research A partially automated method for DNA extraction from marmoset hair follicles to avoid blood chimerism

September 2025 in “Frontiers in Genetics”

This study developed a non-invasive, partially automated protocol for extracting high-quality DNA from hair follicles of marmosets, significantly reducing chimerism rates compared to blood, and proving reliable for whole genome sequencing in low-input DNA scenarios.

September 2025 in “OPAL (Open@LaTrobe) (La Trobe University)”

In this study, researchers developed a non-invasive, partially automated protocol for extracting DNA from marmoset hair follicles, resulting in high-quality whole genome sequencing with low chimerism levels, making it a reliable method compared to blood DNA sequencing in these primates.

research A Mosaic Hotspot PLCD1 Variant, Detectable in Blood‐Derived DNA, Associated With Nevus Trichilemmocysticus

March 2025 in “American Journal of Medical Genetics Part A”

In this study, researchers found that mosaic PLCD1 hotspot variants, even without the recognized germline "risk allele," may be a rare but significant genetic cause of nevus trichilemmocysticus, warranting DNA testing and sensitive sequencing technologies for accurate diagnosis.

in Is this regrowth? 11 months ago

The user shares their experience with hair loss treatments, including oral finasteride, oral minoxidil, and a topical lotion for dandruff, expressing dissatisfaction with past treatments like PRP and hair transplants. They seek advice on a DNA test to determine suitable medications and express frustration with dermatologists' advice.

community Do you Have Poor Posture? Maybe Contributing to Hair Loss , Esp Diffuse Thinning

in Research/Science 16 upvotes 3 weeks ago

Correcting posture may improve hair health by enhancing blood circulation and reducing side effects like bloating and sexual issues. The user has been using minoxidil and finasteride for two years with underwhelming results and is exploring posture correction as a potential aid.

community Is this true? It can be a major breakthrough

1008 upvotes 5 months ago

Deoxyribose sugar gel may stimulate hair regrowth similarly to minoxidil by enhancing blood supply and follicle activity. Human trials are necessary, and current products have mixed results.

Can products that stimulate Vascular Endothelial Growth Factor (VEGF) improve blood flow to hair follicles? Yes, products that stimulate VEGF may improve blood flow to hair follicles.

learn Centella

Ever wonder why your hair doesn’t grow back thick anymore? Maybe your scalp needs better blood flow: centella could help. There is no clinical trial of centella asiatica for hair loss and no study measuring scalp blood flow in people using it; the only hair-related evidence is a 2017 cell-culture study. Centella products are cosmetics that may soothe an irritated scalp, and the link between scalp circulation and pattern hair loss is itself unproven.
