- Prohall does not publish a full INCI list for this product, so the label on the vial is the authoritative source.
- Never mix it in a metal bowl - use plastic or glass, as the brand instructs.
- The vial holds a single dose, so there is nothing left to store once it is opened and mixed.
Patauá oil carries the conditioning side with its lipids and omega-9, vegetable keratin gives the fibre something to hold on to after an alkaline service, and D-panthenol adds the humectant layer that oils alone do not cover. Diluted with water and left on for five minutes, the acidic base of the fluid is what brings the pH back down, while the three actives work on how the strand looks and feels once the cuticle closes again.

Learn moreMeet the Prohall Equalize Neutralizing Ampoule, the single-dose closing step of Prohall Professional's Equalize line — 0.51 fl oz (15 ml) of an acidifying, pH-balancing fluid made for hair that has just come out of a chemical service.
Its formula brings together patauá oil, vegetable keratin and D-panthenol to help bring the hair's pH back into balance, help neutralize leftover alkaline residue and leave the cuticle looking sealed, soft and aligned. In Brazil, where salon chemistry — from progressive smoothing to bleaching and colour — is part of everyday beauty culture, a neutralizing ampoule is the step professionals reach for before anything else goes on the hair.
A different product from the Equalize Neutralizing Shampoo. The shampoo is the line's acidifying cleanser for the wash step. This ampoule is the concentrated single-dose format — one sealed glass vial you mix with water and work through the lengths right after the service, so the fibre is prepared for the masks, leave-ins and hydration that follow.
Key Features:
- pH balance: An acidifying fluid that helps bring the hair's pH back to a balanced, comfortable range after alkaline services.
- Post-chemical step: Helps neutralize leftover chemical residue so the fibre is ready for what comes next.
- Cuticle sealing look: Helps the surface of the strand look sealed and smooth, with less visible frizz.
- Softness and shine: Patauá oil and D-panthenol help hair look hydrated and feel silky to the touch.
- Fibre support: Vegetable keratin helps support the look and feel of strands worn down by colouring and smoothing.
- Single-dose practicality: One sealed 0.51 fl oz (15 ml) glass vial, measured for a single application with no guesswork.
- Professional format: Developed by Prohall Professional for salon routines and for at-home users who follow them step by step.
How To Use
- Mix: In a non-metallic bowl, mix equal parts water and the contents of the ampoule until you get a smooth emulsion.
- Apply: Work the emulsion through clean, damp hair section by section, gloving each strand so it absorbs evenly.
- Rest and rinse: Leave on for 5 minutes, rinse thoroughly and finish as you prefer, with a mask or conditioner.
Expert Tip: Always use a plastic or glass bowl — never metal — and follow with the Equalize Neutralizing Shampoo when you want the full post-service routine of the line.
Ingredients (Highlights)
- Patauá Oil: An Amazonian oil the brand highlights for its lipid and omega-9 content, used here to help hair look deeply hydrated, glossy and pliable.
- Vegetable Keratin: A plant-derived keratin used in post-chemical care to help support the look and feel of the hair fibre.
- D-Panthenol: A well-known hair-care humectant that helps hair look more hydrated and feel more elastic and resistant to handling.

FAQ
What does a neutralizing ampoule do after a chemical service?
Chemical services such as relaxing, smoothing, bleaching or colouring leave hair in an alkaline state with the cuticle open. An acidifying ampoule like this one helps bring the pH back into balance and helps remove leftover residue, so the fibre looks sealed and is ready for the masks and leave-ins that follow.
How is it different from the Equalize Neutralizing Shampoo?
They are two products from the same line. The shampoo is the acidifying cleanser you use in the wash step. The ampoule is a concentrated single-dose fluid, mixed with water and applied strand by strand as the finishing step of the service.
Which hair types is it for?
All hair types, and especially hair that is chemically processed, fragile or dry-looking after a service. It is a rinse-out cosmetic product for external use on the hair.
Is the product authentic, and why is the label in Portuguese?
Yes. Every unit is genuine Prohall Professional stock sourced in Brazil and shipped sealed in its original packaging, which is why the glass vial and carton are printed in Portuguese and read 15 ml / 0.50 fl oz. The English details you need are all on this page.
Do you ship internationally?
Yes, MKPBR offers worldwide shipping with reliable tracking and a clear returns policy.
