How to Use:
Start with thoroughly wet hair. Apply a small amount of Olaplex No.4P Blonde Enhancer Toning Shampoo and distribute evenly between your palms, then work through the hair from roots to ends. Lather fully and allow the shampoo to sit for 1–3 minutes before rinsing well. For a stronger toning effect, leave on for up to 5 minutes, then rinse and follow with a conditioner or mask.

Frequency:
Use weekly or as needed, according to how often your hair requires toning and the guidance on the packaging.

Application Technique:
Focus the product where brassiness is most visible, ensuring even coverage. Massage gently into the scalp and lengths, then rinse thoroughly until the water runs clear.

Best Practices:
Use on clean, wet hair and follow with a hydrating conditioner to keep hair feeling soft. Adjust leave-on time to suit your desired level of coolness. Patch test if you have a sensitive scalp and avoid overuse to maintain balance in your routine.

Safety Tips:
Avoid contact with eyes; if this occurs, rinse immediately. Discontinue use if irritation occurs and keep out of reach of children. Use externally only and follow any additional instructions on the product packaging.
