This study found that a marine-extract dietary supplement significantly reduced hair shedding and increased hair diameter in premenopausal women with subclinical hair thinning or hair loss after 6 months of use.

This study found that an oral marine protein supplement significantly increased hair growth and reduced hair shedding in women with temporary thinning hair over 90 days compared to a placebo.

In this controlled study, a 6-month treatment with the nutraceutical product ViviScal® reduced telogen hair fibers and increased total hair fibers in 83% of participants with Telogen Effluvium, who also reported improved hair and nail growth, skin appearance, and overall quality of life.

This review of clinical data found that an oral marine supplement increased hair growth and thickness while reducing hair loss in women and men with thinning hair, suggesting it is a safe and effective treatment.

In a murine model of alopecia areata, this study observed that the IL-2 fusion protein HCW9302 helped prevent disease development by expanding regulatory T cells and reducing disease-causing effector T cell infiltrates, suggesting potential for using IL-2 fusion proteins in alopecia areata treatment.

This study found that overexpressing the PML protein in transgenic mice decreased skin tumor occurrence and delayed their progression, highlighting PML's potential role in influencing keratinocyte growth and differentiation.

This study found that mrp/plf-mRNA expression in murine skin increases in response to different tumor promoters, suggesting its potential as a short-term biomarker for chemical carcinogenesis.

In this study, elevated mRNA levels for serine-rich ultra high sulfur proteins were observed during active hair growth phases in mice, particularly in the forming hair structures and upper skin layers.

This study found that feeding mice a high-fat diet with fish oil leads to hair loss through a mechanism involving omega-3 fatty acids and TNF-α signaling, with epidermal fatty acid binding protein playing a key role.

In this study, researchers found that in mice, gonadal hormones and biological sex do not affect the expression of SARS-CoV-2 entry proteins ACE-2 and TMPRSS-2 in the respiratory tract, regardless of disease state.

This study found that mu-crystallin gene expression in mouse skin is highest during the anagen phase of hair development, suggesting its possible role in hair follicle growth.

This study suggests that hair loss disorders like Marie Unna hereditary hypotrichosis may result from mutations that disrupt post-transcriptional regulation of HR protein expression by PCPB2 interacting with Hr mRNA.

This study reports a mutation in the U2HR gene causing Marie Unna hereditary hypotrichosis in a Turkish family and notes eyebrow loss as a diagnostic clue.

This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.

This study explores the potential of seaweeds as a source of bioactive compounds for food, cosmetics, and medical applications, while highlighting concerns about toxic element accumulation and suggesting purification and nanoencapsulation techniques to enhance safety and stability.

Marine-derived ingredients show potential for hair health but need more human trials to confirm effectiveness.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study found that rete ridge morphogenesis in mammalian skin is directed by a BMP-dependent developmental program, which is evolutionarily distinct from other known pathways controlling the development of hair follicles, sweat glands, and fingerprint ridges.

In this study, researchers found that a scallop adhesive protein (Sbp9 Δ) forms strong adhesive coatings via disulfide-sticker strategies, which also promote hair regeneration in mouse models by activating Wnt signaling and enhancing angiogenesis, proving more effective than minoxidil for androgenetic alopecia.

This study developed a validated murine model of hypertrophic scar contraction, demonstrating similarities to human skin and observing graft contraction and tissue characteristics over time.

This study found that MPZL3 plays a crucial role in controlling sebaceous gland size and sebocyte proliferation in mice and humans, implicating its potential involvement in skin disorders like acne and psoriasis.

This study reports that aging in mice leads to curved hair follicles and an increase in white hairs, potentially due to changes in keratinocyte and melanocyte stem cells.

In this study, mouse models of 22q11.2 deletion syndrome showed that growth issues in small embryonic thymuses were linked to mesenchymal cells, which could be corrected by substituting with normal mesenchyme.

This study found that the switch-off of melanogenesis during the hair cycle in C57 BL-6 mice is a gradual and stochastic process starting in mid anagen VI, with specific biochemical markers indicating the transition to catagen.

This study found that exposure to 12-O-tetradecanoyl-phorbol-13-acetate in mouse skin caused changes in claudin expression and localization, indicating disruption and eventual recovery of the epidermal barrier.

This study found that transgenic mice expressing cgVEGF164 had increased hair follicle diameter and density, potentially linked to higher phosphorylation levels of ERK1/2, AKT1, and LEF1 proteins.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.

This study suggests that MPZL3, a mitochondrially localized protein, may play an integral role in regulating hair follicle cycles, with potential therapeutic implications for hair growth disorders if findings translate to humans.

This study reported that in a mouse model, Negative Pressure Wound Therapy promotes wound healing by modulating inflammatory responses and increasing dickkopf-related protein 1, which encourages the differentiation of Hair Follicle Stem Cells into epidermal cells.
