Help me be a mad scientist with my shampoo!

Calling all chemists and haircare junkies: is it possible to add salicylic acid and/or ketoconazole into a shampoo, rather than buying off-the-shelf shampoos with these ingredients in them? If so, how do I do this? If not how do I prevent over-washed and dried out hair?

I have dandruff and other scalp issues, and through a long process of trial and error, I have discovered that all of this is best managed through washing my hair first with a shampoo containing 1% or 2% ketoconazole (Nizoral), and then with a 3% salicylic acid shampoo (the CVS generic version of Neutrogena T-Sal, to which I have added tea tree essential oil and lavender essential oil). I do this probably three times a week
So far, so good, right? Unfortunately, while all of this keeps my scalp issues totally under control, it's really drying out the length of my hair (a bit past shoulder length at the moment). My hair is fine in texture (each strand is), but reasonably thick (as in, I have a fairly large amount of it), and wavy/curly. After each shower, the length of my hair is dry, frizzy, poufy, and generally unmanageable for at least a day, until it gets some of its natural oil back. But by that point, my scalp needs to be washed again. I've tried just concentrating the shampooing on my scalp (and putting conditioner on the length), which has been somewhat successful, but some shampoo still gets on my length and dries it out. Conditioning after the two shampoos helps a bit, as does a leave-in protein conditioner (Terax life drops), but it's still dry and fluffy. (Too much conditioner makes my hair limp and stringy because of its fineness, so I'm loath to add too much more.)
What I would like to do is to move to shampooing only once rather than twice. Is it possible to use either the Nizoral as a base and add in salicylic acid, or to use the T-Sal generic as a base and add in ketoconazole? Can the non-chemist layperson buy these ingredients in powders (?) anywhere? If so, how would I know how much to add to a six ounce bottle of shampoo to get the right concentrations? And would they dissolve in the shampoo at room temperature if I just add it to the bottle? The ideal for me would be to buy a much gentler shampoo and add both salicylic acid and ketoconazole to it, but I would be happy to use one of the existing ones as a base if that won't work. Help?
