research Determination of Solute Diffusion Properties in Artificial Sebum

6 citations , May 2019 in “Journal of pharmaceutical sciences”

This study found that diffusion coefficients of chemicals in artificial sebum are significantly higher than those in stratum corneum lipids, suggesting the hair follicle may significantly contribute to transdermal permeation.

research Changes in serum free testosterone, sleep patterns, and 5‐alpha‐reductase type I activity influence changes in sebum excretion in female subjects

10 citations , August 2014 in “Skin research and technology”

This study found that variations in sleep patterns, free testosterone, and 5-alpha-reductase type 1 activity are associated with changes in sebum excretion in women, which may contribute to variability in acne studies.

research Sebum Production

1 citations , September 2016 in “Springer eBooks”

This article reports no new data; it describes the role of sebum in influencing the skin microbiome and epithelial tissues and discusses its altered composition during transit through the sebaceous duct.

research Normal Fur Development and Sebum Production Depends on Fatty Acid 2-Hydroxylase Expression in Sebaceous Glands

40 citations , June 2011 in “Journal of biological chemistry/The Journal of biological chemistry”

This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

research (1R,2S)-4-(2-Cyano-cyclohexyl-oxy)-2-trifluoromethyl-benzonitrile, a potent androgen receptor antagonist for stimulating hair growth and reducing sebum production

14 citations , August 2007 in “Bioorganic & Medicinal Chemistry Letters”

This study reported that the compound (1R, 2S)-4-(2-cyano-cyclohexyl-oxy)-2-trifluoromethyl-benzonitrile effectively stimulated hair growth in mice and reduced sebum production in hamsters.

community DHT Itch and Oily Scalp Explained (and how to fix it)

90 upvotes 3 months ago

Malassezia overgrowth can worsen oily scalp and inflammation, contributing to hair loss. Treatments include antifungal shampoos, C6/C8 MCT oil, low-dose isotretinoin, finasteride, and dutasteride.

community Are we underestimating systemic absorption with homemade/generic Topical Fin? (HPCH vs. PG/Ethanol formulations)

5 upvotes 8 months ago

Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

learn Bimatoprost

Can a lash-growth serum like bimatoprost actually work for your scalp? Bimatoprost (Latisse) is FDA-approved only for eyelashes, not the scalp. In the larger of two Allergan phase 2 scalp trials, every bimatoprost formulation gave smaller hair-count gains than minoxidil 5%; the results were posted to ClinicalTrials.gov but never published in a journal, and scalp use remains off-label and experimental.

learn Exosomes

Are exosomes applied as a serum, an injection, or combined with other hair treatments? Clinics offer exosomes as scalp injections, as serums applied after microneedling, or combined with PRP. No exosome product is FDA-approved, and no reliable evidence shows that any of these methods works.

learn Rapamycin

Are there any visible side effects when using rapamycin cream or serum on the scalp? No study has tested rapamycin on the scalp; in facial trials skin reactions were common (64% vs 29% placebo; Aitken et al. 2023, PMID 37463422).
