The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.

Microfibrils are key for permanent waves, and hydrolyzed keratin improves wave formation and hair condition.

Hair follicle cells become four types: medulla, cortex, cuticle, and inner root sheath.

Drosha and Dicer are essential for hair follicle health and preventing DNA damage in skin cells.

The research identified genes that explain why some sheep have curly wool and others have straight wool.

Infrared radiation can cause skin aging and cancer at high temperatures but may have therapeutic benefits at controlled levels.

The method successfully isolates cells that are important for hair growth and could help study hair loss.

Minoxidil affects collagen-related genes, potentially helping treat fibrosis.

Scientists now better understand how human hair growth is controlled, including the roles of specific genes and proteins.

Keratin fibrils in hair form and stop growing at specific points in the follicle.

Erythropoietin helps hair grow and could be a potential treatment for hair loss.

A patch made from human lung fibroblast material helps heal skin wounds effectively, including diabetic ulcers.

The Ovol2-Zeb1 circuit is crucial for skin healing and hair growth by guiding cell movement and growth.

Menopause reduces skin collagen and elasticity, and while estrogen therapy can help, its risks require careful consideration.

Hair follicles can regenerate after radiation damage but not during a specific growth phase.

Early-stage skin cells help regenerate hair follicles, with proteins SDF1, MMP3, biglycan, and LTBP1 playing key roles.

Method detects finasteride in plasma at very low concentrations.

Vitexin Compound 1 may help reduce skin aging caused by UVA light.

Anti-acne medications may work by reducing the activity of a protein involved in acne development.

The basement membrane matrix helps rebuild hair follicles faster and more effectively.

Scientists made a mouse that shows how a specific protein in the skin changes and affects hair growth and shape.

Platelet-rich plasma (PRP) may help promote hair growth and improve graft survival after hair transplantation, but more research is needed to confirm its effectiveness and determine the best dosage.

Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.

Scalp cooling is the most effective FDA-approved method to prevent chemotherapy-induced hair loss, but more research is needed for other treatments.

The article suggests that targeting specific immune pathways could help control and treat the skin disease hidradenitis suppurativa.

Genes linked to fibrosis are more active in people with central centrifugal cicatricial alopecia.

IL-9 increases skin cell movement but decreases their ability to invade, and this effect is controlled by cell contractility, not by MMPs.

Tranexamic acid reduces skin aging more in female mice.

Aging causes sweat glands to shrink and move upward, leading to less elastic skin and more wrinkles.
