Just wetting the hair adds moisture (= water), hair feeling dry doesn't necessarily mean it needs more water - it can be build of a product ingredient, build up of minerals from hard water, raised cuticle due to damage, raised cuticle due to alkaline products. Hair that is overly 'moisturised' or kept wet for long periods can get weaker due to the water breaking some of the structural protein bonds, also swelling the cuticle (hygral fatigue).
I am deep conditioning less and less often of late and I don't notice any detrimental effects to my porous colour treated hair. I do deep treatments (primarily coconut oil on dry unwashed hair as per the research), I also use a very gentle cleansing method (co-wash) and a leave in conditioner so in a way my hair is getting an intensive conditioning every time I wash.
