How To Avoid Dark Roots Blonde Hair?

How to avoid dark roots blonde hair and have a natural dyed hair or a colored human hair wig? Whether you wear a colored human hair wig or colored hair, you will experience a hair embarrassment period, the new roots are black, and the ends of the hair gradually fade to yellow. It's ugly, how it's formed and how to avoid it, I'll tell you today.

Ⅰ. Why do dark roots blonde hair appear?

1. In black hair, the yellow pigment is the most stable, and the blue pigment is unstable

The hair cross-section is divided into three layers, the epidermis (cuticle), the cortex, and the medulla. Pigments are concentrated in the cortex. All native black hair is the most pigmented, mainly composed of red, yellow and blue primary colors. Among them, blue accounts for the most, but the blue pigment is relatively weak. Yellow is the least, but the firmest. Red is centered.

2. The dyeing process causes the loss of blue pigment

After bleaching powder acts on the hair, the color is not added to the pigment, but the color is displayed by removing the pigment from the hair little by little. The blue pigment removes the hair from black to red (brown), and the red pigment removes the hair to yellow. What we are talking about here is bleaching, that is, fading.

As for conventional hair dye, it is not like paint attached to the surface of the hair as everyone thinks (except for some waxing products). Conventional hair dyeing is to use hydrogen peroxide to open the first epidermis layer of the hair, remove the pigment corresponding to the degree of hydrogen peroxide, and then bring the artificial pigment into the second cortex layer to combine with the natural pigment. 

So why does it fade and appears dark roots blonde hair? because the blue pigment is relatively weak. When the hair encounters alkali, the cuticles of the epidermis will open when it is heated, and the blue pigment will slowly be lost. The degree of fading depends on the hair type. Of course, the degree of fading of blackened hair is relatively slow. He added a lot of melanin that his hair didn't have.

3. The deacidification environment accelerates the loss of hair hormone and the growth of new dark hair

Most high-end hair products require deacidification, which removes (burns) the cuticles. Washing with alkaline shampoos may accelerate pigment loss. The alkaline shampoo products you usually use will keep the hair in a deacidifying environment for a long time, which will accelerate the loss of your blue pigment. At the same time, you will also grow new black hair, which will form dark roots blonde hair.

Ⅱ. How to avoid dark roots blonde hair and make it natural?

1. Use color conditioner for long-term use

There are many conditioners on the market that are tinted to keep your dyed color in and make it last longer. Of course this process is constant. The longer the maintenance work you do, the less embarrassing period of dark roots blonde hair will come. At the same time, color conditioners are usually very moisturizing to repair your damaged cuticles.

Overtone is recommended here, which does not hurt the hair. If you want more color, apply it evenly on the hair when the hair is dry, wear a shower cap and wait for 15 minutes to rinse off. If you want lighter hair color, just use the same as a normal conditioner.

2. Alkaline low silicone oil high content shampoo maintenance

As mentioned earlier, the more alkaline the environment, the faster your hair will turn yellow, and the newly grown hair will be black and in an embarrassing period of hair. Since we are dyeing our hair, or wearing human hair wigs, most of them have been deacidified. Therefore, to avoid dark roots blonde hair, first use a shampoo with relatively low alkalinity and relatively high silicone oil content, and then use it with conditioner. The cleaning frequency is ten to fifteen days.

3. Be sure not to use anti-dandruff, oil control, cooling mint and other types of shampoos, and use professional wig products

Generally, this type of shampoo will focus on silicone-free oil, and at the same time add some similar chemical ingredients to achieve the purpose of removing oil and dandruff, such as selenium dioxide. These shampoos can make your hair turn yellower and darker with prolonged washing, resulting in dark roots blonde hair. So avoid it as much as possible. At the same time, the use of professional cleaning products will be more conducive to the maintenance of hair color. Each brand has its own cleaning products (except Sanwu products). Professional cleaning products are all proportioned with the factory's deacidification solution and are related to pH.

4. Try to choose a darker hair color or a darker wig

When you choose a darker color to dye your hair, it will strengthen the proportion of blue pigment in your hair and make the lost blue pigment stronger. This is also one of the ways to reduce premature exposure to yellow pigment. When the blue pigment is replenished, it will mask the yellow pigment, allowing your hair to retain its dark color. Of course this is also time-limited. It's just that the contrast of light-colored hair can avoid the arrival of dark roots blonde hair later. After all, light-colored hair needs to be bleached and deacidified, which will accelerate the arrival of dark roots blonde hair faster.

5. Regularly go to the hair dye shop to touch up the color

This can be achieved on the basis of your time and money, and there will be professionals in the barber shop who will complement your hair color. But this needs to be done regularly, and once you stop, dark roots blonde hair will still appear.

6. Trim your hair regularly

We say that black hair will gradually grow at the roots. When we shorten our hair regularly, the proportion of black hair will be more and the proportion of yellow hair will be shorter. After a certain period of trimming, there will be no trace of yellow in your hair. Your hair will be natural black again. Dark roots blonde hair may appear on damaged hair, but not at all on new hair.
