No, it is my own recipe. I wouldn’t call it a recipe though, it’s just mixing coffee with castile soap, 2 ingredients in total.
Here’s what inspired in the first place, actual studies proving caffeine and its effect on hair growth or preventing hair loss.

-increase hair follicle stimulation
-prolong anagen phase
-upregulated IGF-1 gene expression (whatever that means)
