Alopecia is called the partial or complete loss of hair from the head or even the whole body. It is also referred as baldness and it can affect both men and women. Men, especially older, are mainly affected by alopecia and they tend to experience hair loss at the temples and crown of their head. This type is also known as male-pattern baldness. There is also the female-pattern baldness that starts from the frontal and mid-scalp region. Hormones, stress but also genes can cause alopecia. There are a few genes, such as LINC01432, that are linked to alopecia. Depending on the single nucleotide polymorphisms that each of the implicated genes have, we are able to predict whether a person is going to develop alopecia or not in the future.
