Protein vs moisture for hair: what changes the choice?
Choose from how hair behaves, not a fixed calendar. Stiffness and tangling can signal a poor fit; limp or weak-feeling hair may need a different balance.
A careful way to test this
Keep the rest of the routine stable, follow current labels, and change one variable at a time. Stop if discomfort is persistent or severe.
What the label can tell you
Check ingredients, directions, warnings, and intended use. Formula and claims can change, so the current package is the source of truth.
