Glossary Fibroblast Growth Factor 5

protein that inhibits hair growth by signaling phase transition

Fibroblast Growth Factor 5 (FGF5) is a protein that plays a crucial role in regulating the hair growth cycle. Specifically, it acts to inhibit hair growth by signaling the transition from the growth phase (anagen) to the regression phase (catagen), which can lead to shorter hair growth periods and potentially contribute to conditions like alopecia.

research Fibroblast growth factor 5-short (FGF5s) inhibits the activity of FGF5 in primary and secondary hair follicle dermal papilla cells of cashmere goats

42 citations , September 2015 in “Gene”

This study demonstrated that FGF5s acts as an inhibitor of FGF5 in regulating hair growth cycles in cashmere goat dermal papilla cells.

research CRISPR/Cas9-mediated Disruption of Fibroblast Growth Factor 5 in Rabbits Results in a Systemic Long Hair Phenotype by Prolonging Anagen

13 citations , March 2020 in “Genes”

This study found that FGF5-/- rabbits exhibited a significant long hair phenotype by prolonging the anagen phase, suggesting FGF5 acts as a negative regulator of hair growth.

research A homozygous missense mutation in the fibroblast growth factor 5 gene is associated with the long-hair trait in Angora rabbits

5 citations , June 2023 in “BMC genomics”

This study found that a specific genetic mutation in the Fgf5 gene may contribute to the long-hair trait in Angora rabbits by reducing the binding capacity of the FGF5 protein.

research Effect of cysteine‐free human fibroblast growth factor‐5s mutant ( FGF5sC93S ) on hair growth

5 citations , November 2020 in “Dermatologic Therapy”

This study found that a mutant form of the FGF5s protein, FGF5sC93S, significantly increased hair count after 24 weeks of application on human scalps, suggesting its potential as a hair growth treatment.

community REVOLUTION in AUGUST: New possibilities according to Dr. Muñoz (pinacidil, cromakalim, diazoxide and nicorandil)

13 upvotes 1 year ago

Dr. Muñoz's discovery suggests that targeting potassium channels in fibroblasts could reactivate hair growth, offering new treatment possibilities for alopecia. Potential strategies include using minoxidil, diazoxide, and other potassium channel openers, as well as bioelectric devices and direct growth factor applications.

community Serum based on plant extracts boosts hair growth in weeks.

44 upvotes 11 months ago

A serum containing Centella asiatica extracellular vesicles, IGF-1, FGF-7, and caffeine significantly improved hair thickness, density, length, and reduced hair loss after 56 days. The conversation also discusses how treatments like finasteride, minoxidil, and ketoconazole address different aspects of hair loss by reducing DHT, improving blood flow, and lowering inflammation.

community Day 155 of 5mg oral minoxidil + 0,5mg oral dutasteride daily

in Progress Pictures 103 upvotes 6 months ago

A user shared progress on hair regrowth using 5mg oral minoxidil and 0.5mg oral dutasteride daily, noting small hair growth and no significant side effects except bushier eyebrows. The conversation includes encouragement, personal experiences with hair loss treatments, and discussions on the effectiveness of microneedling.

community DHT Isn’t the Only Factor in Hair Loss and That Might Be the Key to a Real Cure

373 upvotes 6 months ago

Hair loss involves more than just DHT, with genetic factors like TRPS affecting hair follicles. Treatments such as Amplifica's AMP-601 and AMP-303 target stem cells for potential hair growth solutions.

community Comprehensive Microneedling Guide

292 upvotes 4 years ago

Microneedling for hair restoration involves daily use of a 0.3 mm device and weekly use of a 0.5 mm device. Combining microneedling with Minoxidil can enhance hair growth.

What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
