research Studies on the Preservative Condition and the Ultrastructure of Hair of Newly Found Sixteenth Century Mummy in Paju

6 citations , January 2005 in “Han-guk hyeonmigyeong hakoeji/Applied microscopy”

This study found that the 16th-century mummified hair from a female mummy in Paju was remarkably well-preserved, with the hair's ultrastructural features maintained likely due to a calcium-rich surface coat.

research Ruth M. Kempson, Presupposition and the delimitation of semantics (Cambridge Studies in Linguistics, 15). Cambridge: Cambridge University Press, 1975. Pp. xi + 235; - Deirdre Wilson, Presuppositions and non-truth-conditional semantics. London: Academic Press, 1975. Pp. xiii + 161.

September 1976 in “Journal of Linguistics”

This review contrasts two books on presupposition in linguistics: Kempson's "Presupposition and the delimitation of semantics" and Wilson's "Presuppositions and non-truth-conditional semantics," without reporting new findings.

community Do you believe these studies are real or just fear mongering

in Finasteride/Dutasteride 157 upvotes 11 months ago

Finasteride can regrow hair but may cause depression and suicidal thoughts in some users. The connection between finasteride and mental health issues is debated, with some attributing it to pre-existing conditions or stress.

community Who won’t respond to minoxidil? (Studies)

33 upvotes 6 months ago

Minoxidil's effectiveness varies due to differences in sulfotransferase enzyme levels in the scalp, affecting people with conditions like ASD, liver disease, and androgenic alopecia. Treatments like topical tretinoin, microneedling, and using minoxidil sulfate instead of regular minoxidil can improve results for those with low enzyme levels.

community Can gains from stemoxydine be permanently kept with 5AR inhibitors?

in Research/Science 1 year ago

Stemoxydine's effects on hair growth are uncertain and not well-studied, with users reporting mixed results and concerns about maintaining gains. Some users combine it with 5AR inhibitors like Dutasteride, but results vary, and conditions like lichen planopilaris complicate treatment.

community Don't use PP405 from everychem. it is likely fake.

63 upvotes 1 year ago

PP405 from Everychem is likely fake and potentially harmful, with concerns about its stability and the risk of using the wrong MPC inhibitor, which could damage hair follicles. The real PP405 was studied under strict conditions, and DIY attempts are discouraged due to unknown formulation and quality control.

community Hair repigmentation of poliosis circumscripta in androgenetic alopecia patient treated with exosomes and fractional picosecond laser

2 upvotes 2 years ago

Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.

learn Tofacitinib

a JAK inhibitor for alopecia areata and other autoimmune conditions

What types of hair loss conditions are most commonly associated with tofacitinib use in clinical settings? Published studies link tofacitinib mainly to alopecia areata and its severe variants — as an off-label drug being studied for them, not as a cause of hair loss. The evidence is mostly small, open-label or retrospective, and relapse after stopping is commonly reported.
What are the key limitations and considerations surrounding tofacitinib in hair loss products and therapies? Reported hair regrowth with tofacitinib comes from alopecia areata, an autoimmune condition — mostly from small, non-randomized studies, with relapse common after stopping. There is no good evidence it helps pattern hair loss, and it is not approved for hair loss anywhere.

learn Sulforaphane

How often should sulforaphane-based products be used for hair loss prevention? No human trial has tested sulforaphane for hair loss prevention, so there is no established usage frequency. Oral supplements are taken daily in research on unrelated conditions and the hair-specific evidence is limited to cell, mouse and isolated-follicle studies, so any schedule is extrapolation rather than a dosing guideline.

learn RU58841

a potent but unapproved and potentially problematic topical anti-androgen

learn Spironolactone

powerful topical and oral anti-androgen used mostly by women

learn Tretinoin

the gold standard retinoid in dermatology that's also helpful for hair regrowth alongside Minoxidil

learn Vitamin D

vitamin you should probably be taking for general health might also help your hair a little

learn Hair Transplant

What conditions can a hair transplant treat? Clinics say transplants can treat pattern baldness, long-inactive scarring alopecia and thinning; a transplant only moves hair a person still has, so the cause of the loss has to be diagnosed first.
Can I get a hair transplant if I have a medical condition? You may be eligible for a hair transplant, but consult a specialist first.
