TLDR Cationic polymers improved liposome stability and increased skin absorption of aciclovir and minoxidil.

This study from 12 years ago investigated the use of cationic polymers to improve the physicochemical stability of DPPC liposomes and increase skin permeation of aciclovir and minoxidil. The addition of chitosan and Eudragit EPO-coated liposomes increased skin permeation efficiency, possibly due to the positively charged liposomes interacting stronger with the skin surface or the polymers interacting with skin lipids and disrupting tight junctions in lower epidermis layers. The study found that the addition of EU improved the skin permeation of minoxidil.

community Could the salicylic acid in my Nioxin shampoo reduce minoxidil effectiveness?

in Minoxidil 3 upvotes 2 days ago

Salicylic acid in Nioxin shampoo may reduce minoxidil effectiveness by inhibiting sulfotransferase activity, potentially causing hair loss. Users suggest stopping salicylic acid use or trying alternative treatments like high-concentration tretinoin or medicated minoxidil/finasteride shampoos.

community Minoxidil asking advice as an 23F

in Minoxidil 1 upvotes 3 days ago

A 23-year-old woman is considering starting minoxidil for hair thinning but is concerned about its long-term use and effectiveness. Recommendations include consulting a doctor, checking ferritin levels, and considering treatments like spironolactone or finasteride, while minoxidil is suggested for regrowth but not as a primary treatment.

community Using minoxidil for 6 months. Not seeing results

in Minoxidil 107 upvotes 5 days ago

Minoxidil alone is not effective for hair regrowth; adding a DHT blocker like finasteride or dutasteride is recommended. Dermastamping and micro-needling can enhance results, and some users suggest trying oral minoxidil or natural DHT blockers.

The user is using Dutasteride (90.5mg) and Minoxidil (2.5mg) for hair loss since October 2025 and is seeking feedback on progress by comparing photos from October 2025 and January 2026. They are asking for opinions on whether the treatment shows improvement.

community How to properly combine topical Pyrilutamide (KX-826) and Minoxidil? Timing question.

in Minoxidil 1 upvotes 1 week ago

Combining topical minoxidil and pyrilutamide (KX-826) for hair loss treatment. It is suggested to apply minoxidil first, wait 20 minutes, then apply pyrilutamide for better absorption.

community Will minoxidil cause your skin to age from the collagen inhibition?

in Minoxidil 2 upvotes 1 week ago

Minoxidil is unlikely to cause skin aging at typical doses, and concerns about collagen inhibition are mostly unfounded. Users suggest using sunscreen and tretinoin for skin health, and some combine minoxidil with finasteride for hair maintenance.
