Chemical labeling is the primary line of defense against accidental misuse, improper mixing, and incorrect storage of salon chemicals. A label communicates what a substance is, what hazards it presents, and how it should be handled, all in the seconds it takes to glance at a container before picking it up. In a busy salon where dozens of different chemical products are stored, mixed, and applied throughout the day, the labeling system must be comprehensive enough to convey essential safety information yet simple enough that staff actually read and follow it. When labeling fails, whether through missing labels, illegible labels, or labels that have been removed or obscured, the person handling the container loses the information they need to handle it safely. This guide covers how to implement and maintain a chemical labeling system that keeps every product in your salon correctly identified from the moment it arrives until the moment its empty container is disposed of.
Chemical products arrive at the salon with manufacturer labels that comply with regulatory requirements and provide comprehensive hazard information. However, from the moment the product enters the salon, these labels begin to deteriorate. Liquid chemicals splash onto labels during dispensing, making them illegible. Labels on frequently handled containers wear from contact with gloved hands. Products transferred to smaller working containers during mixing may receive handwritten labels that fade, smear, or fall off. Products stored in areas with heat or humidity may have labels that peel or discolor. Over time, the salon may contain containers where the label is partially readable, containers where the label has been replaced by a strip of tape with a product name written in marker, and containers with no identification at all.
The consequences of inadequate labeling extend beyond regulatory non-compliance. A container of developer that looks identical to a container of conditioner when the labels are missing can lead to a serious chemical error during a service. A cleaning product stored in an unlabeled spray bottle cannot be identified by the next person who picks it up, and they cannot determine what hazards it presents or what personal protective equipment they should wear. An unlabeled container of mixed product left at a workstation could be used by another stylist who does not know what it contains, at what concentration it was mixed, or how long ago it was prepared.
Hazard communication regulations require that chemical containers in the workplace bear labels that identify the product and communicate its hazards. Original manufacturer containers must retain their original labels with all required information intact. When chemicals are transferred to secondary containers for workplace use, those containers must also be labeled with at least the product identity and the relevant hazard warnings. Some jurisdictions require that workplace labels include the same elements as manufacturer labels: product name, hazard pictograms, signal words, hazard statements, and precautionary statements. Others allow simplified workplace labels that reference the Safety Data Sheet for complete information. Regardless of the specific format required, the fundamental requirement is that every container of chemical product in the salon must be identifiable.

Walk through every area of the salon where chemicals are stored, mixed, or used, and evaluate the labeling status of every chemical container. Check the main storage area, individual workstation drawers and shelves, the mixing station, the shampoo bowl area, the dispensing system, the cleaning supply storage, and any other location where chemical products are kept. For each container, determine whether it has a label, whether the label is legible, whether the label accurately identifies the contents, and whether the label includes hazard information. Document every container that has a missing, damaged, illegible, or inaccurate label. This audit reveals the current state of labeling in your salon and identifies the locations and situations where labeling failures are most common.
Step 2: Establish Standards for Original Container Labels
Set a standard that original manufacturer labels must be maintained in legible condition for as long as the product remains in the salon. Implement practices that protect original labels from damage. Store products with labels facing outward so they can be read without handling. Use drip trays or containment systems to prevent chemical splashes from contacting labels on adjacent containers. Replace containers that have damaged labels by transferring the product to a clean container with a new manufacturer label, or by applying a replacement label that contains all the original information. Dispose of products whose manufacturer labels are too damaged to read if replacement labels cannot be accurately produced, because an unidentifiable chemical product is a safety hazard that should not remain in the salon.
Step 3: Design a Secondary Labeling System
Create a standardized labeling system for all containers that hold products transferred from their original packaging. This includes mixing bowls, application bottles, spray bottles, dispensing containers, and any other vessel used to hold salon chemicals. The secondary label should include the product name as it appears on the manufacturer's label, the key hazard warnings applicable to the product, the date the product was transferred or mixed, the name or initials of the person who prepared it, and any time limitations on use such as discard-by times for mixed products. Standardize the label format across the salon so that all secondary labels have the same layout, making them easy to read and interpret regardless of which staff member created them.
Step 4: Use Color Coding to Supplement Written Labels
Implement a color coding system that provides immediate visual identification of chemical categories at a glance, supplementing the detailed information on written labels. Assign distinct colors to major chemical categories: one color for oxidizers, another for alkaline products, another for cleaning chemicals, another for disinfectants, and so on. Apply the color coding through colored labels, colored tape on containers, or colored storage bins. The color system does not replace written labels but provides an additional layer of identification that helps staff quickly distinguish between chemical categories, reduces the risk of picking up the wrong container, and supports proper storage by making it visually obvious when a container is stored in the wrong location.
Step 5: Label Chemical Storage Locations
In addition to labeling individual containers, label the storage locations themselves. Shelves, cabinets, and storage areas should be marked with the chemical categories that belong in each location. This location labeling serves two purposes. First, it guides staff to store products in the correct location after use, maintaining the organization system that keeps incompatible chemicals separated. Second, it provides a cross-reference that helps identify a container even if its own label is partially damaged, because the storage location provides context about what type of product the container should contain. Label storage locations with both the chemical category and any relevant safety information, such as ventilation requirements or incompatible products that must not be stored in the same area.
Step 6: Implement Labeling Rules for Mixed Products
Establish and enforce rules for labeling products that are mixed in the salon. Every container of mixed product must be labeled immediately upon mixing, before it is carried to a workstation or used on a client. The label must identify the products that were mixed, the mixing ratio or concentration, the time of mixing, and the expiration time after which the mixed product should be discarded. Mixed products that are left unlabeled create a particularly dangerous situation because they may contain active chemicals at concentrations that cannot be determined by looking at the container. A strict rule that no mixed product may exist in an unlabeled container, even briefly, prevents the accumulation of unidentified chemical mixtures at workstations.
Step 7: Conduct Regular Label Maintenance Inspections
Schedule regular inspections of all chemical labels throughout the salon. Weekly inspections during routine cleaning are practical for most salons. During each inspection, check that all containers have legible labels, that secondary labels on working containers are current and accurate, that mixed product containers from previous days have been properly disposed of, that storage location labels are intact and visible, and that any new products added since the last inspection have been integrated into the labeling system. Replace any label that is fading, peeling, stained, or otherwise becoming difficult to read. Consistent label maintenance prevents the gradual deterioration that turns a well-labeled salon into one where unlabeled containers accumulate over time.
At minimum, a secondary container label must include the identity of the chemical product so that anyone handling the container can determine what it contains and can locate the corresponding Safety Data Sheet for detailed hazard and handling information. Many jurisdictions require additional information on secondary labels including hazard warnings, pictograms, or signal words. Best practice for salon secondary labels goes beyond the regulatory minimum to include the product name, the manufacturer name, the primary hazards, the date of transfer or mixing, the preparer's name or initials, and any use-by or discard-by time. The more information the label provides, the less the handler needs to reference the Safety Data Sheet for routine handling decisions. However, the label must be readable at a glance, so prioritize the most critical information rather than trying to replicate the entire Safety Data Sheet on a small container.
Products applied directly to clients during salon services must be identifiable at the point of use so that the stylist knows exactly what they are applying, so that the Safety Data Sheet can be immediately accessed if a reaction occurs, and so that the service record can accurately document which products were used. If a product is transferred from its original container to an application bottle or bowl, that application container must be labeled before it reaches the service area. The practice of mixing products into unlabeled bowls and carrying them to the workstation creates a traceability gap. If the client has a reaction, the unlabeled bowl may have been rinsed before the specific product can be confirmed, complicating the response. Maintaining labeling through the point of application supports both client safety and accurate service documentation.
If a salon uses products with manufacturer labels in a language that some or all staff members cannot read, the salon must ensure that the hazard information is accessible in a language the staff understand. Options include applying supplementary labels in the staff's working language that contain the product name, key hazards, and handling instructions, or maintaining a reference document at the storage and mixing locations that provides translated information for each product. The Safety Data Sheet, which must be available for every product and is often available in multiple languages from the manufacturer, is the authoritative source for this translated information. Simply having an unreadable label on a container does not satisfy the requirement that workers can identify the products they handle and understand their hazards.
