Androgenetic Alopecia: A Guide to Pattern Hair Loss
Table Of Content
The androgens are a critical factor that leads to the gradual conversion of terminal hairs into intermediate and vellus hairs, resulting in the gradual hair thinning and hair loss seen in patients with AGA (Lolli et al., 2017). Different types of gut microbiota can produce enzymes essential for androgen metabolism, facilitating the synthesis and alteration of androgens. The microbial-mediated degradation of testosterone has been witnessed across various environmental contexts. For instance, Actinobacteria and Proteobacteria possess the capability to break down androgens (Qi et al., 2021). Additionally, Clostridium scindens, harboring the 20α-hydroxysteroid dehydrogenase (HSDH) enzyme in its genome, is a human gut microbe with significant potential to convert glucocorticoids into androgens (Ridlon et al., 2013).
Male Pattern Baldness
It is worth noting that this method is unlikely to benefit or help people with scarring alopecias. Traction alopecia results from too much pressure and tension on the hair, often from wearing it in tight styles, like braids, ponytails, or buns. The main symptom of alopecia is losing more hair than usual, but this can be harder to identify than you might think.

Scarring alopecia is the result of active destruction of the hair follicle. Several hair disorders show a biphasic pattern in which nonscarring alopecia occurs early in the course of the disease, and then scarring alopecia and permanent hair loss occurs as the disease progresses. Scarring alopecias can be subdivided further into primary forms, where the target of inflammation is the follicle itself, and secondary forms, where the follicle is destroyed as a result of nonspecific inflammation (see table Some Causes of Alopecia). Alopecia causes vary, and for androgenetic alopecia specifically, various risk factors from genetics to age could be the root of your symptoms. Unfortunately, scientists and doctors don’t know how much hair an individual with androgenetic alopecia will lose, so if you’re facing this condition, it’s hard to know what the fate of your hair will be, notes StatPearls. You can also practice healthy hair habits, such as avoiding tight hairstyles, limiting the use of hot hair tools, and gently cleansing hair, advises the AAD.
HORMONAL THERAPIES
The role of androgens in women’s hair loss is less well known, she adds. It’s also important to see a board-certified dermatologist if you’re worried that you’re losing your hair. Treatments for androgenetic alopecia, which include both topical and oral medications that stimulate hair growth and slow hair loss, are often most effective when started early, according to the AAD. What’s more, because of the range of treatments available, you can work with a dermatologist to find what’s right for you. There are many innovative treatments for AGA and that landscape is constantly evolving. Some treatments are too new to report or advocate a particular brand or device, which lies beyond the scope and interest of this overview page.
Alternative therapies
Spironolactone exhibits a very weak partial agonist toward the androgen receptor. Its primary mode of action involves blocking the more potent DHT and free testosterone from binding to the androgen receptor, physiologically behaving like a direct antagonist. Additionally, spironolactone inhibits androgen synthesis and enhances the conversion of testosterone to estradiol. These reports by the journal were only reflective of unstructured telephone calls and were not reflective of a controlled study. Even though persistent side effects are most likely quite uncommon, it is important to discuss this with a patient considering this therapy.
Another example is that in men, early androgenetic alopecia is defined as occurring before 30 years and is seen as the male phenotypic equivalent to polycystic ovarian syndrome. A move, having a baby, and psychological stress can all cause a different type of hair loss, called telogen effluvium (TE), notes research. This hair loss is actually hair shedding that occurs all over your head. And while stress is not a cause of androgenetic alopecia, TE can unmask male or female pattern baldness, bringing it to light for the first time. Androgenetic alopecia, also called male or female pattern hair loss, is the most common cause of hair loss. Genetics and age are both risk factors for this type of hair loss, and the condition may also be a sign of more serious health issues.

In women, the diagnosis usually requires more complex diagnostic evaluation. Treatment is continued indefinitely because, once treatment is stopped, hair loss resumes. The most frequent adverse effects are mild scalp irritation, allergic contact dermatitis2, 3). In contrast with LLLT that delivers a single, collimated wavelength of light, light‐emitting diode (LED) devices may emit a small band of wavelengths.
“These are the hairs in front and top of the scalp, while the hair on the sides and back of the head are not,” he says. For example, if someone is showing thinning in the crown but has completely lost the frontal half of the scalp where there is no more hairline, medical therapy can be used to restore the crown and surgery can be used to restore the entirely lost hairline. Oral minoxidil may bypass some of the limitations of topical minoxidil in that it does not require activation in the scalp skin of minoxidil into its active metabolite, minoxidil sulfate, which can be diminished in some individuals’ scalps. However, oral minoxidil may have more potent adverse events, like lower blood pressure, heart palpitations (feeling the heart beat too fast), swelling in the legs, or more facial/body hair growth, than topical administration.
What Are the Treatment Options for Androgenetic Alopecia?
Regardless, for both men and women, hair loss can be difficult to endure psychologically. Androgenetic alopecia has been linked to depression and anxiety in women, research shows. Men may also be extremely unhappy with their hair loss and less accepting of the changes than people may assume them to be, according to the American Hair Loss Association. Early treatment of a receding hairline (frontal fibrosing alopecia) might help avoid significant permanent baldness. The cause of this condition is unknown, but it primarily affects older women. Male-pattern baldness typically appears first at the hairline or top of the head.
There are effective treatments that can help regrow hair and stop further hair loss. There are many different types of hair loss, but the most common for women is female pattern hair loss. Known as androgenic alopecia, the condition may run in families because genetics are believed to play a role.
Finasteride, marketed under the brand name Propecia by Merck, has been FDA-cleared for male AGA since 1997 at a 1 mg dose and since 1992 at a 5 mg dose to treat benign prostatic hyperplasia. Since 2013, Merck has lost its patent for Propecia, and generic versions of its oral medication can now be obtained without the need to cut a 5 mg pill that was more common practice prior to that time to save on medication costs. Low-level laser therapy is of unproven benefit in pattern balding; one device has been approved by the FDA for marketing. Keep in mind that the effectiveness of these treatments can vary from person to person. To determine the best approach for your specific needs, it’s important to consult with a healthcare professional who can provide personalized guidance. Maintaining consistency with these treatments is crucial, as many require ongoing use to achieve and sustain positive results.
In the type of patchy hair loss known as alopecia areata, hair loss occurs suddenly and usually starts with one or more circular bald patches that may overlap. Find out how nutrient deficiencies, COVID-19, and autoimmune conditions like alopecia... Variation of the androgen receptor (AR) gene (though there may be other genes involved, as well) is the known gene that sets the stage for hair loss, according to the National Library of Medicine. There are many scales to define female hair loss but the most commonly used one is the Ludwig scale which defines mild (Ludwig 1), moderate (Ludwig 2), and severe (Ludwig 3) hair loss (Figure 9). Spironolactone (Aldactone), which is taken in a pill, seems to work best in women who haven’t yet reached menopause.
A familial predisposition towards androgenetic alopecia exists, with sons having 5 to 6 times higher relative risk if their fathers experienced balding. The International Society of Hair Restoration Surgery (ISHRS) is a global non-profit medical association and the leading authority on hair loss treatment and restoration. With more than 1,100 members throughout 70 countries worldwide, the ISHRS is dedicated to achieving excellence in patient outcomes by promoting the highest standards of medical practice, medical ethics, and research in the medical hair restoration industry. Platelet-rich plasma (PRP) therapy involves taking concentrated growth factors from extracted blood and re-injecting them back into the scalp to help grow hairs non-surgically. There are many protocols of how often to perform the procedure as well as different machines used to purify and concentrate the growth factors.
