When in my routine should I apply it — after washing, before heat styling, or during the day? — "Dr.S Keratin" Spray, 150 ml

The spray works at several points in a routine. After washing, apply to towel-dried lengths before blow-drying to help the hair comb through more easily and reduce snagging. Before using flat irons, curling wands, or other hot tools, a light layer on dry hair can make the surface smoother so the tool glides with less friction. During the day, if the ends start to look dry or flyaway — especially in humid weather or heated indoor air — a quick mist on the lengths can restore a neater finish without a full wash. Because it is a leave-in product, there is no need to rinse it out. Store the bottle at room temperature, away from direct sunlight, and keep the nozzle clean so the spray stays fine and even.
