| 摘要 |
Embodiments of the invention relate to a composition, method and kit for producing galvanic cells upon application of the composition to the skin. In some embodiments, the composition comprises encapsulated half-galvanic cell units (e.g. individual and/or autonomous half-galvanic cell units) having the same ox/red potential (Eº), wherein each half-galvanic cell unit comprises metal particles in the range of nano- to micro size or a mixture thereof, suspended within an aqueous solution of soluble electrolytic salt of same metal and wherein each half-galvanic cell unit is encapsulated by internal layer(s) made of hydrophilic metal (including silicon) oxide nanoparticles and external layer(s) made of hydrophobic metal (including silicon) oxide nanoparticles. The composition is useful for preventing and/or treating alopecia or for enhancing hair growth). |
