What is monilethrix caused by?
Causes. 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.
How can you get monilethrix?
Causes. In most cases, monilethrix is inherited as an autosomal genetic trait. Genetic diseases are determined by two genes, one received from the father and one from the mother. Dominant genetic disorders occur when only a single copy of an abnormal gene is necessary for the appearance of the disease.
What is the cause of beaded hair?
Monilethrix, or beaded hair, is an inherited condition whereby strands of hair take on the appearance of beads on a necklace when viewed under a microscope1. This very distinct shape is caused by the diameter of the hair shaft changing throughout the length of the hair.
Is monilethrix curable?
No effective treatment is available. A wig can be used. Some report spontaneous improvement.
What medical condition causes brittle hair?
Brittle hair is one symptom of Cushing’s syndrome, which is a rare condition caused by too much cortisol, the body’s primary stress hormone. But, notes Mirmirani, there are many other more obvious symptoms of Cushing’s syndrome, including high blood pressure, fatigue, and back pain.
What causes weak hair spots?
Causes. Trichorrhexis nodosa can be an inherited condition. The condition may be triggered by things such as blow-drying, ironing the hair, over-brushing, perming, or excessive chemical use.
How can monilethrix be prevented?
Avoiding trauma is perhaps the most effective method of managing monilethrix. This is because from birth, the hair of individuals with monilethrix tends to have an increased susceptibility to weathering and cosmetic damage (e.g., sunlight exposure, dyeing, bleaching, perming, curling).
Why does my hair have ridges?
Weak spots form at certain points along the strand. Nearby harder segments of the cortex press into these weak areas, causing nodules or ridges to form. This creates a bumpy appearance on your hair strand. It usually results in hair that breaks easily.
What does brittle hair look like?
Brittle hair can be a combination of dry, dull, frizzy, broken, split-ended, shedding and lackluster. It’s similar to dry skin in that it has a spectrum of levels, from mildly dull to full-blown breakage. Characteristics of brittle hair are: Spongy hair – hair looks spongy and tangles when wet.
Why is my hair so dry and brittle all of a sudden?
Using a harsh shampoo. Blow-drying your hair too often. Heat damage from straighteners or a curling iron. Harsh chemicals like dyes, perms, and relaxers.

What causes monilethrix?
Some people with monilethrix do not have a mutation in one of these genes. These individuals may have a genetic change in another gene, or the cause of the condition may be unknown.
What are the physical findings associated with monilethrix?
The physical findings associated with monilethrix may result from abnormalities of the hard keratin of hair and nails. Monilethrix affects males and females in equal numbers. The exact number of people affected by this disorder is not known. Monilethrix may be apparent at birth or by the age of two years.
Can monilethrix get worse over time?
In other cases, the condition may remain the same throughout life or the symptoms may become progressively worse. The diagnosis of monilethrix may be confirmed by a thorough clinical evaluation and microscopic examination of the hair. When viewed under a microscope, the hair resembles a string of evenly-spaced beads at which the hair easily breaks.
What does monilethrix mean in medical terms?
Monilethrix is characterized by a beaded appearance of the hair due to periodic thinning of the shaft. This condition results in hair fragility and patchy dystrophic alopecia (hair loss) The term Monilethrix is derived from the Latin word monile, which means necklace, and the Greek word thrix, which means hair.
