    TLDR Hair tissue can help monitor environmental and public health risks.
    The study reviewed experimental diffraction and spectral analyses of hair tissue, focusing on the effects of various factors on its molecular and nanostructural ordering. Using X-ray fluorescence and diffraction with synchrotron radiation, researchers attributed hair's diffraction pattern to two fibrillar systems: intermediate keratin filaments and proteoglycan fibrils. The study examined how personal hygiene products and medicines affected hair's structural transformation and elemental composition. Proteoglycans were highlighted as key components maintaining structural homeostasis in biological tissues. The research suggested that hair tissue could be a valuable diagnostic material for monitoring environmental and public health risks.

      community Topical finasteride now the safest possible path?

      in Finasteride/Dutasteride  84 upvotes 1 year ago
      Topical finasteride is considered a safer option for hair regrowth with fewer systemic side effects compared to oral finasteride. Some users report similar efficacy and side effects between topical and oral treatments, while others prefer topical due to reduced systemic exposure.

      community Starting Finasteride After Being on Oral Minoxidil 19M

      in Minoxidil  3 upvotes 4 months ago
      A 19-year-old is using 2.5 mg oral minoxidil for hair loss and plans to add finasteride later, but is concerned about potential hair loss after starting finasteride. Others advise starting finasteride sooner to prevent further hair loss, noting that shedding is a normal part of the process.

      A user traveled to Turkey to buy 72 packages of Dutasteride for a year-long supply and successfully brought them back home. They plan to use 2.5mg of Dutasteride daily along with RU58841 for hair loss.

      community Anyone use hair fiber products like Toppik?

      in Question  21 upvotes 6 years ago
      User phoenixblue asked about hair fiber products like Toppik and if they cause hair loss by clogging pores. Replies suggested that Toppik is safe, but effectiveness varies; some users experienced no hair loss, while others had issues with color or sweating.

      community If You Have DUPA, PLEASE READ THIS: Everyone Should Be Scalp Biopsied

      by nkrata in Research  830 upvotes 1 year 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.
