Hair follicles are essential for skin health, aiding in hair growth, wound healing, and immune function.

The skin's dermal layer contains true stem cells with diverse functions and interactions that need more research to fully understand.

SARS-CoV-2, the virus causing COVID-19, can affect all endocrine organs and systems, altering their function and potentially leading to disorders. Factors like diabetes and obesity increase infection risk and severity. Understanding these effects is key for effective treatment.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

Scientists found cells in hair that are key for growth and color.

Tiny particles called extracellular vesicles could help with skin healing and hair growth, but more research is needed.

Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

Minoxidil works better when applied on a damp scalp than a dry one.

The microenvironment, especially mechanical forces, plays a crucial role in hair growth and could lead to new treatments for hair loss.

The document explains how hair follicles develop, their structure, and how they grow.

Hair color is influenced by genetics and can indicate certain health conditions.

Skin stem cells are crucial for maintaining and repairing skin, with potential for treating skin disorders and improving wound healing.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Caffeine penetrates human skin in lab tests similarly to real-life conditions, but actual skin use is still essential for accurate results.

Hair greying is caused by oxidative stress damaging hair follicles and melanocytes.

Squalene-based carriers improve delivery of a treatment to hair follicles for alopecia areata.

Scarring alopecia affects different hair follicle stem cells than nonscarring alopecia, and the infundibular region could be a new treatment target.

Heparan sulfate is important for hair growth, preventing new hair formation in mature skin, and controlling oil gland development.

Massage increases how deep both rigid and flexible liposomes can go into skin, with flexible ones going deeper, and covering the skin (occlusion) helps rigid ones more.

Effervescent formulations may improve minoxidil delivery, increasing effectiveness and reducing applications needed.

The document concludes that understanding hair follicles requires more research using computational methods and an integrative approach, considering the current limitations in hair treatment products.

An 81-year-old man's white hair began to regain its original color while he was treated with lenalidomide, suggesting that graying hair might be reversible.

Minoxidil can reduce functions related to androgen receptors.

Graying hair happens due to aging and might be delayed by new treatments.

The hair follicle bulge is an important area for adult stem cells involved in hair growth and repair, with potential for medical use needing more research.

Melanoma development can be linked to the breakdown of skin's melanin-producing units.

Topical L-thyroxine may help with wound healing and hair growth but should be used short-term due to potential risks.

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

The enzyme steroid sulfatase is linked to breast cancer and other conditions, and inhibitors are being developed for treatment.

Isotretinoin effectively treats severe acne and similar conditions, but has common, mostly reversible side effects, requiring careful patient monitoring.
