When applying hair treatments, it's particularly important to avoid using them on damaged hair. Damaged hair is often more brittle, porous, and weaker than healthy hair, which makes it less able to withstand additional chemical processes or treatments. Applying damage-inducing products to hair that is already compromised can exacerbate the existing issues, leading to further breakage, split ends, and irreversible damage.

In contrast, while dry hair may benefit from certain treatments to restore moisture, and colored hair can often handle a variety of treatments as long as they are suitable for chemically treated hair, damaged hair requires special consideration. Treatments should be tailored to repair or strengthen hair instead of further compromising its integrity. Greasy hair, while needing cleansing, is not as critical of a condition as damaged hair when it comes to the application of reparative or rejuvenating treatments.
