Genetic mutations determine curling or straightening

Scientists at the Queensland Institute of Medical Research (Australia) have recently discovered that human hair is curled or straightened, determined by the trichohyalin gene, or "curly hair" gene.

Nick Martin, in charge of the study, said: 'More than 20 years ago, this gene has been proven to be related to hair growth, they exist around the roots'.

It is the mutation of this gene that determines the curling or straightening of the hair. Genetic mutations may have led to a certain type of amino acid exchange, which in turn affects the curling degree of the hair.

The results of this study not only help police sketch crime portraits and investigate evidence, but also help scientists research the creation of a genomic drug that makes hair straight or curved without having to come. hair salon.
