research Preparing the hair follicle canal for hair shaft emergence

5 citations , October 2020 in “Experimental dermatology”

This study reports that during late embryogenesis and early postnatal development, K79-expressing keratinocytes change and die independently of sebaceous glands to form the hair follicle opening, potentially influencing conditions like ingrown hairs or acne.

research Matrix Metalloproteinase-9 Is Involved in the Regulation of Hair Canal Formation

20 citations , September 2010 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study suggests that MMP-9 plays a significant role in extracellular matrix remodeling during hair canal formation in mice, as indicated by delayed hair shaft emergence and hair canal development in MMP-9 knockout mice.

research 176 Hair eruption initiates adverse events of EGFR-targeted cancer therapy

November 2023 in “Journal of Investigative Dermatology”

EGFR-targeted cancer therapy can cause skin issues starting at hair follicles, leading to inflammation.

research 33 Emergency Preparedness in Hair Restoration Surgery

October 2022 in “Hair Transplantation”

This chapter reviews updated Basic Life Support protocols, including the shift to Compression-Airway-Breathing, but offers no new clinical results, emphasizing the need for AEDs in medical offices.

research 785 Single-cell transcriptomic profile of EGFR-deficient epidermal compartments during folliculitis

April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study reported significant transcriptomic changes in keratinocyte and immune cell populations in a mouse model with EGFR-deficient epidermis, suggesting possible targets for mitigating adverse skin events in EGFR-targeted cancer therapy.

community Why Fin/Dut Isn't Working for You GPR133: a new hairloss mechanism + Steroid Hair Loss Deep Dive

6 upvotes 1 month ago

Hair loss may be linked to the GPR133 receptor, independent of the androgen receptor pathway. Treatments like finasteride, dutasteride, minoxidil, RU58841, and KX-826 show varying results, with hair loss persisting due to high testosterone and GPR133's role.

community We should actually be hopeful for these recent new developments

112 upvotes 1 year ago

AI advancements, like AlphaFold, are speeding up drug discovery for hair loss, promising more effective treatments. Current options like minoxidil and finasteride have limitations, but new developments could improve solutions in 5-10 years.

community Hair Shaft Diameter and Density Comparison

13 upvotes 4 weeks ago

The conversation discusses differences in hair shaft diameter and density between thinning and denser areas on the scalp. Treatments mentioned include Minoxidil, finasteride, and dutasteride.

community FDA Policy Shift Explained: What It Actually Means for PP405, VDPHL-01, Breezula and Hair Loss Drug Timelines

in Research/Science 42 upvotes 6 months ago

The FDA policy change may speed up approval for hair loss drugs like PP405, VDPHL-01, and Breezula by potentially eliminating the need for a second confirmatory Phase 3 trial. Approval timelines could be as early as 2028 for some treatments if Phase 3 results are strong.

community Recent trials investigating mesenchymal stem cell derived exosomes demonstrate significant increases in anagen duration and hair shaft caliber by upregulating Wnt/beta-catenin pathways.

4 upvotes 3 weeks ago

Exosomes from mesenchymal stem cells can increase hair growth by enhancing anagen duration and hair shaft thickness through the Wnt/beta-catenin pathway. Phase 2 trials show improved hair counts over 24 weeks.

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

learn Cetirizine

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.
