Histopathology is not reliable for detecting early fibrosis in traction alopecia or for showing how severe it is.

Detailed patient history and physical exams are crucial for diagnosing hair loss.

The document concludes that accurate diagnosis of different types of hair loss requires careful examination of hair and scalp tissue, considering both clinical and microscopic features.

Cutting scalp biopsies in consecutive slices improves diagnosis of hair loss conditions.

Different fields of expertise must work together to better understand hair growth and create effective hair loss treatments.

Stem cells rearrangement regenerates functional hair follicles, potentially treating hair loss.

Liposomes can safely and effectively deliver substances to mouse hair follicles, potentially useful for human hair treatments.

Certain cells outside the hair follicle's bulge area can quickly regenerate damaged hair follicles, potentially helping to reduce hair loss from cancer treatments.

Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.

β-catenin in the dermal papilla is crucial for normal hair growth and repair.

Ethosomal minoxidil improves hair growth by penetrating deeper into skin and shortening hair cycle.

SV40 T antigen in hair follicles causes abnormal hair and health issues in mice.

The 3D skin model is better for hair growth research and testing treatments.

Artificial hair implantation using scaffolds is possible and PHDPE is more biocompatible than ePTFE.

Human hair keratins can self-assemble and support cell growth, useful for biomedical applications.

The dermal papilla is crucial for hair growth and health, and understanding it could lead to new hair loss treatments.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

The study found that a specific area of the hair follicle helps start hair growth by reducing the blocking effects on certain cells and controlling growth signals.

Hydrogel microcapsules help create cells that boost hair growth.

Deleting the Far2 gene in mice causes sebaceous gland issues and patchy hair loss.

The document suggests using hairpieces, wigs, and safe cosmetic techniques to hide hair loss from alopecia areata.

Pigmented casts are common in several hair loss conditions and can help diagnose specific types of alopecia.

The document concludes that treatments for cicatricial alopecia are not well-supported by evidence, but hair transplantation shows more predictable and satisfactory results.

Organotypic culture systems can grow skin tissues that mimic real skin functions and are useful for skin disease and hair growth research, but they don't fully replicate skin complexity.

Scalp psoriasis can cause different types of hair loss, with some patients developing permanent hair loss, and treatment may be stopped due to skin reactions.

There are many treatments for permanent hair loss disorders, but their effectiveness varies and there's no clear best option.

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

Hair becomes gray and thin as we age, and while most hair loss in older people is due to genetics, there's a chance for gray hair to regain color under certain conditions.

Hair thinning causes stem cell loss through a process involving Piezo1, calcium, and TNF-α.

Two-photon microscopy effectively tracks live stem cell activity in mouse skin with minimal harm and clear images.
