This study found that flavonoids with two hydroxyl groups in their B-ring, such as sterubin and luteolin, supported the regeneration of pigmented hair after skin injury, unlike those with one hydroxyl group.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

This study observed that nicotinamide can effectively inhibit human hair growth and promote hair follicle regression in cultured human scalp models without negatively affecting epidermal vitality, suggesting its potential as a hair growth inhibitor in cosmetic applications.

This article describes a case of oral pigmentation that posed a diagnostic challenge in determining Addison’s disease and includes a brief review, reporting no new clinical results.

This review evaluated the evidence on skin disorders linked to levodopa treatment for Parkinson's disease, suggesting a possible association with melanoma, though evidence remains inconclusive and further studies are needed.

This article discusses the relationship between anemia and skin disease but does not present new research findings.

In this study, sensorineural hearing loss was significantly more frequent in patients with alopecia areata compared to healthy controls, suggesting a relationship between the autoimmune condition and hearing function.

This review summarizes the ophthalmic complications of common periocular aesthetic treatments but reports no new clinical findings, emphasizing the importance of recognizing potential side effects.

This article discusses a case of patchy alopecia areata that spares greying hairs but reports no new findings; it refers to existing literature for context.

Some oils can penetrate hair and reduce the stickiness between fibers, but mineral oil cannot.

This study concluded that the process of mummification disfigures facial features, making identification challenging, but commercial shrunken heads retain more defining features compared to ceremonial ones.

This study reports that the white rhinoceros has a unique integumentary structure among large herbivores, characterized by thick epidermis, organized collagen bundles, and the presence of coiled sweat glands.

In this study, a square pulse, low-fluence IPL device used at home significantly reduced terminal hair count by 87% six months post-treatment, with evidence of hair miniaturization similar to professional laser treatments.

In this study, a new IPL device effectively reduced hair regrowth with high patient satisfaction, particularly in individuals with coarse dark hair and darker skin, despite repeated sessions needed for lighter hair and skin.

This study reported that long-pulse alexandrite laser treatment achieved an overall hair reduction rate of 80.8% among patients, with minimal cases of hypo- or hyperpigmentation.

This article reviews the causes of hair loss in pediatric and adult populations, emphasizing the importance of distinguishing between primary dermatologic conditions and those related to systemic diseases, but reports no new clinical findings.

This report observed that two teenagers developed skin issues, including abscess-like pustules, after taking kelp supplements, which cleared when the supplements were discontinued.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

This study found that overexpression of sFRP4 in skin cells reduces Wnt signaling activation, leading to decreased melanocyte differentiation in regenerating hair follicles.

Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.

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.

In this study, RT1640 was found to promote hair pigment system regeneration and expand melanocyte stem cell pools in a mouse model, suggesting potential applications for aging-related hair disorders.

This study found that stress-induced signaling from the sympathetic nervous system in mice led to the depletion of stem cells in hair follicles, resulting in premature greying.

This article reviews the anatomy and pathology of skin and hair to aid in diagnosing skin diseases and discusses potential therapies, without reporting new clinical results.

This study found that while yak belly hair is chemically similar to human hair, its higher porosity and lower mechanical strength limit its usefulness as a substitute in hair dye development.

This study found that premature greying of hair was reported in 42.5% of young adults from King Faisal University, with higher prevalence among females, and noted associations with various health and lifestyle factors.

This article explores the potential of photobiomodulation for coronary health, suggesting protective effects after heart attacks and in inaccessible ischemic heart conditions, but presents no new clinical results.

This abstract does not provide research results or a summary of findings, but only lists author affiliations and contact information.

This study found that non-ionic silicone emulsion best protected hair color from UV-induced fading, outperforming honeysuckle extract and benzophenone-3, with significant effects in both dyed and virgin hair.

This study found that intense pulsed light treatment primarily targets pigmented structures in hair follicles and may damage dermal papilla cells at high energy levels, but stem cells are mostly spared.
