I think washing with shampoo every day is too much, unless your scalp is very oily.  Perhaps you could try a CO, or conditioner only wash.  Basically, you're washing your scalp w/a light weight conditioner and then conditioning the length as usual.

Do you feel the wetting it on some days is giving you the result you want?  You can of course "wash" your scalp with water, using your fingers to remove any debris just like you would if you were using a shampoo.
