You're probably not 100% asian. Perhaps someone in your family(NOT immediate) is not asian, perhaps that gene skipped to you. It happens.
OR
hormones in foods caused a reaction.
So what's the difference between Hirustism and hypertrichosis?
Isn't there any medications to prevent or slow the growth of hair growth?
Hi,
The individual occurrence and characteristics of chest hair depend on the genetic disposition, the hormonal status and the age of the person. The genes primarily determine the amount, patterns and thickness of chest hair. Some men are very hairy, while others have no chest hair at all. Each pattern of hair growth is normal.
The density of the hair (in hair follicles per square centimeter) thickness of the hair, color of the hair, speed of hair growth, and qualities such as curliness, vary from one part of the body to another, and from one person to another. All of these features have strong genetic determinants, as demonstrated by the heritability of these qualities.
Considering an individual occurrence of chest hair as abnormal does not implicitly depend on medical indications but primarily on cultural and social attitudes. An excessive growth of terminal hair on the body of men and women is called hypertrichosis.
In most cases, the term is used to refer to an above-average amount of normal body hair that is unwanted and is an aspect of human variability.
In the vast majority of cases, hypertrichosis is a cosmetic problem. The treatments range from camouflage (e.g., bleaching with hydrogen peroxide), to temporary removal by waxing, or permanent removal by electrolysis or laser destruction of hair follicles.
