research Aberrant Wnt signalling induces comedo-like changes in the upper hair follicle

1 citations , October 2020 in “Research Square (Research Square)”

This study found that abnormal Wnt signalling in stem cells may contribute to blackhead formation in acne by inhibiting cell differentiation and causing cell accumulation in the junctional zone.

research TERT/BMI1-transgenic human dermal papilla cells enhance murine hair follicle formation in vivo

1 citations , March 2022 in “Journal of Dermatological Science”

This study concluded that overexpressing TERT and BMI1 in cultured human dermal papilla cells extended their lifespan and enhanced their ability to induce hair growth in mice.

research 'Atrophic telogen effluvium' from cytotoxic drugs and a randomized controlled trial to investigate the possible protective effect of pretreatment with a topical vitamin D3 analogue in humans

47 citations , July 2005 in “British Journal of Dermatology”

This study found no protective effect of topical calcipotriol on hair loss in chemotherapy patients, and the authors propose the term "atrophic telogen effluvium" for this type of hair loss.

research Alterations in epidermal stem cells within the pilosebaceous unit in atrophic acne scars

February 2024 in “Australasian journal of dermatology”

This study found that in atrophic acne scars, inflammation infiltrates the pilosebaceous unit over time, affecting resident stem cells and hindering the normal regeneration of the epidermis and adnexal structures, leading to scarring.

research Updated Management of Atrophic Post Acne Scars: Review Article

October 2021 in “The Egyptian Journal of Hospital Medicine ”

This study concluded that combination therapies often yield better results for treating atrophic post-acne scars than single treatments.

community Anyone here have a lot of knowledge on hair follicle stem cells and progenitor cells for PP405?

in Chat 4 upvotes 8 months ago

Hair follicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.

community Microneedling must reach the stem cells in the upper hair shaft

82 upvotes 4 years ago

Microneedling should target depths of 0.5mm to 1.5mm for hair loss, with weekly sessions at 1mm recommended. Combining microneedling with Minoxidil is common for improved results.

community Pyrilutamide (KX-826) personal consideration

in Research/Science 1 upvotes 1 year ago

Pyrilutamide (KX-826) is discussed as an anti-androgen treatment for hair loss, with mixed user experiences. Some users report no results, while others find it mildly effective.

community Long term finasteride users; Did you notice any improvement after 2 years?

in Finasteride/Dutasteride 14 upvotes 3 years ago

Long term Finasteride users and whether or not they have noticed improvements after two years of use, with other treatments such as Minoxidil and dermarolling also discussed. Some replies suggest that improvement is possible even beyond the two year mark while others caution against believing studies backed by the Post-Finasteride Foundation.

community Do hair follicles dies or are dormant ?

in Finasteride/Dutasteride 92 upvotes 1 year ago

Hair follicles can be dormant and potentially revived with treatments like finasteride and minoxidil, but irreversible loss occurs if certain structures are destroyed. Early intervention is more effective, and additional methods like microneedling may help.

learn Alopecia Areata

autoimmune disorder causing patchy hair loss

learn PP405

Got small bald patches they say are from stress? PP405 sprays could help bring them back to life. PP405 is an experimental topical gel from Pelage Pharmaceuticals that inhibits the mitochondrial pyruvate carrier; its registered Phase 2 trial (NCT06393452) tested it once daily in 78 adults with pattern hair loss, for safety and tolerability. It is not approved, not for sale, and has not been studied in alopecia areata or stress-related shedding.

learn Hair Transplant

Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.

learn GHK-Cu

Heard alopecia areata leaves scar-like spots? Some peptides are helping those areas regrow hair. Alopecia areata patches usually still have living follicles. Peptides are being studied as a possible add-on, but the evidence is small and early. See a dermatologist for treatment.

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.

learn Follistatin

glycoprotein that inhibits TGF-β and promotes hair growth by antagonizing activin

learn Salicylic acid

What makes alopecia areata different from other types of hair loss, and can topical Salicylic acid treatments help regrow the affected areas? Alopecia areata is an autoimmune condition, and salicylic acid does not promote hair regrowth.

learn TDM-105795

What types of alopecia or hair loss conditions might TDM-105795 be designed to target based on current research? TDM-105795 may target non-scarring alopecia, particularly androgenetic alopecia.
