This article reviews the empirical use of algae in traditional remedies and highlights the need for scientific understanding of algae's bioactive compounds used in cosmetics without providing new experimental results.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

In this study, seasonal hair loss was most pronounced in low-ranking male vervet monkeys, and changes in scrotal color and hyperpigmentation also correlated with hair loss, but underlying causes were not identified.

This study reports that hair growth and shedding in healthy women show annual seasonal patterns, with the highest shedding in summer and a less pronounced peak in spring.

This study found that in male badgers, seasonal molting and hair growth are influenced by cycles of plasma testosterone and thyroxine, with hormones affecting the timing and progression of these processes.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This study found that administering melatonin to ferrets can advance the timing of fur growth and reproductive cycles influenced by daylength and hormonal control.

In this study, androgen receptors were found only in the mane follicles of red deer stags during the breeding season, suggesting their expression is induced by seasonal hormone changes.

This study observed that nutritional stress is likely responsible for changes in Merino sheep follicle morphology in Mediterranean environments, affecting staple strength and possibly requiring targeted management strategies.

In this study, researchers observed that purpuric, telangiectatic, lichenoid balanitis was the most common histologic pattern in cases of chronic pseudoerythroplastic balanitis, suggesting a possible link to lichen aureus.

This study found that seasonal changes significantly affected hair follicle activity and fibre growth in Merghoz goats, with variations seen in feed intake and growth patterns across different seasons.

In this retrospective study of 123 pediatric alopecia areata patients, hair loss episodes were most frequent in winter and showed significant correlations with air pressure and hours of sunlight, especially in non-atopic individuals, suggesting a role for climate factors in seasonal hair loss patterns.

This study found that Dendropanax, sea salt, spinach, and kelp were safe and potentially effective as ingredients in functional cosmetics aimed at alleviating hair loss symptoms.

In this study, the authors reported that Sargassum wightii seaweed-based biostimulants improved soil quality and enhanced rice plant growth and yield by ameliorating acid soil effects, boosting antioxidant enzyme activity, and facilitating nitrogen uptake, photosynthesis, and water use efficiency.

This study found that environmental conditions significantly influenced rabbit coat quality, while dietary linseed oil supplementation changed the fatty acid profile but did not improve coat thickness or heat protection.

This study proposes that seasonal alopecia and reproductive changes in six female fossas at the San Diego Zoo may be linked to hormonal changes associated with reproductive activity.

This study reported that a specific mixing ratio of Dendropanax extract and sea salt showed low cytotoxicity, high cell proliferation, anti-inflammatory, and antimicrobial effects, suggesting potential for functional cosmetics against hair loss.

In this study, the expression of certain hair follicle-related genes differed between growth phases in Angora goats, with HOXC13 showing overexpression during the anagen phase, potentially influencing the mohair's shine and texture.

In this study, seborrheic dermatitis was most prevalent among middle-aged adults and men, with patient presentations peaking during the winter months.

This study observed that adult male raccoon dogs undergo seasonal moults, with winter fur maturing by the end of November after significant hair growth in spring and autumn.

This study observed seasonal trends in Poland's Google searches for dermatology-related terms and noted a decrease in searches for sexually transmitted diseases despite rising infection rates, highlighting a need for better sexual education.

This study found that Malassezia pachydermatis was present on both lesion and healthy skin in a California sea lion, with significantly more colonies on the lesion site.

This study suggests a potential genetic component in CFA among Ridgeback dogs, but MLPH genotyping did not identify the MLPH gene as a contributing factor.

In this study, researchers observed that the skin quality and hair follicle development of Rex rabbits improved when slaughtered in winter compared to summer, with findings suggesting seasonal regulation via multiple signaling pathways affecting fur characteristics.

This study found that Magra sheep with high-luster wool exhibited significantly higher expression of keratin genes, suggesting that increased keratin protein levels may be crucial for wool luster.

Hair loss is more common in summer and fall.

Sea holly extract may help reduce hair loss.

This study found that the Dongeui Hot Spring Water complex (Dongui Hot Spring Water CPX), containing sea slug extract and panthenol, demonstrated higher antioxidant activity and cell proliferation, suggesting potential benefits for preventing hair loss and improving scalp health.

In laboratory conditions, this study found that the Dongeui Hot Spring Water Complex, containing sea slug extract, demonstrated enhanced antioxidant activity and promoted hair papilla cell proliferation compared to a control, suggesting potential benefits for scalp health and hair loss prevention.

This study evaluated sea cucumber extract as a scalp cosmetic and found that it effectively improved oil-moisture balance, hydration, redness, and hair shine on the scalp. The authors recommend further research into its antioxidant properties for scalp care.
