Glossary Terminal Hair Follicles

structures producing thick, pigmented hair on scalp and body

Terminal hair follicles are the structures in the skin that produce terminal hair, which is the thick, pigmented hair found on the scalp, face, armpits, and pubic area. Unlike vellus hair, which is fine and light, terminal hair is coarser and darker, and its growth is influenced by hormonal changes, particularly androgens.

Pattern Hair Loss: Assessment of Microinflammation in Miniaturized and Terminal Hair Follicles Through Horizontal Histologic Sections

research Pattern hair loss: Assessment of microinflammation in miniaturized and terminal hair follicles through horizontal histologic sections

11 citations , April 2020 in “Journal of The American Academy of Dermatology”

This commentary reviews the evidence for microinflammation's role in pattern hair loss and suggests that further studies with age- and sex-matched controls are needed to substantiate the findings.

Expression of the L-Fucose Moiety on Infrainfundibular Follicular Keratinocytes of Terminal Follicles, Its Decreased Expression on Vellus and Indeterminate Follicles of Androgenetic Alopecia, and Re-Expression in Drug-Induced Hair Regrowth

research Expression of the L-Fucose Moiety on Infrainfundibular Follicular Keratinocytes of Terminal Follicles, Its Decreased Expression on Vellus and Indeterminate Follicles of Androgenetic Alopecia, and Re-Expression in Drug-Induced Hair Regrowth

9 citations , January 1992 in “Journal of Investigative Dermatology”

This study found distinct differences in UEA I glycoprotein binding on follicular keratinocytes between anagen and telogen hair follicles, with staining associated with follicle length and regrowth.

research 561 Vellus-to-terminal hair follicle reconversion does occur in male pattern balding in a new humanized mouse model of androgenetic alopecia and is promoted by minoxidil and PRP

November 2022 in “Journal of Investigative Dermatology”

This study suggests that vellus to terminal hair follicle reconversion can occur in male pattern androgenetic alopecia using an in vivo model with minoxidil and platelet-rich plasma treatment.

Viable Terminal Scalp Hair Follicles Are Necessary and Sufficient for Clinical Efficacy of Finasteride in Male Pattern Hair Loss

research Viable terminal scalp hair follicles constitute a necessary and sufficient biological end‐organ that conditions clinical efficacy of finasteride in males with male pattern hair loss without implying reversal of miniaturized follicles

6 citations , June 2019 in “Skin Research and Technology”

In this study, finasteride treatment for two years did not significantly reverse miniaturized hair follicles in men with male pattern hair loss, challenging the "reversal hypothesis" as 79 out of 113 miniaturized hairs remained unchanged.

Characterization of Cell Cycle Arrest and Terminal Differentiation in a Maximally Proliferative Human Epithelial Tissue: Lessons from the Human Hair Follicle Matrix

research Characterisation of cell cycle arrest and terminal differentiation in a maximally proliferative human epithelial tissue: Lessons from the human hair follicle matrix

30 citations , April 2017 in “European Journal of Cell Biology”

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

community Minoxidil experiment on single hair follicle

1689 upvotes 1 year ago

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

community Confused why people are calling PP405 a cure...it never claimed to be able to undo miniaturization or revert vellus back to terminal hairs. It seems to be more of a growth stimulant like minoxidil.

in Research/Science 55 upvotes 1 year ago

PP405 is not a cure for hair loss but may reactivate dormant hair follicles, similar to minoxidil. It is unlikely to help with miniaturized or vellus hairs and is still in trial phases, with availability expected around 2030.

community How likely is it to reverse the hair count for each hair follicle?

in Chat 12 upvotes 2 years ago

Hair follicles can potentially produce more hair strands with treatments like Minoxidil and finasteride. Notable improvements in hair density are possible, but achieving multiple strands per follicle is uncertain.

community "Unlimited" hair follicles for HT?

31 upvotes 4 years ago

Hair loss discussion mentions Verterporfin for scar-free healing and hair follicle regeneration. Human study expected within 2 years.

community Found a slide summary for PP405

35 upvotes 5 months ago

PP405 shows promise in stimulating new terminal hair growth by activating dormant follicles, with no systemic adverse effects observed in a short-term trial. However, long-term efficacy remains unproven, and further trials are needed to confirm its potential as a hair loss treatment.

How long does it take for clascoterone to show results on hair growth? Clascoterone is not approved for hair loss; it is investigational. In the trials reported so far, application was twice daily and increases in terminal hair count were reported at around 6 months, with more sustained change reported between 6 and 12 months.
