research Polarized microscopy in genetic hair disorders: case series
This study utilized polarized light microscopy to examine hair shafts in ten children with rare genetic disorders, such as Netherton syndrome and ectodermal dysplasia, providing valuable diagnostic insights into hair thickness, composition, and structural irregularities associated with these conditions.
research Comparative study of male and female human hair: A microscopic analysis.
This study found that male and female hair specimens show structural differences, with female hair having a brown color at the distal end and smooth surface texture, while male hair is completely black and shows surface irregularities; these differences may aid forensic analysis.
research Structural abnormalities of the hair shaft
This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.
research Pathogenesis in pili torti: morphological study
This study found that the twisted hair shafts characteristic of pili torti may result from uneven outer root sheath cell development, leading to irregular hair shaft modeling and twisting.

A user shared impressive hair regrowth results after three months of taking 1mg daily of finasteride. Other users commented on their experiences and the effectiveness of different treatments like minoxidil and dutasteride.
community Hair Shaft Diameter and Density Comparison
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
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.
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.
community Mesotherapy Dutasteride Reverses Female AGA; repairs hair shaft integrity as well
Mesotherapy with dutasteride significantly improves hair density, thickness, and quality in female pattern hair loss with minimal side effects. The treatment strengthens hair cuticles by reducing DHT through 5AR inhibition.

6 / 801 results- 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.
