Comparison of Glutathione S-Transferase and Cytochrome P-450 IA1 Activities in Cultured Keratinocytes and Reconstructed Epidermal Models

Isotretinoin may cause hair loss by increasing DHT through a precursor androgen, DHEAS. Treatments like topical antiandrogens (RU58841, pyrilutamide) and drugs increasing PPAR-y expression (pioglitazone) might prevent this hair loss.

RU58841 is used topically to prevent hair loss by blocking DHT, with suggestions to drink grapefruit juice, take breaks, avoid microneedling, and use lower concentrations to reduce side effects. Users discuss applying it at night to minimize systemic absorption.

A user speculates that a fast metabolism might affect the effectiveness of dutasteride for hair loss. Another user argues that drug response is unrelated to metabolism speed.

The conversation is about the potential dangers of taking oral minoxidil and grapefruit juice together. Some users express concern about dangerous drug interactions, while others argue that grapefruit juice may inhibit the metabolism of finasteride. The conclusion is that grapefruit juice may make finasteride less effective, but it won't affect minoxidil.

The conclusion of this conversation is that the user "DuckSeasonCamelSeasn" found that consuming grapefruit juice prior to taking finasteride or dutasteride helped them become a responder to the medications and regain hair growth. However, there are warnings about potential risks and interactions with other medications, so caution should be exercised.

The conversation discusses hair loss treatments, focusing on finasteride, minoxidil, and other options like PRP and ketoconazole. It highlights the importance of asking specific questions during a dermatology visit to determine the cause of hair loss and appropriate treatments.
