    GlossaryHair Types (Hair Classifications)

    categorizes hair by curl pattern, thickness, and structure

    Hair types, also known as hair textures or hair classifications, refer to the categorization of hair based on its curl pattern, thickness, and overall structure. The most common system classifies hair into four main types: Type 1 (straight), Type 2 (wavy), Type 3 (curly), and Type 4 (coily or kinky), with further subcategories (A, B, C) within each type to describe variations in curl tightness and texture. Understanding hair types is crucial for selecting appropriate hair care products and treatments.

      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.
