    TLDR The new X-ray technique allows for precise and non-destructive measurement of elements in hair, creating the first database of its kind for a specific ethnic group.
    In 2001, a new non-destructive X-ray fluorescence technique was developed for estimating elemental content in biological tissues, specifically human hair fibers. The ITRAX X-ray spectrometer was evaluated and found to allow for precise, fast, non-destructive, simultaneous, quantitative recording of detected elements and trace elements down to levels of 1 ppm (microg/g). The technique was used to assess normal values of physiologically important elements present in hair in a cohort of normal, healthy Swedish, Caucasian individuals. The results showed that concentrations of elements varied as functions of the diameter of the analyzed hair volume. This database, constructed from data retrieved from a homogeneous ethnic set of individuals, was the first of its kind.

      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.

      community Anyone use hair fiber products like Toppik?

      in Question  21 upvotes 5 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.

      Minoxidil with alcohol and propylene glycol was more effective than non-alcohol versions, and RU58841 worked best in a non-water-based solution. Oral finasteride showed better results than topical, despite side effects; microneedling and tretinoin worsened hair loss, and PRP was only helpful when younger.

      The user experienced hair loss since 2019 and tried finasteride, dutasteride, RU58841, and ketoconazole shampoo without success. A scalp biopsy showed scarring and inflammation from folliculitis, indicating chronic inflammation was affecting treatment effectiveness.
