This review discusses the mechanisms, causes, and treatment options for telogen effluvium, noting acute cases often resolve by addressing causative factors, while chronic forms remain challenging to treat; recent causes include post-hair transplantation, vitamin D deficiency, and COVID-19.

This study evaluated a herbal anti-dandruff hair wash powder, TRICHONEMTM, composed of eighteen herbal ingredients, reporting effective in vitro anti-dandruff activity and high user satisfaction in a 4-week pilot trial involving 50 women, without causing irritation.

This study found that hair testosterone concentrations show some consistency over time, but factors like hair washing and individual growth rates influence these levels, suggesting the need for careful sampling and analysis adjustments.

This case report describes a 45-year-old unvaccinated woman who experienced severe telogen effluvium, losing over 80% of her hair, about three months after recovering from COVID-19.

In this study, adding platelet-rich plasma to minoxidil and finasteride treatment for patterned hair loss improved hair outcomes with minimal side effects compared to using minoxidil and finasteride alone.

In this study, using sterile gloves during hair restoration surgery did not reduce scalp contamination compared to clean gloves due to the natural microbiome of the scalp.

This study found that NB-002, a novel topical antifungal, showed significant antifungal activity and clinically meaningful nail clearing in patients with mild to moderate distal subungual onychomycosis.

Genetic testing for cancer risk can lead to early and life-saving treatments in people without symptoms.

In this study, researchers found that while chest hair can be a reliable alternative to scalp hair for ethylglucuronide testing, seasonal factors may affect concentration levels and should be considered in result interpretation.

In this review, the authors highlight the occupational risks faced by pregnant urologists, such as radiation and exposure to certain medications, and emphasize the importance of avoiding specific drugs and practicing good hygiene, but note limited data on radiation risk.

This article discusses various treatments for primary cicatricial alopecia with a focus on early intervention to manage symptoms and improve hair density, but it reports no new clinical results.

This study found that washing hair with surfactants reduces the internal density of hair due to cuticle lifting, and suggests that a cuticle-sealing strategy can inhibit this effect and maintain hair homeostasis.

This study found that daily hair washing was associated with significantly lower hair cortisol concentrations, suggesting it may influence the accuracy of using hair cortisol as a biomarker for chronic stress.

This study found that while hair washed with hard water had higher magnesium deposits, it did not show significant structural surface changes compared to hair washed with soft water.

The document concludes that scalp disorders can be treated with hair washing, specific shampoos, medications, and sometimes surgery or hair transplants, but hereditary baldness is untreatable.

Hair cortisol levels can indicate stress and are affected by washing frequency, not cosmetic treatments.

This study found that patients with telogen effluvium who delayed hair washing or collected shed hair were more likely to have higher clinical severity and increased disease-related economic burdens, suggesting these behaviors can aid clinical assessments.

In this study, gamma benzene hexachloride washes successfully resolved skin disease in guinea pigs affected by Trixacarus caviae, after confirmation via skin scrapings.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.

In this study, researchers found that the wash method can effectively differentiate between chronic telogen effluvium and early female androgenetic alopecia, potentially negating the need for scalp biopsy.

This paper reviews chemical analysis methods for trace elements in human hair and supports a no-wash policy due to challenges in distinguishing between endogenous and exogenous element sources.

This study quantified hair shedding in women without female pattern hair loss and found that about 40% experienced excessive shedding during hair washing, emphasizing the need for further research into this common concern.

In a study involving adults with mild to moderate dandruff, researchers observed that post-hair wash interventions significantly reduced dandruff as measured by three assessment methods, showing substantial reliability and correlation, which supports their use in clinical settings for evaluating scalp dandruff treatments.

This study surveyed hair care practices among men and women in India, finding that most wash their hair weekly and use shampoos, but highlight the need for education on proper cleansing methods.

This study explored using tyrosine as a cross-linking agent for curling Asian hair and found that it could shape hair effectively before washing without damaging the fibers, though the method was less effective after washing compared to commercial products.

This study found that a sucrose-based crosslinker can effectively straighten hair and maintain durability in high humidity and through repeated washings without affecting the hair's tensile properties or causing surface damage.

This promotional piece discourages specific hair restoration methods in Bremerton City, Washington, and provides no research findings or clinical results; readers are encouraged to call a specialist for more information.

In this study, researchers evaluated the hair pull test and found that normal values should be reduced to two hairs or fewer, with no significant impact from hair washing, brushing, or lifestyle factors such as hair texture and medication use.

This study found that a caffeine-containing shampoo penetrated deeply into hair follicles in just two minutes and remained there for up to 48 hours, even after washing.

This case report highlights that a postmenopausal woman experienced virilization due to unintentional transdermal absorption of testosterone from her spouse's topical androgen via shared washcloths, underscoring the importance of considering exogenous androgen exposure in similar diagnoses.
