Size-Dependent Penetration of Nanoemulsions into Epidermis and Hair Follicles: Implications for Transdermal Delivery and Immunization

Minoxidil can be effectively delivered through nanoemulsions containing eucalyptol or oleic acid, enhancing its diffusivity and targeting hair follicles. This contradicts the advice against mixing minoxidil with oils in topical formulations.

A peptide-based delivery system for finasteride shows promise in reducing systemic side effects while maintaining hair growth effectiveness. Combining this with other treatments like minoxidil and RU58841 could enhance results with lower systemic absorption.

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

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.

Iontophoresis and sonophoresis can enhance drug delivery into the scalp. Combining these methods may improve the effectiveness of topical treatments like dutasteride and certain peptides.

The conversation discusses the potential of using topical estrogen treatments for hair loss without systemic absorption, highlighting challenges and possible solutions like using estriol. It also mentions other treatments like topical finasteride, microneedling, and scalp massage, while noting the limitations and side effects of current options.
