Here are some links that get you started.
The first one mentions amino-acids and citric acid, together with sodium citrate as a buffering agent. Ascorbic acid (vitamin-C) is mentioned in the second link. I have not found alkalis unless the -OH radical in the alcohol class of organic substances counts, or if the alkalinity resulting from the hydrolysis of certain salts counts.

"I have not found alkalis unless the -OH radical in the alcohol class of organic substances counts."
No it doesn't, the organic -OH group is very different from an inorganic OH^- ion.
Most shampoos have a pH in the 5-6.5 range and so are slightly acidic. Others that are soap based are alkaline because the soap used is the salt of a weak acid and a strong base.
