Too much Smad7 changes skin and hair development by breaking down a protein called β-catenin, leading to more oil glands and fewer hair follicles.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

Postpartum depression is linked to changes in brain chemicals, inflammation, stress, and certain genes, and can potentially be identified by markers like specific steroids, serotonin levels, and vitamin D levels.

Hair follicles may soon be used more for targeted and systemic drug delivery.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

The niche environment controls stem cell behavior and plasticity, which is important for tissue health and repair.

Modern science supports the use of some Ayurvedic plants for health, as ancient practices suggested.

K6hf is a unique protein found only in a specific layer of hair follicles.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

Matriptase is crucial for keeping epithelial tissues healthy and functioning properly.

The HR protein helps hair grow by blocking a hair growth inhibitor, aiding in hair follicle regeneration.

Horizontally sectioned scalp biopsies are more reliable for diagnosing hair loss in women when three samples are taken instead of one.

The document recommends using both clinical evaluation and various measurement methods to assess skin greasiness, considering factors like temperature and hormones.

Finasteride effectively blocks enzyme causing male pattern baldness.

Different types of stem cells and their environments are key to skin repair and maintenance.

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

Forehead modification greatly increases the perception of femininity and is a safe procedure.

Nanoparticles can improve skin drug delivery but have challenges like toxicity and stability that need more research.

Silver nanoparticles coated with substances like PEG showed strong antibacterial effects and improved wound healing when used in hydrogels.

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.

Early detection and intensive treatment of diseases caused by Staphylococcus aureus toxins are crucial for reducing severe health effects.

Foxp3 is crucial for regulatory T cell function, and targeting these cells may help treat immune disorders.

Substances from Chinese medicines show promise for immune support and disease prevention, but the way they are processed affects their effectiveness.

Fat cells in the skin help start healing and form important repair cells after injury.

Male hormones like testosterone may make COVID-19 worse, and testing for sensitivity to these hormones could help predict how severe a patient's symptoms might be. Treatments that reduce these hormones are being explored.

Terbinafine quickly builds up in skin and hair, staying effective for over 3 weeks.

Minoxidil can help grow hair in mice by making cells grow and improving hair quality. More research needed.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.

Exposure to finasteride in the womb caused lasting reproductive issues in male rats.
