Grape seed oil improved hair quality the most, followed by rosehip and safflower seed oils, and reduced damage from shampoo.

The new hydrogel helps heal burn wounds better than current options by reducing bacteria and inflammation.

Peptide hydrogels show promise for healing skin, bone, and nerves but need improvement in stability and compatibility.

Two rare genetic diseases cause severe rickets in children due to defects in vitamin D metabolism.

Hair from breast cancer patients shows changes in structure and composition, and a test using these changes detected cancer but also falsely identified some healthy samples as cancerous.

The extracellular matrix is crucial for controlling skin stem cell behavior and health.

Stem cell offspring help control their parent stem cells, affecting tissue health, healing, and cancer.

Advanced hydrogel systems with therapeutic agents could greatly improve acute and chronic wound treatment.

Cornification is the process where living skin cells die to create a protective barrier, and problems with it can cause skin diseases.

The skin's basement membrane is specially designed to support different types of connections between skin layers and hair follicles.

Peptide hydrogels heal burn wounds faster and better than standard dressings.

Different ectodermal organs like hair and feathers regenerate differently, with specific stem cells and signals involved in their growth and response to the environment.

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

3D bioprinting in plastic surgery could lead to personalized grafts and fewer complications.

Human hair keratins can be turned into useful 3D biomedical scaffolds through a freeze-thaw process.

Keratin-based particles safely improve hair strength, smoothness, and heat protection.

The flap assay grows the most natural hair but takes the longest, the chamber assay is hard work but gives dense, normal hair, and the patch assay is quick but creates poorly oriented hair with some issues.

Men's age, urinary symptoms, and heart health risks create different types of erectile dysfunction.

The study concludes that certain domains in Clostridium histolyticum enzymes are structurally unique, bind calcium to become more stable, and play distinct roles in breaking down collagen, with potential applications in medicine and drug delivery.

The conclusion is that using light-sheet fluorescence microscopy with a special solution can effectively create detailed 3D images of human skin for dermatological research.

Human hair has different protein structures in its cuticle and cortex.

Scientists created three types of structures to help regrow hair follicles, and all showed promising results for hair regeneration.

UVB radiation changes the chemical makeup and dries out human hair but doesn't alter its appearance or texture.

3D imaging of skin biopsies offers better accuracy but is time-consuming and can't clear melanin.

The conclusion is that tissue structure is key for stem cell communication and maintaining healthy tissues.

Mutations in the enzyme don't significantly change how it binds to its specific substances.

Cystatin M/E strongly inhibits cathepsin V and cathepsin L, important for skin formation.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.

Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
