research Identification of genes and proteins associated with anagen wool growth

10 citations , September 2016 in “Animal genetics”

In this study, researchers identified a number of differentially expressed genes that may influence wool growth in Aohan fine wool sheep, offering insight into the genetic regulation of wool quality and yield.

research The mouse hairy ears mutation exhibits an extended growth (anagen) phase in hair follicles and altered Hoxc gene expression in the ears

10 citations , November 2008 in “Veterinary Dermatology”

In this study, the misshaped and hairy ear phenotype in mutant mice was linked to mis-expression of certain Hoxc genes due to a chromosomal inversion.

research The clock gene brain and muscle Arnt-like protein-1 (BMAL1) is involved in hair growth

9 citations , August 2013 in “Archives of Dermatological Research”

This study concluded that the expression of clock genes, specifically BMAL1, in hair follicles is linked to circadian rhythm, and BMAL1 regulates hair growth.

research Characterisation and functional analysis of the WIF1 gene and its role in hair follicle growth and development of the Angora rabbit

2 citations , September 2022 in “World Rabbit Science”

This study found that the WIF1 gene may play a crucial role in hair follicle growth and development in Angora rabbits by regulating specific genes and proteins.

research Genes Expression Profiling for Hair Growth by Finasteride and Luteolin Administration in Murine Model

January 2013

This study found that finasteride and luteolin may prevent hair loss and promote hair growth in vitro and in vivo by modulating specific gene expressions related to cell differentiation and apoptosis.

community Odd Hair Growth (Possibly More Than Genetics?)

in Is this regrowth? 2 upvotes 2 years ago

A 23-year-old user shares their hair regrowth journey, questioning if genetics or other factors are at play. They use Rogaine, finasteride, vitamin B12, biotin, Thera M Plus, and derma stamping, and seek advice on their regimen and hair growth patterns.

community Bloodflow? Does it affect hair growth?

23 upvotes 7 years ago

Hair loss is primarily caused by genetic sensitivity to DHT, not lifestyle factors like diet or exercise. Treatments like Minoxidil and Finasteride can help, but it's important to consult a dermatologist to determine the best approach for individual cases.

community Intermittent fasting reduces hair growth?!? :(

35 upvotes 1 year ago

Intermittent fasting may inhibit hair growth by triggering a stress response that affects hair-follicle stem cells. Some users believe genetics and DHT play a larger role in hair loss, and treatments like Minoxidil and Finasteride are mentioned as ineffective for some.

community Seeking Suggestions for VEGF Gene Therapy in Hair Transplants

in Research 112 upvotes 5 months ago

A user is exploring VEGF gene therapy to enhance hair transplant results, considering measuring hair shaft diameter and growth rate. Suggestions include using phototrichograms and possibly adding PRP, though its effectiveness is uncertain.

community Pilose antler extracts promotes hair growth in androgenetic alopecia mice by activating hair follicle stem cells via the AKT and Wnt pathways

11 upvotes 2 years ago

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

learn Scalp Micropigmentation

Will scalp micropigmentation damage my existing hair or follicles? Providers say SMP sits above the hair follicles and does not harm them. No study has tested this, and infection or scarring from any tattoo can affect the skin.

learn Vascular Endothelial Growth Factor

Are there risks or side effects associated with treatments that increase Vascular Endothelial Growth Factor (VEGF)? In a VEGF gene-therapy trial for leg artery disease, raising VEGF caused more leg swelling, and excess VEGF drives leaky, abnormal vessels in mice and in eye disease. No long-term studies have tested the safety of treatments that raise VEGF in the scalp.

learn Follistatin

Protein that blocks activin, a growth-regulating signal

learn Lavender

Plant essential oil used in scalp products

Does lavender promote hair growth or just soothe an irritated scalp? A 2016 study found more hair growth in mice treated with lavender oil, but no trial has tested lavender alone for hair loss in people. Lavender oil can cause skin allergy, and case reports link lavender products to breast growth in children.

learn Procyanidin

Plant polyphenol found in apples and grape seeds

learn Tretinoin

Vitamin A retinoid cream, prescribed for acne

learn GHK-Cu

Copper peptide used in skin and hair cosmetics

learn Caffeine

Does caffeine stimulate hair growth or only slow hair loss? Caffeine stimulates hair follicles in laboratory cultures, and one open-label, manufacturer-funded trial in 210 men found a 0.2% caffeine topical non-inferior to minoxidil 5% on an anagen-ratio endpoint. A 2025 systematic review found only a few small controlled trials, mostly rated low or very low quality, and none in alopecia areata.

learn Bimatoprost

Can a lash-growth serum like bimatoprost actually work for your scalp? Bimatoprost (Latisse) is FDA-approved only for eyelashes, not the scalp. In the larger of two Allergan phase 2 scalp trials, every bimatoprost formulation gave smaller hair-count gains than minoxidil 5%; the results were posted to ClinicalTrials.gov but never published in a journal, and scalp use remains off-label and experimental.
