You don't list you hair properties but mayo is extremely oily and heavy. I think you'd be better off getting a treatment packet from Sally's for $2 or so. Depending on your properties, you may need a moisturizing treatment following a PT. also, most protein can't enter the hair shaft, it fills in holes in the cuticle from the outside, so clarifying after is probably just going to wash it all off. I always clarify before a PT and my fine hair pretty much never needs a DT after.

Baking soda and ACV should be fine for most people if used correctly and only occasionally. Both do have the potential to be harsh.
