Is dyeing black hair harmful to your health?

In general, the risks of dyeing hair may include:

1. Allergy

Hair dye does contain some substances that may have an impact on health. So be sure to pay attention to any discomfort after dyeing your hair.

For example, scalp redness, itching, desquamation and other minor conditions, more serious allergic reactions such as scalp and facial edema, long blisters, etc., generally appear within a few hours to a few days after hair dyeing.

If the situation is serious or lasts for more than two days, you must go to the hospital dermatology clinic in time.

2. Hair damage

Repeated use of hair dye will make hair more and more slender and fragile, and it is more likely to be injured later.

Therefore, hair that often uses hair dyes is likely to become dull and lifeless, and even lead to pathological hair loss.

3. Heavy metal poisoning

According to Hygienic Standard for Cosmetics (2007 edition):

Hair dyes allow a certain dose of mercury, lead and arsenic.

And some poor quality hair dyes may contain more lead.

Therefore, long-term repeated hair dyeing may indeed cause chronic lead poisoning.

Common hair dyeing types can be divided into:

Permanent hair dyeing;

Semi-permanent hair dyeing;

Temporarily dye your hair.

Speaking of people's concerns about hair dyes, 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 itchy scalp after dyeing their hair.

Even temporary dyes, such as black hair dyes with gray hair, may contain PPDA or similar substances.

In addition, the so-called henna-based or other pure natural hair dyes are actually not safe. Henna hair dye, in particular, is actually banned in China and the European Union.

Therefore, no matter what type of hair dye it is, it is recommended to know the ingredients of hair dye before dyeing.
