In this study, purebred Dexter cows with higher levels of winter hair shedding weaned heavier calves and had better reproductive success compared to cows with lower shedding levels.

In this study, insulin-like growth factor-1 did not impact hair follicle elongation in rat pelage hair follicles, while transforming growth factor-beta 1 inhibited both elongation and thymidine uptake.

This study describes a simplified method for isolating and cultivating human hair follicle papillae that can be easily executed by new lab personnel.

In this study, goat hair follicles cultured in serum-free medium grew faster than those in medium with serum, and growth rates increased with the addition of VEGF and EGF.

This study found that soluble factors secreted by ovine dermal papilla cells enhance the aggregative behavior of human dermal papilla cells, potentially improving their follicle-inductive properties for hair replacement therapy.

In this study, riboflavin deficiency symptoms were observed in Guernsey calves fed radiated milk, but adding riboflavin improved growth and health, indicating its essential dietary need for young calves.

In this case report, the successful treatment of iodine deficiency in a one-month-old female buffalo calf with alopecia was described, highlighting the importance of early diagnosis and management to ensure proper growth and development.

Foam sclerotherapy for varicose veins may cause unexpected hair growth.

This study found that selecting Angus cattle for early puberty reduced their prolactin levels, which may indicate a response to changing day length.

This study found that angiogenin is expressed in human dermal papilla cells, where it might stimulate hair growth by promoting cell proliferation and local skin angiogenesis.

In this study, zinc supplementation at 2.00 g/camel/day improved hair growth in lactating camels but did not affect milk production, while for calves, doses of 0.50–0.75 g/camel/day enhanced growth and hair development.

This article reviews the mechanisms by which minoxidil stimulates hair growth and reports no new clinical findings.

This study found that minoxidil significantly increases VEGF mRNA and protein expression in dermal papilla cells, suggesting a role in enhancing hair follicle vascularization in androgenetic alopecia.

This study suggests that minoxidil activates PGHS-1, which may explain its hair growth-stimulating effects and could aid in designing more potent hair growth-promoting drugs.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

In this study, researchers reported that a keratinocyte growth factor-Ig fusion protein could specifically detect and localize KGFRs in epithelial tissues, suggesting a method for histochemical detection of growth factor receptors.

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study found that hydroxysafflor yellow A-rich Carthamus tinctorius extract promoted hair growth and gene expression linked to hair proliferation in both cell cultures and mouse models.

This study found that Ecklonia cava enzymatic extract, particularly its component dieckol, promoted hair growth by increasing dermal papilla cell proliferation and inhibiting 5α-reductase activity in cultured vibrissa follicles and C57BL/6 mice.

This study found that minoxidil did not significantly increase hair shaft elongation in ex vivo human hair follicle culture, questioning the suitability of this method for studying its hair-growth-promoting effects.

Eating isoflavone can help mice grow hair by increasing a growth factor.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This study found that Undariopsis peterseniana extract may promote hair growth by activating specific cellular pathways, suggesting potential for treating alopecia.

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.

This article reviews the proposed mechanism of minoxidil in treating androgenetic alopecia, suggesting it may prolong the anagen phase by modulating cell growth factors and vascular activity, but reports no new results.

This study suggests that a mixture of 5‐ALA and iron ion significantly improved hair growth in mice, comparable to minoxidil, without promoting keratinocyte or fibroblast proliferation in vitro.

This study demonstrated that safflower seeds can be engineered to express oleosin-FGF10, which showed a dose-dependent effect on cellular proliferation, potentially facilitating scalable protein production.

Acankoreoside J from Acanthopanax koreanum may help promote hair growth.
