Storing chemical products in a cool, dark place away from direct sunlight is essential for maintaining the efficacy and safety of these products. Many chemical formulations are sensitive to light and temperature; exposure can lead to degradation, reducing their effectiveness and potentially altering their chemical composition. For instance, some products may oxidize or change state when exposed to heat or UV light, which could also lead to unwanted reactions or reduced shelf life.

While a locked cabinet is important for safety and preventing unauthorized access, storing products in a cool and dark environment directly addresses the preservation of the chemicals' integrity. Keeping them at stable temperatures and shielding them from light ensures that they can perform as intended during use, providing consistent results for clients and safeguarding the health of both clients and salon staff.

Storing products in a refrigerator might be suitable for certain items, but not all chemical products require refrigeration and may even be adversely affected by moisture. Placing products on a shelf above eye level poses safety risks; it may make access difficult and increase the likelihood of spilled or dropped containers.
