Even though you blow-dry your hair thoroughly, your hair ends tend to be wavy. Many of you probably have frizzy hair and have trouble styling it every morning. In this issue, we will introduce in detail the causes of frizzy hair to those who suffer from such hair problems.
くせ毛になってしまう先天的な3大原因
Smooth, straight hair is every woman’s dream. However, hair quality varies from person to person, with some people having straight hair and others having strongly frizzy hair. So, what causes frizzy hair? This can be largely divided into congenital (inherited) and acquired causes. Let’s start with congenital causes (heredity).
- Curved hair follicles
Hair is the product of hair matrix cells in the hair root area that divide, keratinize, and are pushed out of the pore. For those with straight hair, the pore, which is the pathway of hair, is straight, but for those with frizzy hair, the hair root part is located in a more crooked area than the pore, and the pore is often crooked.
Therefore, it is believed that when the hair grows out, it becomes wavy.
- misalignment of hair protein bonds
Hair protein is composed mainly of four types of bonds: peptide bonds, cystine bonds, ionic bonds, and hydrogen bonds. In the case of kinky hair, these cystine bonds are not bonded straight, but are misaligned, which is thought to cause hair waviness. - disorganization of the cortex inside the hair
Hair consists of three layers: cuticle, cortex, and medulla. Of these, the cortex is thought to be related to frizzy hair.
The cortex is composed of the P-cortex, which contains little moisture, and the O-cortex, which contains moisture easily, and the ratio of these two proteins is said to determine hair quality. If they are uniform, the hair is straight, and if they are biased one way or the other, the hair is likely to be frizzy.
Three major acquired causes of frizzy hair
The most common cause of kinky hair is a crooked pore, but other causes of kinky hair can be acquired through lifestyle and other factors. Let’s take a closer look at acquired causes below.
- clogged scalp pores due to incorrect hair care
If you do not wash your scalp thoroughly with a daily shampoo, the pores become clogged with sebum and dirt, which deforms the hair into an oval shape and causes hair to wavy….
Continued use of shampoos with strong degreasing power, such as those containing sodium laureth sulfate, will dry out the scalp and conversely increase sebum production, making it easier for pores to become clogged.
- Hair damage
If hair damage progresses due to frequent coloring or perms, the hair’s moisture content decreases and becomes severely dry. Dry hair can also lead to frizzy hair. - unbalanced nutrition
Unbalanced nutrition due to dieting and poor circulation due to cold sores can cause blood flow to the scalp to stagnate, preventing nutrients from reaching the hair properly. This can lead to thinning of the hair and increased frizziness.
The solution to frizzy hair starts with understanding the cause of the problem.
The causes of frizzy hair vary from person to person. If you suffer from frizzy hair, first find out what causes your frizzy hair, and then figure out what to do about it!
