Why Do Some People Have No Hair on Legs and Arms? Genetics vs. Other Factors

[Jekertee]

Except the genetic factors, why do some people not have a single hair on legs or arms while some are full all over the body ? I rarely see North American men without facial hair.

On the ads I have read, there are even cream or medicine that helps hair growing. that's really funny. Is it good for the health ?

Other than genetic factors, there's shaving, depilatories (chemicals that make the hairs fall out), electrolysis (a small electric "shock" is given to the root to kill the hair cell), laser treatments (performed in a doctor's office), waxing and plucking (both are means of ripping the hairs out...OUCH!) And, of course chemotherapy can lead to hair falling out as well.

There are a few reasons why some people may not have hair on their legs and arms, other than genetics. One factor could be hormonal imbalances, which can affect hair growth and distribution on the body. Additionally, certain medical conditions such as alopecia or autoimmune disorders can also cause hair loss on the body. Some people may also choose to remove hair through methods such as shaving or waxing, leading to a lack of hair in those areas.

As for the prevalence of facial hair in North American men, this could be due to cultural norms and societal expectations. In many Western societies, having facial hair is often seen as a sign of masculinity, and therefore, many men may choose to grow and maintain it. However, this is not the case in all cultures, and there are many men around the world who do not have facial hair.

Regarding the creams and medicines advertised to promote hair growth, it is important to consult with a doctor before using them. While they may be effective for some individuals, they may also have potential side effects or interactions with other medications. Ultimately, the decision to use these products should be made after careful consideration and consultation with a healthcare professional.
