Did you mean Telogen Phase?

Glossary Telogen Phase

hair follicles are inactive, and hair naturally falls out

The Telogen Phase, also known as the Resting Phase or hair shedding phase, is the final stage of the hair growth cycle. During this phase, hair follicles are inactive, and the hair strand is fully formed but not actively growing. This phase typically lasts around 2-4 months, after which the hair naturally falls out, making way for new hair growth in the subsequent Anagen Phase.

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.

research Identification of Telogen Markers Underscores that Telogen Is Far from a Quiescent Hair Cycle Phase

21 citations , November 2011 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

community Tretinoin for some men(not all) can cause non-telogen effluvium hair loss

in Research/Science 5 upvotes 1 year ago

Tretinoin can cause non-telogen hair loss in some men by inducing catagen-like changes in hair follicles and through retinoid toxicity, especially when used with minoxidil. Some users report hair loss even when using retinoids on the face, while others experience benefits when combined with treatments like finasteride and minoxidil.

community Telogen Effluvium

4 upvotes 8 years ago

Hair regrowth after telogen effluvium, with the user experiencing hair loss at the temples and regrowth after taking omega-3/fish oil tablets. Suggestions include consulting a dermatologist and considering supplements like Biotin, Zinc, and Vitamin D.

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 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 Why don't Minoxidil regenerated hairs become terminal on the head?

in Minoxidil 101 upvotes 1 year ago

Minoxidil helps hair growth by increasing blood flow and prolonging the growth phase, but it doesn't address the root cause of hair loss, such as DHT sensitivity. Finasteride can help maintain some gains by blocking DHT, but stopping Minoxidil often leads to hair loss because the new hairs are dependent on it.
