This study developed a partially automated protocol utilizing hair follicles for DNA extraction in marmosets, achieving reliable whole genome sequencing with low chimerism, offering an efficient alternative to blood for genetic studies in non-human primates.

This study found that regardless of alopecia type, follicular unit extraction resulted in good patient satisfaction concerning appearance and visual age.

This study comparatively evaluated different extraction techniques for Schinus terebinthifolius Raddi leaf extracts and found that conventional extraction with ethanol yielded the highest antioxidant activity and beneficial effects on skin cell viability, supporting its potential use in sustainable cosmeceutical formulations targeting skin aging.

This study found that Cerasus serrulata extracts, when obtained through specific methods, demonstrate significant antioxidative and antibacterial properties, as well as potential anti-alopecia effects in a mouse model, potentially making them useful supplements for these purposes.

A man unhappy with his old hair restoration got a new, natural-looking hairline using a combination of follicular unit extraction and punch graft reduction.

This study found that partial follicular units extracted from the donor area can survive and regenerate new hairs at their original site and when transplanted, effectively creating two hair follicles from one.

The conclusion is that a new method can measure caffeine and drugs in hair, finding caffeine abusers have 70 times more caffeine than normal, with a proposed cut-off value for abuse.

This review explores the diverse roles of rosemary, covering its nutritional and medicinal uses, cosmetic and pharmaceutical applications, and evaluates various extraction methods, with a focus on sustainable practices and commercial prospects.

This review highlights that pomegranate exhibits promising beneficial effects in preclinical and clinical studies for cardiovascular and non-cardiovascular diseases, though further research is needed on its bioavailability and metabolites for effective therapeutic use.

This study found that a new method using enzymatic laundry powder effectively extracts DNA from hair shafts, showing promise for genome-wide DNA analyses.

Sampling methods greatly affect skin microbiome data in acne studies.

This article discusses the potential of a robotic surgical device to overcome limitations of traditional hair restoration methods, but reports no new clinical results and calls for further testing.

This article discusses a combined strip and follicular unit extraction method along with an intraoperative calculation model to reduce over-extraction and wastage in hair transplantation and reports no new clinical results.

Method detects finasteride in plasma at very low concentrations.

This article reviews factors affecting follicular unit extraction, emphasizing the need to tailor procedures to individual patient characteristics, but reports no new experimental findings.

This study developed and validated a method using hair samples to simultaneously detect bisphenols and parabens, enabling the quantification of these endocrine disruptors in a hospital population’s hair.

This study found that both FUE and FUT methods are equally effective in producing high-quality hair grafts, with FUE offering the advantage of less noticeable scarring compared to FUT.

The document concludes that hair transplant methods are often selected for provider convenience over patient benefit, highlighting the need for less invasive techniques and careful physician involvement for better results.

In this study, researchers found that the Shindai method effectively extracts keratin from human hair, with female hair yielding more keratin than male hair. The extracted keratin showed high absorption with UV spectrometry and was confirmed as α-keratin through SDS-PAGE analysis.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

This study developed and validated a Gas Chromatography-Flame Ionization Detection method for assessing minoxidil, which shows good precision, accuracy, and specificity for quality control and pharmacokinetic studies.

This study found that while parabens in haircare products were within legal limits, all samples contained dibutyl phthalate, raising concerns about chronic exposure to endocrine disruptors.
