Androgens and SARMs play a role in body mass, frailty, skin health, and hair growth, and are used in treating prostate cancer, acne, and hair loss, with potential for new uses and improved versions in the future.

PrEP doesn't increase STI risk in high-risk men, anti-androgen drugs may lower ICU admission for male COVID-19 patients, a 3-point injection is better for crow's feet, and the 'Geriatric-8' tool could help assess frailty in older skin cancer patients.

The Rotterdam Study found risk factors for elderly diseases, links between lifestyle and genetics with health conditions, and aimed to explore new areas like DNA methylation and sensory input effects on brain function.

Hair transplantation is a safe, outpatient procedure for restoring hair in individuals with pattern hair loss or certain types of scarring, requiring a trained physician and team, with ongoing medical treatment recommended.

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

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

15-lipoxygenase helps keep skin healthy by reducing inflammation.

MRI can effectively image skin structures noninvasively.

Skin tags in obese individuals may indicate higher cardiovascular risk.

Dog skin with hair loss, when transplanted to mice, regrew hair, suggesting the hair loss cause is likely body-wide, not skin-specific.

Removing centrosomes from skin cells leads to thinner skin and stops hair growth, but does not greatly affect skin cell differentiation.

Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.

Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.

Memory T cells in the skin balance staying put and moving into the blood, clustering around hair follicles, and increasing in number after infection.

Skin grafts on mice can cause an immune response leading to hair loss, useful for studying human hair loss conditions.

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

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

Restoring mitochondrial function in mice reversed their skin wrinkling and hair loss.

Skin bacteria, specifically Staphylococcus aureus, help in wound healing and hair growth by using IL-1β signaling. Using antibiotics on skin wounds can slow down this natural healing process.

MRL/MpJ mice's skin wounds heal with scars, unlike their ear wounds which can regenerate.

A 3-month stay in space causes skin thinning, disrupts hair growth, and changes muscle-related genes in mice.

Changes in skin microbes play a role in some skin diseases and could lead to new treatments.

MicroRNAs play a crucial role in skin and hair health, affecting everything from growth to aging, and could potentially be used in treating skin diseases.

Spiny mice are better at regenerating hair after injury than laboratory mice and could help us understand how to improve human skin repair.

New skin substitutes for treating severe burns and chronic wounds are being developed, but a permanent solution for deep wounds is not yet available commercially.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

A new liposome treatment helps heal deep burns on mice by improving hair regrowth and reducing scarring.

The research suggests that a specific skin gene can be controlled by signals within and between cells and is wrongly activated in certain skin diseases.

EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.

Non-invasive methods show promise for diagnosing skin diseases like psoriasis and lupus but need more research for regular use.
