research The Circular RNA CircCOL1A1 Functions as a miR-149-5p Sponge to Regulate the Formation of Superior-Quality Brush Hair via the CMTM3/AR Axis
A specific RNA molecule, circCOL1A1, affects the growth and quality of goat hair by interacting with miR-149-5p and influencing cell growth pathways.
research Mineral requirements of hair sheep in tropical climates
Hair sheep in tropical climates need different mineral amounts for growth than commonly recommended.
research The germinative epithelium of sheep vibrissae and wool follicles has extensive proliferative potential but is dependent on the dermal papilla
Sheep hair follicle cells can grow a lot but need the dermal papilla to do so.
research Exogen, Shedding Phase of the Hair Growth Cycle: Characterization of a Mouse Model
Researchers found that hair shedding happens mostly when new hair is growing and involves a unique process.

Melatonin treatment increases wool production and improves fiber quality in angora rabbits.
research Hair
Hair grows from living roots, is made of dead keratin, and goes through growth, rest, and shedding stages.
research Transforming growth factor-alpha immunoreactivity during induced hair follicle growth cycles in sheep and ferrets.
TGF-alpha is present in sheep and ferret skin and may affect hair growth without directly stimulating cell proliferation.
research Modeling the dynamics of human hair cycles by a follicular automaton
The model successfully simulates human hair growth and patterns, including hair loss types.
research Improving stable isotopic interpretations made from human hair through reduction of growth cycle error

research EEMCO Guidance for the Assessment of Hair Shedding and Alopecia
The document explains hair growth and shedding, factors affecting it, and methods to evaluate hair loss, emphasizing the importance of skin biopsy for diagnosis.
research The Morphological Basis of vicuña wool: Skin and gland structure in Vicugna vicugna (Molina 1782)
Vicuña wool's quality is due to a high density of fine secondary hair follicles, and their skin glands may be used for communication.
research Association analysis of polymorphisms in six keratin genes with wool traits in sheep
Certain gene mutations are linked to wool quality in sheep and could help in breeding for better wool.
research The transcriptional landscape of seasonal coat colour moult in the snowshoe hare
Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.
research The frictional properties of wool and related hair fibers.
research [Regulation of hair follicle cycle].
Hair growth is controlled by cycles influenced by hormones and various signals.
research Continuous Dynamics of The Hair Follicle: Spiral Model for Understanding Follicular Activity Throughout Life
The Spiral Model helps understand hair growth changes with age and identify hair problems early.
research Characterization of dermal type I collagen of C3H mouse at different stages of the hair cycle
Collagen remodeling is more active during hair growth stages.
research Reflectance spectroscopy for noninvasive evaluation of hair follicle stage
Reflectance spectroscopy can noninvasively track hair growth stages by measuring skin reflectance and melanin changes.
