Did you mean Anagen Hair Follicles?

Glossary Anagen Hair Follicles

phase where hair actively grows

Anagen hair follicles, also known as growing hair follicles or active hair follicles, are in the phase of the hair growth cycle where the hair is actively growing. This phase can last anywhere from 2 to 7 years, during which the hair shaft is continuously produced by the follicle, resulting in longer hair. This is the most prolonged phase of the hair cycle and is crucial for determining the length of the hair.

research Effect of Plantago asiatica L. extract on the anagen phase in human hair follicle dermal papilla cells

5 citations , March 2023 in “Journal of Cosmetic Dermatology”

This study reports that Plantago asiatica L. extract may promote hair growth by enhancing growth factor production and activating specific signaling pathways in hair follicle dermal papilla cells.

research Morus alba Root Extract Induces the Anagen Phase in the Human Hair Follicle Dermal Papilla Cells

28 citations , July 2021 in “Pharmaceutics”

This study found that Morus alba root extract activates β-catenin in hair follicle dermal papilla cells, promoting the transition to the anagen phase and enhancing hair growth factor secretion.

research Exposure to gamma-rays at the telogen phase of the hair cycle inhibits hair follicle regeneration at the anagen phase in mice

6 citations , November 2013 in “International Journal of Radiation Biology”

In this study, γ-ray irradiation of mice reduced hair follicle density and pigmentation, suggesting damage to stem cells and progenitors for keratinocytes and melanocytes.

research Exposure to gamma-rays at the telogen phase of the hair cycle inhibits hair follicle regeneration at the anagen phase in mice

November 2013 in “Institutional Repositories DataBase (IRDB)”

In this study, γ-ray exposure in mice decreased hair follicle density and pigmentation, suggesting damage to stem cells affecting hair follicle regeneration.

research Exposure to gamma-rays at the telogen phase of the hair cycle inhibits hair follicle regeneration at the anagen phase in mice

November 2013 in “Institutional Repositories DataBase (IRDB)”

In this study, γ-ray irradiation in mice during the first telogen phase led to decreased hair follicle density and pigmentation anomalies, suggesting damage to stem cells and progenitors for keratinocytes and melanocytes.

community PP405: The Ultimate Hair Loss Drug for Complete Hair Growth

211 upvotes 1 year ago

PP405 is a new hair loss treatment in phase 2 trials that may promote hair growth by increasing lactate production and activating hair follicle stem cells. It could potentially replace hormone-disrupting treatments like Minoxidil and finasteride.

community TDM-105795 phase 2 results are in!

27 upvotes 2 years ago

TDM-105795 showed promising hair growth results, with higher efficacy than placebo and minimal side effects. It activates dormant hair follicle stem cells and may maintain gains without immediate loss, unlike minoxidil.

community Can single hairs follicules be able to produce two hairs once again with treatment? Never saw a study about that.

in Finasteride/Dutasteride 11 upvotes 2 years ago

The conversation is about whether treatments like finasteride, dutasteride, and minoxidil can make single hair follicles produce multiple hairs again. The user is curious if these medications can thicken hair and prolong the growth phase.

community Forgotten Hair Loss Peptide by L'Oreal: KPV

5 upvotes 2 years ago

KPV, a peptide patented by L'Oreal, may promote hair growth and reduce hair loss by extending the anagen phase and has anti-inflammatory properties. It could be combined with treatments like minoxidil for enhanced effects.

community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

67 upvotes 11 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.

learn Latanoprost

glaucoma medication with hair follicle stimulant effects

How does latanoprost work to make eyelashes and possibly scalp hair grow? Studies report that latanoprost, a prostaglandin analog, lengthens the anagen (growth) phase of hair follicles, which is the mechanism given for the eyelash thickening seen in glaucoma patients; on the scalp the evidence is one 16-man pilot study and animal work, so the effect there is unproven.

learn Stemoxydine

chemical from L'Oreal that encourages hair to enter growth phase

learn Exosomes

Microscopic delivery system that sends growth-promoting signals to hair follicles

learn Osteopontin

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Dexpanthenol

precursor of vitamin B5 with hair stimulating effects

learn Adenosine

Adenosine: How natural is this ingredient and how does it act on the scalp? Adenosine is a naturally occurring compound that promotes hair growth by extending the anagen phase.

learn KY19382

How does KY19382 actually stimulate dormant hair follicles to grow again? KY19382 stimulates dormant hair follicles by reactivating the Wnt/β-catenin signaling pathway.

learn Folic acid

How does folic acid support hair follicle health and growth at a cellular level? Folate is required for the DNA synthesis that fast-dividing hair matrix cells depend on, and severe deficiency causes anemia—but no published trial has given folic acid to people with hair loss and measured the result, so a growth effect is a mechanism, not a finding.
