Storing chemicals in a cool, dry place, away from direct sunlight is crucial for several reasons. Many chemicals used in salons, such as hair dyes, perm solutions, and other products, can be prone to degradation or unpredictable chemical reactions when exposed to heat, humidity, or direct sunlight. Heat can cause chemicals to break down, leading to reduced efficacy or even hazardous reactions.

Keeping chemicals in a dry environment also helps prevent moisture from affecting their stability. Sunlight can alter the chemical composition of certain substances, rendering them ineffective or unsafe for use on hair or skin. Therefore, maintaining a stable environment that protects these products will ensure their longevity and effectiveness, making it essential for salon operations.

While storing in a locked cabinet is a good practice for safety and security, the storage conditions themselves (temperature and light exposure) are even more critical for the integrity of the chemicals. Similarly, keeping chemicals in a bathroom or on the salon floor poses risks of temperature fluctuations and exposure to moisture or contaminants, which could compromise the products.
