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.

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 user has been mixing finasteride with stemoxydine for hair loss and is considering switching to a less expensive product with a different ingredient list. They are questioning if the new product's higher water content compared to alcohol will affect the finasteride's solubility.

A user is seeking feedback on a homemade topical finasteride formula for hair loss, consisting of 7.5 mg of finasteride, propylene glycol, ethanol, and distilled water. They aim to achieve a 0.0125% solution by applying 2 ml daily.

Topical finasteride with hydroxypropyl chitosan shows significantly less serum absorption and minimal DHT reduction compared to oral finasteride. Users need the specific chitosan formulation to avoid side effects seen with regular ethanol+PG solutions.

The conversation discusses how to use fluridil/topilutamide with other hair loss treatments like liquid minoxidil and CB-03-01, considering fluridil's hydrophobic nature and potential degradation with water. The user questions the necessity of washing hair only once per week as suggested by the manufacturer.

Liposomal carriers for topical finasteride offer better targeting, reduced side effects, and less irritation compared to alcohol-based solutions, but availability and cost may limit their use. Minoxidil can dissolve in liposomal carriers, enhancing delivery and stability.

Topical finasteride in a liposomal formulation reduces systemic absorption compared to ethanol solutions. The user is seeking sources for such products, noting that popular options like morr-f are not liposomal.

RU-58841 does not dissolve well in common Minoxidil solutions due to water content, requiring a 70/30 ethanol/propylene glycol mix. Users report using separate solutions for RU-58841 and finasteride/Minoxidil for better results.

Hydrocortisone is not recommended for long-term use on the scalp due to potential side effects like thinning and steroid-related issues. Alternatives like foam minoxidil or oral minoxidil are suggested, though foam may be less effective.

The conversation discusses the potential for developing a biologic "DHT sponge" to neutralize DHT in the bloodstream as a treatment for hair loss, suggesting it could be more targeted and have fewer side effects than current treatments like finasteride and dutasteride. Concerns include the complexity, cost, and potential side effects of such a treatment, as well as skepticism about its feasibility and market interest.

The conversation discusses using Rogain foam as a solvent for topical finasteride due to an allergy to propylene glycol. The foam's ingredients, including alcohol SD 40B, are considered suitable for dissolving finasteride for easier application without skin irritation.

New product Tomorrowlabs HSF targets hair loss through HIF pathway indirectly by removing scalp iron. Minoxidil and Stemoxydine also relate to HIF pathway.

Ethosomes are suggested as an effective delivery method for topical finasteride solutions, requiring the addition of a phospholipid like soya lecithins. The user questions why do-it-yourself solutions don't commonly use ethosomes despite their potential benefits.

Silicone-based shampoos and conditioners may leave a layer on the scalp that could affect the absorption of topical hair loss treatments like Fluridil. The user is considering switching to silicone products to manage frizzy hair but is concerned about this potential issue.

The conversation is about finding a pure high molecular weight hyaluronic acid for the scalp after microneedling. A user suggests using a product from The Ordinary.

The user is using a topical solution containing 1% finasteride and 5% minoxidil for hair loss, with water, glycerin, and PEG-40 hydrogenated castor oil as carrier agents. They are questioning if these ingredients are effective carriers after using the solution for three months.

The conversation discusses how the absorption rate of topical finasteride varies and is not equivalent to its oral form, with only a small percentage reaching the scalp. It also mentions that minoxidil in high concentrations is used topically because only a small amount is absorbed.

The conversation is about using a topical serum for hair loss with ingredients like finasteride and minoxidil, and the option to exclude retinoic acid and hydrocortisone due to concerns about long-term effects. One user prefers using only finasteride, avoiding minoxidil and retinoic acid, and plans to remove hydrocortisone in future orders.

Oral hyaluronic acid is not beneficial for hair, as it gets broken down in the stomach and has no strong evidence supporting its effectiveness. The user is taking finasteride, dutasteride, and topical minoxidil for hair loss, but combining finasteride and dutasteride is considered redundant.

Switching from propylene glycol to glycerin in topical finasteride may reduce systemic absorption and side effects while maintaining local scalp DHT suppression. Concerns exist about glycerin's ability to deliver the full dose to hair follicles.

Topical finasteride results in plasma levels 100 times lower than oral finasteride, potentially reducing systemic side effects. Users report similar efficacy with fewer side effects, suggesting a preference for topical application.

Topical finasteride may reduce more scalp DHT but is seen as inconsistent and messy compared to oral finasteride. Users report mixed results with both forms, with some preferring oral for its convenience and consistent dosing, while others find topical effective but harder to apply.

A user is considering switching from oral to topical finasteride to reduce systemic DHT impact and is exploring ethossomal finasteride for better skin penetration and potential hair regrowth. They found ethossomal finasteride in Brazil and are seeking opinions on its effectiveness compared to other topical delivery methods.

Dutasteride has a larger volume of distribution than finasteride due to its lipophilic nature, allowing it to concentrate in hydrophobic areas and making it difficult to excrete. A user experiencing hair loss has been using oral finasteride for 10 months with minimal regrowth and is considering switching to dutasteride or adding oral minoxidil.

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.

Topical finasteride is believed to reduce scalp DHT more than oral forms, but its effectiveness is questioned due to inconsistent application and absorption. Oral finasteride is considered more effective because it consistently reduces systemic DHT, ensuring more reliable results.

The conversation discusses a new liposomal topical finasteride from Hasson and Wong, available in Canada and Italy, soon in the US, costing $40/month. It claims to reduce scalp DHT by 50% without affecting serum DHT, potentially benefiting those who can't tolerate oral finasteride or RU58841.

The user seeks alternatives to Propylene Glycol (PG) for delivering topical finasteride due to scalp irritation. They consider using Propanediol 1,3 and ask for other suggestions.

The conversation discusses the possibility of creating liposomal topical finasteride at home or at a local pharmacy, questioning if it is an expensive or proprietary technology. It also mentions making topical finasteride using alcohol and propylene glycol.
