Bioassays help find useful compounds in nature for making medicines, supplements, and cosmetics.

Androgens and androgen receptors are important for metabolic health, affecting how the body uses glucose and fats through mitochondrial function.

Polycystic ovary syndrome and iron overload share similar symptoms and can be potentially treated with blood removal, diet changes, and probiotics.

The hair of two ancient Chilean mummies is well-preserved and contains high levels of heavy metals.

Disulfide bonds are crucial for hair's strength, especially when wet.

Keratin peptides can change hair shape gently without harsh chemicals.

Hair conditioners with argan oil or camellia oil improve the strength and color of bleached hair.

Hair follicle stem cells from Arbas Cashmere goats can become fat, nerve, and liver cells.

Using stem cells from fat tissue can significantly improve wound healing in dogs.

Genetic factors affect hair loss, and molecular testing may help predict, diagnose, and treat it.

Bleaching hair causes severe structural and chemical damage, including protein loss and oxidation.

Inhibiting Zyxin may help treat androgenetic alopecia by promoting hair growth.

Double-stranded RNA helps regenerate hair follicles by increasing retinoic acid production and signaling.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

Male and female human hairs have different microscopic structures that can help in forensic analysis.

Pica disorder in central Iraq is mainly found in females and is linked to low iron levels; treatment with iron improves most patients.

The model suggests that scalp tension could lead to hair loss, with factors like blood vessel hardening, enlarged oil glands, and poor microcirculation also playing a role. It also hints at a possible link between skull shape and baldness pattern.

Peptides from oysters may safely and effectively heal skin wounds with less scarring.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

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.

Stuff from umbilical cord stem cells helps skin heal and look younger.

HSPGs help control stem cell behavior, affecting hair growth and offering a target for hair loss treatments.

Rex rabbits' hair follicles develop dynamically in the first 8 weeks, with key genes and proteins changing over time.

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

Antiviral drugs, especially daclatasvir, may be a new treatment for a rare skin disease, improving survival and reducing symptoms in mice.

The secretome from mesenchymal stromal cells shows promise for improving facial nerve injury treatment.

The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.

The spiny mouse can regenerate its skin without scarring, which could help us learn how to heal human skin better.

Mesenchymal stem cells could help treat aging-related diseases better than current methods.
