What is the recommended storage condition for hair color products?

Storing hair color products at room temperature is recommended because it helps maintain their integrity and effectiveness. Room temperature provides a stable environment that prevents the chemical components of the hair color from degrading. Extreme temperatures, such as those found in a freezer, can cause the products to become ineffective or even spoil, while exposure to direct sunlight can lead to chemical breakdown and loss of potency. Additionally, a humid environment can encourage microbial growth and affect the overall quality of the products. Therefore, keeping hair color products at room temperature ensures their longevity and the desired results during application.
