The conditioning, hydrating, regrowth, and repair treatments you receive at the salon are typically very concentrated, thus- they work quick and efficiently. At-home treatments need to sit on the hair much longer than salon treatments. Before you get in the shower, apply a treatment to dry hair. Think of your hair as a sponge; it can absorb more water if it starts out dry than if it were already wet. Besides, we rarely leave treatments on for the appropriate amount of time when we are in the shower anyways. Putting the product on your dry hair beforehand is a guaranteed way to make sure you’re reaping the full benefits of your at-home treatment.
