Body hair - Wikipedia
Michael S. asks: Why does testosterone cause more body hair? Known as “ androgen receptors” (in the case of hair), they reside in an area of. Yes, Its logic is very simple that why men have more body hairs than women. The major cause of the body hairs growth with high testosterone levels is the. Linear facial hair growth and the density of facial hair were measured by a photographic method and their relationship to plasma testosterone (T) and.
It also has a big impact on skin, skin appendages, and hair in particular. Testosterone increases sebum production seborrhoea and controls hair growth as well as hair loss in certain areas of the body. Keywords Testosterone; Seborrhea; Acne; Androgenetic alopecia; Hirsutisma Impact of Testosterone on the Skin There is specific impact of steroid hormones in both sexes. Androgens stimulate sebum production. Therefore, due to higher androgen levels male seborrheic glands produce more sebum leading to fatty glow and coarser pores of the skin [ 2 ].
Consequently, acneacneiform eruptions, and blemishes are more common in seborrheic areas face, back, upper thorax, shoulders Figure 1. Comedones act as ideal breeding ground for habitual microbacteria like several cocci, propionibacterium acnes, and certain malassessia species, making them proliferate above physiological amounts.
Severe manifestations may also involve sweat glands leading to hidradenitis or cause fistulae and gum boils in axillary, inguinalor perineal locations.
Early treatment of acne lesions aims at limitation of long-term sequels. Wet shaving is an additional risk factor for male facial skin, causing dryness, irritation, redness, and exfoliationas well as cutting damage caused by the razor blade followed by bleeding and scar formation.
Decades back, male skin care consisted of washing and shaving only, since the beginning of the 21st century it has changed a lot. Today, skin care products particularly designed for male skin have revolutionized the market.
A great variety of cosmeceuticals, aligned to the individual skin type, is now used by the young generation.
Why Testosterone Affects Body Hair Growth
In general, water contact exhausts lipids from epidermal skin layers. Frequent water contact disturbing the barrier function of the skin, leads to dryness and eczema reactions. Moreover, testosterone has proven negative effect on the barrier function, making male skin particularly more sensitive than female skin [ 3 ].
Regular application of skin care products can reduce vulnerability of the skin and eczema probability by supplying the skin with lipids and moisture. On one hand, male skin regenerates more quickly than female skin due to testosterone controlled higher cellular turnover, on the other hand wound healing turns out to occur more slow than in females, due to higher testosterone levels [ 4 ].
In females hyperandrogenism causes characteristic changes of the skin and impacts on hair growth, resulting in fatty skin and hair by increased sebum production seborrheaacne, hirsutism, androgenetic alopeciaas when all together, they can be summarized under the term SAHA-syndrome and hyperpigmentation in skin folds, referred to as acanthosis nigricans. Severity may vary, but exclusion of polycystic ovary syndrome should be accomplished [ 5 ].
There is a lack of evidence-based literature on the context of testosterone and skin aging [ 6 ]. Sparse trials have shown that there is no specific difference in skin aging processes in both sexes.
Presumably, males tend to develop a larger number of seborrheic keratosis and females preferably solar lentigines [ 7 ]. UV-exposure and Fitzpatrickskin- type are predispositions for developing wrinkles and rhytides in both sexes [ 8 ]. Males may develop melanomas more easily than women [ 910 ]. Impact of Testosterone on Hair Growth Hair follicles develop during the first trimester of fetal development.
At that time the whole skin except palms and soles, lips and semimucosal areas is covered with fine lanugo hair follicles. Androgens play an important role in androgenic hair loss, even if androgen levels are within normal ranges, as androgen sensitivity of the hair follicles varies individually due to genetic determination.

It all comes down to your hormones, specifically testosterone and dihydrotestosterone or DHT. Regular testosterone is converted to the more potent androgen hormone DHT.
The amount of DHT you have in your reproductive system directly effects your beard and hair growth patterns.
There's tons of scientific research that I'm not going to cover. If you are interested in reading into the real nitty gritty information head over here. All men have this hormone to some degree as it is naturally produced. How your body reacts to the hormone also plays a role in beard and hair growth. Men with higher levels of testosterone and DHT will typically have significantly more facial hair than men with lower levels.
If your body is genetically prone to be sensitive to these hormones, you'll likely grow a beard at an earlier age than others.
Impact of Testosterone on Hair and Skin
Have you ever wondered why guys with the absolute best beards tend to be bald or balding? Having elevated levels of DHT can lead to a strong, healthy beard, but sensitivity to the hormone can actually lead to accelerated male pattern baldness. That's right, the same chemical that can benefit you hair growth and reproduction system can actually make you lose the mane up top.
The hair follicles begin to shrink with age causing your hair to thin out. It is said that high levels of DHT will expedite the process eventually leading to the closing of hair follicles and ultimately hair loss. On the other end of the spectrum, guys with lower levels of testosterone have a better chance of keeping their head hair. That being said, just because you are in your 20's and still have a patchy beard, it doesn't necessarily mean you have low hormone levels.
If your body is less sensitive to the effects of testosterone and DHT, you will see slower beard and body hair growth patterns. Hope Is Not Lost It's definitely a bit of a catch The beauty about having lower testosterone levels and less sensitivity is you can supplement and boost your hormone levels. Natural testosterone supplementation can and will increase your stamina and ability to build muscle.
However, it is not guaranteed to be converted into the androgen form DHT.
Unnatural alternatives such as anabolic steroids will cause you to grow more body and facial hair. This has been proven time and time again.
