Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.

Most women in the study lost hair due to chronic shedding, with stress and nutrient deficiencies being common factors.

SARS-CoV-2, the virus causing COVID-19, can affect all endocrine organs and systems, altering their function and potentially leading to disorders. Factors like diabetes and obesity increase infection risk and severity. Understanding these effects is key for effective treatment.

Dermatologists give better information on pathology forms, hypersensitivity vasculitis is a common skin issue, misdiagnoses can occur, and various skin conditions are linked to loss of elastin or genetic factors.

Emotional factors are crucial in treating and preventing scalp neurodermatitis and hair loss.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.
