Exact time frame: 4-6 weeks

Permanent hair color, in theory, alters the original hair color to a new hue while also changing the hair structure.

It is mostly used to modify the tone of your hair and lighten or darken the color of your hair.

For those getting older and their hair becomes gray, permanent hair color can hide that gray hair and permanently alter it to another hair color of interest.

The permanent color completely covers the hair. This procedure occurs when permanent hair color is blended with a developer-activator before being applied to someone’s hair.

Also, if there are any leftover mixed items, they may be preserved for later use.

What exactly is permanent hair dye?

Permanent hair color (as the name implies) is intended to last longer than temporary and semi-permanent hair dyes, although it does not last forever.

Unlike semi-permanent hair dye, intended to last only a few shampoos, permanent hair dye penetrates the hair strands more deeply, locking in the color for a longer period.

Permanent hair color should ideally remain as brilliant as the day you dyed it, at least until the roots develop. That would imply a good 6-8 weeks between touch-ups on most heads of hair.

How Do Permanent Dyeing Processes Work?

Permanent dyes, unlike conventional dyes, do not just cover your hair like paint; rather, permanent dye permeates into the hair, allowing the dye to change the color of the hair shaft from the inside out. The permanent dye does this by activating the hair cuticle and allowing the dye’s pigments to enter the hair.

Permanent dyes are ideal for grey hair since they change/add color to the hair rather than simply covering it from the outside. Permanent colors stay longer, are less prone to flaking, and seem more natural since the color originates from within the hair.

Is it possible for permanent hair coloring to fade?

Color fading can occur after a few weeks of using a permanent dye. But why is this happening? Hair dyes are often water-soluble. When you wash your hair, the dye molecules disintegrate, and your new color is washed away. Red hair color generally dissolves the most easily in water.

As a result, this hue tends to fade the fastest. This isn’t to say that you can’t have a brilliant, long-lasting color with permanent hair dye; you have to know how to care for it and what dye to use.

How Long Does Permanent Hair Color Last?

Permanent hair color can last up to 4-6 weeks before the hair returns to its natural color.

After this time, the color will fade to its natural hue. The following methods can help your permanent hair color endure for a long time.

Keep your permanent colored hair away from the sun.

If you expose your colored hair to too much sunshine, the dye will begin to fade. This is because sunlight is the enemy of colored hair, as it will peel away the permanent hair color.

Thus, if one avoids direct sunshine, the colored hair will remain long, or one must wear caps or use UV-protected hair treatments.

Hair washes should be used sparingly.

Using shampoos regularly to wash colored hair will cause the color to fade.

Colored hair may be washed using specific shampoos designed for colored hair. As a result, using fewer washes or special shampoos designed for colored hair will help the color remain longer.

Keeping color-treated hair hydrated

Finally, after washing, the colored hair should be hydrated by conditioning it. This is due to the use of peroxide or ammonia in permanent hair color, which dries out the hair follicles and hence reduces its lifetime.

Why does color-treated hair last so long?

To begin, nourishing the colored hair will extend the life of the permanent hair. This is accomplished by applying a hair conditioner to the hair after it has been rinsed.

The moisturizer will keep your colored hair from becoming dry and drab. This is due to ammonia or peroxide in permanent hair color, which dries hair follicles. As a result, using a moisturizer will help a permanent hair color remain longer.

Another approach to extending the life of permanent hair color is to use as little shampoo as possible.

When permanent colored hair is cleaned often with hair shampoo, the colored hair becomes dull.

Washing colored hair with shampoo gradually removes the permanent hair color, decreasing the life of the colored hair. As a result, limiting your usage of hair wash will help your permanent hair remain longer.

Finally, exposing hair that has permanent hair color to sunlight will cause it to become dull, resulting in the color lasting only a short time. Wearing caps or using UV-protective hair products can help to avoid this. As a result of these precautions, the permanent hair color will remain longer.

How Do I Keep My Hair Colored Using Permanent Hair Dye?

Commitment, as with everything else, is essential for preserving the desired hair color. But be careful: dyeing your hair is a chemical procedure that, if not done correctly, may cause significant harm to your hair. In addition to the application, upkeep entails managing the type of shampoo you use on your hair.

When washing your colored hair, most stylists will advise you to use a non-detergent shampoo because fewer chemicals are working on the hair, lowering the danger of your fake pigments washing away.

It’s also advisable to avoid direct sunlight as much as possible since it accelerates the oxidation of the ammonia in the dye, which accelerates the breakdown of the colors.

It’s also a good idea to limit the amount of heat you apply to your hair, which includes curling irons and hair dryers. Excessive heat destroys the cuticles of your hair, causing the pigment in your permanent hair color to dry out and renege, giving your hair a mottled appearance.

Removing your permanent hair dye is recommended once you detect your roots are coming out. But it won’t harm to go before you notice some of your natural hair poking through; if your hair isn’t the color or tone you desire, arrange a retouch as soon as possible.

Permanent Hair Dye: How to Use It

Now that you’ve decided on a color and a dye, here are some suggestions for using permanent hair dye at home.

1: Keep Your Skin Protected

You may want to color your hair, but we’re guessing you don’t want to dye your skin (or clothing). Apply a thick coating of petroleum jelly to any regions that may come into touch with your hair or the dye to avoid coloring your forehead, cheeks, and neck.

This will be a protective barrier that may be readily removed once you’ve finished dyeing your strands. Also, dress in clothes that you don’t mind getting dirty.

2: Divide your hair into sections.

After that, segment your mane. Divide your hair into smaller, easier-to-manage parts. The thickness of your hair will determine the number of portions you use. Begin with only one section of hair hanging loose, and secure the rest of your hair out of the way using a claw clip.

3: Combine Your Colors

To mix your hair color, follow the directions supplied with your permanent hair color kit. Wearing rubber gloves to protect your hands is also a good idea at this time.

4: Use Your Hair Dye

You should apply your hair color to dry hair. Working in sections, apply the color as directed. Check that your hair is soaked and that no patches are missing.

5: Rinse and wait

Wait the specified time for your hair color to develop once your strands are thoroughly covered (set a timer, so you don’t have to guess). When the timer goes off, rinse your hair well until the water runs clean.

You don’t need to wash your hair with shampoo unless the hair dye you’re using directs you to do so—most will advise you to wait. You should, however, follow with a conditioner, which is commonly included with at-home color kits.
