Sexual dysfunction should also be discussed with a doctor if symptoms develop. Evidence notes that when a person quits smoking, it is possible to undo some of the damage caused by the harmful effects of smoking. For example, within a couple of weeks to a few months, a person’s circulation may improve. Nicotine is a highly addictive substance present in all tobacco products and some e-cigarette liquids.

In addition to DHT, evidence also highlights the role of genetics in hair loss. Pattern hair loss may be hereditary for both male and female pattern hair loss. Finasteride is a medication commonly used to treat hair loss in men.

Diseases and conditions that affect testosterone
The authors of a 2021 study noted that males with high levels of dihydrotestosterone (DHT) — a substance that works with testosterone — may have a higher chance of acne and hair loss. However, they did not link this effect directly to high testosterone levels. During male fetal development, DHT plays a vital role in the development of male external genitalia.
Everything You Need to Know About Male Pattern Baldness
Patches can be applied to the thigh or torso nightly, whereas pellets must be surgically implanted under the skin every 3-6 months. No matter how it is administered, testosterone replacement therapy can benefit patients with low testosterone levels and will not directly cause hair loss or male pattern baldness. Treating hair loss caused by excessive testosterone levels often involves a multidimensional approach.
In particular, DHT plays an important role in the development of male external genitalia. It works in combination with testosterone to increase the size of the male external genitalia. Low testosterone can affect sex drive, energy, cardiac health and more. When used consistently and correctly, a DHT blocker can take a minimum of three months and a maximum of six to seven to show results. While your hair is unlikely to look the same as it did a few decades ago, targeting the hormonal imbalance will slow down hair loss, improve hair thickness, and promote more even coverage significantly. Synthetic testosterone takes on several forms that can be used to target hair loss.
Overall, testosterone is one of the most important hormones in the human body. All of our content is written by people with a strong science background, including medical researchers. Biotin also helps boost and maintain levels of keratin, a type of protein present in your hair, nails, and skin.
Normal female levels range from 15–70 nanograms per deciliter (ng/dL), whereas male levels typically range from 280–1,100 ng/dL. Hormone levels in the body vary from day to day and also throughout the course of the day. Hair grows at a rate of around half an inch per month for two to six years before stopping and falling out, after which new hair grows in its place.
While testosterone and DHT do play a role in hair loss, it's crucial to consider these other factors and hormonal imbalances that can contribute to the overall complexity of this condition. The Rock, Vin Diesel, and Jason Statham make bald look good, but plenty of guys are worried about hair loss—and whether levels of testosterone plays a role. Bamboo hair happens when your individual hair strand surfaces look thin, knotty, and segmented, rather than smooth. It’s a common symptom of the condition known as Netherton syndrome, a genetic disorder that results in excessive skin shedding and irregular hair growth. But minoxidil can also help promote hair growth when it’s applied topically to your scalp.
Testosterone and DHT
According to the latest clinical data, men are supposed to have total testosterone levels in the 300 – 1,200 ng / dl range (or nanograms per deciliter). In conclusion, while testosterone itself does not directly cause hair loss, its derivative DHT and the use of TRT or anabolic steroids can impact hair loss in susceptible individuals. It is crucial to understand that it is not testosterone itself that causes hair loss, but rather DHT (aka dihydrotestosterone). Our team of experts has analyzed all of the latest scientific studies on testosterone and hair loss, to give you a comprehensive answer on this important topic. This means you are getting science-based information that you can trust. Keep reading to learn more about what the clinical data says about testosterone and TRT, and it’s overall impact on hair loss.
A specific hormone called dihydrotestosterone (DHT) plays a major role in hair growth and loss. DHT is not the same as free testosterone, the form of T that helps you build muscle and regulates your sex drive. DHT also plays a role in some of the same sexual functions and physiological processes as testosterone, but it’s actually much stronger. DHT can bind to an androgen receptor longer, increasing the impact of testosterone production throughout your body. There are treatments meant to slow the onset of male pattern baldness by specifically targeting DHT.
Meaning, testosterone encourages hair growth in certain places while limiting it in others. Symptoms of excessive testosterone levels in relation to hair loss may include increased body and facial hair growth, acne, oily skin, changes in voice pitch, and increased muscle mass. However, it is important to note that these symptoms may also be attributed to other underlying medical conditions and should be assessed by a healthcare professional. Finasteride works by inhibiting the enzyme that converts testosterone into DHT.
Let’s discuss how DHT works, how DHT relates to your hair and to testosterone, and what you can do to stop, or at least delay, male pattern balding. Sex hormones in the body are believed to be the most significant underlying factor behind male pattern hair loss. One of them is that men with MPB are more virile and have higher levels of testosterone. Men with MPB may actually have lower circulating levels of testosterone but higher levels of the enzyme that converts testosterone to DHT.
B vitamins are vital in maintaining the health or your hair and scalp. Lack of these vitamins can reportedly result in hair thinning and eventually even hair loss. B vitamins may not be able to restore hair growth, but they can prevent hair loss. Thinning occurs over the top of the scalp in a “Christmas tree” pattern, but the front hairline doesn’t recede.
This process, known as androgenetic alopecia or male/female pattern baldness, is more common in individuals with elevated testosterone levels. As women go through menopause, the body decreases the production of female expression hormones like estrogen, increasing the production of androgens, such as testosterone. When testosterone levels increase in the body, DHT levels increase as well. The same applies to testosterone supplements, which raise DHT levels and have additional side effects, including acne breakouts, chest hair growth, male pattern baldness, and lowering the voice.
Among genetically predisposed individuals, androgenetic alopecia is characterized by an androgen-responsive hair loss. In vitro, testosterone and estrogen inhibit hair growth, suggesting that scalp hair growth may be controlled by these sex hormones. Hormone imbalance can affect a patient’s day-to-day ability to function at their highest capacity. The many side effects of experiencing low testosterone levels (or “low T”) include loss of muscle mass, weight gain, erectile dysfunction, fatigue, low sex drive, and even depression. As men age, testosterone production naturally decreases and can affect body and facial hair growth.
