I just started using Tricomin at nights, followed a bit of Emu oil mixed with some other oils such as Lavender, Tea Tree, Rosemary and liquid Saw Palmetto . Haven't used it long enough to make any conclusions yet, but I feel positive about the chances of growth.
From research, both Tricomin and Folligen do the same thing with the Copper peptides. Folligen comes in cream/lotion form, so if you prefer that mode of application, then folligen is for you. Tricomin was just easier for me to get a hold of in Australia. Also, if you get the spray, do not use the spray but apply it with a dropper, to ensure you don't waste so much of the product on your hair.
