This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This review discusses the role of nanocarrier systems, such as nanoemulsions and liposomes, in delivering antioxidants into the skin to counteract oxidative stress, highlighting recent advancements in topical antioxidant therapy through nanotechnology.

This study found that subcutaneous adipose tissue-derived extracellular vesicles (AT-EVs) protect skin from photodamage by enhancing fibroblast proliferation and reducing oxidative stress compared to those from adipose-derived stem cells.

Glucocorticoid treatment in lupus can cause oral lesions, which need early diagnosis and comprehensive care.

This study found that using PRP with the FUE method of hair restoration led to better graft survival, aesthetic outcomes, and patient satisfaction compared to not using PRP.

This review highlights the potential of exosomes as a novel therapeutic approach for skin diseases and aging, due to their stability, transportability, and ability to carry various bioactive compounds to target cells.

This study highlights promising methods for converting food waste into valuable resources such as biogas, bioethanol, biodiesel, fertilizers, and antioxidants through processes like fermentation and anaerobic digestion, emphasizing the need for robust large-scale technologies to optimize this "waste to value" transformation.

This review discusses various therapeutic options for frontal fibrosing alopecia and highlights the need for more research, as existing data are largely retrospective and lack precise treatment guidelines.

This study examines the effects of excessive or prolonged exposure to blue light on retinal function and highlights its potential health implications, noting that both photoreceptor and intrinsically photosensitive retinal ganglion cells (ipRGCs) are particularly sensitive to blue wavelengths.

This study found that compounds from Ziziphus spina-christi roots exhibited promising antibacterial and antioxidant activities, supporting its traditional medicinal use.

This article reviews the indications for micropigmentation in dermatological conditions like stable vitiligo and alopecia, but presents no new clinical results.

This case study documents the first reported instance of bullous lichen planus/systemic lupus erythematosus overlap syndrome with initial hair loss, which improved with treatment including glucocorticoids and immunosuppressive drugs.

This study examined the age-related changes in the dermal structure of goat skin, providing baseline data on its histomorphology, histochemistry, and histoenzymology.

This study clarified and quantified the concept of hair transparency using a validated mathematical model based on measurable hair properties and consumer perception data from stylists in Japan and China.

This review discusses the use of hair cortisol concentration as a marker for chronic stress and long-term cortisol secretion in animals, highlighting its benefits and the need for standardized sampling protocols.

This study found that topical corticosteroids are the most supported first-line treatment for pediatric alopecia areata, with contact immunotherapy as the next best option.

This article reviews various studies and suggests that melatonin, produced both naturally in the skin and applied topically, may offer significant protection against environmental damage, making it a promising candidate for skincare therapies.

In this study, researchers developed an LC-MS/MS method to accurately quantify cortisone and cortisol levels in human scalp hair, finding that concentrations decrease predictably along the hair shaft, which could assist in identifying abnormal glucocorticoid exposure.

This review examines melatonin's potential effects on human skin and hair follicle pigmentation, highlighting the need to confirm findings from cell cultures in physiological tissue contexts.

In this study, researchers found that high hair cortisol levels, indicating stress in cows, were associated with certain shelter and cow-level conditions such as unclean environments and physical injuries.

This review examines recent research on melatonin's biochemical activities, particularly in skin health, but reports no new clinical results and emphasizes its potential for future medical applications.

This study found that patients with seborrheic dermatitis were more likely to have severe vitamin D deficiency compared to healthy controls.

In this study, compliance with UV protection recommendations was highest among vitiligo patients compared to those with other cutaneous immune-mediated inflammatory dermatoses, indicating a need for tailored education to improve compliance across all groups.

This study explored the potential of human hair keratin as a filtration material, finding that it may effectively absorb the pollutants diclofenac and perfluorobutanesulfonate. The researchers reported significant binding affinities through molecular simulations, supporting further investigation into keratin's use for water purification.

This study found that hair steroid analysis effectively detected increased hormone levels from both a single testosterone dose and laboratory-induced stress, revealing individual context factors like relationship status also impact hair hormone concentrations.

This paper explores how melatonin interacts with various magnetic fields, noting that it can enhance certain positive health effects or inhibit destructive processes, but may also exacerbate conditions like multiple sclerosis by intensifying inflammation.

This study observed significant differences in immune cell infiltration and gene expression across different skin sites, with the back displaying higher tolerance-promoting immune mechanisms, which may enhance epicutaneous immunotherapy outcomes.

In this study, the researchers found that the chemical composition and color of the brown seaweed *Saccharina latissima* varied significantly depending on the harvesting period, site, and cultivation method, suggesting that environmental conditions play a key role in these variations.

This study found that in lactating Holstein cows, hair from the tail switch, which grows faster and is more sensitive to cortisol changes, is ideal for measuring hair cortisol levels.

This review discusses the role of cytochrome P450 enzymes in skin metabolism and drug development for skin diseases, highlighting their importance and suggesting further research, but reports no new experimental findings.
