The regulation of human hair growth is one of the most mysterious of biologic events. Genetic factors are responsible for the density, length, color and texture of hair. Heredity disorders can affect either hair alone, hair and other ectodermal structures, or can be pansystemic.
Is hair growth determined by genetics?
Genetics plays a huge factor in determining how your hair will grow , how long, the thickness and color.

Your genes affect how sensitive your scalp is to a hormone called dihydrotestosterone (DHT), which shortens the growth phase of your hair. Your hair follicles also become smaller in response to DHT and you subsequently produce fewer and finer hairs.
Is Good hair genetic?
Genetic factors appear to play a major role in determining hair texture—straight, wavy, or curly—and the thickness of individual strands of hair. Studies suggest that different genes influence hair texture and thickness in people of different ethnic backgrounds.
Does hair come from Mom or Dad?
In other words, if your dad has a full head of hair but your mom’s brother is a 5 on the Norwood Scale at age 35, chances are you will follow your uncle’s journey through MPB.

Is brown hair dominant or recessive?
It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up. You can think of recessive alleles as t-shirts, and dominant ones as jackets.
Which parent does the hair gene come from?
And it is true: the hereditary factor is more dominant on the mother’s side. If your dad has a full head of hair but your mom’s brother is a 5 on the Norwood Scale at age 35, chances are you will follow your uncle’s journey through MPB. However, the gene for MPB is actually passed down from both sides of the family.

Why do Asians have straight hair?
Most people of East Asian descent have thick, straight hair. This corresponds with a SNP (rs3827760) in the EDAR gene which is involved in hair follicle development. The ancestral allele of this SNP is the A-allele. The G-allele is the newly derived allele that leads to the thick, straight hair.
