research IMPROVEMENT OF ALOPECIA AND DECREASES IN HAIR CORTISOL AND DIHYDROTESTOSTERONE CONCENTRATIONS AFTER THE TOPICAL USE OF PLANT EXTRACTS IN MEN WITH ANDROGENETIC ALOPECIA

August 2021 in “Asian Journal of Pharmaceutical and Clinical Research”

In this randomized trial, a solid shampoo formulated with plant extracts was more effective than placebo in improving androgenetic alopecia and reducing hair cortisol and DHT concentrations in men.

research The Comparison of Trichoscopic Findings in Female Pattern Hair Loss (FPHL) and Chronic Telogen Effluvium (CTE) in Female Patients

December 2021 in “Journal of pharmaceutical research international”

This study found that trichoscopy can effectively differentiate female pattern hair loss from chronic telogen effluvium based on specific features like hair shaft diameter variability and density differences, aiding in targeted treatment planning.

research Perception of Baldness and Hair Density

16 citations , January 2002 in “Dermatology”

This study found that the parietal/occipital hair density ratio decreases significantly only when baldness is visibly present, making it no better than the Hamilton/Norwood scale for assessing baldness severity.

research Heat stress decreased hair follicle population in rex rabbits

10 citations , December 2018 in “Journal of animal physiology and animal nutrition”

This study found that heat stress in rex rabbits decreased hair follicle density and suppressed related signaling pathways, potentially affecting hair follicle development.

research Evaluation of Hair Density and Hair Diameter in the Adult Thai Population Using Quantitative Trichoscopic Analysis

31 citations , February 2020 in “BioMed Research International”

This study found that in the Thai population, hair density varies by scalp location and decreases with age, and that Asians generally have lower hair density compared to Caucasian and African populations.

community For how many years did finasteride allow you to maintain the same hair density?

in Finasteride/Dutasteride 5 upvotes 1 month ago

Finasteride has helped users maintain hair density for varying durations, with some experiencing effectiveness for up to 20 years, while others noticed a decline after 4 to 6 years and switched to dutasteride. Users also reported occasional shedding and some switched treatments when effectiveness decreased.

community Been on treatment for 2 years, hair density is just getting worse

6 upvotes 1 year ago

The user has been using finasteride, dutasteride, minoxidil, and RU58841 for hair loss but is experiencing worsening hair density despite treatment. They are frustrated and confused as their hairline remains unchanged, but the overall hair thickness has decreased significantly.

community Topical Melatonin, Hair Loss/Growth, and Seb Derm (Seborrheic Dermatitis)

13 upvotes 3 years ago

Topical melatonin was found to significantly increase hair density and decrease scalp conditions like seborrheic dermatitis. The user is considering using it alongside finasteride and oral minoxidil for treating hair loss and scalp health.

community Dutasteride + oral minoxidil: strong regrowth by Jan 2026, then mid-scalp density loss without current shedding

3 upvotes 4 months ago

The user experienced hair regrowth with dutasteride and oral minoxidil from October 2025 to January 2026, but mid-scalp density decreased afterward despite continued treatment. Ketoconazole improves scalp condition, but stopping it worsens hair appearance.

community Alfatradiol causing shedding ?

1 upvotes 1 year ago

The user experienced a sudden decrease in hair density after starting alfatradiol while already using finasteride. Another user mentioned that initial shedding can occur with hair loss treatments, but it may not last long.

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 Osteopontin

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

learn Overview

learn Fluridil

a topical anti-androgen with less systemic involvement

learn Stemoxydine

Can stemoxydine help improve hair density in both men and women? Stemoxydine is a cosmetic ingredient, not an approved hair loss drug, and the manufacturer's three-month trials enrolled men only, reporting a small increase in measured hair density. One small uncontrolled study that included women reported improvement in both sexes but more in men, so a benefit for women is not established.
Is stemoxydine effective for early-stage thinning and alopecia? Stemoxydine may help improve hair density in early-stage thinning and alopecia.

learn Hair Transplant

Does a hair transplant increase hair density? A hair transplant can improve density, but results vary by individual factors.

learn Dutasteride

Dutasteride side effects: what the label and studies actually report The Avodart label reports impotence in 4.7% and decreased libido in 3.0% of men in the first six months (1.7% and 1.4% on placebo), with new reports falling after month six; those figures come from BPH trials in older men, and the hair-loss trials in younger men run only six months. The label and studies also flag a PSA drop of about half, a small rise in high-grade prostate cancer in one trial, an observational link to depression, and sexual effects that the label says may persist after stopping.
