Topical finasteride may have higher systemic absorption and lower efficacy when using a Propylene Glycol/Ethanol formulation compared to the hydroxypropyl chitosan (HPCH) formulation. The safety profile of topical finasteride relies heavily on the HPCH formulation, and using standard solutions might lead to different pharmacokinetics.

The conversation is about using distilled water as a solvent for topical finasteride to reduce systemic absorption. The user is considering avoiding ethanol and propylene glycol to achieve this.

The regimen includes using a diluted 5.5% Minoxidil / 0.025% Finasteride solution daily, microneedling weekly, and ketoconazole shampoo twice a week to minimize systemic exposure while maximizing scalp DHT reduction. The goal is to achieve hair regrowth with minimal side effects.

The conversation discusses using estradiol mesotherapy to replicate hormone replacement therapy results while minimizing systemic exposure. It also covers the use of Spironolactone cream, which reportedly has no systemic side effects, and the potential risks of using bicalutamide and Spironolactone in men.

A user is considering using a topical compound of 0.25% finasteride and 5% minoxidil for hair loss, concerned about side effects experienced with oral finasteride. Other users suggest starting with a lower concentration and possibly diluting the solution to minimize side effects.

Topical finasteride combined with oral minoxidil is used by some for hair loss, with mixed results; some users report success while others find it difficult to apply. Alternatives like oral finasteride and microneedling are also considered, with some users experiencing hair stabilization and new growth.

Topical finasteride is generally considered more effective than topical dutasteride due to better scalp absorption. Users suggest combining topical finasteride with minoxidil and tretinoin while reducing oral dutasteride dosage to minimize side effects.

Topical finasteride was ineffective for some users, leading to hair loss, while others found it beneficial. Alternatives like oral finasteride, dutasteride, minoxidil, and combinations with tretinoin and keto shampoo were suggested.

A 25-year-old shared progress pictures after using 0.3% topical finasteride and 8% minoxidil for a year, showing improved hairline and positive feedback. They use a telehealth solution from Happy Head and CVS foam minoxidil.

The user is considering switching from topical finasteride to RU58841 or KX826 to reduce side effects but decides to stick with finasteride for now. Users discuss the effectiveness and risks of RU58841 and KX826, with finasteride being considered the most reliable option.

Topical finasteride may be more effective than dutasteride for some individuals, with some users reporting better results with finasteride. Combining finasteride and dutasteride in a topical formula is questioned for its effectiveness.

Topical finasteride in DMSO is discussed as a potential treatment for hair loss. Users share experiences and opinions on its effectiveness.

Topical finasteride unexpectedly cleared the user's severe facial acne, which they attribute to reduced DHT levels. Another user shared a similar experience with topical minoxidil and oral finasteride, noting reduced acne and scarring.

Topical finasteride, specifically Fynzur spray, is used for diffuse thinning in long hair, but many find the cone applicator ineffective and suggest applying directly to the scalp. Some users recommend oral finasteride for more even results, while others combine it with minoxidil for better effectiveness.

Topical finasteride can be effective for some, especially if oral finasteride causes side effects, but results may vary and can be slower. Combining topical finasteride with minoxidil is common, though some users switch to oral treatments for better results.

Topical finasteride concentrations are likely much higher than necessary for effective follicular DHT suppression, with current standards being 100-1000 times above the theoretical minimum. Lower concentrations (0.001-0.0025%) might still work locally while minimizing systemic exposure.

A 35-year-old male from the UK experienced significant hair regrowth and thickening after using topical finasteride 0.1% and minoxidil 5% spray for three months, along with a derma roller and Nizoral shampoo. He reported no side effects and encouraged others to try the topical spray if concerned about tablet side effects.

The user experienced thicker hair and less hair loss after using topical finasteride (0.5%) and minoxidil (5%) foam for four months, with minimal side effects compared to oral finasteride. They also use a derma needler and injectable testosterone, noting no increased hair loss despite higher testosterone levels.

The user shared a 2-month progress update using topical finasteride and minoxidil for hair loss. The conversation included comments on the user's appearance and potential side effects.

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.

Users discuss making topical finasteride solutions by dissolving crushed tablets in ethanol and propylene glycol, with concerns about residue affecting effectiveness. They also mention using minoxidil and oral finasteride, noting some hair regrowth and no side effects from topical use.

Topical finasteride with minoxidil effectively stabilized and thickened hair but caused side effects like brain fog, reduced libido, and emotional flattening, leading to discontinuation. The user switched to a new regimen including minoxidil, KX-826, and other treatments, noting improvements in libido and vivid dreams after stopping finasteride.

Topical finasteride can effectively reduce scalp DHT by targeting local enzymes, despite less systemic impact compared to oral forms. Combining oral dutasteride with topical finasteride and minoxidil may enhance hair loss prevention, though evidence of its effectiveness is limited.

Topical Finasteride is most effective at 0.1-0.25%, and Minoxidil at 5%. Tretinoin is optional, and additional ingredients like biotin, caffeine, and saw palmetto are recommended.

Topical finasteride is currently more effective than pyrilutamide for hair loss. Combining treatments like topical finasteride and pyrilutamide may enhance results due to different mechanisms.

Topical finasteride absorption starts almost instantly, but the exact time needed for full absorption is unclear. Users suggest it may not need to stay on all day.
