Hair transplantation surgery has improved, giving more natural results, and success depends on a skilled team and proper technique.

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

New cell-based therapies may improve hair loss treatments in the future.

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

Stress can slow hair growth and affect skin color by impacting the body's stress response system.

Hair transplant improves with regenerative medicine and FUE technique.

Most dogs have hair whorls on their chest and limbs, with shelter dogs and short-haired dogs having more chest whorls.

AI is effective in diagnosing and treating hair disorders, including detecting hair loss and scalp conditions with high accuracy, but it should supplement, not replace, doctor-patient interactions.

3D bioprinting with special hydrogels can create artificial skin that heals wounds and regrows hair in mice.

Muskox hair growth rates vary widely, so a single growth rate can't be used for all populations.

Best hair transplant results happen when tissues are least damaged.

Calcium affects where root hairs grow, but other unknown factors determine their growth direction.

Researchers found 19 genes important for root hair growth in a plant called Arabidopsis.

Researchers developed a new model for more realistic computer graphics rendering of hair by considering how light scatters on hair fibers.

Mutant CDP/Cux protein causes hair defects and reduced male fertility in mice.

Researchers developed a new model for more realistic computer graphics of hair by considering how light scatters on hair fibers.

Cell division orientation varies by body site and is linked to epidermal thickness and cell density.

Stem cell therapy could help regenerate inner ear hair cells to treat hearing loss.

TGF-alpha is present in sheep and ferret skin and may affect hair growth without directly stimulating cell proliferation.

Surgical hair restoration involves moving hair from a non-balding area to a balding area, with the transplanted hair not subject to male pattern baldness. Medications can slow hair loss and regrow some hair, but successful treatment needs careful planning, skill, and ethical responsibility due to progressive hair loss and limited donor hair.

COVID-19 can cause different types of hair loss, with telogen effluvium being the most common.

Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.

Activating Nrf2 helps wounds heal faster by increasing hair follicle stem cells.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

Stress increases a factor in mice that leads to hair loss, and blocking this factor may prevent it.

Chemical treatments can change the scale heights of wool and cashmere fibers, affecting their identification.

ALA-PDT is effective and safe for chronic X-ray dermatitis, providing complete or partial remission.

Human hair keratins can self-assemble and support cell growth, useful for biomedical applications.

Ancient hair can preserve hormones, revealing health and fertility insights.

AGD1 is important for root hair development in Arabidopsis, working with phosphoinositide signaling and the actin cytoskeleton.
