What is an important consideration when choosing hair products for colored hair?

When selecting hair products for colored hair, one of the most significant considerations is the alcohol content. Many alcohols can be drying or damaging to hair, especially when it's been color-treated. Color-treated hair often requires special care to maintain moisture and vibrancy, and high alcohol content in hair products can strip the hair of essential moisture and lead to color fading more quickly.

Products with lower alcohol levels are typically recommended for colored hair as they help preserve the integrity of the hair color while maintaining hydration. This helps in extending the lifespan of the color and improves the overall health of the hair.

While factors such as fragrance strength, protein level, and water content are also important, the impact of alcohol content on hair's moisture retention and color longevity makes it a critical factor when choosing appropriate products for colored hair.
