A Lichenoid Reaction, also known as Lichenoid Dermatitis, is an inflammatory skin condition characterized by a rash that resembles lichen planus.

This reaction involves an immune response where T-cells attack the skin, leading to damage and inflammation.

community Diffuse hair loss and scalp biopsies

in Research 692 upvotes 4 months ago

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
