What is the cause of Monilethrix?
Monilethrix is caused by mutations in one of several genes.
Mutations in the KRT81 gene, the KRT83 gene, the KRT86 gene, or the DSG4 gene account for most cases of monilethrix.
These genes provide instructions for making proteins that give structure and strength to strands of hair..
Which race has wooly hair?
Likewise, the “woolly” version is nearly exclusive to Africans. Its high prevalence could be explained by the fact that most Africans are carrying two copies of the dominant gene. This would assure that the coarse hair texture is maintained in the population.
Which race has the most hair on their head?
Caucasian hair can come in a variety of textures, including straight, curly and wavy. The thickness of the strands is also variable, as is the amount of hair on the head. Caucasians commonly have the highest hair density, with about 200 hairs per square centimeter. This can create the illusion of having thicker hair.
What is African hair called?
Afro-textured hair, or kinky hair is the natural hair texture of certain populations in Africa and the African diaspora. Despite its name, this hair texture is also found in some parts of Oceania and Southeast Asia. Each strand of this hair type grows in a tiny, angle-like helix shape.
What does woolly hair look like?
Woolly hair is a congenital structural anomaly of scalp hair occurring in Caucasians. It is either sporadic or genetic. Woolly hair is extremely curly, the average diameter of the curls goes up to approximately 0.5 cm.
What causes Uncombable hair syndrome?
Uncombable hair syndrome is caused by mutations in the PADI3, TGM3, or TCHH gene. These genes provide instructions for making proteins that help give structure to the hair strand (shaft). The proteins produced from the PADI3 and TGM3 genes modify the protein produced from the TCHH gene, known as trichohyalin.
What is Hypotrichosis?
Listen to pronunciation. (HY-poh-trih-KOH-sis) A rare condition in which there is little or no hair growth on the head, including the brows above the eyes and the edge of the eyelids, or other areas of the body where hair normally grows.
Why do Africans have yellow eyes?
Sickle cell diseases are especially common in people of African or Caribbean ancestry. They cause your body to make red blood cells that are sticky and curved and back up in your liver, and they die faster than your liver can filter them out. Bilirubin from these cells builds up in your body, causing jaundice.

What is the Waardenburg syndrome?
Waardenburg syndrome is a group of genetic conditions that can cause hearing loss and changes in coloring (pigmentation) of the hair, skin, and eyes.
What is a werewolf syndrome?
Hypertrichosis, also known as werewolf syndrome, is a condition characterized by excessive hair growth anywhere on a person’s body. It can affect both women and men, but it’s extremely rare. The abnormal hair growth may cover the face and body or occur in small patches.
