What Are The Precautions Before And After Dyeing Your Hair?

Avoid exaggerated color changes

For women, changing hair color can change your mood. It's just best not to choose a color that is too different from the original hair color, such as dyeing dark brown hair into blonde, or blonde into black. Too much color difference will make dyeing difficult. The hairstylist may use bleach or let the hair dye stay on the hair for a long time. These products containing chemical reagents may burn the scalp and may also cause severe allergic reactions. Therefore, skin experts recommend that it is best to choose three colors close to your natural hair color for dyeing.

Do an allergy test before dyeing your hair
Before using hair dye, you must do a skin allergy test. Otherwise, a large area of ​​scalp allergy will have serious consequences. But those hairstylists only dye and don't do allergy tests. Then you have to ask the hairstylist for some hair dye and do it yourself. In fact, it's very simple. Take a small amount of hair dye and apply it on your elbows or behind your ears. Observe the applied area after two days. If a rash appears, it means you are allergic to it and you must not dye it. In addition, remember not to mix different types of hair dyes. Otherwise, the chance of allergies will increase.

Be careful with all-natural plant hair dyes
Everyone thinks that chemically synthesized hair dyes are very harmful, so all-natural plant hair dyes are very popular and much more expensive. But this does not mean that we can use them with confidence. These all-natural plant hair dyes still contain strong oxidizing agents such as hydrogen peroxide, which is used to bleach hair color (especially when dyeing dark hair to light color). When hydrogen peroxide is used excessively, it will seriously damage the hair quality, so all-natural hair dyes cannot be used as much as you want. Moreover, these all-natural plant hair dyes can only cover the outermost hair scales of the hair, which does less damage to the hair, but it is more difficult to maintain the color for a long time.
