How To Remove Semi-Permanent Hair Color

Removing semi-permanent hair color is a simple process. All you need to do is wash your hair frequently as the color fades away naturally. Alternatively, you can try using a semi-permanent hair color remover. However, remember that the dye may not fade completely, and your hair may not return to its original color.

Now, let’s talk about how semi-permanent hair color affects your hair.
