Your healthcare provider may recommend monitoring your hormone levels, including testosterone, before and during minoxidil treatment to ensure that there are no significant changes or adverse effects. In a study published in the Journal of the American Academy of Dermatology, researchers assessed the effects of topical minoxidil on hormone levels, including testosterone, in men with androgenetic alopecia. One area of interest is the impact of minoxidil on testosterone levels, as testosterone plays a crucial role in various physiological processes, including hair growth and overall health. A longer duration would have provided better opportunity to assess the full potential of minoxidil monotherapy to promote facial hair growth. Despite its unclear mechanism, the efficacy of topical minoxidil on scalp hair growth is well established in cisgender men and women.
Since 1997, topical minoxidil has been available over-the-counter and, whilst oral minoxidil has adverse cardiovascular effects, side effects of topical administration have so far been limited to reversible hypertrichosis, pruritis and local skin irritation (16, 18–20). The other was a randomized, double-blinded, placebo-controlled trial of 3% minoxidil solution involving 48 Thai men, and which demonstrated a significant increase in facial hair counts after 16 weeks of treatment (14). Currently, however, there are no recommended treatments used to specifically stimulate facial hair development in transmasculine individuals. The majority of these individuals have a transmasculine identity, and testosterone is frequently used to induce reversible changes such as android fat redistribution and increased muscle mass, as well as irreversible changes such as a deeper voice and increased facial/body hair growth (10, 11). While testosterone therapy in transgender males is generally effective in inducing masculinization, some adolescents encounter barriers to accessing such treatment or may not wish to experience all the changes that usually accompany testosterone. Our specialists confirm that Minoxidil does not significantly affect female testosterone levels either. While testosterone is a primary factor in male hair loss, women also use Minoxidil to treat thinning hair.
This shrinkage results in hair thinning and eventual hair loss. In men, testosterone is closely linked to male pattern baldness. It plays a key role in many bodily functions, including muscle mass, bone density, and hair growth. This is one of the reasons why Minoxidil is often recommended as a safer, non-hormonal treatment option. Bio-Pilixin® is a clinically tested, drug-free answer to your hair loss woes.
Firstly, one limitation of this study is that minoxidil was used as a stand-alone treatment for only 3 months before testosterone was started. The observation in our case that areas of skin not contacted by minoxidil demonstrated increased hair growth was unexpected and implies systemic absorption, as has been described by some (23) but not others (17). The mechanism of minoxidil action on hair growth is unclear but has been postulated to act via potassium channels (21) or by causing an influx of intracellular calcium (22).
Some people speculate that Minoxidil affects sexual health, masculinity, or libido due to its supposed link to testosterone. For those who experience signs of low testosterone, consider adjusting medications under a doctor's supervision. However, the effects seem to be modest and reversible.
Gender affirming care for TGD youth includes social and psychological support and, in some cases, medical interventions. A total score of ≥8 is considered elevated for a Caucasian individual assigned female at birth. Modified Ferriman-Gallwey score evaluation before and after 3 months of minoxidil monotherapy. With his pediatrician’s agreement, he subsequently purchased minoxidil (5% lotion) and applied 1 mL twice daily to the beard area. No signs of male pattern baldness, acne or hirsutism (see Table 2 for modified Ferriman Gallwey score evaluation at baseline). However, due to legal requirements in Australia at the time, he was required to obtain Family Court approval to initiate therapy with testosterone.|The concomitant use of testosterone in these informal reports, however, makes it difficult to know whether it was minoxidil, testosterone or their combination that was responsible for apparent improvement. The choice of medical interventions varies and is often influenced by the desire to acquire particular masculine characteristics and/or avoid certain side effects. Trans and gender diverse (TGD) individuals have a gender identity that differs from their sex assigned at birth. Many individuals worry about the possibility of sexual side effects, including erectile dysfunction, low libido, or ejaculation disorders, when using Minoxidil.|These instances are very uncommon and do not seem to be connected to changes in testosterone levels. A common question is whether Minoxidil affects female hormones, particularly testosterone. According to dermatologists, Minoxidil’s effects are topical and not systemic, meaning it does not affect testosterone production or alter its function in the body. Minoxidil works locally on the scalp, targeting hair follicles without entering the bloodstream significantly. One of the most common concerns people have when considering Minoxidil is whether it has any impact on testosterone levels. This condition is influenced by both genetic predisposition and hormone levels, particularly testosterone.|These are more likely in people with naturally low blood pressure, since Minoxidil is a vasodilator (it relaxes blood vessels). Minoxidil doesn’t increase testosterone, reduce it, or significantly influence how it’s processed in the body. Other treatments, like Finasteride (Propecia), work by reducing the amount of DHT in the body. DHT is a by-product of testosterone, converted in the body by the enzyme 5-alpha-reductase. Studies suggest that around 60–70% of men see improvement in hair density with consistent use. This supports healthier follicle function and, in many cases, leads to visible regrowth.|In such cases, minoxidil may be a means to accelerate and/or augment facial hair growth. We believe that this is the first reported use of minoxidil for this purpose in the medical literature, and the facial hair development that occurred within just three months was at least as good as what we have previously observed using testosterone over a similar time frame. At the time of writing, he continues to intermittently apply minoxidil to aid further facial hair growth, targeting areas where he feels additional growth is needed. One trial examined use of topical 2.5% testosterone gel applied for six months to the beard area in men with thalassemia major – since male hypogonadism is a known complication of this condition – and reported a significant increase in facial hair density compared to those who received placebo gel (13). Given its long-standing use and safety record in the management of alopecia, minoxidil might thus represent a useful treatment option for trans males who desire an increase in facial hair. In this case, minoxidil was applied regularly to the lower face and, after three months of treatment, he developed obvious pigmented facial hair that was sufficient to help him avoid being misgendered.}
