The Function Of Testosterone In Humans
The testosterone hormone is an androgen found in men and women. In men, testosterone regulates fertility, red claret cell distribution, muscle mass, and fat distribution. Women'due south ovaries produce testosterone in small-scale amounts. It combines with estrogen (the female sexual practice hormone) to aid with the growth, repair, and maintenance of the reproductive tissues and bone mass.
Testosterone also impacts scalp hair growth in both men and women. Let'south discover out how in the following sections.
Event Of Testosterone On Pilus Growth In Men
DHT or dihydrotestosterone, produced past testosterone and the enzyme v-blastoff reductase, causes hair loss in specific areas of the scalp and controls hair growth in androgen-sensitive areas in older men (1). Androgenic sensitivity in the scalp causes the hair follicles to shrink, leading to androgenic baldness. You may notice balding on the frontal hairline, vertex, and consummate balding.
Result Of Testosterone On Hair Growth In Women
The function of androgens, especially testosterone, in female person pattern hair loss is not clear (ii). Female design pilus loss is more than likely to exist caused by androgen metabolites similar Di Hydro-epi-androsterone (DHEA) and androstenedione (i).
Androgenic alopecia in women occurs mostly in the parietal area. Some women may feel excess hair growth due to androgen production, and the condition is called hirsutism. It affects close to 5% of women (1).
It turns out that testosterone is not the existent culprit behind hair loss. Inquiry suggests that the active androgen DHT is to be blamed (iii). Androgens regulate hair growth non just on the scalp only too on the entire body.
How Testosterone And Androgens Regulate Hair Growth
The hair follicles incorporate unique genetic codes (i). These codes regulate when, on which body part the hair will grow or fall, and what triggers will cause that. These genetic codes decide which function of the body will be androgen sensitive. In other words, fifty-fifty if your androgen levels are normal, androgen sensitivity may cause hair loss.
DHT or dihydrotestosterone, an androgen and a byproduct of testosterone through the enzyme five-alpha reductase, causes hair loss (four).
A rise in androgen levels during pregnancy may also crusade telogen effluvium (excessive pilus autumn) in postpartum women. During pregnancy, there is a variation in androgen, estrogen, and prolactin levels. (5). After the delivery and when the placenta is removed, these hormone levels normalize. Such desperate changes in the hormone levels, coupled with stress (both concrete and mental), cause postpartum hair loss, which is noticed a few weeks afterwards delivery.
Hyperandrogenism in women as well impacts their pare and hair growth. Androgen imbalance, specially testosterone product, tin can cause hirsutism in women. This condition is marked past excessive hair growth in a male-like pattern.
Other than the hair growth, androgens can too affect the unabridged pilus cycle. Gyre further to understand how.
Understanding Androgens And The Human Hair Growth Cycle
The hair growth cycle has four stages:
- Anagen (growth phase)
- Catagen (regression phase)
- Telogen (resting stage)
- Neogen/Exogen (when the pilus falls out and new growth starts
Androgen levels tin can interrupt this bicycle at whatsoever fourth dimension and cause hair loss.
High Testosterone Vs. Low Testosterone
Low and high androgen levels can cause the hair follicles to stop growing new hair shafts (6). This prevents hair growth but allows old pilus to fall out, causing pattern pilus loss.
The connection betwixt testosterone levels and hair loss in men and women varies. Men incur hair loss when there is an overproduction of the DHT hormone.
Research shows that women with low or loftier androgen levels have hair growth issues. While excess androgen may cause excess pilus growth in women, a study establish that serum testosterone levels are lower in women experiencing hair thinning (7) (3).
Aberrant androgen levels may as well cause androgenic alopecia.

What To Do If You Experience Balding When Trying TRT
Hair loss is a complex process and is caused past multiple underlying factors like insulin resistance, diabetes, and obesity. These factors can increase 5-blastoff reductase in your body, triggering the conversion of testosterone into DHT. This may cause pilus loss (8).
Other than these, historic period, booze consumption, medication, and sedentary lifestyle may also lower testosterone and increase DHT. These factors may contribute to hair loss while you are undergoing TRT (viii).
This is why it is crucial to consult your doctor before starting TRT. They volition determine whether yous are fit to undergo the therapy or not. In example you have experienced hair loss during TRT, the doctor may suggest discontinuing TRT. They may also suggest a few other treatment options.
