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?

Specification of semi-permanent 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.

How did I found about this hair color

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?

Main benefits from this 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?

PERMANENT HAIR COLOR SEMI-PERMANENT HAIR COLOR
DURATION ✅ Until hair grows up ⛔️ 6 weeks (4–12 washes)
MAINTENANCE ✅ Less maintenance ⛔️ More maintenance
INGREDIENTS ⛔️ May contain some harsh ingredients ✅ Less harsh Ingredients
COMMITMENT ⛔️ More commitment ✅ Less commitment
USE ⛔️ Requires professional use ✅ You can use it at home
VERSATILITY ⛔️ You stick with the color ✅ You can experiment

 

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

How to remove semi-permanent hair dye

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.

Why and when should you choose a semi-permanent hair color?

I chose semi-permanent hair color because I wanted to experiment with a new color without committing to a permanent change. This dye is a good option for trying out new shades and styles, allowing me to change my look without the commitment of permanent dye. Additionally, it is generally less damaging to the hair than permanent dye, so I felt confident that it would be a safe and effective choice for my hair. You might choose a semi-permanent hair color for several reasons:

Why should you try semi-permanent hair dye?

  • Experiment with color: It is a good option if you want to try a new hair color without committing to a permanent change. Unlike permanent dye, it allows you to experiment with different shades and styles.

  • Cover gray hair: It can be a good option if you wish to conceal a few gray hairs. It will gradually fade as your gray hairs grow out, so you won't need to worry about root touch-ups.

  • Add depth and dimension to your hair: Enhances the depth and dimension of your natural hair color. It can be used to create highlights or lowlights or to create an ombre effect.

  • Repair damaged hair: This can be a good choice if your hair has been damaged or has been treated with harsh chemicals. In addition to adding color, it can nourish and repair your hair.

You may choose a semi-permanent hair color for a variety of reasons. Whether you want to experiment with color, cover gray hairs, add depth and dimension to your hair, or repair damaged hair, this is a good option for you.

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:

How to extend the time of semi-permanent hair dye?

  • 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.

People also ask

From my work with clients, I have noticed several questions that are asked about semi-permanent hair color.

Can semi-permanent color damage the hair?

SHORT ANSWER: 👎 LIKELY NOT

In general, semi-permanent hair color is less damaging to the hair than permanent hair color, since it does not contain ammonia or bleach. The product may, however, cause some amount of hair damage if it is not used correctly or if it is used on damaged hair. After coloring, it is important to maintain the health of your hair by using a deep conditioning treatment to help nourish and repair it. A deep conditioning treatment can help minimize the risk of damage to the hair.

Can your hair go back to normal after?

SHORT ANSWER: 👍 YES

It is possible for your hair to go back to its natural color after using semi-permanent hair color. Unlike permanent hair dyes, semi-permanent dyes do not contain ammonia or bleach, so they don't permanently change the hair's structure. 

Will the color wash out completely?

SHORT ANSWER: 👍 YES

A semi-permanent color generally fades over time, usually after four to twelve washes. However, it is unlikely that the color will completely wash out, especially if you have used a darker shade. If your hair has been dyed for a long time or if it is porous, some color pigments may remain.

Is semi-permanent hair color safe?

SHORT ANSWER: 👍 YES

In general, semi-permanent hair colors are considered safe. They do not contain ammonia or bleach, which can be harsh on the hair and scalp. Although keep in mind the package instruction and perform a patch test before using. In this way, you can ensure that you won't experience an allergic reaction. Moreover, even permanent hair color can be considered safe if you go with some of the safe hair color brands.

Can semi-permanent hair color lighten hair?

SHORT ANSWER: 👎 NO

You cannot lighten your hair with semi-permanent hair dye. The color pigments in semi-permanent hair dye are deposited on the outside of the hair shaft. In order to lighten the hair, ammonia and bleach are required. A permanent hair dye that contains bleach is the best way to lighten your hair if you want to lighten it.

Can semi-permanent hair dye cover gray hair?

SHORT ANSWER: 👍 YES

Sure, semi-permanent color can cover gray hair. In general, it is less damaging than permanent hair dye, so it is a good choice if your hair is damaged or sensitive. Keep in mind, however, that semi-permanent dyes may not cover gray hairs as effectively as permanent dyes, especially if your hair is very dark or you have a lot of gray hairs.

How long should I wait between semi-permanent hair dye applications?

SHORT ANSWER: 📅 1 WEEK

The general recommendation is to wait at least a week between semi-permanent color applications. Your hair will be able to recover from the coloring process as well as the color will take time to fully develop. To give your hair time to heal, you may want to wait even longer between applications if your hair is damaged or sensitive, or if you've recently used chemical straighteners or permanent dye.
