"i do it (right after each other, and i alternate between which one goes on first) and i have fine results. if you use the generic minoxidil that's oily (I use dr. lee's) you probably would want to put tricomin on first." -ADogg from hairlosshelp
"I highly recommend Tricomin!!! My hair feels great is thicker and I think it helps Minoxidil work better. I use the shampoo and conditioner then the spray right before blow drying my hair." -Tricomin testimonial
I guess you can use it together... I personally wouldn't feel comfortable doing that if I was using those 2 treatments.
