Why should hair extensions be washed in lukewarm water?

Washing hair extensions in lukewarm water is crucial for reducing the risk of shrinkage and maintaining hair quality. Lukewarm water is gentle enough to cleanse the extensions without causing the hair fibers to contract or become damaged. Hot water can strip the natural oils from the hair, leading to dryness, breakage, and overall deterioration of hair quality. Similarly, cold water may not effectively remove dirt and product buildup, compromising the cleanliness and appearance of the extensions. By washing in lukewarm water, you strike a balance that helps preserve the integrity and longevity of the hair extensions, ensuring they remain soft, manageable, and looking their best for an extended period.
