In conclusion, androgenetic alopecia is a common, progressive form of hair loss influenced by genetics and hormones, affecting men and women differently. DHT is often blamed for androgenetic alopecia, commonly known as male or female pattern baldness. 95% of hair loss reported is caused by androgenetic alopecia with the main symptom being gradual thinning of hair. Dysbiosis—microbial imbalance—can trigger scalp inflammation, disrupt hair growth cycles, and exacerbate conditions such as seborrheic dermatitis and folliculitis, all of which can accelerate hair loss. Blood testing is essential because hormonal imbalances involving testosterone, estrogen, or DHT are a common cause of hair loss, particularly androgenetic alopecia. If you have endocrine conditions, scalp disorders, diagnosed hair loss disorders, or a strong family history of androgenetic alopecia, talk with your doctor before using any supplements. have put forward the idea that weight training and other forms of exercise increase hair loss in predisposed individuals. While a 2001 South Korean study showed that most people rated balding men as less attractive, a 2002 survey of Welsh women found that they rated bald and gray-haired men quite desirable.} Plants like Serenoa repens, Panax ginseng, Curcuma aeruginosa, Cucurbita pepo and Trifolium pratense59; palm extract (tocotrienol/tocopherol complex), horsetail and ashwagandha have been reported to treat AGA. Phytomedicine, the use of plant-based products for medicinal purposes, is popular for treating AGA and can be used as a complementary or alternative treatment. Later in 2011, the ARTAS system was also approved to harvest curly hair in black men.52 ARTAS robotic hair transplant is a minimally invasive hair restoration system that uses artificial intelligence technology to restore hair faster and more precisely than traditional hair restoration methods. The transplanted follicles do not miniaturize, grow in groups of 1 to 4 hairs and are harvested as units. However, challenges exist in standardizing treatment parameters, study designs, and assessing long-term outcomes in LLLT studies.50,51 Recent research discovered that finasteride can bind and inhibit phenylethanolamine N-methyltransferase, an enzyme that controls epinephrine production. This helps boost strength, enhance performance, increase muscle growth, and heighten cognition (all things that are well-documented in the research). In that study, participants loaded creatine at 25 g/day for 7 days (with carbohydrate), then took 5 g/day for 14 days. Men may typically start experiencing baldness anywhere between the ages of 20 and 30, which is typically when many people start exercising and using supplements. Additionally, human clinical trials report that low zinc and vitamin E levels are linked with a higher risk of developing alopecia. Deficiencies of key nutrients may also increase hair loss. There was an average 11% improvement in scalp scaling and a reported total hair count increased by 27.6% compared to the placebo. The mechanism is thought to be that the vitamin E helps to reduce lipid peroxidation and oxidative stress in the scalp which is linked with alopecia. Supplementing 400mg of saw palmetto extract reduced hair fall by 29% and increased hair density by 5%, significantly reduced DHT levels following a 4-month study period. In this treatment, a healthcare provider draws your blood, processes it to concentrate the platelets, and injects it into your scalp to promote hair growth. There are several ways to manage and treat male pattern baldness, depending on your preferences and the stage of hair loss. It binds to receptors in the scalp’s hair follicles, especially at the crown and temples, shortening the hair growth cycle and making new hairs thinner and weaker. "Could testosterone replacement speed up male pattern hair loss? Absolutely. But likely it's because you're already genetically predisposed to getting hair loss," says Malik. MALE PATTERN BALDNESS, also known as androgenic alopecia, is something that affects a lot of guys—and there is some evidence in particular to suggest that men undergoing testosterone replacement therapy (TRT) are at a higher risk of hair loss. Other upcoming treatments for AGA include Janus kinase inhibitors, which block the immune system response causing hair loss, and stem cell therapies that stimulate hair growth. Finasteride – a competitive and specific SRD5A2 inhibitor – is an FDA-approved drug used to treat adult men with mild to moderate AGA at an oral dosage of 1 mg/day, thereby decreasing serum, prostate, and scalp DHT by 60% to 70%.33 Finasteride preferentially inhibitions SRD5A2 by forming a stable complex with the enzyme in the presence of NADPH (Fig 4). The SRD5A2 synthesizes DHT by converting testosterone in the presence of NADPH to DHT. In androgen metabolism, SRD5A reduces Δ4,5 bond in substrates using NADPH, for example, SRD5A1 converts testosterone to DHT causing BPH and SRD5A2 is involved in AGA.
