5 / 1000+ resultsresearch Hair follicle targeting with curcumin nanocrystals: Influence of the formulation properties on the penetration efficacy
This study found that curcumin nanocrystals efficiently penetrated hair follicles down to the lower infundibulum in an ex-vivo pig ear model, regardless of the gel vehicle used, though passive dermal penetration varied with the vehicle’s skin hydrating properties.
research Effect of Charge Carrier Lipid on Skin Penetration, Retention, and Hair Growth of Topically Applied Finasteride-Containing Liposomes
This study found that finasteride-containing anionic liposomes enhanced skin retention and had moderate hair growth efficacy, suggesting potential for treating androgenetic alopecia with reduced systemic side effects.
research Investigation of penetration abilities of various oils into human hair fibers
Some oils can penetrate hair and reduce the stickiness between fibers, but mineral oil cannot.
research The penetration efficiency of a dissolved model drug into hair follicles depends on the concentration of added nanoparticles
In this study, using an ex vivo porcine skin model, researchers found that a 4% nanoparticle concentration significantly enhanced the transport of fluorescein sodium into hair follicles compared to a 2% concentration, while higher concentrations did not further increase penetration depth.

5 / 1000+ resultscommunity So I earlier used to use the alchol variant but it lead to dryness in scalp and I switched to a non alchol variant that contains oleanolic acid , is it more or less the same , coz I heard alchol helps in better penetration so wondering if this would reduce my hair growth.
The user switched from an alcohol-based Minoxidil to a non-alcohol variant with oleanolic acid due to scalp dryness. They are concerned if the non-alcohol variant will be less effective for hair growth.
community Is the “crunching” sound during microneedling my scalp actually the needles cutting through hair?
The "crunching" sound during microneedling is likely the needles penetrating the scalp's outer layers, not cutting hair. Users suggest using a derma stamp instead of a roller to avoid potential hair damage.
community Can microneedling damage existing hair?
Microneedling is unlikely to damage existing hair if done with a device using a smaller needle count, like a 9-needle cartridge, and a stamping motion. Hair follicles are deeper than the typical needle penetration depth.
community Has Anyone Heard About Ethossomal Finasteride? 6x Finasteride Delivery in Hair Folicule?
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.

7 / 801 results- Do you want finasteride to penetrate better? The ideal solvent to maximize its effect. Formulation sources describe propylene glycol and microemulsion vehicles as increasing how much topical finasteride crosses the skin, but better penetration has not been shown to mean better hair results, and it also raises systemic exposure. The vehicle and strength are decisions for a prescriber or compounding pharmacist.
- Do hair fibers really make thinning hair look fuller, or is it just an illusion? Hair fibers create an optical illusion of fullness but do not actually thicken hair.
- How do you apply hair fibers correctly so they stay in place all day? Apply hair fibers to clean, dry hair and use a setting spray for better hold.
- Can hair fibers be used along with medical treatments like minoxidil or finasteride? Yes, hair fibers can be used with minoxidil or finasteride without any chemical interaction.
