The timing of when the gene Bmal1 is active affects aging and survival, with its absence during development, not adulthood, leading to premature aging.

The skin's ability to produce hormones is linked to various skin conditions, and better understanding this process could lead to new treatments.

Male hormones indirectly affect skin cell development by increasing growth factor levels from skin fibroblasts.

ILK and ELMO2 help cells move and stick together, important for wound healing and hair growth.

Feather patterns are influenced by enhancers and chromatin looping, and the structure of protein complexes important for hair growth has been detailed.

Premature graying of hair is often linked with other health issues, but treatment with biotin, zinc, and calcium pantothenate is not very effective.

Activins and follistatins, part of the TGFβ family, are crucial for hair follicle development and skin health, affecting growth, repair, and the hair cycle.

Gray hair is caused by oxidative stress damaging hair cells.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

Pmg-1 and Pmg-2 are new genes important for skin and mammary gland development.

Salvia plebeia extract can stimulate hair growth.

An apple-based supplement was found to stimulate hair protein production, which may help with hair growth.

The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.

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

A specific mutation in the K25 gene causes a rare genetic disorder with curly hair at birth and later hair loss, along with dental issues.

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

Inflammation around hair follicles leads to hair loss, and treatments should focus on reducing this inflammation and other factors for effectiveness.

Certain treatments can increase protein binding to natural hair but are less effective on permed hair.

Cell polarity signaling controls tissue mechanics and cell fate, with complex interactions and varying pathways across species.

Proteomics combined with other technologies can lead to a better understanding of skin diseases.

Bleaching hair changes its structure and weakens it, which is important for understanding hair damage and creating treatments.

Most over-the-counter hair loss treatments lack strong evidence of effectiveness and are not FDA-approved.
