Melatonin implants can change the seasonal prolactin levels and hair growth in adult cashmere goats but not in juveniles, and don't delay spring moult for better fiber harvesting.

Adult male raccoon dogs shed their winter fur in spring and grow new fur for winter in autumn.

Prolactin speeds up hair growth and moulting in cashmere goats.

Animals that change color with the seasons mainly do so in response to daylight changes, but climate change is causing camouflage problems that may require evolutionary changes.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.

Researchers found genes that control hair color and growth change before the visible coat color changes in snowshoe hares.

Melatonin implants and long daylight hours alter the timing of hormone release and hair growth in mouflon sheep.

Melatonin treatment speeds up fur maturation and changes the hair growth cycle in young chinchillas.

Hormones and daylight changes control when cashmere goats shed their hair.

Mouflon rams mature gradually with changes in body, horns, and hormones linked to age and seasons, reaching full sexual maturity well after puberty.

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

Androgens can cause hair growth in some areas and hair loss on the scalp.

Mice hair growth patterns get more complex with age and can change with events like pregnancy or injury.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

Prolactin affects hair growth cycles and can cause early hair follicle regression.

Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.

The woman's hair loss was mainly due to stress and low iron levels, and her hair grew back after treatment.

The guide helps clinicians diagnose and manage hair loss, detailing examination techniques and treatments for different types of alopecia.

Goat reproductive activity and coat growth are affected by light and temperature, with temperature altering prolactin levels and hair growth, but not melatonin or estrus onset.

Androgens can both increase and decrease hair growth in different parts of the body.

Androgens can both stimulate and cause hair loss, and understanding their effects is key to treating hair disorders.

Hair growth is influenced by hormones and goes through different phases; androgens can both promote and inhibit hair growth depending on the body area.

Genes related to pigmentation, body rhythms, and behavior change during hares' seasonal coat color transition, with a common genetic mechanism in two hare species.

Melatonin treatment may increase cashmere production in Spanish goats.

Goat hair growth and follicle activity change with the seasons and differ between males and females.

The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.

Alopecia in captive rhesus macaques is affected by season, sex, age, housing, and stress, with complex links between stress hormones and hair loss.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.
