I am 27 years old, intact hairline, but probably Norwood III vertex. I used finasteride from 22 to 25 before stopping because I felt like it was negatively impacting my mood, etc.
I believe that yes this could be better than the what was used in the study. The formulation in the study didn't do any skin permeation tests or anything so I cannot say for sure though. It also depends on if Cetirizine needs to directly reach the hair follicle, or if just targeting eosinophils and other cells in the epidermis and dermis is enough. I don't know how the niosomal formulation directly targets/effects the hair follicle. But, I would bet on it being better because it forms a depot in stratum corneum and continuously releases from it.
As for topical formulation and what is best. It really depends on the drug and what you want to do. Transdermal penetration is MUCH different than local topical penetration. Transdermal assumes that it reaches systemic circulation.
In general what impacts absorption into the skin for transdermal delivery is:
- size of drug (< 400 Da)
- skin hydration of the site (basically want an occlusive barrier, through ointment etc)
- drug vehicle (drug should be more attracted to skin than the vehicle)
- retention (how long the drug is in contact with the skin)
- concentration of the drug in vehicle
- micro needling and other disruptive processes of the skin can impact absorption
- heat can also increase absorption
This is all for successful transdermal delivery however, in terms of hairloss, we do not necessarily want transdermal absorption, we do not want these drugs to go systemic. We want them to stay and work locally, which is what the niosomal formulation I detailed above will do.
**EDIT**
I forgot to mention that, yes, niosomes are quite easy to make, it may not be perfect in terms of size (like nanometers bc you need a sonicator or you could perhaps use extrusion for a cheaper alternative), but I made the above niosomes with no sonicator just fine. Many formulations may require a rotovap but you can build one yourself for fairly cheap.
good stuff. please stick around and keep us updated on this
what are you using for your hair now?
its says your back on finasteride and hydro cortisone in your regimen box? you ever thought of trying ru?
