Literature Review: Topical Finasteride: To Use or Not to Use?

Topical dutasteride 0.05% is more effective for hair growth than oral finasteride 1mg, with minimal DHT reduction. The formulation uses castor oil and MCTs for better absorption but is not widely available until 2028.

A 23-year-old male with slight hair thinning is using ketoconazole shampoo, biotin, zinc, magnesium, D3/K2, and has just started topical finasteride (0.0125%). He plans to add minoxidil (4.5%) with 17α-estradiol and is seeking advice on the effectiveness and side effects of these treatments, as well as the use of a dermaroller.

A user shared their experience using topical finasteride for 6 months, showing a reduction in DHT levels but no visible improvement in hair loss. They are considering switching to oral finasteride for potentially better results.

Topical finasteride (P-3074) can inhibit scalp DHT by up to 70%, with some users experiencing systemic absorption similar to oral use. Users discuss varying application frequencies and concentrations, with some noticing side effects when overused.

Using topical finasteride with creatine might help reduce hair loss by targeting local DHT while maintaining normal systemic levels, but results are uncertain without testing. Users report mixed experiences with topical treatments like finasteride, dutasteride, RU58841, and minoxidil, with some seeing regrowth and others experiencing side effects.

An 18-year-old male stopped using finasteride due to side effects and plans to start topical dutasteride, considering it a potential solution with fewer side effects. He continues using minoxidil despite no noticeable results and is exploring other treatments like RU58841.
