I am running low on my oil spray this week (the one by Carolyn Gray). While I am awaiting my new bottle, I have been trying to conserve the little I have left by moisturizing my hair only in the mornings, instead of doing so both morning and nights. Surprisingly, my hair seems smoother and softer since I started doing this. I'm trying to figure out whether I've been overmoisturizing my hair (I haven't had any adverse effects yet). Does such a thing exist?
