research A chemist's view of the analysis of human hair for trace elements

109 citations , January 1980 in “Science of the total environment”

This paper reviews chemical analysis methods for trace elements in human hair and supports a no-wash policy due to challenges in distinguishing between endogenous and exogenous element sources.

research Preliminary Studies for ^|^ldquo;Biomedical Analysis of Human Hair Exposed to Long-term Space Flight (Hair)^|^rdquo; Project: An Analysis of Trace Elements in the Hair

January 2012 in “TRANSACTIONS OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES AEROSPACE TECHNOLOGY JAPAN”

This paper outlines the research plan and current progress of a study analyzing mineral metabolism changes in astronauts by examining hair shafts after long-term space flight, with no new results yet.

community Hair cloning breakthrough, this might just be the big one ?

418 upvotes 6 months ago

Japanese scientists discovered ABM cells, enabling successful human hair follicle cloning, potentially curing hair loss. The treatment may be available in Japan by 2028, but it will be expensive and require travel.

community Why liposomal finasteride and minoxidil may be better than traditional topical solutions.

in Research/Science 2 upvotes 1 year ago

Liposomal formulations of finasteride and minoxidil may enhance drug delivery to the skin and hair follicles more effectively than traditional solutions, potentially improving treatment outcomes. However, more human clinical trials are needed to confirm these benefits.

community Some UFO/Alien enthusiasts believe that bald Grey Aliens are just time traveling humans from the future. That better not be true. I think you all know where I'm going with this.

41 upvotes 1 year ago

The conversation humorously speculates that bald Grey Aliens might be future humans who haven't solved baldness, despite advanced technology. Treatments like microneedling, minoxidil, and finasteride are mentioned as potential solutions.

community Justin Trudeau really is one lucky guy

in Satire 233 upvotes 1 year ago

Justin Trudeau's full head of hair at 53 is humorously attributed to unpredictable genetics and possible use of finasteride. The conversation jokes about a resemblance to Fidel Castro, suggesting genetic luck or treatment use.

community Why is Kopexil (trade name Aminexil) not approved as a drug in the US and Europe?

3 upvotes 10 months ago

Kopexil (Aminexil) is not approved as a drug in the US and Europe because it is marketed as a cosmetic, which requires less testing and regulation. L'Oreal's 1.5% Aminexil is noted to reduce hair shedding, but its efficacy as a drug is not proven.

learn Valproic acid

How is valproic acid being explored differently in topical hair products compared to its traditional oral medical use? Topical valproic acid is being studied for local effects on the hair follicle rather than the whole-body effects of the oral drug. The human evidence is one small randomized 24-week trial of an 8.3% spray; no topical valproate product is approved for hair loss.

extract, clone, and reinsert your own hair cells

learn Osteopontin

signaling protein that, when suppressed, may grow hair by reducing inflammation and stem cell loss

learn Rapamycin

mTOR regulator and immunosuppressant used more recently for anti-aging and hair regrowth

learn Neem Oil

natural substance from Neem tree with medicinal and pesticidal properties

learn Lavender

plant and natural oil with antimicrobial and some anti-androgenic effects

learn Vitamin B1

Thinning hair over time? It might not just be genetics: lack of B1 and B2 could be silently working against you. There is no verified human trial showing that B1 or B2 deficiency causes thinning hair or that correcting it regrows hair; a 2019 review concludes the role of micronutrients in hair loss is real but unclear and still needs controlled trials.

learn RU58841

Will I lose my hair if I stop using RU58841? (Spoiler: I might.) There is no published human trial of stopping RU58841; community members commonly report shedding within weeks to months, and androgen biology suggests miniaturization would resume once the topical anti-androgen is withdrawn.

learn Castor oil

Does castor oil make hair grow or is it just a myth? There is no published human trial showing castor oil grows hair. It can make hair look and feel better by reducing breakage and adding shine, which is easily mistaken for growth, and it is not approved anywhere as a hair loss treatment.

learn Redensyl

Does Redensyl prevent hair loss or only help when there's already visible hair loss? The only human data on Redensyl is a small, unpublished manufacturer study in men who already had androgenetic alopecia; there is no evidence in people without visible hair loss, so nothing supports using it to prevent hair loss before it starts.
