Woolly hair

Woolly hair is a distinct type of hair that is typically characterized by its tight curls and a wool-like texture. It is most commonly found in individuals of African descent, but can also occur in other ethnic groups. Woolly hair can be either a normal variant of human hair or a sign of a genetic disorder.

Types of Woolly Hair

There are several types of woolly hair, each with its own unique characteristics and associated conditions. These include:

• Woolly Hair Nevus: This is a rare condition where a patch of hair on the scalp is replaced with woolly hair. It is usually present at birth or develops in early childhood.

• Autosomal Recessive Woolly Hair: This is a genetic condition that results in woolly hair across the entire scalp. It is caused by mutations in the Keratin genes.

• Autosomal Dominant Woolly Hair: This is a less common form of woolly hair that is inherited in an autosomal dominant manner. It is also caused by mutations in the Keratin genes.

Causes of Woolly Hair

Woolly hair is primarily caused by genetic mutations. These mutations can occur in several different genes, including the Keratin genes, which are responsible for the structure and function of the hair. Other genes that can cause woolly hair when mutated include Desmoglein and Plakophilin.

Treatment and Management

There is currently no cure for woolly hair. However, the condition can be managed with proper hair care. This includes using gentle hair products, avoiding harsh treatments, and protecting the hair from environmental damage.
