Short photoperiods improve cashmere growth and quality in goats by changing hormone levels and gene expression.

Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

Trichohyalin, a hair follicle protein, has a part with repeating patterns of 23 amino acids.

Lambs fed a liquid diet showed abnormal wool and skin, which improved with more B-vitamins, suggesting a link to B-vitamin deficiency.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Hair and wool have complex microscopic structures with microfibrils and varying cystine content.

Hair growth can be induced by certain cells found at the base of hair follicles, and these cells may also influence hair development and regeneration.

IL-36α helps grow new hair follicles and speeds up wound healing.

Mice can grow new hair follicles after skin wounds through a process not involving existing hair stem cells, but requiring more research to understand fully.

Scientists created a model using sheep cells to study hair root formation, which can test how different substances affect hair growth.

Estrogens significantly influence hair growth by interacting with receptors in hair follicles and may help regulate the hair growth cycle.

Finasteride helps hair growth by decreasing cell death in hair follicles.

Genes affecting wool fiber thickness in Angora rabbits were identified, which could help breed finer wool.

Key genes regulate hair follicle phase changes in Inner Mongolia cashmere goats.

Giving selenium yeast to pregnant goats leads to better hair growth and cashmere quality in their babies.

Melatonin improves cashmere goat hair growth and quality by increasing antioxidants and reducing cell death.

Researchers created a lab model to study human hair growth, showing it can grow and self-regulate outside the body.

New hair can grow from large wounds in mice, but less so as they age, involving reprogramming of skin cells and specific molecular pathways.

The research shows that a gene called Wnt3 affects hair growth and structure, causing short hair and balding when overactive.

Prolactin may affect hair growth differently based on gender and scalp area.

Minoxidil affects cell growth in two ways: low doses increase growth, while high doses slow it down and can be toxic.

Minoxidil was first made for high blood pressure, but it was later found to help hair growth.

Different cell types work together to repair skin, and targeting them may improve healing and reduce scarring.

Using gelatin sponges for deep skin wounds helps bone marrow cells repair tissue without scarring.

Key genes and RNAs related to hair growth in sheep were identified, aiding future breeding improvements.

Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.

Certain genes related to sulfur metabolism are more active during the growth phase of Cashmere goat wool, and melatonin might help this process.

CAP1 decreases the expression of a hair-related protein in young Tan sheep's skin.

CRISPR/Cas9 gene-editing shows promise for improving sheep and goat breeding but faces challenges with efficiency and accuracy.

Improving knowledge and practices in animal fibre production is crucial to meet market demands and potentially revive natural fibres.
