how to use

To use the Olaplex No.5 Scalp Longevity Treatment, start by parting your hair into sections using the precision nozzle. Apply the treatment directly onto the scalp, gently squeezing the bottle as you go. Focus on 3–4 key areas around the crown and back of the head. Massage the product into your scalp thoroughly to support absorption and circulation. You can apply it to dry hair before bed as an overnight scalp treatment, or use it before styling wet hair. It’s ideal for use 3 times per week, but gentle enough for daily application if desired.
