Dye your hair to change your mood; however, the fees for hair dyeing on the market have always been high and low. In addition to the debate over whether the high fees are reasonable, damage and color loss that is not as expected are also key points that must be paid attention to before dyeing your hair.
Leaving aside the gap caused by poor communication, the problem that many people encounter is that they spend time and money on going to a hair salon to change their hair color, only to have their hair color gradually fade within a month, and the hair quality looks worse and worse.
Before you encounter problems with hair dyeing, you should first understand the situations you may face after dyeing your hair and what concepts need to be corrected. Hair dyeing is to let the pigments in the dye enter the hair cuticles of the hair to color the hair. As for problems such as fading, yellowing, and deterioration of hair quality after dyeing, the basic issue is how to maintain the hair after dyeing.
1. Can I wash my hair two days after dyeing it? YES
A Japanese study on hair dyeing found that the pigment will not last longer just by washing it every few days, but the most common thing you hear from hairstylists is “wash your hair after two days.”
This argument, it is mainly related to “stability”. Hairstylists recommend washing your hair 48 hours after dyeing. This is because when your hair is just dyed, the hair cuticles are relatively open and not completely closed. If you use the wrong shampoo at this time, it is easy to cause pigment loss. At the same time, the stability of the pigment particles in the hair is not enough, so it is recommended to wash your hair after about 48 hours to make the pigment more stable and lasting in the hair.
2. If the shampoo bubbles are colored, is it because the color fixation is not done properly? NO
Many people feel that they have problems with fading and color fading not long after dyeing their hair. They may even find that the color is washed away when they go home to wash their hair after dyeing, and they can’t help but wonder whether the “color fixation” is not done well.
It turns out that the more pigment you use, the easier it will be to wash out the color, which is normal. Usually, European and American dyes have a heavier pigment content, so the color will fade a lot after washing. As for Japanese dyes, no matter what color you choose, the feeling will be the same after washing.
This is not to say that European-style dyes are not good, but more pigments are added to achieve a brighter color. After about three or four washes, the bubbles will return to their normal color. If you are worried, you can rinse your hair with clean water several times before washing your hair until the color of the dye fades. You can put a towel on your pillow when sleeping to avoid staining your pillow if your hair is not completely dried.
3. Don’t wash your hair with hot water after dyeing it? YES
If you want your hair color to last longer, try not to wash your hair with too high a water temperature. High temperatures can easily cause pigment disintegration and over-irritate the scalp; however, cold water that is too low is not suitable as it can easily leave dirt in the hair scales and cannot be thoroughly washed away. It is recommended that warm water that does not exceed 40 degrees Celsius is best. It is almost warm to the touch and a little cooler.
4. Should I use color-protecting shampoo after dyeing my hair? YES
One of the most commonly heard sayings about after-dye care is to use a color-protecting shampoo after dyeing your hair. As for whether it is necessary? You need to understand that general shampoos are alkaline. The higher the alkalinity, the wider the hair cuticles will open and the stronger the cleaning power. At this time, the hair color will also be easily lost. As for the color-protecting shampoo, it is a little more acidic, so it is not only washed within 1 month or 3 months after dyeing but it is recommended to continue to use color-protecting shampoo as long as the hair is dyed, which can more or less protect the hair. color effect.
If you encounter some conditions on your scalp, such as a strong odor or lack of freshness, you can use it alternately. For example, use the color-protecting product one day and the deep-cleansing product one day, so that your hair color can be maintained for a longer period.
5. The lower the temperature during blowing, the better? NO
If you want your hair color to last, it is absolutely important to avoid heat damage. However, it is not recommended to blow with cold air. This will not only take a long time to dry but also fail to achieve the shaping effect. Be sure to prime your hair when it is wet. Applying hair oil, anti-heat cream, anti-heat spray, etc. can help slow down the loss of hair color and prevent heat damage.
Hot tools such as curling irons and hair straighteners can also be used, but you can choose some styles designed to reduce heat damage, and the temperature setting is below 180 degrees Celsius, which will cause less damage.
6. Do you need to take care of your hair frequently after dyeing your hair? YES
Just like taking care of your face, hair care is a concept of shrinking pores. When you wash your hair, the hair cuticles are open, and using hair care products can help tighten and repair them. In addition, many ingredients repair damaged hair cuticles and can provide nutrients that need to be supplemented after hair dyeing.
In addition, there are many hair care products on the market. In addition to color protection and brightening, you can also add pigments. For example, if you dye your hair with reddish, green, or purple colors, there are corresponding pigment conditioners. Products like this can help replenish the loss and provide nutrients, which is a very good choice.
What are the differences between color-replenishing, color-correcting, and color-protecting shampoos?
After dyeing your hair, do you have to be extra particular about choosing shampoo? This is necessary to make dyed hair color last longer and maintain healthy hair quality. In addition to using “Colour protecting” shampoo after dyeing your hair, you also often hear about “Color enhancing” shampoo, or even “Anti yellow shampoo”. Will it be subject to an IQ test? Tax?
Hair bleaching is to decompose the melanin in the hair cuticles to lighten the hair color; hair dyeing is to let the pigment in the dye enter the hair cuticles to color the hair. However, because the hair cuticles will completely open when they are exposed to water when washing your hair, resulting in rapid loss of the dye’s pigment, this is why the color will fade after washing your hair.
To extend the color-lasting time of dyed hair, it is necessary to correctly use color-replenishing, color-correcting, and color-protecting shampoos at different times. What are the differences between the functions of these three shampoos, and how to choose?
Color Replenishing Shampoo: Replenishes lost hair color
If the hair color you dye is special, it generally needs to go through the “bleaching” process, and the hair color that needs to be bleached almost all fades very quickly, so you need to use a color-replenishing shampoo to allow the user to Use the pigments in color-correcting shampoo to complement the original color.
To put it simply, it is “replenishing pigments”. During the hair-washing process, the pigments in the shampoo are used to supplement the original dyeing color. It has the highest pigment content and can be used to supplement various hair colors. It can also be mixed with colors, such as gray mixed with purple to gray purple, and can be used flexibly to replenish the lost color.
The time to use it is about 3 to 8 weeks after dyeing your hair (it depends on each person’s hair condition). It is recommended that you wait until the hair color starts to gradually lighten, then you can start using a complementary color shampoo that is similar to your hair color. Just use it 1 to 2 times a week.
Color correcting shampoo: correct yellow color after bleaching
If you bleach your hair before dyeing it, it will gradually turn yellow as the color fades. At this time, color-correcting shampoo uses the principle of complementary colors to add a small amount of blue or purple pigments to the shampoo to offset the yellowish color of the hair and turn the hair color into a more matte color to achieve the desired effect. It has a yellowing effect, so color-correcting shampoo is also called “anti-yellowing shampoo”.
However, if you start using color-correcting shampoo after you have just dyed your hair and the yellow tone in the hair color has not yet begun to appear, the blue or purple pigment may affect the originally dyed hair color, causing the hair color to blend into another color. Kind of color! Therefore, the best time to use it is to start using it after dyeing your hair and the color becomes desaturated and becomes yellowish. Use 1 to 2 times a week.
It is worth noting that whether it is a color-replenishing or color-correcting shampoo, the addition of “artificial pigments” can easily irritate the scalp, causing redness and itchiness. People with sensitive scalps may also excessively secrete oil due to pigment residues, causing scalp growth. For acne, it is recommended to use color-protecting shampoo after washing to avoid pigment residue on the scalp and help maintain scalp health.
Color-protecting shampoo: slows hair color loss
Compared with the above two methods, which are mainly designed to replenish pigments and correct color, color-protecting shampoo is more like a hair care product to “slow down” the loss of hair color. Bleached and dyed hair is damaged hair and is usually alkaline, easily accelerating color loss. Color-protecting shampoos are weakly acidic or neutral, which can balance or maintain the PH value of the hair and delay color loss.
Those who use color-replenishing and color-correcting shampoo products are recommended to wash their hair with a color-protecting shampoo after shampooing. In addition to reducing pigment residue, it can also make the hair color last longer and reduce the burden on the scalp caused by pigment residue.
