Older people's sweat glands are less effective at helping skin wounds heal due to weaker cell connections.

Chronic scalp pain in trichodynia involves both body-wide and localized increased pain sensitivity.

Sex hormones, especially estradiol, can change chicken feather shapes and colors.

Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.

Using an enzyme and keratin treatment can significantly repair and strengthen damaged hair.

Sebaceous glands can heal and regenerate after injury using their own stem cells and help from hair follicle cells.

Mothers have more hair proteins than their children, with age-related differences in protein patterns, and some proteins in hair could indicate early childhood development.

Researchers found that certain RNA sequences play a role in yak hair growth and these sequences are somewhat similar to those in cashmere goats.

PlacMA hydrogels from human placenta are versatile and useful for cell culture and tissue engineering.

The document is a detailed medical reference on skin and genetic disorders.

Alopecia Areata causes significant structural and compositional changes in hair.

Nanofiber scaffolds help wounds heal by delivering drugs directly to the injury site.

Tongue cancer cells show more plectin-1 than non-cancer cells, but both have similar levels of trichohyalin.

Different hair follicles in the skin are innervated by unique combinations of mechanosensory neurons, crucial for touch sensation.

Kangfuxin (KFX) extract speeds up wound healing and improves skin regeneration.

Metabolic signals and cell shape influence how cells develop and change.

Enzymes called PADIs play a key role in hair growth and loss.

Understanding keratinization is crucial for treating skin conditions like ichthyoses and psoriasis.

Hair loss, known as Androgenetic Alopecia, is often caused by hormones and can be diagnosed using noninvasive techniques. Treatments include topical minoxidil and oral finasteride, with new treatments being explored. There may also be a link between this type of hair loss and heart disease risk.

Vitamin D receptor is crucial for skin wound healing.

Hair proteins in preschool children and their mothers could indicate developmental changes and health status.

The study concluded that the new wound model can be used to evaluate skin regeneration and nerve growth.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

The document concludes that recent research has improved understanding of skin diseases and the balance between cell growth and differentiation in the epidermis.

Epidermolytic ichthyosis can be inherited in a semidominant way with mild symptoms in carriers.

Intermediate filaments are crucial for cell structure and function, regulated by specific genes and proteins.

Curved human hair has different structures on its convex and concave sides.

Different conditions affect how hair proteins assemble, and certain mutations can change their structure.

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