Adding human hair to clayey soil makes it stronger, even after freeze-thaw cycles, and is eco-friendly and cheap.

Chemical hair straightening improves smoothness and shine but may cause side effects, suggesting a need for safer methods.

Researchers extracted tiny keratin filaments from human hair by unzipping its outer layer.

Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.

Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.

Yak belly hair has higher porosity and is less stiff than human hair, making it absorb dye better but less suitable as a direct substitute for hair dyeing.

Scientists created a colored thread-like material containing a common hair loss treatment, which slowly releases the treatment over time, potentially offering an effective, neat, and visually appealing solution for hair loss.

Heat transfer in hair is slower in groups of hair, increasing the risk of damage from high-temperature styling tools.

A new method accurately measures amino acids in treated hair, showing bleaching reduces amino acids while protein treatments increase them.

Animal models, especially mice, are essential for advancing hair loss research and treatment.

New scaffold materials help heal severe skin wounds and improve skin regeneration.

Future research should focus on making bioengineered skin that completely restores all skin functions.

Keratin 18 helps diagnose and predict cancer progression and affects cancer growth and spread.

Homeopathic treatments can effectively manage hair loss and improve well-being.

Innovative methods are reducing animal testing and improving biomedical research.

Microneedle technology is effective for skin rejuvenation and enhancing cosmeceutical delivery, with ongoing innovation and increasing commercialization.

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

The document suggests a bacteria plays a significant role in acne rosacea and that white hair can regain color after transplant, meriting more research on reversing grey hair.

Hair transplant is effective for treating hair loss caused by radiation and improves patients' quality of life.

Understanding phenotypic plasticity is crucial for developing effective cancer therapies.

Artificial skin development has challenges, but new materials and understanding cell behavior could improve tissue repair. Also, certain growth factors and hydrogel technology show promise for advanced skin replacement therapies.

Microneedles help improve skin appearance and deliver skin treatments effectively, but safety concerns need more research and regulation.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.

MDP hydrogel heals wounds faster and better than other treatments in diabetic mice.

Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.

We don't fully understand how sunlight damages different types of hair.

Keratins are important for skin cell health and their problems can cause diseases.

Advancements in creating skin grafts with biomaterials and stem cells are promising, but more research is needed for clinical application.

Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
