One-time perm tutorial

Nowadays, people are very fashionable and often do one-time perm. Although one-time perm is a very simple method and can be done by yourself at home, the process is relatively complicated and it cannot last for a long time after completion. At the same time, repeated perming will cause great damage to the hair follicles of the skin and the hair quality, so everyone should understand the harmfulness of perming.

First of all, the hair is the most damaged by frequent hair dyeing and perming. Liao Liehui, chief physician of the dermatology department of Guangdong Provincial Hospital of Traditional Chinese Medicine, said in an interview with Family Doctor Online that a large amount of chemical substances are used in the hair dyeing process, among which a large amount of alkaline substances will enter the hair. Frequent hair dyeing will destroy the original amino acids or proteins in the hair, which can easily make the hair become dry, lose elasticity and luster, etc.

These chemical ingredients will damage the hair, scalp and hair follicles, thereby reducing the oil secretion of the hair. Some of the black and moisturized hair will turn yellow and brittle, lose its luster, and fall off easily, eventually leading to hair loss problems.

In addition, the paraphenylenediamine in hair dye can also cause allergies. Therefore, people with sensitive scalp or local inflammation who dye their hair frequently can easily suffer from allergic reactions such as yellowing, hardening, and pus discharge of the scalp.

1. It is best not to dye or perm your hair by yourself. You should go to a regular hair salon and use regular and safe hair dyes purchased through regular channels.

2. To maintain hair quality, it is best to wait 5 to 6 months between two perming sessions, that is, it is best not to dye or perm your hair more than twice a year.

3. It is best not to dye your hair and perm it at the same time. Do not use too many types of hair dyes at the same time when dyeing your hair, as chemical reactions may occur between the hair dyes.

4. Before dyeing your hair, make sure your scalp is not damaged, because some ingredients in hair dye and perm agents can seep into the wound and cause harm to the body. At the same time, it is best not to scratch your head hard.

5. It is best to do skin tests, hair strand tests, air permeability tests and elasticity tests before dyeing your hair.

6. It is not recommended for patients with blood diseases, asthma, urticaria, allergic diseases, people who are taking antibiotics, children, and pregnant or lactating women to dye their hair.
