Study on Oil-in-Water Nanoemulsion-Based Local Transdermal Delivery System

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.

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

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.

The conversation discusses using high molecular weight hyaluronic acid after microneedling to form a protective barrier, though it's considered expensive and offers marginal improvement. Users share experiences with different microneedling tools like derma rollers, dermastamps, and Dr. Pen, with some opting not to use any products on the scalp.

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.

The conversation is about whether castor oil can be effectively used alone after microneedling without a penetration enhancer like DMSO or ethanol. The user believes microneedling-induced wounds might be enough for absorption.
