In what order do u apply your hair products after u wash and condition? I do spray leave-in,cream leave in, serum/oil, other styling products (if any).
One thing I know is, if you're going to apply a serum, it should come AFTER the moisturizers, coz it creates a seal/coating that'd prevent moisturizers from reaching your hair.
For me, order does matter. It depends on what I'm using for that day. Generally, moisturizers always go on first and any oils and/or gels goes on last.
