What is protein correction?

When hearing the term "protein correction", most people may think of "care", imagining it as a way to maintain hair. In fact, protein correction cannot correct anything, but is a kind of "styling". The same principle applies to the well-known straight hair and ionic perm.

The most common straight hair method uses the principle of high-temperature shaping . Through the high-temperature flat iron, the protein in the hair is turned into a disordered liquid. The hair is then straightened and cooled by the flat iron to change the arrangement and distance of disulfide bonds in the hair shaft to obtain smooth hair.

The "Tears of the Times" ion perm is shaped by applying a softener (reducing agent). It first uses a potion to open the disulfide bonds to soften the hair and lose its elasticity, and then uses a high-temperature flat iron to straighten the hair for shaping.

The principle of protein correction is similar to theirs, which is to open the hair scales and re-arrange the disulfide bonds by heating the hair . But the difference is that protein correction will apply a potion containing protein, which will deliver nutrients to the hair while styling.

The main component of the protein potion is glyoxylcarboxycysteine, which constitutes protein . It can weaken the hydrogen bonds and salt bonds in the hair and turn them into cysteine ​​bonds. Under the high temperature used in styling, it can straighten the structure of cysteine ​​and keep keratin in the hair.

I'm sure everyone has realized that "protein correction" is a hairdressing gimmick and does not have any academic professionalism. Other treatments with very similar principles include "Brazilian (BC) hair treatment", "protein polishing" and "protein implantation". They can make the hair appear to have a waterfall-like effect, mainly because one of the steps is to straighten the hair.

“Protein correction” contains formaldehyde, will it cause cancer?

When protein correction became increasingly popular in the hairdressing market, many customers began to have concerns about it.

As we all know, even ordinary perming, dyeing and straightening products contain many chemicals, some of which have negative effects on the skin, cardiovascular system and even the entire human body, such as industrial chemical bisphenol A, which is embryotoxic; parabens, which can cause dermatitis and urticaria, etc. Therefore, protein correction products on the market are not completely risk-free.

The keratin in the protein correction cream used for protein correction is mostly extracted from wool and may contain formaldehyde or formaldehyde derivatives . During the heating step, it may also emit a continuous pungent odor, which is harmful to your health.

According to the requirements of my country's Product Quality Law, products that actively add formaldehyde should be marked on the product. Although some potions do not have formaldehyde marked on the product, some institutions have conducted formaldehyde tests on hair samples that have undergone protein correction and found high formaldehyde levels.

For well-known brands of hair lotions, the formaldehyde content is relatively controlled at a low level. However, the production quality and cost of hair lotions in the market vary greatly. For some overly cheap lotions, the formaldehyde content in them is immeasurable.

If you encounter products with unguaranteed quality, they may contain excessive amounts of heavy metals such as lead and mercury, which may cause skin allergies and damage to the hair follicles.

How to take care of your hair correctly?

In fact, to improve the quality of your hair, you don't need these fancy hair care tips. Daily washing and care are the top priority . In addition to going to the hair salon for various projects, there are many ways to care for your hair in daily life.

When washing your hair daily, you should pay attention to details. Comb your hair before washing to remove some dandruff through electrostatic adsorption. After turning on the hot water to wet your hair, you don’t need to apply shampoo immediately. It is best to wash it with warm water for a while to absorb the dirt. A major way to protect hair follicles and hygiene is to try not to scratch your hair with your nails when washing. For hair care , it is best to apply conditioner to the ends of your hair. Use it two to three times a week. Finally, you also need to wash the conditioner to avoid clogging the hair follicles.
