Different treatments change the strength and flexibility of human hair.

The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.

Mammalian hair scales change from smooth to wavy due to friction.

Age-related hair curvature increases due to internal structural changes from grooming.

Warming hands improves blood flow in people with systemic sclerosis.

The model showed that randomness accurately describes individual hair growth cycles and that synchronization can cause large fluctuations not seen in humans.

Circadian rhythms are crucial for stem cell function and tissue repair, and understanding them may improve aging and regeneration treatments.

The study found that the Marangoni effect causes the uneven wetting of surfactant-coated hair due to the surfactant moving into the water.

Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.

The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

New method uses hair follicle cells to estimate human body clock phase, potentially improving sleep disorder diagnosis.

The curved nonrotary punch is better for hair extraction in people with tightly curled hair.

Both punch types are effective, but they differ in transection rates and ease of use.

Cells communicate with neighbors to coordinate their development.

The document concludes that understanding hair follicle biology can lead to better hair loss treatments.

Hormonal changes after childbirth and menopause can lead to women's hair loss and facial hair growth, with a need for better treatments.

Researchers developed a way to study human body clocks using hair tissue, which works similarly in both healthy and dementia patients.

Bright light during the day doesn't change most human clock genes but may slightly increase Rev-erb-ß.

Sleep problems and skin issues affect each other; poor sleep can worsen skin conditions, and some skin treatments can improve or harm sleep quality.

Curly and straight hair differ in how their internal fibers are arranged.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

Vitamin D receptor interacts with certain dietary components to help prevent diseases and regulate hair growth.

The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.

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.

4D polycarbonate scaffolds show promise for soft tissue repair due to their biocompatibility, shape memory, and minimal immune response.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

MDP hydrogel heals wounds faster and better than other treatments in diabetic mice.

Changes to the Foxp3 protein affect how well regulatory T cells can control the immune system, which could help treat immune diseases and cancer.

Coats' Plus is a genetic disorder with eye abnormalities, brain calcification, poor growth, bone and skin issues, and movement disorders.
