research Melanocytes from the Outer Root Sheath of Hair Follicles Cultivated on Collagen Membrane Improve their Melanotic Properties

5 citations , January 2012 in “Journal of Tissue Science & Engineering”

In this study, collagen I decellularized scaffolds enhanced the growth and melanotic properties of hair follicle melanocytes, suggesting their potential as effective carriers for transplantation in vitiligo treatment.

research Effect of Minoxidil Sulfate on the Growth of Human Anagen Hair Follicles Grown in Collagen Gels, and on the Colony Growth of Human Cultured Outer Root Sheath Cells in vitro.

1 citations , January 1992 in “The Nishinihon Journal of Dermatology”

This study found that minoxidil sulfate did not enhance hair follicle growth or cell proliferation in isolated human hair follicles at concentrations of 0.1, 1, and 10 μg/ml.

research Pulling force deforms hair follicle root sheath nuclei and surrounding dermal collagen matrix differently at infundibulum, isthmus and suprabulbar regions

2 citations , April 2019 in “Experimental Dermatology”

This study observed that applying a pulling force to hair follicles led to significant compression of nuclei in certain cell layers and distinct collagen changes at different follicle depths.

research Single-Cell RNA Profiling of Human Skin Reveals Age-Related Loss of Dermal Sheath Cells and Their Contribution to a Juvenile Phenotype

37 citations , January 2022 in “Frontiers in Genetics”

This study found that dermal sheath stem cell characteristics are lost with aging in humans, affecting skin rejuvenation and structure, and identified specific proteins like Activin A influencing keratinocyte and fibroblast activity.

research Enhanced in vitro hair growth at the air-liquid interface: minoxidil preserves the root sheath in cultured whisker follicles

12 citations , July 1993 in “In Vitro Cellular & Developmental Biology - Animal”

Minoxidil enhances hair growth and preserves the root sheath in cultured follicles.

community Perifollicular Fibrosis and its role in androgenetic alopecia. Is Aminexil/Kopexil a must for anyone with AGA?

5 upvotes 4 years ago

Aminexil/Kopexil may help reduce hair loss by addressing perifollicular fibrosis in androgenetic alopecia, but it lacks the extensive clinical backing of finasteride and minoxidil. Some users find it effective, but availability and cost are issues, especially in the US where it's not FDA-approved.

community Hair loss research focused on chemistry for decades because we misunderstood the mechanics of growth.

51 upvotes 7 months ago

Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.

community Federal Grant Cuts have impacted PP405 related research

459 upvotes 1 year ago

Federal funding cuts have delayed PP405 research, affecting hair loss treatment progress, though clinical trials will continue. The discussion highlights PP405's potential compared to minoxidil and finasteride and stresses the importance of government-funded research.

community Last Post Before I Switch Back to Finasteride From Dutasteride

in Finasteride/Dutasteride 29 upvotes 1 year ago

The user plans to switch from dutasteride back to finasteride due to worsening hair loss, possibly due to increased scalp testosterone. Others report mixed results with both treatments, showing individual variability.

community A Theory on Why Microneedling Works

175 upvotes 6 years ago

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.
