Sample Collecting Methods for Bacterial Community Structure Analysis of Scalp Hair: Non-Invasive Swabbing Versus Intrusive Hair Shaft Cutting

research Sample collecting methods for bacterial community structure analysis of scalp hair: non-invasive swabbing versus intrusive hair shaft cutting

1 citations , September 2024 in “Scientific Reports”

This study observed that bacterial communities on scalp hair collected through non-invasive swabbing showed similar diversity and composition to those obtained by cutting or removing hair, suggesting that swabbing is an effective method for microbiome analysis on hair.

research Proteomic analysis of hair shaft and nail plate.

29 citations , August 2011 in “PubMed”

This study describes how shotgun proteomics can identify over 300 proteins in hair shafts, potentially allowing for the diagnosis of diseases through noninvasive human proteome sampling.

Peer Review of Human Hair Shaft Proteomic Profiling: Individual Differences, Site Specificity, and Cuticle Analysis

research Peer Review #2 of "Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis (v0.1)"

August 2014

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

research Peer Review #1 of "Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis (v0.1)"

August 2014

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

research Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis

68 citations , August 2014 in “PeerJ”

This study found that proteomic analysis can distinguish hair samples across different ethnicities and body regions based on keratin protein levels, which may aid forensic hair identification.

community Weed/THC effects on hair growth/hair loss, and vitality of organ-culture human follicle studies (research review)

4 upvotes 1 year ago

Cannabis and THC may have mixed effects on hair, with some studies suggesting potential negative impacts on hair growth in isolated hair follicles, but these results are hard to apply to living humans. Treatments like minoxidil and finasteride are commonly used for hair loss, and the effects of cannabis might be neutral or vary based on individual factors.

community Solving Hair Loss with Research at MIT

in Research/Science 595 upvotes 1 year ago

Hair loss treatments like minoxidil, finasteride, TDM-105795, and PP405. MIT is hosting a hackathon to find innovative hair loss solutions.

community End of Hair loss ( AGA ) ? Since they produce it in china probably we don’t need to wait other 10 yrs😁

276 upvotes 6 months ago

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.

community PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

67 upvotes 11 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.

community Accelerated Hair Loss from Creatine

137 upvotes 10 months ago

Creatine may cause hair loss in some individuals, especially those on finasteride, despite no scientific link. Personal experiences suggest individual sensitivity to DHT could be a factor.

learn Cetirizine

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.
