How to dye your hair without damaging it?

Frequent hair dyeing can cause great harm to the hair and scalp, and some chemical substances in hair dyes can also affect health. Therefore, hair dyeing should pay attention to certain methods and techniques. Frequent hair dyeing is not recommended, and do not choose some inferior hair dyes casually.

1. Choice of hair dye

The products of large and medium-sized enterprises with a high market share and large scale are of better quality and the product quality is guaranteed. Don't use some hair dyes casually, as the chemical content in their ingredients may not be up to standard. After use, it is easy to cause dry hair, split ends, and even allergies and itchy scalp... It is recommended to use light-colored hair dye or hair dye that fades faster to reduce harm to the human body. Choose brands like L'Oreal, Schwarzkopf, Wella, and Bigen. The domestic brand Wen Ya is also good.

2. Don’t wash your hair the day before dyeing (this item depends on your own situation)

Many hair salons and saloons use oxidative hair dyes mixed with hydrogen peroxide. Before dyeing the hair, the hairstylist will perform scalp care and isolation to prevent the hair dye from penetrating into the scalp hair follicles. Therefore, do not wash your hair the day before dyeing it. The natural oils in the hair and scalp can protect the scalp from itching and sensitive reactions caused by hair dye. However, people who use styling products every day need to wash their hair the day before dyeing their hair. When cleaning, do not rub your hair hard or scratch your scalp with your fingers, otherwise all the natural oils will be cleaned out.

3. The minimum interval between dyeing and perming must be one week

It is absolutely impossible to complete hair dyeing and perming at the same time in a salon. First of all, the solutions used for dyeing and perming are different. If you dye and perm the hair at the same time, the newly dyed hair may lose color during the perming process; or the newly permed curly hair may lose its curl due to dyeing. Therefore, professional hairstylists usually recommend that customers perm their hair first and then dye it a week later, so that both styles can be maintained smoothly and the damage to the hair quality caused by perm or dyeing can be minimized.

4. Do a skin test before dyeing your hair

Before dyeing your hair, you should apply an appropriate amount of prepared hair dye behind your ears or wrists for 2-4 days. You can dye your hair only if there is no allergic reaction. This is because everyone's skin sensitivity is different, so you have to try it yourself before dyeing your hair.

5. Dyeing and care in one

The biggest concern of most people when dyeing their hair is the damage that the dye will cause to the hair. During the hair dyeing process, a large amount of alkaline substances enter the hair, destroying the original protein and amino acid. The dyed hair will become dry, lose luster and elasticity, so damage to the hair is inevitable. Now try to use hair dye with low alkaline content. When dyeing hair, some hair care ingredients are usually added. This is the currently popular hair care dyeing - hair care and hair dyeing are done at the same time.
