A specific type of skin cell creates an opening for hair to grow out, and problems with this process can lead to skin conditions.

The document concludes that hair follicles have a complex environment and our understanding of it is growing, but there are limitations when applying animal study findings to humans.

Keratin protein production in cells is controlled by a complex system that changes with cell type, health, and conditions like injury or cancer.

Hair health depends on various factors and hair loss can significantly affect a person's well-being; understanding hair biology is key for creating effective hair care treatments.

The document concludes that while some organisms can regenerate body parts, mammals generally cannot, and cancer progression is complex, involving mutations rather than a strict stem cell hierarchy.

The document explains how hair follicles develop, their structure, and how they grow.

Any drug can cause skin reactions, but antibiotics, NSAIDs, and psychotropic drugs are more common, with some reactions being life-threatening.

The study found a link between the severity of Lichen Planopilaris seen by doctors and the details seen under a microscope, and created a new way to measure this severity.

Different small areas within hair follicles send specific signals that control what type of cells stem cells become.

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

Follistatin and LIN28B together improve the ability of inner ear cells in mice to regenerate into hearing cells.

Quercetin significantly helps hair growth by activating hair follicles and improving blood vessel formation around them.

Basal cell carcinomas may differentiate similarly to hair follicles and could be influenced by hair cycle-related treatments.

Removing Mediator 1 from certain mouse cells causes teeth to grow hair instead of enamel.

Different stem cells are key for hair growth and health, and understanding their regulation could help treat hair loss.

Somatostatin may help protect hair follicles from immune attacks.

Mesenchymal stem cell therapy may help treat alopecia areata by promoting hair growth and reducing inflammation.

The research identified genes that explain why some sheep have curly wool and others have straight wool.

Dihydrotestosterone (DHT) mainly affects nearby cells, doesn't significantly change prostate hormonal environment or cancer risk, and doesn't play a main role in causing hair loss or acne. More research is needed on its effects on heart health, sexual function, and bone health.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

Human beard hair medulla contains a unique and complex mix of keratins not found in other human tissues.

Creating stronger blockers for skin enzymes might lead to better treatment for conditions like acne and excessive hair growth.

Male hormones and their receptors play a key role in hair loss and skin health, with potential new treatments being explored.

Regenerative pharmacology, which combines drugs with regenerative medicine, shows promise for repairing damaged body parts and needs more interdisciplinary research.

Botulinum toxin has potential for treating various skin conditions and improving wound healing.

Scalp cooling can help prevent chemotherapy-induced hair loss with a 50-90% success rate and is safe for patients.

Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Eating collagen peptides may help with skin and hair growth.

People with pemphigus vulgaris and pemphigus foliaceus often have smaller sebaceous glands on their scalp.

CIP/KIP proteins help stop cell division and support hair growth.
