    Did you mean Skin Barrier Dysfunction?
    Glossary Skin Barrier Dysfunction

    Skin barrier dysfunction refers to the impaired ability of the skin to act as a protective barrier, which can lead to increased transepidermal water loss and susceptibility to irritants, allergens, and pathogens. In the context of hair loss, a compromised skin barrier can affect the scalp's health, potentially leading to inflammation and conditions such as seborrheic dermatitis or psoriasis, which may contribute to hair thinning or loss. Key distinguishing characteristics include alterations in skin hydration, texture, and the presence of inflammatory markers, which can impact hair follicle function and overall hair growth.
