    GlossaryPharmacokinetics (drug kinetics)

    study of how drugs move through the body

    Pharmacokinetics (PK) is the study of how a drug moves through the body over time. It involves four main processes: absorption (how the drug enters the bloodstream), distribution (how the drug spreads through the body's tissues), metabolism (how the body breaks down the drug), and excretion (how the drug is eliminated from the body). Understanding PK helps in determining the appropriate dosage and frequency of medication to ensure its effectiveness and safety.

      Quitting vaping significantly reduced hair loss for a user who was a heavy vaper and also taking finasteride. Some participants suggest nicotine's vasoconstrictive properties may worsen hair loss, while others share personal anecdotes of hair improvement after quitting smoking or vaping.
