Many women overdo it with dye and damage their hair and scalp more than they realize.
For many people, hair color is not just a fashion trend, but an integral part of personal style. But did you know that dyeing your hair not only affects the health of your scalp and facial skin, but also carries a risk of allergies?
How many times a year can you dye your hair? Which colors are potentially the most harmful? How can hair be balanced and regenerated through nutrition? And what is more harmful: dyeing your hair or perming it?
These questions are answered by Shao Shaoming, director of the Department of Dermatology, to help you better understand all the risks.
Hair coloring limited to four times a year
How often is it healthiest to dye your hair?
- It is better to dye your hair. once every three months, so maximum four times a year. Since dyes contain many chemical components, metal toxicity and absorption through the skin can cause reactions such as redness, itching and various forms of allergic contact dermatitis. Furthermore, many studies show that frequent hair dyeing can increase the risk of urinary tract cancer, so care and control of the frequency of dyeing is necessary, he explains.
Avoid contact of paint with skin.
Many girls can't give up their light shades and frequent coloring, and the more often they dye their hair, the more addicted they become to the process. Shao warns that bleaching and coloring require multiple applications of dye for the color to set well, so the lighter the shade, the more harmful it is to the hair and scalp.
He advises that before painting, always apply a protective scalp lotion, do not use products of unknown origin and be careful not to let the dye touch the skin behind the ears, on the neck or on the face, because otherwise the risk of allergies increases significantly.
Also, he remembers that the strong smell of some paints It can irritate the respiratory tract and cause allergies or asthma, so special care is required during use, reports the Telegraph.
Drink water and take vitamin C to detoxify the body
Hair coloring can affect the body to a certain extent, so it is important to take care of the body after this process. Dermatologist Dr. Qiu Qiuming emphasizes that after coloring it is important to drink enough water and to take vitamin C supplements.
Water helps speed up metabolism and eliminate paint residue from the body more quickly, while vitamin C has powerful antioxidant properties, neutralizes free radicals, and reduces the burden on the body.
He recommends including more in the daily diet. guava, tomato, kiwi, lemon or orange, to help the body cope with potential damage from hair dyes.
Avoid hair breakage and skin irritation by not coloring and perming at the same time.
It is often heard that hair coloring and perming should not be done at the same time, but for those who are short on time, this seems like the most practical solution. However, why do hairdressers and doctors advise against having these two treatments on the same day?
"Hair coloring and perming use different chemicals, and applying them at the same time is very harmful to the hair and skin. Hair becomes more prone to breakage and the scalp can become sensitive, so it's best to do these treatments separately," explains Shaoming.
Perms are even more harmful to hair than coloring.
Most people know that dye damages hair, but few realize that permanent is even more dangerousShao Shaoming explains that, regardless of whether it is a hot or cold perm, this process seriously damages the hair structure.
Whether straight hair turns curly or vice versa, the follicles must be strongly stimulated to change the shape of the hair strand, which leads to weakening and breakage. For this reason, if the goal is maintaining hair health and preventing damage, it is better to choose hair coloring rather than perming. /Telegraph/
