Hormonal Activity in Commonly Used Black Hair Care Products: Evaluating Hormone Disruption as a Plausible Contribution to Health Disparities

research Hormonal activity in commonly used Black hair care products: evaluating hormone disruption as a plausible contribution to health disparities

25 citations , May 2021 in “Journal of exposure science & environmental epidemiology/Journal of exposure science and environmental epidemiology”

This study found that hair products commonly used by Black women exhibited hormonal activity, which could impact health outcomes and contribute to health disparities.

research Hormonal control of 5.ALPHA.-reductase activity in hamster sebaceous glands.

4 citations , January 1982 in “Endocrinologia Japonica”

This study found that castration increased 5 alpha-reductase activity in the sebaceous glands of male hamsters, but administering testosterone propionate or 5 alpha-dihydrotestosterone inhibited this effect.

Multiple Readout Assay for Hormonal (Androgenic and Antiandrogenic) and Cytotoxic Activity of Plant and Fungal Extracts Based on Differential Prostate Cancer Cell Line Behavior

research Multiple readout assay for hormonal (androgenic and antiandrogenic) and cytotoxic activity of plant and fungal extracts based on differential prostate cancer cell line behavior

19 citations , August 2014 in “Journal of Ethnopharmacology”

The study created a test that found hormonal and toxic effects in plant and fungal extracts using prostate cancer cells.

Hormonal Parameters in Androgenetic Hair Loss in Males

research Hormonal Parameters in Androgenetic Hair Loss in the Male

21 citations , October 2009 in “Dermatology”

This study found that male pattern hair loss may be associated with differences in serum levels of androstenedione, cortisol, 17 beta-estradiol, and luteinizing hormone, compared to controls.

Clinical Aspects, Pathogenesis, and Therapy Options of Alopecia Induced by Hormonal Therapy for Breast Cancer

research Clinical aspect, pathogenesis and therapy options of alopecia induced by hormonal therapy for breast cancer

2 citations , October 2021 in “Exploration of targeted anti-tumor therapy”

This review describes oncotherapy-induced alopecia in patients receiving hormone therapy for hormone-receptor-positive breast cancer and concludes that topical hormones should not be used due to oncogenic potential.

community Hormonal changes due ejaculation

2 years ago

Avoiding ejaculation may help slow hair loss or promote regrowth by allowing progesterone to build up and decrease DHT production. This is suggested as a strategy for men with a genetic predisposition to hair loss.

community Minoxidil is a 5ar inhibitor according to research

150 upvotes 11 months ago

Minoxidil may inhibit androgen receptors and affect hormonal pathways, potentially explaining its effectiveness in treating androgenetic alopecia (AGA). Users discuss its varying effectiveness on scalp versus facial hair and note fewer side effects with topical use compared to oral.

community Rosemary oil's potency as a dht blocker

in Research/Science 65 upvotes 2 years ago

Rosemary extract showed high inhibitory activity against DHT, similar to finasteride and dutasteride, but the conversation includes skepticism about its effectiveness in humans since the study was done on mice and rosemary oil is often considered ineffective based on personal experiences. Some suggest trying rosemary oil alongside other treatments, while others emphasize the difference between the extract used in the study and the oil.

community What factors cause more regrowth for MTF people with hormone replacement therapy?

6 upvotes 3 years ago

Hair regrowth in transfems is more effective due to hormonal changes, specifically estrogen, which keeps hair in growth phase longer. Treatments mentioned include anti-androgens, sex hormones, and DHT blockers like finasteride.

community Do we know exactly why some people respond so great to dut/fin,min and others dont?

in Research/Science 29 upvotes 1 year ago

Genetic factors, enzyme activity, and DHT sensitivity affect individual responses to hair loss treatments like finasteride, minoxidil, and dutasteride. Starting treatments early can slow hair loss, but results vary among individuals.

learn Bicalutamide

a nonsteroidal anti-androgen, most commonly used orally for women

Why are some women using bicalutamide to fight hormonal hair loss? Bicalutamide blocks androgens, helping women combat hormonal hair loss effectively.

learn Lavender

Is lavender effective for hormonal hair loss or just stress? Lavender may help with stress-related hair loss but has limited evidence for hormonal hair loss.

learn procapil

Want to stop hormonal hair loss without touching your hormone levels? Procapil could block the enzyme doing the damage. Procapil's supplier describes it as inhibiting 5-alpha reductase at the scalp without changing hormone levels, but the published support is cell and animal work plus one small human study of a caffeine-plus-Procapil formula. It is a cosmetic ingredient, not an approved hair-loss treatment, and no trial has compared it with finasteride or minoxidil.

learn Baicapil

Losing hair from hormonal imbalance? Baicapil might block DHT without messing with your hormones. No published study shows that Baicapil blocks DHT — the only data on the ingredient itself is the manufacturer's own unpublished dossier, and the baicalin research behind the claim is cancer cell-line work in which the effect was explicitly independent of the androgen receptor.

learn Adenosine

Adenosine : Can it help if my hair loss is due to a hormonal imbalance like PCOS or DHT? Adenosine may help improve hair growth affected by hormonal imbalances like PCOS or DHT.
