How long does semi-permanent hair dye last?

If you're considering dyeing your hair, you probably want to know how long semi-permanent hair dye will last. While semi-permanent dye does not last as long as a permanent dye, it can still give you vibrant color for weeks or even months. As part of this article, I'll share my own experiences with semi-permanent hair dye, as well as some tips for making it last as long as possible.

So, how long does it actually last on hair? That depends on a few factors, including the brand and formula I use, the condition of my hair, and how well I take care of it. With the right care and maintenance, I can extend the life of my semi-permanent hair dye. I will share tips below on how to prolong the life of your color and how to properly take care of your color-treated hair to keep it vibrant and healthy.

How long does semi-permanent hair dye last?

It typically lasts between 4 and 12 washes, depending on the specific product and your hair type. Your hair's condition, how well you care for it, and the dye brand and formula will all influence how long it takes to fade. From personal experience, I can say that this period is about 6 weeks. This can be your starting point because I always apply the dye to the same hair and use the same dye. Moreover, I wash my hair 2-3 times a week and use the same hair care products. That includes dry shampoo, a leave-in conditioner, and a hair mask.

The color will fade after a few weeks, with the fading process accelerating as you wash your hair and expose it to sunlight. Maintaining your color properly will extend its lifespan and keep it vibrant for a longer period of time.

What is semi-permanent hair color?

It's a temporary dye that adds color to the hair. In contrast to permanent hair color, semi-permanent hair color deposits color pigments on the outside of the hair shaft, rather than altering the hair structure. Therefore, the product does not lighten the hair nor does it contain ammonia or bleach. Typically, semi-permanent hair color fades over time, typically after 4 to 12 washes. It is a good choice for people who want to experiment with color without committing to a permanent change. There are also some semi-permanent hair dyes that contain conditioning agents to help nourish and moisturize the hair.

How did I find out about it?

One day, I was browsing the hair dye aisle at the drugstore, trying to decide which color to choose. I had always been hesitant to try permanent hair color because I was afraid of the chemicals and the commitment. But as I scanned the shelves, I noticed something called "semi-permanent hair color."

Intrigued, I picked up the box and read the label. It said that the dye would gradually fade over time and didn't contain any harsh chemicals like ammonia or bleach. I was sold! I chose a bold purple shade and headed to the checkout.

At home, I followed the instructions on the box and applied the dye to my hair. I was pleasantly surprised by the results. The color was vibrant and beautiful, and my hair felt soft and healthy. Best of all, I knew that the color would eventually fade, so I wasn't stuck with it forever if I changed my mind.

From that day on, I became a fan of semi-permanent hair color. It allowed me to experiment with different shades and styles without the commitment of permanent dye. And as it turns out, it was just the thing I needed to help me find my true hair identity.

What are the benefits of semi-permanent hair dye?

Semi-permanent hair dye has several benefits:

• It's easier to use: Unlike permanent dye, it does not require special mixing or processing.

• It's less damaging to the hair: The product does not contain ammonia or bleach, so it is generally less damaging.

• It's more affordable: Many people prefer semi-permanent hair dye because it is cheaper than permanent dye.

• It's less permanent: It's a good solution for those who aren't sure about hair colors or want to experiment with a different shade but don't want to commit to permanent changes. After 4 to 12 washes, it will gradually fade.

• It's more versatile: This type of dye lets you experiment with a variety of shades and styles without committing permanently.

What is the difference between semi-permanent and permanent hair dye?

It is the method of coloring the hair that makes semi-permanent hair dye different from permanent hair dye. Using chemicals like ammonia and bleach, permanent hair color alters the hair's structure to change color permanently. To maintain the color, periodic touch-ups are required until the hair grows out or is cut off.

On the other hand, semi-permanent hair color does not contain ammonia or bleach. It simply coats the outside of the hair shaft, depositing color pigments. Thus, it prevents hair from lightening and harms it less. After a few washes, it gradually fades. People who want to experiment with color without making permanent commitments should consider this option.

Do you need special skills to apply it?

Applying semi-permanent hair dye is generally easier than applying permanent hair dye because it does not require special mixing or processing. Dyeing my hair for the first time was a relatively easy and enjoyable experience. According to the product label, I applied the dye to my hair starting at the roots and working my way down. After letting the dye process for the recommended amount of time, I rinsed it with cool water.

SHORT ANSWER: No, you don't need any skills to use semi-permanent hair color.

I also noticed that my hair felt softer and smoother after using the semi-permanent dye, likely due to the conditioning agents in the formula. Overall, I was very satisfied with the experience and it was simple as that:

How to apply semi-permanent hair color

• Protect your clothing and skin: Wear an old shirt and apply petroleum jelly (or vaseline) around your hairline to keep your skin stain-free.

• Section your hair: Use clips to separate your hair into sections so you can apply the dye evenly.

• Apply the dye: Start at the roots and work your way down to the ends, following the instructions on the product label.

• Process the dye: Allow the dye to process according to the instructions on the product label. You will usually have to leave the dye in your hair for a certain period of time before rinsing it out.

• Rinse and style your hair: Once your hair has been dyed, rinse it out with cold water and style it as you wish.

How to remove semi-permanent hair color at home

Here are a few methods for removing semi-permanent hair color at home:

• Wait it out: Instead of using harsh chemicals or products, you can let the color fade naturally. While it will take some time, it is the safest option for your colored hair.

• Baking soda and dish soap: Combine equal parts baking soda and dish soap. Make a paste of the ingredients and apply it to your hair, allowing it to sit for a few minutes before rinsing it out. Although this method may lighten the color, it can also dry out the hair, so you should follow it up with a deep conditioning treatment.

• Shampoo: The best way to lift some dye out is to use a shampoo that helps clarify the colored hair or one that is specifically formulated for removing hair color. While this method may not completely eliminate the color, it may fade it to a certain extent.

• Lemon juice: Since lemon juice is a natural bleaching agent, it can lighten your hair color. You can apply lemon juice and water to your hair by mixing equal parts of each. After a few hours, rinse it out with water. To fully remove the color, this method may require several applications.

PRO TIP: You can mix baking soda with clarifying shampoo to boost the effect of both products for better results.

You may need to be patient and allow time for the color to fade completely using these methods. Additionally, it is important to deep condition your hair after using any of these methods (except waiting 😀 ) to help nourish and repair it.

How can I make semi-permanent hair color last longer?

I wanted my semi-permanent hair color to last longer because I was happy with the shade and I wanted to enjoy it for as long as possible. I also wanted to avoid the time and expense of having to touch up my roots and refresh the color every few weeks. By taking steps to extend the longevity of the dye, such as using a color-safe shampoo and conditioner and avoiding heat styling, I managed to keep the color for a few more weeks by following these steps:

• Avoid Chlorine: Swimming pools are not your friends. The chlorine inside the pool water strips of the color of your hair. Moreover, as I mentioned in my article “How to get rid of brassiness”, it can cause a brassy tone even to permanent hair color.

• Use a leave-in conditioner: This will keep the color in your hair and prevent it from becoming damaged.

• Use a color-safe shampoo and conditioner: Using a sulfate-free shampoo and conditioner can help to preserve your hair's color.

• Avoid heat styling: Using hot tools, such as hair dryers, curling irons, and straighteners, can cause the color to fade faster.

• Touch up your roots: The dye will gradually fade from your roots as your hair grows. Every few weeks, you can touch up your roots with a semi-permanent dye to prolong the color.

• Avoid hot water: Rinsing your hair with hot water after shampooing and conditioning can strip its color.

These tips will help you maintain the vibrant color of your hair.
