Are folligen/tricomin supplemental products necessary (condition/shampoo/oil ect.)?

[ch4545]

For slow dispersed thinning, what are best products. I'm looking to order some folligen right now, or tricomin. I've read the comparison on both and figured I'd go folligen. But should I get the shampoo and oil ect? Or just buy nizoral? Is there anything else I should look into? Like the revivogen? I think I'm a Norwood 1 or 2, I'm 28 and it's been slowly thinning since I was almost 20. I think it amped up this last year due to age but also insane amounts of nicotine use and stress. I'll post pictures in a bit if necessary.
