This study observed that particles sized 300-600 nm penetrate hairfollicles more efficiently, likely due to alignment with the thickness of the human hair cuticula.
In this study, porcine collagen acellular dermal matrix scaffolds combined with mice platelet-rich plasma were associated with increased hair density and follicle regeneration in mice with alopecia, suggesting a potential therapeutic approach.

In this study, FITC-labeled BSA nanocarriers delivered a model drug deeper into porcine ear skin hairfollicles than the carriers themselves, as shown by confocal microscopy.
Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
Various peptides are discussed for treating male pattern baldness, with some available for topical use like GHK-Cu and Ac-KGHK, while others remain in research stages. Users are interested in experiences and sourcing these treatments.
Hairfollicle stem cells remain in bald individuals, but progenitor cells do not, raising questions about hair regrowth claims by Pelage. PP405 is discussed as a potential treatment, with skepticism about its effectiveness compared to existing treatments like Minoxidil and Finasteride.
A breakthrough in hairfollicle cultivation using induced pluripotent stem cells (iPSCs) has been achieved, producing large hairfollicles suitable for transplantation. Clinical trials for this hair multiplication technology are planned in partnership with Yinguan Biotechnology.
PP405 aims to reactivate hairfollicle stem cells to promote hair growth, but its effectiveness is debated. Some users are skeptical, citing past failures of similar treatments and questioning the company's claims.
