Measurement of Cortisol in Human Hair as a Biomarker of Systemic Exposure

OP is using 5% minoxidil and a foligain supplement for hair loss, with blood test results showing high cortisol levels. OP is considering starting finasteride, while another user shares their experience with finasteride and hair loss challenges due to malabsorption issues.

The user has been taking 1mg finasteride daily for a year with no improvement in hair loss and reports low cortisol levels, sleep issues, and anxiety changes. The conversation includes discussions on the potential effects of finasteride on cortisol and neurosteroids, with suggestions to consult a doctor and consider other factors.

Corticosterone inhibits GAS6, affecting hair follicle stem-cell activity, with potential implications for stress-related hair loss. Ashwagandha and Vitamin K are suggested for reducing cortisol, but their effectiveness is debated.

Cortisol from stress can cause hair loss. Controlling cortisol levels improved the effectiveness of finasteride for hair regrowth.

Finasteride and Nizoral shampoo with Ketoconazole are used for hair loss treatment. Liquid Chromatography–Mass Spectrometry (LC-MS) is recommended over Enzyme-Linked Immunosorbent Assay (ELISA) for more accurate DHT testing.

The user is experiencing diffuse thinning and receded hairline, using dutasteride, minoxidil, and ketoconazole without regrowth, and was prescribed clobetasol propionate 0.05% with salicylic acid for possible inflammation. Other users caution against using the strong steroid without a serious condition, sharing experiences of adverse effects and alternative treatments for scalp issues.
