Hair structure hides a lot of interesting things. Discovering mysteries behind each hair is the basis for cosmetics firms to find out effective hair care product lines.
Structure of each hair is a decisive factor to health, thickness, length, the sleek, color as well as growth cycle. When knowing this factor, we can easily find out the secret to take care of your care and minimize damages to the hair.
Hair consists of 2 parts, follicle, which is also called hair roots and hair shaft.
1. Hair follicle.
It is located beneath the scalp with oval structure. The hair roots are in a gourd and be nourished by tiny blood vessels.
Our hair grows regularly because central cells of gourd are split, the new hair cells push the older one on. When moving out, it they will gradually “die” to form the hair shaft.
On the average, each person has about 100,000 hair follicles, it may fluctuate depending on the gender, race. For example, hair of female is often thicker than hair of male.
Hair follicles have two important parts, one of which is sebaceous. Its function is secreting sebaceous gland so that hair becomes soft, shiny and waterproof. The changes of sebaceous gland activity are the cause of oily hair condition or dry hair. The second part is very small muscle fibers for fixing hair on the scalp.
2. Hair shaft.
Hair shaft has no biochemical exchange, so we do not feel pain when cutting hair. Until now we thought that hair shaft is made up of 3 parts: Medulla, cortex and cuticle.
Hair structure.
Medulla
It is located in the center of the hair, containing fat particles and air. Medulla is made mainly from Keratin without shape, size and specific functions. So, if hair is too thin, hair has no medulla but it is still healthy.
Cortex
– It is the most important part of hair, accounting for 80% of hair including fibrillary bundles. It contains melanin, which decides color of hair.
– In the dyeing process, cuticle opens so that dyeing chemicals seep into the middle layer in combination with colored beads causing color drawing and oxidative status. Melanin is generated from within the follicle and distributed thanks to hair. There are two types of melanin including Eumelanin for black and dark brown hair and Phaeomelanin for ruddily. Melanocytes stop synthesis causing white hair, anxiety, insomnia or old age factors, which affect the operation of the melanocyte cells.
– The various natural hair colors that we can see are created from mixing the two above pigments in different proportions.
– Hair cortex decides shape, size, color, moisture, strength, elastic of hair. Like cuticle, hair cortex may be dry, damaged cuticles while cuticle loses ability to retain moisture.
Cuticle.
– The outermost layer of hair with no color, including 6 to 10 stacked throughout keratin layers. Weak hair with light color has fewer coats. Keratin layers are linked together by a binder called KIT. Outside the epidermis covered with a layer of mucus produced by hair follicles to waterproof and moisturize hair.
– Shine or softness of hair depends on epidermis. Chemicals, dyes, shampoos, heat from dryers, pressing machine, UV rays, fluoride in tap water, swimming pool … all can eliminate KIT, keratin layers will lose binder and it is strippable. Hair becomes threadbare, damaged, tangled…
– Hair itself is a “death” structure and it is impossible to restore if it is damaged. So using recovery products to supplement essential nutrients is essential to regain smooth for hair.
However, scientists have recently discovered a great secret in hair structure. It can create real turning point in the hair cosmetics industry.
– Dr. Vesna Stanic from Brazilian Synchrotron Light Source center with his colleagues used X-ray methods to study hair structure. And then his team discovered a new layer on the cross section of hair, between cortex and the middle layer. They discovered this layer because it had absolutely no diffraction characteristics of alpha-keratin, instead it corresponds to beta keratin. The doctor said that this new layer seems to have formed from a completely different form of protein than other parts of hair shaft. This form of protein is common in reptile scab and feathers.
– From that scientists had to change the perception of hair structure. They said that, like other animals, this type of beta-keratin has ability to increase the strength of hair.
If these findings are correct, it is possible to open up a new direction to help scientists develop cosmetic hair care product lines more effectively.
