How to choose the suitable hair dye?
When choosing the right hair dye, there are several key factors to consider to ensure that the hair dyeing process is both safe and satisfactory:
1.Skin sensitivity test:
Before using hair dye, it is recommended to conduct a skin sensitivity test to avoid allergic reactions. This is because some chemical ingredients in hair dye may cause allergies, especially for permanent hair dyes containing chemical ingredients such as paraphenylenediamine. If you experience scalp discomfort during use, you should stop using it immediately and consult a doctor.
2.Choose the right type of hair dye:
1.1 Oxidative hair dye:
There are many colors and stable coloring, but the chemical synthetic substances used may induce allergies, and may also damage the hair keratin structure, causing protein loss and decreased crystallinity. Suitable for people who like bright colors and want their hair color to last for a long time2.
1.2Plant-based hair dye:
It has less irritation to the head skin and less damage to the hair quality. But it has poor stability, a single color spectrum, dark colors, and takes too long to dye. Suitable for people who are not demanding on color, like dark tones or are prone to allergies2.
3.Consider ease of use and color diversity:
If you want the hair dyeing process to be simple and quick, you can choose a hair dye that is easy to operate and has a variety of colors. Some brands offer a variety of color options to meet different needs and preferences3.
4.Brand selection:
Choosing a hair dye from a well-known brand will ensure better quality and safety. Well-known brands usually have more user reviews and feedback, making consumers feel more assured3.
Pay attention to preparation before dyeing: It is not recommended to wash your hair before dyeing, because the oil secreted by the scalp can protect the scalp from damage by hair dye and make the hair color fuller. In addition, do not perm and dye your hair at the same time to avoid excessive damage to the hair quality4.
5.Consider the shelf life of the hair dye:
The shelf life of hair dye cream can generally reach three years, but it should be sealed after opening to avoid direct sunlight1.
In summary, choosing the right hair dye requires comprehensive consideration of personal needs, skin sensitivity, chemical composition of the hair dye, brand reputation, and ease of use. Ensure that the desired hair color effect is achieved safely and satisfactorily during the hair dyeing process
