research Physiology and Medical Treatments for Alopecia

8 citations , April 2020 in “Facial Plastic Surgery Clinics of North America”

This abstract explains that androgenetic alopecia, a common hair loss disorder influenced by genetics and hormones like dihydrotestosterone, has FDA-approved treatments including minoxidil, finasteride, and photolaser therapy, but its genetic basis and susceptibility to environmental factors remain complex.

research Frontiers in the physiology of male pattern androgenetic alopecia: Beyond the androgen horizon

July 2025 in “Physiological Reviews”

This study presents male pattern androgenetic alopecia (mpAGA) as a natural physiological process involving reversible transformation of hair follicles, but notes unresolved links with androgen mechanisms and highlights potential research avenues beyond androgen receptor signaling for treatment exploration.

research Hair Physiology (Hair Growth, Alopecia, Scalp Treatment, etc.)

1 citations , January 2017 in “Elsevier eBooks”

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

research Melatonin and hair physiology: reasons and clinical efficacy data as a topical treatment of androgenic alopecia

March 2014 in “Medicina cutánea ibero-latino-americana”

This review discusses the role of melatonin in skin and hair physiology, highlighting clinical evidence for its potential benefits in treating androgenetic alopecia, but does not report new results.

research The Effect of Parathyroid Hormones on Hair Follicle Physiology: Implications for Treatment of Chemotherapy-Induced Alopecia

15 citations , January 2015 in “Skin Pharmacology and Physiology”

This study indicates that targeting the PTH/PTHrP receptor may potentially stimulate hair growth, particularly for chemotherapy-induced alopecia, as observed in hairless and cyclophosphamide-treated mice.

community My Theory Of Androgenic Alopecia

16 upvotes 10 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.

community My understanding of how androgenetic alopecia works (plus FIN and DUT)

18 upvotes 4 years ago

Androgenetic alopecia is affected by scalp DHT levels, not sensitivity, with treatments like finasteride and dutasteride aiming to optimize these levels. Personalized DHT management is crucial for effective hair growth.

community Androgenetic alopecia is a skin disease: DHT-mediated skin disorders

63 upvotes 2 years ago

Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.

community Finasteride success for androgenic alopecia by a 27M physician (NO PICTURES)

4 upvotes 10 years ago

A 27-year-old male physician improved hair density using minoxidil 5% foam and finasteride 1mg every other day, with initial sexual side effects that subsided. He recommends trying finasteride for a year but warns against dutasteride due to potential liver effects.

community My 15+ Year Hair Loss Journey: DUPA, Recurrent Alopecia Areata, & different dosages of Min / Fin topicals - Advice needed on next steps.

4 upvotes 2 weeks ago

The user has been managing hair loss for over 15 years, using treatments like Minoxidil, Finasteride, and corticosteroids, while experiencing side effects and recurrent Alopecia Areata. They seek advice on progression and potential underlying conditions, questioning if their hair loss is due to an autoimmune issue beyond typical patterns.

learn PP405

mitochondrial pyruvate carrier (MPC) inhibitor by Pelage in early trials

Got small bald patches they say are from stress? PP405 sprays could help bring them back to life. PP405 is an experimental topical gel from Pelage Pharmaceuticals that inhibits the mitochondrial pyruvate carrier; its registered Phase 2 trial (NCT06393452) tested it once daily in 78 adults with pattern hair loss, for safety and tolerability. It is not approved, not for sale, and has not been studied in alopecia areata or stress-related shedding.

learn Microneedling

technique to create small wounds in skin to activate collagen production and hair growth

learn Osteopontin

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Exosomes

Microscopic delivery system that sends growth-promoting signals to hair follicles

learn Estradiol

an estrogen promoting hair regrowth more commonly used in women

learn Finasteride

Does hair strand thickness decrease in men with androgenic alopecia? Can finasteride help restore it? Androgenic alopecia thins hair strands by miniaturizing follicles. The pivotal finasteride trials (1,553 men, 1 mg/day, two years) report increased hair counts and improved assessed appearance, but they measured density, not the diameter of individual strands, so the effect on thickness itself is not established.

learn GHK-Cu

Heard alopecia areata leaves scar-like spots? Some peptides are helping those areas regrow hair. Alopecia areata patches usually still have living follicles. Peptides are being studied as a possible add-on, but the evidence is small and early. See a dermatologist for treatment.

learn TDM-105795

What types of alopecia or hair loss conditions might TDM-105795 be designed to target based on current research? TDM-105795 may target non-scarring alopecia, particularly androgenetic alopecia.

learn Alfatradiol

Alfatradiol: Can it help if my hair loss is linked to DHT? The one randomised trial of topical alfatradiol — in 103 women — found hair thickness and density essentially unchanged after six months, while minoxidil improved both; its authors credited alfatradiol with slowing hair loss rather than regrowing hair. Laboratory work supports a local effect on follicular DHT, but no controlled trial in men appears to have been published.
