Studysummary This study observed that hair follicle morphology in dairy cows changes during the peripartum period, with fluctuations in hair follicle width and anagen percentage but no overall marked changes in skin morphology parameters.

The study observed temporal changes in the skin morphology of 7 pluriparous dairy cows during the periparturient period. Hair follicle width decreased from 108.8 ± 5.9 µm in the dry period to 95.5 ± 5.5 µm at 28 days postpartum, then increased to 104.2 ± 5.3 µm at 56 days postpartum. The percentage of anagen hair follicles was highest in the dry period (41.4 ± 3.4%) and lowest at 28 days postpartum (18.5 ± 3.4%). Sebaceous gland size followed a similar pattern. Despite these changes, overall skin morphology parameters remained stable, indicating that the cows' nutritional state during the periparturient period did not significantly affect their skin morphology.

Morphological and Morphometric Study of the Androgenetic Alopecic Scalp Using Two- and Three-Dimensional Analysis Comparing Regional Differences

research Morphological and Morphometric Study of the Androgenetic Alopecic Scalp Using Two- and Three-Dimensional Analysis Comparing Regional Differences

9 citations , June 2014 in “British Journal of Dermatology”

The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.

research The Changes in the Hair Cycle During Gestation and the Post-Partum Period

34 citations , May 2013 in “Journal of the European Academy of Dermatology and Venereology”

In this study, changes in hair cycle phases during pregnancy and the post-partum period showed a rise in telogen rates after delivery, especially among non-breastfeeding women, but no drastic exaggerations were noted.

research Estrogen Leads to Reversible Hair Cycle Retardation Through Inducing Premature Catagen and Maintaining Telogen

42 citations , July 2012 in “PLOS ONE”

This study found that estrogen can cause reversible suppression of the hair cycle by inducing premature catagen and maintaining the telogen phase without damaging the hair follicle stem cell niche or the signature gene expressions of dermal papilla cells.

research Cutaneous Consequences of Inhibiting EGF Receptor Signaling In Vivo: Normal Hair Follicle Development, But Retarded Hair Cycle Induction and Inhibition of Adipocyte Growth in EgfrWa5 Mice

32 citations , January 2010 in “Journal of Dermatological Science”

In this study, Waved-5 mice with reduced EGFR signaling showed nearly normal skin and hair follicle function but experienced a transient reduction in subcutaneous fat.

research The Hair Follicle as an Estrogen Target and Source

159 citations , July 2006 in “Endocrine Reviews”

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

research Estrogens And The Hair Follicle

50 citations , May 2004 in “Journal der Deutschen Dermatologischen Gesellschaft”

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.

research An Estrogen Receptor Pathway Regulates the Telogen-Anagen Hair Follicle Transition and Influences Epidermal Cell Proliferation

154 citations , October 1996 in “Proceedings of the National Academy of Sciences of the United States of America”

This study found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.
