Chemotherapy and radiation therapy cause skin and hair damage by altering gene expression and signaling pathways.

Early and late matrix progenitors in hair follicles create different cell layers, with early ones forming the companion layer and later ones forming the inner root sheath and hair shaft.

Sweat glands and hair follicles are determined by opposing signals, with BMPs promoting sweat glands and blocking BMPs leading to hair follicles.

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.

Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.

Certain factors can start hair growth in adult skin by making cells communicate and form new hair follicles.

Transplanted whisker follicles caused hair growth on the spine of mice.

Epidermal stem cells use integrin β1 and α6 as markers and CD271+ cells help maintain skin health and heal wounds.

A peptide known for reducing wrinkles also effectively inhibits an enzyme linked to skin inflammation and acne.

Mefloquine, an antimalarial drug, is effective in killing melanoma cells resistant to other treatments by causing lethal stress in the cells.

Using a stimulating cream shampoo before applying Minoxidil helps it penetrate hair follicles better, enhancing its hair growth-promoting effect.

Microneedle arrays deliver botulinum toxin effectively for sweat suppression, similar to injections.

Phenylephrine may help prevent hair loss from pulling on the hair roots.

Skin changes throughout life, from development before birth to aging effects like wrinkles, influenced by both genetics and environment.

LDE225 is a promising skin-applied treatment for basal cell carcinoma with good skin penetration and effectiveness.

Pregnancy can cause skin changes and may affect pre-existing skin conditions, with some treatments not safe for use during pregnancy.

Patients with SLE experienced non-scarring hair loss with fewer hair follicles, and DIF did not help identify lupus.

Women with lupus experienced non-scarring hair loss with fewer hair follicles, and the test for lupus in hair was not helpful.

Patients with systemic lupus erythematosus and hair loss had fewer hair follicles and non-scarring alopecia; direct immunofluorescence was not helpful in diagnosing lupus in these cases.

Hair loss in children can be caused by fungal infections, trauma, autoimmune disorders, or stress, and treatments vary depending on the cause.

Human hair growth involves active, resting, and intermediate phases, and examining plucked hairs can teach students about hair biology and diseases.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

Certain mature cells in mouse lungs can turn back into stem cells to aid in tissue repair.

Photobiomodulation therapy using red and near-infrared light can reduce inflammation and aid in healing various conditions.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Fat-related cells are important for initiating hair growth.

Understanding gene expression in hair follicles can reveal insights into hair growth and disorders.

β-catenin is essential for stem cell activation and proliferation in hair follicles.

DNA profiling in forensics has improved, but predicting physical traits and ancestry from DNA has limitations and requires ethical consideration.
