What type of hair products should clients avoid after getting extensions?

Clients should avoid products with alcohol or sulfate after getting hair extensions because these ingredients can be harsh and damaging to both the extensions and natural hair. Alcohol often dries out hair, leading to brittleness and breakage, while sulfates can strip away natural oils, resulting in dryness and a lack of moisture. Since hair extensions rely on the natural moisture of the hair and scalp for longevity and health, using products that contain these ingredients can negatively impact their appearance and lifespan. This is why it is essential for clients to choose gentle, nourishing products that promote hydration and maintain the integrity of their extensions.
