Hair quality is genetically determined and linked to its composition and strength.

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

Disulfide bonds in keratin fibers break more easily under stress, especially when wet, affecting fiber strength.

Minoxidil-loaded NLC gel shows potential for effective alopecia treatment.

Male faces age with more wrinkles and hair loss, influenced by both body changes and environmental factors.

Hair follicle stem cells help maintain skin health and could improve skin replacement therapies.

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.

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

Different fibroblasts play key roles in skin healing and scarring.

New signs like changes in blood markers, physical symptoms, and behavioral shifts may help detect hidden steroid use in athletes.

Scientists found a specific group of itch-sensing nerve cells in mice important for feeling itch but not for sensing heat or touch.

Hair transplantation is highly effective with careful technique and attention to patient needs.

Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.

Skin may help in getting rid of excess iron through the process of skin cell renewal.

The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.

Keratin hydrogel from human hair is a promising biocompatible material for soft tissue fillers.

Keratin from human hair shows promise for medical uses like wound healing and tissue engineering.

Testosterone is important for men's sexual function, may help some women's sexual desire, while other hormones and neurotransmitters also play complex roles in sexual behavior.

Shampoo B, which uses water-soluble silicone, is better at detangling hair in wet conditions due to its two-layer conditioning film.

Asiasari radix extract may relieve certain types of pain by affecting GABA and NMDA receptors.

Redheaded people have higher levels of a vitamin D precursor, suggesting red hair may be an adaptation for better vitamin D synthesis in areas with less sunlight.

Different nail disorders are treated by targeting their specific causes and using appropriate medications or protective measures.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Bariatric surgery may help severely obese teenagers but has risks and requires careful patient selection and long-term care.

Proper care and diet are crucial to prevent health issues in gerbils.

Keratin from hair and wool is used in medical materials for healing and drug delivery.

The study created a tool that mimics natural cell signals, which increased cell growth and could help with hair regeneration research.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Electrospun matrices help regenerate skin and hair follicles using PCL and collagen scaffolds.

Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
