TLDR Minoxidil nanocrystals improved hair growth in mice more effectively and safely than regular Minoxidil.
The study aimed to enhance the bioactivity and water solubility of Minoxidil (MXD), a common hair growth stimulator, by creating nanocrystal structures (MXD-NPs) and testing their effect on C57BL/6 mice. The MXD-NPs were prepared using a bead mill and ultrasonic process and were characterized using various techniques. The cytotoxicity of MXD-NPs was tested on human dermal fibroblast (HDF) cells. The results showed that the MXD-NPs significantly increased the hair growth rate in C57BL/6 mice by targeting pilosebaceous follicles more effectively than regular MXD. The mice treated with MXD-NPs showed a higher rate of anagen/telogen follicular growth compared to those treated with MXD, indicating improved hair regrowth and follicular stimulation. This suggests that MXD-NPs could potentially replace the commercial solution format of MXD as a safer and more efficient structure.
