OLAPLEX - Nº. 0.5 Scalp Longevity Treatment

The Nº. 0.5 Scalp Longevity Treatment from OLAPLEX is a scalp treatment for the scalp, in serum form. Suitable for all hair types, particularly for a sensitive scalp. The formula combines Bond Building Technology with antioxidants and fatty acids. That contributes to a healthy microbiome: the bacteria and fungi that naturally live on the skin. It also helps balance the pH, the acidity of the scalp.

Who is the OLAPLEX Nº. 0.5 Scalp Longevity Treatment suitable for?

Straight, wavy, curly or coily hair: the OLAPLEX Nº. 0.5 Scalp Longevity Treatment suits every hair type. Nº. 0.5 targets the scalp itself, not the hair fibre, so it suits anyone who wants to improve the condition of the scalp. If you have a sensitive scalp, this scalp serum is made for that: it hydrates, soothes and helps strengthen the scalp barrier. Even without specific concerns, you can use the serum as a basic step in your hair routine.

How do you use the OLAPLEX Nº. 0.5 Scalp Longevity Treatment?

Part your hair into sections with the included needle applicator and apply the serum directly to the scalp. Work through all sections of the scalp this way and massage the serum in well. Use the Scalp Longevity Treatment on wet hair before styling, or as an overnight treatment on dry hair. Apply the serum three times a week for the best result; the formula is mild enough for daily use.

What's the difference between Nº. 0.5 and the other OLAPLEX numbers?

OLAPLEX Nº. 0.5 Scalp Longevity Treatment is the only product in the Nº. range that you apply to the scalp. Nº. 0 Intensive Bond Building Treatment works the other way round and leaves the scalp alone. You use that pre-treatment on dry hair, applied from mid-lengths to ends.

The other numbers are made for the hair fibre, not the scalp. Think of Nº. 3 Hair Perfector and the shampoos, conditioners and styling products from Nº. 4 through Nº. 10. If you want to care for both scalp and hair, combine Nº. 0.5 with one of those products in your regular wash routine.

Ingredient highlights

Bis-Aminopropyl Diglycol Dimaleate. The brand's own molecule behind OLAPLEX's Bond Building Technology, used throughout the whole Nº. range. According to OLAPLEX, the technology in this product re-links the disulfide bonds in keratin. That strengthens the stratum corneum: the outermost layer of the scalp barrier.

Glycine Soja (Soybean) Seed Extract. An extract from the seeds of the soybean.

Ceramide NP, Ceramide AP and Ceramide EOP. Three forms of ceramide, a fat-like substance that naturally occurs in the skin barrier.

Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Sodium Hyaluronate Crosspolymer and Hydrolyzed Sodium Hyaluronate. Four forms of hyaluronic acid, a substance that naturally occurs in the body.

Tasmannia Lanceolata Leaf Extract. An extract from the leaf of the Tasmanian pepper plant (Tasmannia lanceolata).

Phytosphingosine. A lipid that naturally occurs in the skin.
