Human hair is made up of different keratins, some strong and some weak, with specific types appearing at various stages of hair growth.

A rabbit gene important for hair development was identified and detailed.

Keratoacanthomas and squamous cell carcinomas have similar keratin patterns, making them hard to tell apart.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

Keratin structure changes during keratinization, but the exact model remains uncertain.

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

Mutations in specific keratin genes cause improper hair structure in mice due to faulty keratin protein assembly.

Keratin gene clusters in humans and marsupials are similarly organized.

Different treatments for Hidradenitis suppurativa range from antibiotics and hormonal therapies to surgery, depending on severity.

Telogen is an active phase with important biological processes, not a resting phase.

Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.

Human hair was used to make biodegradable plastic films that could be useful for packaging and disposable products.

Keratin proteins are increasingly recognized as important for cell health and are linked to many diseases.

Alkylation of human hair keratin allows for adjustable drug release rates in hydrogels for medical use.

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

New nanofiber technology improves wound healing by supporting cell growth and delivering treatments directly to the wound.

Hair follicle regeneration possible, more research needed.

Scientists created a long-lasting stem cell line from human hair that can turn into different skin and hair cell types.

The review found that different stem cell types in the skin are crucial for repair and could help treat skin diseases and cancer.

Topical minoxidil helps treat female pattern hair loss, but more research needed for other treatments.

FoxN1 gene is essential for proper thymus structure and preventing hair loss.

The study found stem cells in minor salivary glands that can differentiate and are involved in tumor formation when exposed to tobacco.

The study found genetic differences related to hair development that may explain hair loss in a patient with Trichorhinophalangeal syndrome type I.

ODC overexpression in hair cells increases tumor growth by reducing Notch signaling.

Genes related to keratin, skin cell differentiation, and immune functions are key in hedgehog skin and spine development.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Disrupting Smad4 in mouse skin causes early hair follicle stem cell activity that leads to their eventual depletion.

Changes in keratin make hair follicles stiffer.

Exosomes show promise for improving wound healing, reducing aging signs, preventing hair loss, and lightening skin but require more research and better production methods.

Bone marrow stem cells and their medium help hair regrowth.
