Why are your hair extensions always frizzy

Why are your hair extensions always frizzy?

The cuticle structure on the surface of the hair, the main component of which is keratin. Keratin is composed of amino acids, and the most abundant amino acid is cystine, which contains disulfide bonds as well as hydrogen bonds and salt bonds in hair proteins, which form the toughness and strength of keratin. However, these bonds are not very strong, and hydrogen bonds can be easily opened in the presence of water, especially in alkaline environments (high pH).

For example, if you wake up in the morning with messy hair, but if you comb your hair with a little water, it will press down the curled hair. This is because water breaks the hydrogen bonds of the hair, causing the curly hair to lose its elasticity. When the hair is wet, there are fewer hydrogen bonds in the hair keratin; And after the hair is dry, the hydrogen bonds in the hair keratin are rearranged and fixed. Similarly, the principle of straightening and scalding is similar, except that the disulfide bond is also opened. The perm process is actually the destruction and reconstruction of the disulfide bonds. Due to the nature of the surface structure of the hair, as well as the nature of keratin, if the cuticle on the surface of the hair is broken, the hair will be frizzy or static electricity, dry hair will feel like straw or rough to the touch, dull, dull hair, etc. Studies have shown that the material basis of hair damage is the breakage of cystine on the surface of the hair. The most significant hair damage is the loss of hair keratin. Types of hair damage: daily damage (excessive or improper combing), damage caused by sunlight (in fact, hair should also be protected from the sun), damage caused by heat treatment (using a hair dryer to blow hair), hair damage caused by perming and straightening, hair damage caused by hair coloring. 

Under the electron microscope, the cuticle of a damaged hair is dry and turned up, resulting in a greater coefficient of friction and more difficult to comb, and for all kinds of hair damage, hair care products are produced: conditioner, hair mask, pomade, etc. The basic care of these hair care products is to absorb the hair care ingredients on the surface of the hair, lubricate the hair layer, reduce friction, and reduce the risk of damage caused by the hair combing process.
