research Validity of methyl mercury hair analysis: mercury monitoring in human scalp/nude mouse model

33 citations , November 2007 in “JAT. Journal of applied toxicology/Journal of applied toxicology”

In this study, human scalp hair grafted onto nude mice accurately reflected methyl mercury exposure, demonstrating its potential as a research model for monitoring mercury incorporation into human hair.

Tyrosine Kinase 2 Inhibition Ameliorates the Phenotype of Lesional Alopecia Areata Scalp Skin Ex Vivo, and Reverses the Induction of Human Alopecia Areata in a Humanized Mouse Model

research 014 Tyrosine Kinase 2 Inhibition Ameliorates the Phenotype of Lesional Alopecia Areata Scalp Skin Ex Vivo, and Reverses the Induction of Human Alopecia Areata in a Humanized Mouse Model

November 2022 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study observes that TYK2 inhibition with BMS-986202 may extend hair follicle growth phases and decrease inflammatory cell markers in alopecia areata, suggesting potential for clinical application.

research 001 Human scalp hair follicles are protected from alopecia areata in vivo by regulatory γδT cells

November 2024 in “Journal of Investigative Dermatology”

γδT cells can protect hair follicles from alopecia areata and promote hair regrowth.

research 3D Modelling for Solar Erythemal UV Protection Provided by Human Hair

1 citations , November 2019 in “Applied sciences”

This study used a 3D simulation to show that human hair provides varying levels of UV protection depending on head orientation and hair alignment, highlighting hair's role in scalp UV protection, especially for those with alopecia.

research An in Vitro Model for the Study of Human Hair Growth

13 citations , December 1991 in “Annals of the New York Academy of Sciences”

This study observed that human anagen hair follicles can grow in vitro when maintained serum-free, with possible implications for understanding hair follicle growth mechanisms.

community 2-deoxy-D-ribose (2dDR), a sugar molecule, was found to be 80%-90% as effective as minoxidil in promoting hair growth and neovascularization in androgenic alopecia models, showing promise for alopecia treatment.

in Research/Science 18 upvotes 2 years ago

2-deoxy-D-ribose, a sugar molecule, is found to be 80%-90% as effective as Minoxidil in promoting hair growth, showing potential for alopecia treatment. Concerns include high cost, lack of human studies, and possible side effects like diarrhea and nausea.

community Could coffee contribute to hair loss?

4 upvotes 4 years ago

Coffee may negatively impact hair health due to its vasoconstrictor effects, potential to increase DHT, and interference with nutrient absorption. There is no strong clinical evidence linking caffeine to hair loss or regrowth in humans, but moderation is advised.

community Fin for 7 months and my sclap is now transparent

in Progress Pictures 16 upvotes 6 months ago

A 24-year-old male has been using finasteride for 7 months and noticed thinning hair, especially when wet, and is concerned about the effectiveness of the treatment. Suggestions include continuing finasteride, considering minoxidil, and possibly trying micro-needling.

community Scalp inflammation cleared after stopping "spoiled" milk - what about follicles,shedding?

4 upvotes 6 months ago

Switching milk brands cleared scalp inflammation and other symptoms, but hair shedding continues. The user hopes shedding will stop as hair cycles progress.

natural substance from Neem tree with medicinal and pesticidal properties

learn sh-Polypeptide-7

How does sh-Polypeptide-7 help stimulate hair follicle activity or reduce scalp inflammation? sh-Polypeptide-7 is the INCI name for a lab-made form of human growth hormone (somatotropin) — not EGF, which is sh-Oligopeptide-1. Growth hormone and IGF-1 signalling is documented in hair follicle biology, but there is no published human trial of sh-Polypeptide-7 applied to the scalp for hair growth or scalp inflammation.

learn Bicalutamide

What results can you expect from using bicalutamide on your scalp? There is no published human study of bicalutamide applied to the scalp for hair loss, no licensed topical product and no established dose, so no result can be predicted from it. The evidence that exists is for the oral tablet in women, which is a prescription drug requiring liver monitoring and contraindicated in pregnancy.

learn Rapamycin

Is rapamycin safe for long-term use on the scalp, or should it be used in cycles? There is no published human trial of topical rapamycin on the scalp, so nobody knows whether long-term use is safe; the idea of cycling it comes from community practice and theory, not from any study or guideline, and rapamycin for hair loss is an off-label use of a prescription immunosuppressant.

learn Latanoprost

Can latanoprost be safely applied to the scalp, or is it only for eyelashes? Latanoprost is not approved for use on the scalp and its safety there has not been established: the only human scalp evidence is one 24-week pilot trial in 16 men, and clinicians flag irritation, skin darkening and unknown absorption over a large area as open risks.

learn capsicum

How does capsicum improve scalp circulation and boost growth? Capsaicin dilates blood vessels through TRPV1 activation, so capsicum is expected to raise scalp blood flow, but every human hair-loss study used it inside a multi-ingredient formula — and the strongest one gave it orally, not on the scalp — so its effect on hair by itself is unproven, and it is a known skin irritant.
