Some vitamins and minerals are important for preventing hair loss, but treating hair loss with them without a known deficiency is not proven effective.

Higher miR-34a levels and the A variant of the MIR-34A gene are linked to increased risk and severity of alopecia areata.

Keratinocytes help heal skin wounds by interacting with immune cells and producing substances that kill pathogens.

Scientists created a new 3D skin model from cells of plucked hairs that works like real skin and is easier to get.

Hair follicle cells resist turning into skin cells.

RSPO1 mutations in certain patients lead to skin cells that don't develop properly and are more likely to become invasive, increasing the risk of skin cancer.

Prostaglandin D2 increases testosterone production in skin cells through a process involving reactive oxygen species, which could be a new target for treating hair loss and other skin conditions driven by testosterone.

The study created hair-bearing skin models that lack a key protein for skin layer attachment, limiting their use for certain skin disease research.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Mesenchymal stem cells show promise for treating various skin conditions and may help regenerate hair.

Deleting the CD271 gene in mouse skin cells leads to disorganized skin and increased hair growth, suggesting CD271 is important for skin health.

The conclusion is that the nuclear lamina and LINC complex in skin cells respond to mechanical signals, affecting gene expression and cell differentiation, which is important for skin health and can impact skin diseases.

Human skin can make serotonin and melatonin.

The skin produces and uses vitamin D for bone health, cell growth, and immune function.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Intu gene is crucial for hair follicle formation by helping keratinocytes differentiate through primary cilia.

The new assay can track and measure melanosome transfer between skin cells, confirming filopodia's role in this process.

Researchers developed a method to create artificial hair follicles that may help with hair loss treatment and research.

Adding hyaluronic acid helps create larger artificial hair follicles in the lab.

New treatments for immune disorders caused by FOXN1 deficiency are promising.

MicroRNAs are important for skin health and could be targets for new skin disorder treatments.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Collagen XVII is important for skin aging and wound healing.

Human skin responds to light with protective mechanisms, but more research is needed to understand these processes and their implications for health and therapy.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

Permanent hair dye mixtures can irritate and damage the skin.

Researchers created a potential skin substitute using a biodegradable mat that supports skin cell growth and layer formation.

The conclusion is that pharmacists are important in helping women choose the right skin care treatments.

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

Mouse skin can produce and process serotonin, with variations depending on hair cycle, body location, and mouse strain.
