This study found that the presence of Malassezia fungi in the scalp's hairy roots was more pronounced in individuals with androgenetic alopecia than in healthy controls, suggesting a potential link to the condition.

This study identified that the biosynthetic pathways for coumestans in Eclipta prostrata are derived from acetate and shikimate pathways, while phenylpropanoid biosynthesis is exclusively from the shikimate pathway.

In this study, analysis of hair root status showed similar abnormalities in both primary and secondary syphilis patients, though it remains unclear if these are specific to syphilis.

This study observed morphological changes in scalp hair follicles of humans deprived of protein for 15 days, which suggests potential use in diagnosing protein-calorie malnutrition.

Lack of protein causes hair root damage, but it can be reversed by eating protein again.

This study found that somatic mosaic mutations in the doublecortin gene may cause subcortical band heterotopia in male patients, and molecular analysis using hair roots is a useful detection method.

This study found that using a 900-MHz GSM mobile phone for 15 or 30 minutes significantly increased single-strand DNA breaks in human hair root cells near the phone.

This study found a significant shift to the telogen phase in the hair growth of children with classical marasmus compared to normal children, suggesting a connection to the chronicity of the condition.

This study investigated the effects of selenium sulfide suspension on hair roots after noticing higher abnormal hair root proportions in individuals using the preparation.

This review discusses the evolution of hair plucking techniques for diagnosing hair disorders and suggests uniform methods could improve consistency in evaluating hair growth and treatment.

This study found that scanning electron microscopy can identify four specific hair morphology patterns in alopecia areata patients, offering a less invasive diagnostic option compared to punch biopsy.

This study found that adding yeast extract or coconut water to Panax ginseng root hair cultures did not increase ginsenoside levels, though coconut water increased biomass.

This abstract describes SwaLife Hair Bloom Onion Oil as a treatment designed to enhance hair health by nurturing the scalp, strengthening hair, and reducing breakage, using a blend of onion extract and herbs to offer both therapeutic and sensory benefits.

In this product description, it is reported that SwaLife Onion Shampoo combines Ayurvedic and dermatological principles to nourish the scalp, strengthen hair roots, and restore shine by using modern extraction techniques for onion extract along with other botanicals.

This source describes SwaLife Hair Bloom Onion Oil as a treatment that uses onion extract and herbs to strengthen hair, prevent breakage, and promote growth, while offering a relaxing, traditional head massage experience.

This source describes the SwaLife Onion Shampoo as an Ayurvedic-dermatological formulation intended to nourish the scalp, strengthen hair roots, and enhance hair thickness and shine through a blend of onion extract and botanicals, without reporting specific study results.

The study found that sonication washing of hair roots with fewer than 50 visible nuclei could reduce the number of nuclei available for DNA extraction and STR typing, suggesting that for laboratories focused on nuDNA analysis, a gentler washing method might be adequate.

This report describes a case where dermoscopy of shed hair helped diagnose post-COVID acute telogen effluvium by revealing depigmented club-shaped bulbs, highlighting its potential as a noninvasive diagnostic tool.

This study found that the RapidHIT™ ID system can successfully obtain DNA profiles from single hair roots, particularly those with high nuclei counts.

This study found that extracellular vesicles from low-passage dermal papilla cells may activate hair growth by delivering miR-140-5p, which downregulates BMP2 signaling, suggesting potential therapeutic targets for alopecia.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

In this study, applying G. glabra root extract to female rats resulted in faster and more extensive hair growth than minoxidil or a control treatment.

This study found that 18-β-Glycyrrhetinic acid, a licorice component, stimulated human hair follicle cell proliferation, inhibited testosterone 5α-reductase, and suppressed TGF-β1, suggesting potential for treating androgenetic alopecia by promoting hair growth and prolonging the anagen phase.

This study found that the petroleum ether extract of Glycyrrhiza glabra roots promoted faster and longer hair growth in female Wistar rats compared to minoxidil and control treatments.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

In this study, high concentrations of dihydrotestosterone and testosterone reduced the growth of human hair follicle cells in vitro, while high estradiol levels increased their growth.

The study found that Anagen grow, a herbal serum, promotes hair growth elongation and may inhibit the alpha reductase enzyme, suggesting it as a safe, effective alternative to finasteride and beneficial alongside minoxidil for reducing scalp dryness.

This study found that direct immunofluorescence of hair is a simple and non-invasive alternative for monitoring pemphigus vulgaris, matching skin biopsy results in the cases observed.

This study found that hair root sheaths can be accurately typed for erythrocyte acid phosphatase, adenylate kinase, and adenosine deaminase, consistent with blood typing results from the same donors.

This study found that applying HHORSC exosomes may enhance the hair inductivity of dermal papilla cells, potentially improving treatments for hair loss.
