Greetings, Please correct me if I'm wrong about any of this but... If I understand this porosity thing correctly, it involves the degree to which your hair absorbs and releases moisture. This is apparently related to the degree of openness of the cuticles (more open = more absorption/loss). The degree of cuticle opening depends upon pH (acidic = closed cuticle, basic = opened cuticle) ... Presuming that that is all correct, would it be useful/logical to do some variation of the following every week? 1) Wash hair (diluted shampoo = to get out built up product) 2) Baking soda wash (high pH/basic = pore/cuticle opening in order to absorb DC) 3) Apply DC (let it seep into the wide open pores/cuticles = deep penetration) 4) ACV rinse (low pH/acidic = pore/cuticle closing/sealing in order to seal in the benefits of the DC) **Note: I am presuming that ACV is acidic. But a Google search didn't really give a clear answer. Any insight on that would be appreciated too. Thanks. PS - If the above line of thought is correct, then wouldn't using baking soda to open cuticles/increase absorption minimize the need to sit under heat during the DC?
