The model better predicts how water-loving and fat-loving substances move through the skin by including tiny pores and hair follicle paths.

The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.

A hormone affects hair growth, certain molecules may prevent skin damage, a skin disease is linked to immune cells, glycerol helps skin hydration, and psoriasis treatment trials need improvement.

New method measures skin cell turnover quickly and effectively, showing turnover slows with age and responds more to treatments in older skin.

The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.

Somatostatin may help protect hair follicles from immune attacks.

Ethosomal carriers effectively deliver hair loss drug into skin.

TGF-alpha is present in sheep and ferret skin and may affect hair growth without directly stimulating cell proliferation.

Scalp cooling devices need to be powerful enough to overcome heat loss and reach the right temperature to prevent hair loss from chemotherapy.

People with alopecia areata have similar retinal structures but thicker choroidal regions compared to those without the condition.

Hair follicles can regenerate after radiation damage but not during a specific growth phase.

Hair follicle stem cells can return to their original niche and help regenerate hair.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

Hair follicle stem cells helped heal a severe scalp burn without needing traditional skin grafts.

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

Different markers are found in stem cells of the scalp's hair follicle bulge and the surrounding skin.

The method increases stem-like cells for better skin regeneration.

Understanding hair biology is key to developing better treatments for hair and scalp issues.

UV radiation damages hair by creating holes and peeling cuticle layers.

Tying a knot can measure hair friction, useful for medical applications.

Gentamicin penetrates pig skin better through open hair follicles than blocked ones.

Hair damage increases significantly with higher temperatures and longer heating times.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

Microfluorometry effectively measures how much polymer coats and penetrates hair, useful for evaluating hair products.

Plant-based treatments can effectively and safely treat hair loss.

Skin may help in getting rid of excess iron through the process of skin cell renewal.

Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.
