Whether you want to become beautiful and white, or simply want to cover white hair, hair dyeing has become a choice for more and more people to change their image.
However, worries about hair dyeing are also gradually increasing, such as hair dye allergy, carcinogenesis and alopecia.
Are all these rumors true?
How can one dye one’s hair to ensure beauty while not damaging one’s health?
Today we will talk about it in detail.
Hair dyeing does have unsafe factors,
Generally speaking, the risks of dyeing hair may include:
1. Allergic reaction
Hair dye does contain some substances that may have an impact on health. Therefore, after dyeing your hair, be sure to pay attention to whether you feel uncomfortable in what.
For example, lighter conditions such as scalp redness, itching and desquamation, and more serious allergic reactions such as scalp and face edema and long blisters, usually occur within hours to days after hair dyeing.
If the situation is serious or lasts for more than two days, you must go to the dermatological department of the hospital to see a doctor in time.
2. Hair damage
Repeated use of hair dye will cause hair to become more and more slender and fragile, and will be more vulnerable to injury in the later period.
Therefore, hair that often uses hair dye is likely to become dull, lifeless and even lead to pathological alopecia.
3. Heavy metal poisoning
According to < < Cosmetic Hygiene Code > > (2007 Edition): Hair dye allows a certain dose of mercury, lead and arsenic.
Moreover, some hair dyes of poor quality may have higher lead content.
Therefore, long-term repeated hair dyeing may indeed cause chronic lead poisoning.
Before dyeing your hair, you should know the hair dye first.
Common hair dyeing types can be divided into:
- Permanent dyeing of hair; Semi-permanent hair dyeing; Temporary hair dyeing.
When it comes to people’s worries about hair dye, we have to talk about one of the common allergic substances-p-phenylenediamine (PPDA).
PPDA exists in almost all permanent hair dyes, whether cheap or expensive, so many people will have allergic reactions such as scalp itching after dyeing their hair.
Even temporary dyes, such as black hair dyes for gray hair, may contain PPDA or its equivalent.
In addition, hair dyes that claim to be based on plant ingredients [henna] or other pure natural ones are not safe either.
In particular, henna hair dye is actually banned in China and the EU.
Therefore, no matter what type of hair dye, it is recommended to know the composition of hair dye before dyeing.
