    TLDR Dexamethasone increases androgen receptor activity in scalp cells, which might explain stress-related hair loss.
    The study investigated the effects of dexamethasone (DEX), a synthetic glucocorticoid, on the activity of the androgen receptor (AR) in human dermal papilla (DP) cells. The researchers found that DEX treatment caused the glucocorticoid receptor (GR) to move into the nucleus of the cells. They also discovered that DEX increased the expression of AR mRNA in non-balding DP cells, which typically express low levels of AR without androgen. This increase was reduced by RU486, a GR antagonist. Additionally, AR moved into the nucleus following DEX treatment. The study concluded that stress-related hair loss might be due to increased AR expression and activity induced by DEX, even in non-balding scalps with low AR expression.

      The user reported early stage diffuse hair thinning and increased DHT levels after 4 weeks on Finasteride and 8 weeks on Finasteride plus 4 weeks on Dutasteride, despite the medications being authentic and stored properly. They are considering increasing their Dutasteride dosage due to the lack of side effects and are unsure if the treatment is helping their hair.
