Reasons why eyelashes turn white

I have a neighbor who is in his sixties. His hair, beard and eyelashes are all white. He smiles all day long and looks like a fairy in a fairy tale. If your eyelashes turn white at a young age like my neighbor, it is abnormal and you may have a disease like vitiligo. Here are the causes of vitiligo.

Vitiligo is a common acquired localized or generalized skin depigmentation disease. It is caused by the disappearance of melanocyte function in the skin, but the mechanism is still unclear. It can occur in any part of the body, most commonly on the back of the fingers, wrists, forearms, face, neck, and around the genitals. It can also occur in the female vulva, mostly in young women.

The cause of this disease is still unclear. Recent studies have shown that this is related to the following factors:

1. Genetic theory

Vitiligo can occur in twins and families, indicating that heredity plays an important role in the onset of vitiligo. Studies have shown that vitiligo has incomplete penetrance and there are multiple pathogenic sites on the gene.

2. Autoimmunity theory

Vitiligo can be combined with autoimmune diseases such as thyroid disease, diabetes, chronic adrenal insufficiency, pernicious anemia, rheumatoid arthritis, malignant melanoma, etc. Specific antibodies to various organs can also be detected in the serum, such as anti-thyroid antibodies, anti-gastric parietal cell antibodies, anti-adrenal gland antibodies, anti-parathyroid antibodies, anti-smooth muscle antibodies, anti-melanocyte antibodies, etc.

3. Psychological and neurochemical theory

Mental factors are closely related to the onset of vitiligo. Most patients suffer from mental trauma, excessive tension, depression or frustration during the onset or development of skin lesions. The degeneration of nerve endings in the white spots also supports the neurochemical theory.

4. Melanocyte self-destruction theory

Vitiligo patients can produce antibodies and T lymphocytes in their bodies, indicating that the immune response may lead to the destruction of melanocytes. Toxic melanin precursors synthesized by the cells themselves and certain chemicals that cause skin depigmentation may also have a selective destructive effect on melanocytes.

5. Trace element deficiency theory

The levels of copper or ceruloplasmin in the blood and skin of vitiligo patients are reduced, resulting in reduced tyrosinase activity, thus affecting the metabolism of melanin.

The above is an introduction to the reasons why eyelashes turn white, which focuses on the causes of vitiligo. Although vitiligo is an uncommon disease, it can be encountered occasionally. Some young people also have white eyelashes, which is not very beautiful and makes them look like white-browed warriors. It is recommended to see a doctor as soon as possible. I believe that it can be cured with persistent treatment. ?
