The harm of hair infection

Dyeing hair is a fashionable beauty method nowadays, but if it is done improperly, it can cause great harm to the body. Investigations have found that hair dyes contain some heavy metals. These heavy metals will enter the human body through the scalp hair follicle tissue when dyeing hair, which can easily lead to the occurrence of diseases, and in more serious cases even cause poisoning, especially lead poisoning.

The harm of hair infection

1. Cause disease

The main ingredients of hair dye are paraphenylenediamine and hydrogen peroxide, which will affect hematopoietic stem cells and are recognized carcinogens. It plays a role in fixing the color after dyeing hair, but it is also a strong allergen and can cause skin allergies in people with sensitive constitutions, with contact dermatitis being the most common. Cause skin allergies

Skin allergic reaction is the most common adverse reaction to hair dyeing. Some people may not have an allergic reaction in the early stages of hair dyeing, but may have an allergic reaction after dyeing their hair several times. The longer the time, the higher the chance of allergy.

2. Poisoning

Medical experts point out that if hair dye is used for a long time, as long as 1% is absorbed into the human body through the skin, it will accumulate and cause poisoning. The chemical substances will combine with certain cells, damaging the deoxyribonucleic acid in the cell nucleus, causing cell mutations and inducing skin cancer, bladder cancer, leukemia, etc. Therefore, experts warn to be vigilant about "diseases entering the body through hair."

3. Symptoms of lead poisoning

Hair dye also contains lead acetate, which contains 5 to 10 times the amount of lead in household paints and pigments. Once lead enters the human body, it is difficult to be excreted, causing cumulative poisoning, resulting in a series of lead poisoning symptoms such as dizziness, headache, fatigue, numbness of the limbs, cramping pain in the calves, abdominal pain, etc. It also enters the liver, kidneys and brain marrow, destroying the functions of these organs. In severe cases, lead can cause loss of labor.

4. Damaged hair

The hair dyeing process will affect the moisture imbalance in the hair, leading to the denaturation and reduction of a large amount of protein, etc. This causes the hair to become brittle and the fibers to break, causing the hair to lose its natural softness, toughness and lustre.

5. Hair loss

The acute and chronic stimulation of hair dye can cause inflammatory reactions in the scalp and hair follicles, which can cause the hair follicles to atrophy over time, causing the hair to become thinner and eventually causing hair loss.
