Salons provide ideal conditions for mold growth. Moisture from shampoo stations, steam from hot water use, humidity from multiple wet heads of hair drying simultaneously, and condensation on surfaces in poorly ventilated areas create persistent damp conditions that mold requires to colonize. Once established, mold releases spores into the air that staff and clients inhale throughout the day. Mold exposure causes respiratory irritation, allergic reactions, and in immunocompromised individuals, serious infections. Training staff to identify mold, understand its health effects, and implement moisture control practices prevents mold from establishing in the salon environment.
Mold does not require flooding or visible water damage to grow. It requires only a surface with organic material, moisture above 60 percent relative humidity, and time. In salons, these conditions exist in locations that staff may not regularly inspect. Behind shampoo bowls where water splashes against walls. Under floor mats that trap moisture between the mat and the floor surface. Inside HVAC ducts where condensation provides both moisture and a dust nutrient source. On ceiling tiles above steam-generating areas. In storage rooms with poor ventilation where damp towels or cleaning supplies create localized humidity.
Mold colonies often grow for weeks or months before becoming visible. The first indication may be a musty odor that staff become accustomed to and stop noticing. By the time visible mold appears on a surface, the colony has penetrated the substrate material and is releasing spores into the air. Mold that grows behind walls, under flooring, or inside ductwork may never become visible but can release significant quantities of spores into the occupied space.
The health effects of mold exposure are particularly relevant in salons because staff are present for eight or more hours per day, accumulating far greater exposure than clients who visit for one to two hours. Staff with pre-existing asthma or allergies are especially vulnerable to mold-triggered respiratory symptoms. Some mold species produce mycotoxins that cause symptoms beyond simple allergic responses, including headache, fatigue, and neurological effects.
OSHA does not have a specific mold exposure standard, but the general duty clause requires employers to address recognized hazards including mold contamination that affects worker health.
OSHA has published guidance on mold in the workplace recommending prompt identification and remediation of mold growth, correction of moisture problems that allow mold to grow, and protection of workers during mold remediation.
EPA provides extensive guidance on mold prevention and remediation in commercial buildings, including the recommendation that indoor relative humidity be maintained below 60 percent and ideally between 30 and 50 percent to prevent mold growth.
State and local health departments may have regulations regarding mold in commercial spaces, and some states require mold remediation to be performed by licensed professionals when contaminated areas exceed specified sizes.
Building codes require adequate ventilation in commercial spaces, and inadequate ventilation that leads to moisture accumulation and mold growth may constitute a building code violation.
Check your salon's hygiene score instantly with our free assessment tool →
Mold awareness reflects the environmental hygiene that the MmowW assessment evaluates.
Walk through your salon and check behind shampoo bowls, under floor mats, around window frames, and on ceiling tiles for visible mold or discoloration. Notice whether there is a musty or earthy odor in any area. Check the humidity level with an inexpensive hygrometer. If relative humidity consistently exceeds 60 percent, mold growth conditions exist.

Identify and address every moisture source in the salon. Repair plumbing leaks at shampoo bowls, sinks, and water supply lines immediately when discovered. Ensure that shampoo bowl drains flow freely and do not back up. Install splash guards behind shampoo bowls to prevent water from contacting wall surfaces. Wipe up standing water on floors, counters, and around sinks promptly. Ensure that wet towels are placed in ventilated laundry bins rather than piled in closed containers where moisture is trapped. Run exhaust fans in restrooms and any enclosed area where water is used. Address roof leaks, window condensation, and exterior wall moisture penetration promptly.
Step 2: Maintain Proper Humidity Levels
Monitor indoor humidity levels with hygrometers placed in the shampoo area, main salon floor, and any area prone to moisture accumulation. Maintain relative humidity between 30 and 50 percent. Use the HVAC system's dehumidification function during humid weather. Supplement with standalone dehumidifiers in areas where the HVAC system cannot maintain adequate humidity control, such as shampoo rooms or basement-level salon spaces. Ensure that the HVAC system's condensation drain lines are clear and flowing, as blocked drain lines cause condensation to back up into the duct system, creating mold growth conditions inside the ducts. Ventilate moisture-generating activities by running exhaust fans during and after peak shampoo and wet-styling periods.
Step 3: Inspect for Mold Regularly
Conduct monthly visual inspections of mold-prone areas. Check behind and under shampoo bowls, around plumbing fixtures, under floor mats and rugs, around window frames and sills, on ceiling tiles especially above moisture-generating areas, in storage rooms and closets, and around HVAC vents and returns. Look for visible mold growth, which may appear as dark spots, fuzzy growth, or discoloration on surfaces. Check for water stains that indicate current or past moisture intrusion. Note any musty odors, which may indicate hidden mold growth behind walls or in concealed spaces. Document findings and address any mold or moisture issues immediately.
Step 4: Remediate Small Mold Problems Promptly
Small areas of mold growth on non-porous surfaces, typically less than 10 square feet, can be cleaned by salon staff using appropriate precautions. Wear an N95 respirator, rubber gloves, and eye protection during cleaning. Clean the mold with a solution of detergent and water, scrubbing the surface to remove all visible mold. Do not use bleach alone, as bleach kills surface mold but does not remove the organic material that mold feeds on, allowing regrowth. After cleaning, dry the area thoroughly and address the moisture source that allowed the mold to grow. For mold on porous materials such as ceiling tiles, drywall, or carpet, removal and replacement of the affected material is typically necessary because mold penetrates into porous substrates and cannot be fully removed by surface cleaning.
Step 5: Engage Professionals for Significant Mold
When mold contamination exceeds 10 square feet, when mold is present in HVAC systems, when mold growth recurs despite remediation, or when staff report health symptoms potentially related to mold exposure, engage a professional mold remediation company. Professional remediation includes containment of the affected area to prevent spore spread, HEPA-filtered air scrubbing during removal, removal of contaminated materials, treatment of structural surfaces, and verification testing after remediation. Do not allow staff to work in areas undergoing mold remediation. Provide temporary relocation of affected workstations until remediation is complete and clearance testing confirms that airborne mold spore levels have returned to acceptable concentrations.
Step 6: Train Staff on Mold Reporting and Health Effects
Train all staff to report any suspected mold growth, musty odors, or water intrusion to management immediately rather than ignoring or attempting to address it themselves. Explain the health effects of mold exposure so that staff understand why prompt reporting and remediation are important. Respiratory symptoms including nasal congestion, sneezing, cough, wheezing, and throat irritation may be caused or worsened by mold exposure. Allergic reactions including skin rash, eye irritation, and asthma attacks can be triggered by mold spores. Staff who develop new or worsening respiratory symptoms that improve on days away from work and worsen when returning should report this pattern, as it may indicate an environmental trigger including mold.
Yes. Any equipment that involves water or moisture can harbor mold growth. Shampoo bowls with inadequate drainage or splash containment create moist environments on surrounding surfaces. Towel warmers that are not emptied and cleaned regularly can develop mold on interior surfaces. Humidifiers and steamers that are not cleaned and dried between uses grow mold on internal components. HVAC components including drain pans, cooling coils, and ductwork accumulate moisture that supports mold growth. Even seemingly dry equipment like styling chairs can develop mold on the underside of cushions if moisture is trapped between the cushion material and the chair frame. Regular cleaning and drying of all equipment that contacts water, combined with inspection of equipment interiors during routine maintenance, prevents mold colonization.
A musty smell indicates the presence of microbial volatile organic compounds produced by mold and bacteria growing on damp organic material. The odor itself is produced by chemical compounds including aldehydes, ketones, and terpenes that can cause respiratory irritation at sufficient concentrations. More importantly, the musty odor indicates active mold growth that is releasing spores into the air. The spores are the primary health concern because they carry allergenic proteins and, in some species, mycotoxins. A salon with a persistent musty odor has a mold problem that requires investigation and remediation regardless of whether visible mold has been found. The odor may originate from concealed mold growth behind walls, under flooring, or inside ductwork that is not visible during routine inspection.
Mold can begin to grow within 24 to 48 hours after a water incident on organic materials such as drywall, ceiling tiles, carpet, and wood. Within one week, mold colonies can become established and begin producing spores. This rapid timeline means that any water intrusion, plumbing leak, or flooding event must be addressed immediately with thorough drying of all affected materials. Materials that cannot be dried within 48 hours should be removed and replaced. Using commercial dehumidifiers and fans to accelerate drying after a water event is critical. If a shampoo bowl overflows, a pipe leaks, or flooding occurs from any source, the 48-hour window for preventing mold growth begins immediately and should drive the urgency of the response.
