Hair follicle regeneration in skin grafts may be possible using stem cells and tissue engineering.

People with alopecia areata have higher levels of osteopontin, which might be important in the disease's development, but this doesn't relate to how severe the disease is.

Stem cell therapy may help treat tough hair loss cases.

A substance called VIP might protect hair follicles from being attacked by the immune system, and problems with VIP signaling could lead to hair loss in alopecia areata.

miR-195-5p reduces hair growth ability in cells by blocking a specific growth signal.

Calcium microcapsules are better for long-term use in artificial dermal papilla, while barium microcapsules are good for short-term.

Erdr1 could be a new marker for diagnosing hair loss.

Neural progenitor cell-derived nanovesicles help hair growth by activating a key signaling pathway.

Tiny particles from brain cells help hair grow by targeting a specific hair growth pathway.

Sweat glands and hair follicles are structurally connected within a specific layer of skin fat.

Horizontal scalp biopsy sections effectively diagnose and predict MPAA, with follicular density and inflammation impacting hair regrowth.

Transverse scalp sections are better for diagnosing non-scarring hair loss, while vertical sections are better for a specific scarring hair loss called lichen planopilaris.

The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.

The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.

Ionizing radiation damages human hair follicles by stopping cell growth, causing cell death, disrupting color, and increasing stress and damage markers.

Bimatoprost, a glaucoma medication, may also help treat hair loss.

Researchers developed a new method using methylene blue staining to more accurately identify the growth stage of human hair follicles.

Spermidine may help reduce hair loss and deserves further testing as a treatment.

The debate focuses on the role of catagen and hair shedding mechanisms in telogen effluvium.

Both parties agree that cell death is important in the hair cycle, but they have different views on the role of the catagen phase and hair shedding.

Guidelines for diagnosing common hair loss include detailed history, clinical examination, and various diagnostic techniques.

Senescent alopecia is a type of hair loss that occurs after age 50, not caused by genetics, and involves a gradual thinning of hair without significant inflammation.

Inaudible sound at 30 kHz can boost hair growth and decrease hair loss by promoting cell growth and reducing cell death in hair follicles.

Alopecia areata is an autoimmune disease causing hair loss, treatable with immune-modulating drugs, and linked to genetics.

Interleukin-15 can help hair growth and protect hair follicles.

AGA patients have fewer hairs and smaller follicles; T:V ratio above 4:1 may indicate AGA.

Growing hair cells with dermal cells can potentially treat hair loss.

Horizontally sectioned scalp biopsies are more reliable for diagnosing hair loss in women when three samples are taken instead of one.

The conclusion is that normal scalp hair counts for Taiwanese people were established, showing age-related differences but not sex or scalp location differences.

Different scalp imaging methods are important for studying hair and scalp health and require more volunteers for better evaluation.
