Genetic hair loss is hair loss due to the genetic make-up of people. Everyone has genes within their body, inherited from the X and Y chromosomes of both parents. Studies have indicated that inheritance of hair loss only know risk gene for androgen receptor lies on the X chromosome, thus inherited from the mother’s genes.
Hair loss can be categorized into 2 kinds – Male hair loss and Female hair loss. For male genetic hair loss, research in 2007 has indicated that there is another gene on the X chromosome that lies close to the androgen receptor gene is important in male genetic hair loss. Region Xq11-q12 on X chromosome is noted to be strongly associated with male genetic hair loss. Gene EDA2R is noted to be the gene most associated with male genetic hair loss, and gene P2RY5 is linked to the hair structure. Of course, there are certain variants of genes that could have different results, for example baldness at birth or in other examples cotton hair. The X-linked androgen receptor is the most important gene, with a gene on chromosome 20/23 being the 2nd most important determinant gene.
