What color is good for hair dyeing

Hair dyes are mainly divided into plant-based hair dyes and chemical-based hair dyes. Plant-based hair dyes are mainly harmless to the body but the colors are relatively single. Chemical hair dyes are mainly serious pollutants and damage skin cells. Plant-based hair dyes are generally more common, and more and more institutions are studying plant dyeing. Chemical changes change the structure of the hair on the scalp and corrode the hair. Only plant-based hair care mainly uses physical oxidants. Don't choose a color that doesn't suit you, as this will bring many side effects.

The hair dyes of these two products have been gradually accepted by many people. Generally, they will produce many side effects. Unless there are special circumstances, try not to use hair dye. However, many women like to dye their hair. As for what color is good for hair dyeing, you still have to choose the color that suits you. Skin test: Performing skin test on the customer can predict whether the chemical components in the dye will cause allergic reaction to the customer. To conduct a skin test, first use a scarf and towel to protect the guest, mix a small amount of dye (about 2 cm) with the same amount of hydrogen peroxide, then use alcohol cotton to disinfect the inside of the guest's elbow or behind the ear, then gently pat dry, apply a drop of prepared dye to the area just disinfected, let it slowly air dry or cover it with a dressing. Pay attention to choosing the target color requested by the customer as much as possible. Finally, record the relevant information on the hair dyeing record card, such as the customer's name, address, date, products used, etc., and inform the customer not to touch the area where the dye is applied within 24 hours.

After 24 hours, if the guest feels uncomfortable or has redness, swelling, pain, itching, etc., it indicates that the guest has an allergic reaction to the product. The dye should be wiped off immediately at this time, and the product should not be used to dye the customer's hair, but pure plant-based dyes or semi-permanent dyes can be used instead. If the customer has no adverse feelings, it means the dye does not cause allergies and is safe to use. Since customers' allergic reactions to dyes are difficult to predict and the degree of reaction of the same person may vary at different times, the ideal approach is to conduct skin tests every time a customer comes for hair dyeing to ensure their safety. Don't be afraid of trouble, as this concerns the reputation of the hairdresser and the health of the customer.

The hair strand test is done before dyeing your hair to see the actual effect of the dyed hair color. The tress test is often used to test temporary, semi-permanent or permanent dyes. To conduct a hair strand test, first cut a small strand of hair from an inconspicuous part of the head and tie the ends tightly. Next, apply the prepared dye to the hair strands, follow the general hair dyeing procedure, and finally wash and record the results.

The hair strand test can clearly tell the hairstylist and the customer how the hair reacts to the dye. For example, if the porosity of damaged hair is uneven, the color of the tested hair will be uneven. At the same time, the hair strand test can help the hairstylist decide whether to continue using the same dye for dyeing the hair. We have introduced the methods of skin testing and hair bundle testing before dyeing your hair. Now let’s take a look at the porosity test and elasticity test.
