How long will permanent hair dye last?

When it comes to covering grays, permanent hair color is the best option. Since temporary, semi-permanent, and semi-permanent hair dye washes out after a period of time, the permanent hair dye has to grow out and is the longest lasting option.

What is permanent hair dye?

The permanent hair dye or oxidation relies on an oxidizer such as hydrogen peroxide and ammonia which are combined with a coloring formula before application on hair. Although, permanent hair dye has an advantage over other forms of dye since it doesn’t have to be reapplied as often – the chemicals used in the dye can be more damaging to hair when compared to other colorants. The application time for permanent hair dye is also longer since the colorant has to be left on hair for an extended time than other dyes.

How long will the permanent hair color last?

The permanent hair color doesn’t wash out but rather grows out revealing the roots. It is usually after four to six weeks when you can go and get your roots done again. The permanent hair color also starts to fade after some time (usually 28 washes) and sometimes change shades.

To get rid of permanent hair color, you can either wait for it to grow out or color over it.

Prep you hair before getting them colored:

We have all heard of things we should do after we get our hair colored, but no one puts much thought on what we should do before getting them colored for the best results. Since the dye process involves usage of chemicals and eventually dry out the hair – it is recommended to use a mask or a deep-conditioning treatment at least a week before you plan to dye your hair. This will make your hair strong and ready to receive the coloring. The healthier your hair is, the happier you will be with the color and how long it lasts.

Tips to avoid color fading.

Caring for your hair can get permanent hair dye to last for a longer period. Here are some tips on how to avoid hair color fading and get the most out of your hair color:

Keep shampooing to a minimal.

The longer you wait before shampooing the first time you color your hair, the better chance your new color will have to settle in. every time you wash your hair, the color molecules from the hair dye escape giving a boost to the fading process. Most beauty and hair expert recommend washing your hair at the most every other day to protect the coloring.

Avoid sun exposure

The sun is considered to be an enemy of color-treated hair and will eventually strip the color from your hair making them look dull. UV protection sprays for hair and caps should be utilized if you are expected to stay out in the sun for a long time to prevent hair fading.

Stay out of swimming pools

The chemicals in the pool such as chlorine can harmfully affect your hair. If you do have to go in for a quick swim, try wearing a swimming cap as it protects your hair from the chlorine-contaminated water and the harsh sunlight of beaches.

Protect your hair from heat

Blow dryers, straightening irons, curling irons, rollers – we all use them to an extensive amount. The heat from the different styling tools can dry out your hair making them look flat and limp. But since most of us can’t live without these hot tools – it is advisable to use a protective spray prior to using them. They not only shield the hair from heat, they add a nice shine to the hair as well.

Use a color-protecting shampoo

All shampoos are not made equal. There are many different varieties of shampoo which are suitable for the various hair types. Color-treated hair should always be washed with a color-protecting shampoo which is gentle and protects the hair color from fading. Sulfate-free shampoos, as well as those that include natural oils such as vitamin E and sunflower oil, will help the longevity of your colored hair.

Use a color-protecting conditioner

A color-protecting conditioner should be used every time you shampoo your hair to keep your hair hydrated. Look for conditioners that are enriched with vitamin E and sunflower oil that help fight the environmental damages to your hair.

Keep your hair moisturized

Since the permanent hair dye contains ammonia and hydrogen peroxide, they have a tendency to dry out the hair follicles making the hair look dull and lifeless after some time. By keeping your hair healthy and keeping them moisturized – you too can achieve beautiful hair and long lasting color.
Apart from using shampoos and conditioners that are designed specifically for colored hair, hot oil treatments and hair masks are also a good option to protect the colorant of hair. Both the treatments can be done once a week to keep hair moisturized and shiny.

The permanent hair dye is a long-lasting solution for those looking to cover up the grays and going for a dramatic change in their hair color. Although, it doesn’t wash out, you still have to take care of your hair by following the above tips to keep the hair color from fading.
