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

Seborrhoeic dermatitis may cause a condition called "seborrhoeic folliculitis," leading to chronic scalp inflammation and scarring hair loss.

A condition with certain scalp changes may come before acne keloidalis nuchae and other similar hair loss disorders.

The document concludes that "hot comb alopecia" is now called "central cicatricial centrifugal alopecia" and its causes are complex.

Early treatment is key to prevent permanent hair loss from scalp conditions that cause scarring.

Accurate diagnosis is key for treating different kinds of hair loss, and immune response variations may affect the condition and treatment results.

Betacoronaviruses, like COVID-19, may cause hormone system dysfunction and affect disease susceptibility and severity.

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

The conclusion is that Erosive Pustular Dermatosis of the Scalp is a rare condition best treated with strong topical steroids and sometimes systemic treatment.

Elastin staining helps assess late-stage scarring alopecia but is not definitive, and clinical diagnosis is still crucial.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

Trichoscopy helps tell apart Frontal Fibrosing Alopecia and Lichen planopilaris by showing different hair and scalp features.

The conclusion is that FFA and LPP have similar scalp biopsy features, making them hard to distinguish histologically, and FFA may be a specific kind of scarring hair loss.

Trichoscopic features help diagnose and assess female pattern hair loss severity, with inflammation playing a key role.

Psoriasis can cause temporary or permanent hair loss.

Wnt signaling is crucial for skin wound healing and reducing scars.

Overexpression of activin A in mice skin causes skin thickening, fibrosis, and improved wound healing.

Androgen hormones cause hair follicle scarring in hair loss, and finasteride helps reduce it.

Mast cells might contribute to hair loss by causing skin thickening.

The Wnt/β-catenin pathway helps tissue regeneration but can also cause fibrosis, and drugs that inhibit this pathway may aid in healing skin and heart tissues.

High levels of ERK activity are key for tissue regeneration in spiny mice, and activating ERK can potentially redirect scar-forming healing towards regenerative healing in mammals.

The document concludes that a better understanding of cell changes during wound healing could improve treatments for chronic wounds and other conditions.

Fibrosing alopecia in a pattern distribution is a unique hair loss condition that may respond to antiandrogen therapy.

The study found that the cause of alopecia areata can be identified through tissue analysis, and vertical sections are enough for diagnosis.

Frontal Fibrosing Alopecia may be a complex condition linked to hormonal changes in women, not just a form of Lichen Planopilaris.

The hair follicle's connective tissue is a key source of a certain collagen in human scalp skin.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

Activin helps skin growth and healing mainly through stromal cells and affects keratinocytes based on its amount.

Researchers found a white halo around hair in most patients with a specific type of hair loss, which helps in early diagnosis and treatment.

Postmenopausal frontal fibrosing alopecia is a type of hair loss in postmenopausal women that may stop on its own but has no effective treatment.
