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

Minoxidil reacts to nitrosation 7 times more than phenol, mainly due to its -NH₂ groups, leading to the creation of N-nitrosominoxidil.

This study found that CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

This study suggests that label-retaining cells in the hair follicle contribute to follicular renewal, indicating a specific role in the hair cycle by proliferating during the late telogen phase.

In a study using a mouse model, HF-MSCs were reported to enhance ovarian function in cyclophosphamide-induced premature ovarian failure more effectively than HU-MSCs, potentially by preventing ferroptosis in granulosa cells via the KEAP1/NRF2/HO-1 pathway.

In this study, researchers observed that Malassezia species show different lipid metabolism and growth patterns depending on pH, with slightly acidic conditions promoting beneficial lipid bio-conversion for skin health, while neutral pH resulted in lower growth and lipid content, potentially negatively impacting the skin.

This study found that injecting keratin into the skin of mice promoted hair growth, potentially through keratin's interaction with hair-forming cells and changes in the microenvironment.

This study observed that silver nanoparticles synthesized using Laurus nobilis leaf extracts significantly inhibited protein denaturation and membrane stabilization in vitro, suggesting potential as a basis for novel antiarthritic drugs.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study found that silk fibroin/sodium alginate scaffolds seeded with dermal papilla cells may accelerate skin repair and hair follicle regeneration in a rat model.

This study suggests that porphyra-334 may have antiaging properties, promoting collagen synthesis, improving periorbital wrinkles, and supporting hair follicle growth through gene regulation.

In this study, researchers demonstrated that human hair keratins can self-assemble into stable nanofibrous networks in vitro, which are compatible with human skin cells and useful for regenerative applications.

This study found that stress plays a significant role in altering phenotypic features and body composition among PCOS patients, potentially worsening due to the COVID-19 pandemic.

This study identified novel 4-Amino-2H-benzo[h]chromen-2-one analogs as potent androgen receptor antagonists that show strong antiproliferative activity against prostate cancer cells, suggesting them as potential lead compounds for therapy development.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

This study assessed minoxidil solubility in propylene glycol and water mixtures, comparing cosolvency models and examining thermodynamic properties, without reporting new clinical results.

This study suggests that synthetic ceramides may promote hair growth by inducing proliferation of human dermal papilla cells through modulation of Wnt/β-catenin and BMP2/4 signaling pathways.

This study found that Adiantum capillus-veneris extract exhibited significant antidepressant and anti-anxiety effects in rats, likely due to its antioxidant and anti-inflammatory properties.

This study found that Phyllanthus urinaria extract displayed significant anti-alopecia properties in a mouse model, showing potential as an anti-5α-reductase agent for androgenic hair loss.

This study evaluated a new anti-baldness product, IPSTiC patch hair, designed to treat androgenetic alopecia, and reported that it effectively inhibits NO radical and 5α-reductase activity while maintaining safety and stability, suggesting its potential for topical use.

This study found that the medulla of Japanese hair contains unsaturated lipids such as squalene and oleic acid, which may contribute to hair glossiness.

This study found that 6-Gingerol significantly suppressed hair growth in mice by reducing hair follicle number and length, potentially through increased expression of MMP2 and MMP9.

This study found that biodegradable hyperbranched polyesters improved the solubility and loading capacity of hydrophobic drugs, with complete pyrene release achieved in 16 days under enzymatic conditions.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study suggests melatonin may promote cashmere growth in Inner Mongolian cashmere goats through the nuclear receptor RORα, with a noted mRNA expression difference in December compared to other months.

In this study, the researchers optimized a method for culturing melanocyte precursors from hair follicles and found that 1,25-dihydroxyvitamin D3 significantly promotes their differentiation and melanin synthesis.

This study found that mice lacking CD61 had significantly shorter lower incisors compared to wild-type mice, suggesting CD61 is crucial for proper tooth growth and pre-ameloblast proliferation.

In this study, researchers used a murine model of irritant contact dermatitis to reveal that hair follicle regions serve as key sites for neutrophil transepidermal migration, which requires MMP-9 expression stimulated by dermal monocytes.

This study demonstrated that CEP may effectively treat pulmonary fibrosis by inhibiting fibroblast activation through regulating macrophage M2 polarization and decreasing fibrosis-associated factors, suggesting a new avenue for future research in this area.

In this study, treatment with recombinant DKK2 was shown to significantly stimulate hair progenitor cell growth and enhance hair shaft elongation in ex vivo human hair follicle cultures by activating the Wnt/ẞ-catenin signaling pathway, suggesting a potential role for DKK2 in promoting hair growth.
