Prohall Blue and White Ultra Lightening Bleaching Powder – Dust-Free, Up to 9 Levels – 17.64 oz (500 g)

Key Features:

• Up to 9 levels of lift: A high-performance stabilized formula built for every lightening and bleaching technique in the salon.
• Dust-Free technology: The powder clumps instead of clouding when it meets the developer, so there is far less dust in the air around the bowl.
• Blue shade — anti-yellow: An anti-yellow pigment helps counter the look of warm undertones for a more even, cooler blonde.
• White shade — maximum lift: The neutral option when you want a clean, uniform canvas before toning.
• Hydrolyzed Collagen: Helps hair keep its natural-looking elasticity through the lightening service.
• Lightly fragranced: Noticeably less of the sharp chemical smell associated with bleaching powders.
• Smooth, even mix: Blends homogeneously with developer for precise, controlled application.
• Generous 17.64 oz (500 g) tub: Prohall states a tub covers roughly three months of medium to long hair work.

How To Use

1. Glove up: Put on gloves, protect the clothing and work in a well-ventilated space.
2. Mix: Combine the powder with a hydrogen peroxide developer — sold separately — at the ratio your technique calls for, and stir to a smooth paste.
3. Apply: Brush onto dry, unwashed hair following the correct technique for the level you are after, and watch the hair visually the whole time.
4. Rinse: Rinse thoroughly with water and shampoo once the desired level is reached, then finish with a toner or a mask as the service requires.

Expert Tip: Mix only what you will use right away — once the powder meets the developer the paste starts working, so a fresh bowl gives you a more even, predictable lift.

Professional use, please read: This is a professional-use cosmetic for licensed hairdressers, not a home kit. It does not work on its own and must be mixed with a hydrogen peroxide developer, which is sold separately. Always run a patch test 48 hours before the service and a strand test before each application — especially on chemically processed hair. Wear gloves, avoid inhaling the powder, keep it away from the eyes and never apply to an irritated or broken scalp.

Ingredients (Highlights)

• Hydrolyzed Collagen: A conditioning protein the brand declares in both shades, used to help hair keep a supple, elastic feel through the lightening process.
• Dust-Free Technology: A formulation feature rather than a single ingredient — the powder is granulated so it stays in the bowl instead of dispersing into the air during mixing.
• Anti-Yellow Pigment (Blue shade): The cool pigment that gives the Blue powder its shade and helps counter the look of warm undertones.
• Light Fragrance: Declared by Prohall as part of the formula, and the reason the powder smells far less sharp than most.

About Prohall Professional

Welcome to the world of Prohall Professional, a Brazilian professional hair care house built for the salon floor — smoothing systems, colour support and the lightening line this powder belongs to.

In Brazil the salon is a weekly ritual and blonde work is something close to a national specialty, which is exactly why Brazilian bleaching powders are engineered around comfort and fiber care as much as around lift. Prohall products are developed and manufactured in Brazil, where sun, humidity and back-to-back chemical services set a high bar for what a professional powder has to handle.

FAQ

What is the difference between the Blue and the White powder?

The base formula is the same — same Dust-Free technology, same Hydrolyzed Collagen, same up-to-9-levels lift. The Blue powder adds an anti-yellow pigment that helps counter the look of warm, brassy undertones as hair lifts, so it suits cool and ashy blonde briefs. The White powder is neutral, for maximum lift and the cleanest canvas before you tone.

Do I need to buy anything else to use it?

Yes. A bleaching powder does nothing on its own: it has to be mixed with a hydrogen peroxide developer, which is sold separately. Choose the developer volume that matches your technique and the level you are lifting to, and follow the mixing ratio for that service.

Is this suitable for home use?

No. It is labelled for professional use and is meant to be handled by a trained hairdresser, with gloves, in a ventilated space. Patch test 48 hours ahead and strand test before every application, particularly on hair that has already been coloured, bleached or smoothed, and discontinue use if any irritation appears.

Is the product authentic, and why is the label in Portuguese?

Every unit is genuine Prohall Professional, sourced in Brazil and shipped in its original, sealed packaging — which is why the tub is printed in Portuguese and reads 500 g / 17.6 oz. Nothing is relabelled or repackaged on the way to you.

Do you ship internationally?

Yes, MKPBR offers worldwide shipping with reliable tracking and a clear returns policy.
