Hair dyeing has become a common beauty care method in modern life. Whether it is to cover gray hair or pursue fashion trends, more and more people choose to use hair dye to change their hair color.
1. Understand the basic types of hair dyesPermanent hair dye is a hair dye product that can permanently change the color of hair. It penetrates into the interior of the hair through a chemical reaction, changing the hair color and keeping it for a long time. Due to its long-lasting effect and strong coverage, permanent hair dye is often used to completely change hair color or cover gray hair.
Advantages: Long-lasting effect, usually lasting 3 to 6 months, suitable for covering gray hair.
Disadvantages: The hair dyeing process is relatively complicated, which may cause damage to the hair quality and requires regular repair.
Semi-permanent hair dye does not require hydrogen peroxide and usually does not penetrate the interior of the hair, but attaches the dye to the outer layer of the hair. The dyeing effect usually lasts for 4 to 6 weeks, and the color will gradually fade over time.
Advantages: It does not contain hydrogen peroxide, is relatively gentle, and is less harmful to hair, suitable for short-term changes in hair color.
Disadvantages: The color lasts for a short time and needs frequent coloring.
Temporary hair dye is generally in the form of spray or paste, and does not contain hydrogen peroxide and ammonia. It only leaves color on the surface of the hair and can be completely removed after shampooing. It is usually used for special occasions or people who want to change their hair color quickly.
Advantages: It is very quick and convenient, suitable for changing hairstyles or trying different hair colors temporarily.
Disadvantages: The effect lasts for a short time and needs frequent replenishment.
Plant-based hair dyes are usually plant-based, such as henna (henna powder) or other natural plant extracts. This type of hair dye is more natural than chemical hair dye and is suitable for people with sensitive skin.
Advantages: Gentle on hair and scalp, natural ingredients are good for hair health.
Disadvantages:the Dyeing effect is slow and not lasting, sometimes uneven dyeing, and hair color may be limited.
Hair dyes come in a wide variety of colors, from dark to light. When choosing, you first need to clarify your hair color goal. If you want to cover gray hair, you can choose a permanent hair dye with strong coverage; if you want a short-term change, you can consider using a semi-permanent hair dye or a temporary hair dye.
Cover gray hair: Choose a permanent hair dye, and choose the color depth according to your natural hair color and skin color.
Change hair color: If you just want to try a new hair color, you can choose a semi-permanent hair dye or a temporary hair dye, which can provide a variety of colors and will not cause long-term damage to the hair.
The health of your hair will also affect the results of your hair dyeing. For dry, brittle hair, choose a milder, semi-permanent or plant-based hair dye that does not contain ammonia or hydrogen peroxide. If your hair is in good condition and you want to keep the dyeing effect for a long time, you can choose a permanent hair dye.
Hair dyes contain a variety of chemical ingredients that may cause allergic reactions. Before use, be sure to do an allergy test. Many hair dye brands recommend doing an allergy test 48 hours before use, which involves applying a small amount of hair dye behind the ear or on the inner arm to observe whether there is redness, itching or other discomfort.
If you are concerned about chemical ingredients damaging your hair or irritating your skin, choose hair dyes that do not contain harmful chemicals. For example, choose hair dyes that are ammonia-free, hydrogen peroxide-free, or hair dyes that are made from natural plant ingredients.
Before dyeing your hair, doing a good job of preparation can ensure that the dyeing process goes more smoothly and avoids potential risks. Here are some important steps to prepare before dyeing your hair:
It is best not to wash your hair before dyeing. Because the natural oils of the scalp will be washed away by newly washed hair, and these oils can protect the scalp to a certain extent and reduce the irritation that may be caused by the dyeing process. Therefore, it is recommended to wash your hair the day before dyeing.
Hair dye may stain clothing and the surrounding environment, so you need to take protective measures when dyeing your hair. Wear old clothes or hair dyeing gowns to avoid spilling dye on your skin and clothes. At the same time, lay out dye cloths or towels to prevent hair dye from staining furniture or floors.
When dyeing your hair, you need some tools to help you operate, such as hair dye brushes, hair dye bowls, gloves, hair dye capes, etc. Make sure these tools are clean and ready to go, so you don't get lost midway.
Before using any hair dye, you should do an allergy test. Apply the dye behind your ear or on the inside of your arm, and observe for any discomfort within 48 hours, such as redness, swelling, itching, etc. If any discomfort occurs, it is recommended to stop using the dye immediately.
The operation and precautions during hair dyeing are crucial. Make sure to follow the correct steps to achieve the desired effect and ensure safety.
Different brands and types of hair dyes have different usage methods. Before using hair dye, be sure to read the product's instructions carefully and follow the steps in the instructions. In particular, the dyeing time and the mixing ratio of the dye need to be strictly followed.
During the hair dyeing process, the dye should be applied gradually from the roots of the hair, and then applied to the ends of the hair. This is because the roots of the hair usually need to be dyed a little longer, while the ends of the hair may need a shorter dyeing time because they are farther from the scalp. When applying, pay attention to even distribution to avoid uneven dyeing.
Do not leave the hair dye on your hair for longer than the recommended time. Too long contact with the hair dye may cause hair damage and may even irritate the scalp. Make sure to wash the hair dye on time for best results.
After dyeing your hair, rinse the hair dye out with warm water until the water runs clear. Afterwards, use a gentle conditioner to nourish the hair and help seal the hair scales to maintain the durability of the color and the shine of the hair.
After-dyeing care is essential to maintain hair color and hair health. Here are some effective tips for after-dyeing hair care:
Use shampoos and conditioners designed specifically for dyed hair. These products usually contain pigment-protecting ingredients that can help maintain hair color and reduce the fading of hair dye.
Dyed hair is more fragile. Excessive use of hot tools such as hair dryers, straighteners or curling irons may accelerate hair dryness and damage. It is recommended to reduce the use of hot tools or apply protective hair masks or hair oils before use.
Regularly use hair masks and deeply nourishing hair care products to help restore hair quality, keep hair shiny and healthy, and prevent dryness and breakage caused by dyeing.
