Drug Delivery to Hair Follicles

Microneedling can enhance hair growth by increasing drug absorption and activating stem cells, with different needle depths serving distinct purposes. Users report success with microneedling, often in combination with treatments like minoxidil and finasteride, and emphasize waiting periods for topical application to avoid side effects.

The conversation discusses hair regrowth using dissolvable microneedles loaded with rapamycin and epigallocatechin gallate nanoparticles. Specific treatments mentioned include Minoxidil, finasteride, and RU58841.

Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.

Microneedling is often combined with minoxidil for hair growth, but concerns about scalp damage, pain, and effectiveness deter some users. Alternatives like finasteride, dutasteride, tretinoin, and laser treatments are preferred by others.

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.

Microneedling is effective for hair growth, especially when combined with finasteride and minoxidil, but concerns exist about potential long-term skin damage. Users report increased collagen and elastin deposition, but the long-term effects on the scalp remain uncertain.
