Did you mean Hair Follicle Size?

Glossary Hair Follicle Size

diameter of the small cavity in the skin producing hair

Hair follicle size refers to the diameter of the hair follicle, which is the small, tubular cavity in the skin from which hair grows. This size can influence the thickness and texture of the hair strand produced; larger follicles typically produce thicker hair, while smaller follicles produce finer hair. Understanding hair follicle size is important in fields like dermatology and trichology for diagnosing and treating hair-related conditions, such as alopecia.

research Control of hair growth and follicle size by VEGF-mediated angiogenesis

520 citations , February 2001 in “Journal of Clinical Investigation”

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

research Differences in Hair Follicle Dermal Papilla Volume are Due to Extracellular Matrix Volume and Cell Number: Implications for the Control of Hair Follicle Size and Androgen Responses

231 citations , December 1999 in “Journal of Investigative Dermatology”

This study found that the volume of a hair follicle's dermal papilla is strongly correlated with its size, primarily due to the number of cells it contains and the volume of extracellular matrix.

Scalable Production of Controllable Dermal Papilla Spheroids on PVA Surfaces and the Effects of Spheroid Size on Hair Follicle Regeneration

research Scalable production of controllable dermal papilla spheroids on PVA surfaces and the effects of spheroid size on hair follicle regeneration

78 citations , October 2012 in “Biomaterials”

This study found that both human and rat dermal papilla spheroids can induce hair follicle neogenesis, but larger spheroids increase inductivity without significantly affecting hair fiber diameter.

research Size-dependent penetration of nanoemulsions into epidermis and hair follicles: implications for transdermal delivery and immunization

96 citations , April 2017 in “Oncotarget”

This study found that nanoemulsions of different sizes vary in their ability to penetrate skin layers, with smaller sizes aiding transdermal delivery and potential applications in transcutaneous immunization.

research Variations of Hair Follicle Size and Distribution in Different Body Sites

405 citations , January 2004 in “Journal of Investigative Dermatology”

This study found that hair follicle characteristics vary significantly across different body sites, with the forehead and calf showing the highest potential follicular reservoirs, challenging previous assumptions about skin appendage distribution.

community Surprisingly thorough study on He-Shou-Wu/Fo Ti

13 upvotes 3 years ago

He Shou Wu (Fo Ti) extract was found to prolong the hair growth phase, inhibit 5-alpha-reductase (like finasteride), reduce androgen receptors, and increase growth factors, potentially outperforming minoxidil in recovering hair follicle size after DHT exposure. Two compounds, emodin and TSG, are identified as responsible for these effects and warrant further investigation.

community PP405 Won’t Work: Follicle Is Miniaturized, Fibrosed, And Missing Key Support Cells

7 months ago

PP405 is ineffective for miniaturized, fibrosed hair follicles in androgenetic alopecia. AMP303 may activate hair follicle stem cells, but minoxidil and finasteride are still the main treatments.

community Why not move miniaturized hair follicles somewhere else to treat them? Alternative to hair cloning?

4 upvotes 1 year ago

Exploring the idea of transplanting miniaturized hair follicles to healthier areas to potentially reverse hair loss, with concerns about DHT sensitivity and scar tissue formation. The conversation also humorously considers using mice for hair growth experiments.

community Microneedling and miniaturized hair follicles depth

in Microneedling 8 upvotes 1 year ago

Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.

community If PP405 does revive "dead" hair follicles would DHT blockers theoretically be enough to maintain that new hair

in Research/Science 115 upvotes 11 months ago

PP405 may revive dormant hair follicles, and DHT blockers like finasteride or dutasteride could maintain new hair. Combining PP405 with minoxidil might be optimal, but long-term effects and continuous use are uncertain.
