Mutations in the PADI3 gene are linked to a higher risk of scarring hair loss in women of African descent.

A 2-year-old girl had a hair disorder not shared by her identical twin.

The genes KRT25 and SP6 affect curly hair in horses, with KRT25 also causing hair loss. If both genes are mutated, the horse gets curly hair and hair loss. KRT25 can hide the effect of SP6.

Scanning electron microscopy revealed four distinct hair root shapes in alopecia areata, suggesting a less invasive diagnostic method.

A young boy with a rare skin and nail condition improved significantly with simple topical treatments.

A thorough history and examination are crucial for diagnosing skin diseases, which affect up to a third of people. This includes details about skin lesions, medication, general health, lifestyle, family, and contacts, as well as examining the rash, hair, nails, and mucous membranes. Changes in hair and nails can also indicate other medical and skin disorders.

Nanotechnology is improving drug delivery and targeting, with promising applications in cancer treatment, gene therapy, and cosmetics, but challenges remain in ensuring precise delivery and safety.

The document provides advice on how to recognize and treat skin-related side effects of cancer drugs known as EGFR inhibitors.

Doctors should use a detailed patient history and physical exam to diagnose joint pain, and consult a rheumatologist early for suspected autoimmune diseases.

Using longer PEG chains helps nanoparticles penetrate hair follicles better, improving drug delivery for conditions like alopecia.

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

Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.

The cell membrane complex in mammalian hair has three distinct types with different structures and chemical properties.

The torsional method effectively evaluates hair damage and the performance of hair care ingredients.

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

The cuticle significantly contributes to hair stiffness, making up about 60% of the total bending stress.

Teratoma hair is similar to scalp hair but has a rougher surface and lower adhesive force.

Human hair's strength and flexibility vary by ethnicity, damage, and treatment.

Eyelash curvature is linked to the thickness of the cuticle layer at the root.

Hair dye can damage dog hair and cause health issues.

Polymethylene wax in hair relaxers makes hair smooth and shiny with less damage.

Hair damage increases significantly with higher temperatures and longer heating times.

Frequent blow-drying causes cracks and breakage in hair cuticles.

Human hair absorbs calcium and magnesium from tap water, affecting its structure and styling properties.

A 6-year-old girl's inability to grow her hair long was due to Loose Anagen Hair Syndrome, which causes hair to shed easily and may improve with age.

X-ray microscopy can non-invasively show hair structure changes after treatments, but it's less detailed than TEM and needs improvement.

The hair's outermost surface has multiple layers of lipids and proteins.

TGase 3 helps build hair structure by forming strong bonds between proteins.

Oxidation changes human hair by breaking down fats and forming new acidic groups, affecting how it interacts with conditioners and cosmetics.

The study found nine new hair protein genes in human hair follicles.
