Monitoring hormone levels and adjusting the treatment plan accordingly can help mitigate any potential impact on hair loss while balancing the desired benefits of TRT. Aging, for instance, plays a significant role as hair follicles naturally become more susceptible to the effects of hormones over time. During male fetal development, DHT plays a vital role in the development of male external genitalia. However, at puberty, it is involved in the development of the prostate and contributes to the male pattern of hair growth. Among these is the potential side effect of hair loss, otherwise known as balding, a condition wherein the individual’s hair follicles located on their scalp will begin to lose their function, no longer producing hair. Age, stress, and other factors can influence whether you experience hair loss.

Elevated levels of testosterone can lead to an increase in the production of dihydrotestosterone (DHT), a hormone known to cause miniaturization of hair follicles, leading to hair thinning and eventual hair loss. In addition to medication, lifestyle changes can also play a role in managing excessive testosterone levels and preventing hair loss. Regular exercise, stress reduction techniques, and a healthy diet can all contribute to hormonal balance and overall well-being. For example, exercising regularly can help reduce stress levels and increase levels of endorphins, which are known to have a positive effect on hormonal balance. Similarly, a diet rich in fruits, vegetables, and whole grains can provide the necessary nutrients to support healthy hair growth. Hair loss can be caused by a variety of factors, including hormonal imbalances.
Can Testosterone Cause Female Hair Loss?
It’s not the amount of testosterone or DHT that causes baldness; it’s the sensitivity of your hair follicles. The AR gene makes the receptor on hair follicles that interact with testosterone and DHT. If your receptors are particularly sensitive, they are more easily triggered by even small amounts of DHT, and hair loss occurs more easily as a result. Dutasteride is a 5-alpha-reductase inhibitor that binds both types I and II enzymes.
What You Need to Know About DHT and Hair Loss
At the scalp follicle, estradiol has been reported to induce aromatase activity (Hoffmann et al., 2002). Another supporting observation is that in the frontal hairline of women, which tends to be spared with FPHL, there is a higher level of aromatase enzyme when compared with the rest of the scalp (Levy and Emer, 2013). This variation in hair loss could be the result of locally increased levels of estradiol or decreased levels of testosterone and DHT that is secondary to greater amounts of conversion. HRT involves the use of hormones to balance the body's hormonal levels. In the case of excessive testosterone levels, HRT may include the use of anti-androgens, which are medications that block the effects of testosterone.
Testosterone increases bone density and tells the bone marrow to manufacture red blood cells. Men with very low levels of testosterone are more likely to suffer from bone fractures and breaks. The body has a system for controlling testosterone, sending messages through hormones and chemicals that are released into the bloodstream. In the brain, the hypothalamus tells the pituitary gland how much testosterone is needed, and the pituitary relays that information to the testicles.
What are the effects of abnormally high testosterone levels on hair growth and retention?
Testosterone replacement therapy (TRT) and the use of anabolic steroids can also influence hair loss due to their impact on testosterone and DHT levels. Men with higher testosterone levels tend to have higher levels of DHT, so it can be argued that higher testosterone levels “indirectly” cause hair loss. 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. There is some evidence of a link between baldness and prostate cancer and other diseases.
There are treatments meant to slow the onset of male pattern baldness by specifically targeting 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. While testosterone itself is not the direct cause of hair loss, its conversion to DHT is a critical factor. The impact of DHT on hair follicles varies among individuals, largely due to genetic differences in DHT sensitivity. This article aims to unravel this relationship’s complexities, discover the science behind hair growth and loss, and examine how testosterone plays a part.

Finasteride is significantly teratogenic and has been shown to cause feminization of male fetuses (Bowman et al., 2003) as well as sexual side effects, depression, headache, nausea, and hot flashes (Varothai and Bergfeld, 2014). Studies that use low doses (1 mg daily) showed no significant benefit (Kim et al., 2012, Price et al., 2000). However, one study of 37 premenopausal women who were taking a 2.5-mg dose of finasteride daily with an oral contraceptive pill showed improvement of hair loss in 62% of patients (Iorizzo et al., 2006).
When testosterone levels are excessively high, it can disrupt the balance of hormones and potentially impact hair growth. Female-pattern baldness typically starts with scalp hairs becoming progressively less dense. Many women first experience hair thinning and hair loss where they part their hair and on the top-central portion of the head. 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. Dr. Jae Pak specializes in hair transplantation, a procedure that can be a viable solution for those suffering from diagnosed hormonal hair loss.
In this guide we cover everything you need to know about testosterone and hair loss, including your treatment options if you are already have a receding hairline (or worse!). Other methods may include the more regular occurrence of exercise in the patient’s lifestyle, which will improve blood flow to the scalp and therefore also improve hair follicle health. This may also be combined with a proper diet and adequate sleep, all of which are conducive to proper skin and hair function. According to Agbai, genetics, hormonal shifts, stress, underlying medical conditions, nutritional deficiencies, and scalp inflammation are notable factors. Luckily, hair loss due to thyroid conditions often reverses itself over time if healthy hormone levels are both restored and maintained. While the exact link between testosterone and hair growth is unknown, there is no doubt that testosterone plays a role in stimulating hair growth.
With more testosterone, aromatase is able to increase estrogen through the aromatization of testosterone. An interesting aspect of testosterone is that it is naturally converted into estrogen through molecules known as aromatase. Aromatase is an enzyme that initiates the aromatization of testosterone which results in the formation of estrogen. Unlike muscle atrophy, testicular atrophy can occur without you even knowing it’s occurring as it is not immediately noticeable.
The first step to finding out if you have low testosterone is to discuss your symptoms with a knowledgeable medical provider. All that said, it might be a good idea to familiarize yourself with the symptoms of low testosterone in women. It’s not something many women think of when they see physical changes or are not feeling well. It would be highly unusual for a mild, subclinical thyroid imbalance to cause this type of diffuse hair loss. When it comes to treating low testosterone, the most common way is a cream applied to the upper arm, but injectable or pill forms of testosterone are also available.
Interestingly, science suggests that it is not necessarily the amount of androgens that is the determining factor regarding your hair loss, but instead, the sensitivity to the androgens. 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. In the body, testosterone is converted to DHT or dihydrotestosterone by an enzyme called 5-alpha-reductase or 5-AR.
The exact causes of low testosterone can vary on a case by case basis, with most ordinary individuals experiencing a minor decline in their total serum testosterone production on a year by year basis after approximately thirty years old. Another 5-alpha reductase inhibitor called dutasteride (Avodart) is currently being looked at as a potential treatment for MPB. Most testosterone is bound to sex hormone-binding globulin (SHBG) protein and isn’t active. If you have a low level of SHBG, you may have a high level of free testosterone in your bloodstream.
By reducing levels of DHT in the body, finasteride can help prevent the miniaturization of hair follicles and potentially stimulate hair growth. It is important to note that finasteride is generally prescribed for men, as excessive testosterone levels are more common in males. Dihydrotestosterone (DHT), a derivative of testosterone, plays a pivotal role in hair loss, particularly in male pattern baldness. High levels of DHT can shrink hair follicles and shorten the hair growth cycle, leading to thinner, shorter hairs and eventually causing the follicles to stop producing hair altogether. People experiencing female pattern baldness may also notice a general thinning of hair on the top of your head, but hair loss typically won’t occur on the front of your scalp, per Harvard Health.
One common assumption among patients is that high testosterone levels directly cause hair loss, but the true answer to the question is more complex. High levels of testosterone in the body may result in an increased production of DHT, which can accelerate the process of hair loss for patients genetically susceptible to balding. While high testosterone or DHT levels do not directly cause hair loss, high DHT levels have been linked with conditions such as prostate cancer and benign prostatic hyperplasia. Hair transplantation is another option for more severe cases of hair loss. This involves removing hair follicles from one part of the body, typically the back of the scalp, and transplanting them to areas of thinning or balding.
