Human Hair, for the most part, contains keratin (protein). The hair on our face tends to grow faster than any other body part. Well, aren’t all these human hair facts also interesting and astonishing?
An entire industry is blooming outside based on human hair and its basics. Brands go through an extensive process of trial and error to make it to the consumer’s hair care regime. Not only that, but we also have salons all around the globe giving in extra effort to help their clients with a proper hair care regime and exclusive look all the time.
While it is not always about the adults, parents also take care of their infant’s hair in the best way possible. Then also, a crippling syndrome occurs in the young, and the cause of such an act is the human gene itself. Known as uncombable hair syndrome, where the person in concern has dry and frizzy hair which goes uncombed.
Uncombable Hair Syndrome – Details
The uncombable hair syndrome starts at the very early stages of childhood, e.i, infancy and three years. But also there are instances of the same appearing as late as 12 years. However, the good news is that the condition does wear off over time, and the children as adults have natural hair lying flat.
Uncombable Hair Look And Frequency Of Cases
The uncombable hair syndrome in black hair is uncommon, and children affected usually showcase hair that is light in color or shades of silvery/blond. Their hair gets a glittery sheen. As per the look of the same, this type of hair never grows downward; instead grows in different directions from the main scalp.
Despite the change in the appearance of the same, these hairs are not brittle or fragile. However, the growth rate is slow compared to regular hair. The exact frequency is unknown, and at least a hundred cases have been filed. Uncombable hair syndrome in adults is also normal, and the person is most likely to develop the same in later life.
Mutations in TGM3, PADI3, or TCHH genes primarily cause uncombable hair syndrome.
Generally, the proteins secreted by TGM3 and PADI3 influence the trichohyalin protein produced by the TCHH-type gene. This modified trichohyalin gets attached to other trichohyalin-based proteins and molecules known as keratin intervening filaments, creating cross-links. The links combine into a dense network structure and offer a cylindrical shape to the hair shaft.
When the PADI3, TCHH, or TGM3 gene gets mutated, it creates proteins with less or no activity. Finally, the hair shaft’s shape gets altered. Common uncombable hair shapes are heart-like, flat cross, or triangular. A single strand of hair can have all these shapes along the entire length. Because the hair has an angular shape, it will never lie flat.
As already discussed, mutations in TGM3, PADI3, and TCHH genes cause uncombable hair syndrome. This is visible in cases where the individual’s parents carry copies of the genes (mutated). The setup in which the syndrome is inherited is autosomal recessive by type. Each parent does have the gene (mutated) without the symptoms and signs of the condition.
