I think reconstructors are "mild protein treatments". Mild because they have moisturizing properties in addition to the protein instead of being just pure protein. So perhaps that's the difference. Good leave-in moisturizers have water listed as one of the first ingredients and so probably the same would apply with a moisturizing protein conditioner aka mild protein conditioner. I don't know if there's a way to find out for sure if a product is OK to use without trying it or hearing reviews from those who have, especially if it says it's OK for daily use. Everyone's hair responds differently. Many pple use Infusium leave-in with great success while others experience breakage due to the protein in it that leads to hard, brittle hair. So if the instructions say it's for daily use and you're not experiencing hardness in your hair due to too much protein, then I'd say it's OK to use daily. I'd only change a regimen if I were having problems with a product or procedure.
