Hair loss gene test
Hair loss is associated with genetic factors by the combined action of several genes, and 20-30% of patients with round hair loss have family history.
In addition, about 20% are associated with stress.
The hair loss gene test analyzes the genetic characteristics of an individual to examine SNPs associated with hair loss in chromosomes
It is a genetic analysis service that predicts the risk of hair loss diseases and enables early prevention and management of hair loss diseases.
Hair loss is a phenomenon that can happen to both men and women,
(Androgenetic Alopecia, AGA) is a genetic disorder.
Genetic hair loss should have a hair loss gene, It is possible to inherit from one parent.
The Androgen Receptor (AR) gene is present on the X chromosome.
A woman has a pair of X chromosomes (two) and hereditary chromosome has one X chromosome.
Because it can occur in one genotype, the incidence is relatively higher than women.

Factors causing hereditary hair loss
Genetic hair loss does not represent all genetic hair loss.
The expression of hereditary hair loss is expressed by a person with a long onset period,
There may be people who are slowly and sometimes not present.
There are many factors that cause genetic hair loss.
However, the factor that accelerates the progression of hair loss is environmentally polluted environment,
Environment in which more sebum can be generated
and accumulated, more active male hormone secretion, body hormone imbalance due to excessive stress, and Irregular eating habits can accelerate the onset of
hereditary hair loss.
Environmental factor
Male hormone
