,
October 1971 in “The BMJ” The document suggests that hair loss after stopping birth control may be similar to post-pregnancy hair loss and could recur with future pregnancies.
234 citations

December 1996 in “Journal of The American Academy of Dermatology” The authors concluded that chronic telogen effluvium in middle-aged women presents distinct clinical and histological features that differ from androgenetic alopecia and acute telogen effluvium.
57 citations
,
November 1987 in “Pediatric Dermatology” This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.
47 citations
,
July 2005 in “British Journal of Dermatology” This study found no protective effect of topical calcipotriol on hair loss in chemotherapy patients, and the authors propose the term "atrophic telogen effluvium" for this type of hair loss.
24 citations
,
March 1995 in “British Journal of Dermatology” This study reported that etretinate treatment leads to increased hair shedding due to a sustained decrease in anagen duration, with an arrest at the onset of anagen and a follicular anchorage defect in telogen contributing to alopecia.
January 2018 in “Springer eBooks” Telogen effluvium is hair loss caused by disruption of the normal hair cycle.
November 2001 in “CRC Press eBooks” This article discusses how metabolic imbalances can trigger telogen effluvium by causing hair follicles to prematurely enter the shedding phase, and includes no new research findings.
October 1971 in “The BMJ” Hair loss can be linked to hormonal changes, and physical conditions like heart defects can cause depression.
June 2026 in “Current Oncology Reports” This review highlights the potential of Sacituzumab Tirumotecan, an antibody-drug conjugate, in treating gynecologic cancers, with ongoing Phase III trials indicating a manageable safety profile and future results expected to shed light on its effectiveness in improving survival and response rates.
2 citations
,
August 2002 in “Zeitschrift für Hautkrankheiten” This review discusses the concept of telogen effluvium and emphasizes that its diagnosis requires detailed clinical evaluation and tests to identify underlying causes; no new clinical results are reported.
In this correspondence, the authors reported that patients on a 500-calorie crash diet with rapid weight loss experienced significant hair loss, which began months after dieting and gradually improved.
November 2005 in “Nature Reviews Molecular Cell Biology” In this study, researchers discovered that the interaction between the hairless protein and the wise protein is crucial for hair-follicle regeneration, helping bald mice regrow fur.
8 citations
,
October 2017 in “Dermatology practical & conceptual” This study found that a spermidine-based nutritional supplement increased the number of anagen phase hair follicles in healthy humans, suggesting potential benefits for hair loss conditions.
February 2010 in “Journal of The American Academy of Dermatology” Mimicking growth factors in a topical solution can prolong hair growth phase and reduce hair loss without side effects.
1 citations
,
July 2020 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.
1 citations
,
April 2018 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that topical patidegib gel significantly shrank basal cell carcinomas in Gorlin syndrome patients without causing the systemic side effects common with oral hedgehog inhibitors.
92 citations
,
June 2010 in “Journal of The American Academy of Dermatology” This study found that 0.5 mg of dutasteride significantly improved hair growth compared to placebo and was well tolerated over six months in men with male pattern hair loss.
83 citations
,
May 1999 in “International Journal of Dermatology” Hair loss that spreads out can often fix itself or be treated by finding and handling the cause.
34 citations
,
June 1990 in “British Journal of Dermatology” This study found that etretinate treatment led to an increase in plucked telogen hair counts, suggesting a reduction in the duration of anagen as the primary cause.
4 citations
,
