    GlossaryTandem Mass Spectrometry

    analyzes molecules by breaking them into fragments twice

    Tandem Mass Spectrometry (MS/MS) is an advanced analytical technique used to identify and quantify molecules in a sample by breaking them into smaller fragments. It involves two stages of mass spectrometry: the first stage isolates the molecule of interest, and the second stage analyzes the fragments produced after the molecule is broken apart. This method is highly sensitive and specific, making it valuable for applications in fields like biochemistry, pharmacology, and environmental science.

      The conversation discusses whether finasteride's reduction of DHT and increase in scalp testosterone contribute to hair follicle miniaturization. Some participants argue testosterone does not cause miniaturization, while others suggest that even with reduced DHT, other androgens like testosterone may still contribute to hair loss.
