Master Mechas + OX 05 · Kit · 500 g + 900 ml
What this presentation contains
One Master Mechas bleaching powder, 500 g, and one OX 05 developer, 900 ml. No toner, CCRP or post-lightening mask is included in this set.
01 / Understand the product
What it does
The role of the powder, the developer and the selected presentation.
This kit groups two different components: the powder and the named developer. It is useful for identifying what is supplied together, but the packaging does not choose the service or replace either label. To replenish just one component, open its individual page instead of assuming another complete kit is needed.
When to use
Choose the set only after the professional has established that its exact developer is appropriate for the service. The 500 g and 900 ml quantities are package contents, not a recommendation to mix both full containers. Subsequent toning and care depend on the result and the separate products' instructions.
Specific indication not confirmed in the consolidated guide. Use only when the exact base-product protocol identifies OX 05.
Understand before choosing
Open the topic that answers your question. The essential purpose stays visible above.
What is combined in this kit?
The powder and the named developer are supplied together. They keep their own identities and labels. The set is not a premixed product and does not contain a third treatment step.
Two package sizes are not a formula
The amounts printed on the containers describe what you buy. They do not set the quantity to prepare for one service. The current mixing ratio and professional assessment govern preparation; do not empty both containers together by default.
Why the OX number matters when choosing the set
The kits can look similar while containing a different developer strength. Identify the OX number explicitly before purchase and match it to the already established professional protocol. The set does not select the appropriate strength for you.
What comes after the lightening service?
Toning and post-lightening care are separate stages to evaluate after the service. A toner, Master Love or CCRP is not automatically supplied or required by the purchase of this powder-and-developer set.
Understand the OX strengths
Reference information from the brand's consolidated guide. It explains the range; it does not select a developer for your hair or service.

Developer identified in this presentation
About this developer - OX 103%
Hydrogen peroxide
The brand's guide associates OX 10 with gentle toning and colour adjustments, only in compatible systems that specify this strength.
About this developer - OX 206%
Hydrogen peroxide
The brand's guide associates OX 20 with light lightening and permanent colour. This does not establish a fixed number of levels.
About this developer - OX 309%
Hydrogen peroxide
The brand's guide describes medium lightening and coverage on resistant hair. The word resistant does not replace assessment or establish a universal hair category.
About this developer - OX 4012%
Hydrogen peroxide
The brand's guide describes more intensive lightening. A higher strength is not automatically a better or suitable choice for a particular head of hair.
About this developer
The service, compatible base product, chemical history and required tests govern selection. Do not mix strengths or substitute one for another from this comparison.
02 / Master Mechas
Use guidance
A service that specifically calls for OX 05
Professional use. Follow the current labels and required tests. Do not use on an irritated or injured scalp or on eyelashes and eyebrows. Wear suitable gloves and avoid contact with eyes.
What the professional needs to establish
This is a preparation guide, not a complete mixing or processing recipe. The selected products' current labels determine the ratio, application conditions and processing limits.
Mixing ratio: follow the current lot
The technical sources retain differing powder-to-developer ratios. This page does not turn them into freely interchangeable options. Confirm the current lot's instructions before preparing the mixture.
OX 05: confirm the exact instructions
The consolidated source does not confirm a specific indication or peroxide percentage for OX 05. Its presence in a kit does not resolve that missing technical information.
Hair and objective
Identify the starting colour, target service, chemical history and present condition. Complete the sensitivity and strand checks required by the product instructions.
Products and preparation
Check the exact powder and developer, their labels and the specified ratio. Use suitable gloves and a non-metallic mixing container.
Monitoring and finishing
Plan monitoring, stopping criteria, rinsing and subsequent care from the service instructions. Do not extend processing merely because the desired colour has not been reached.
About the technical information
Identity and pack contents were checked against the European catalogue. Roles, warnings and the OX comparison follow the consolidated technical dossier, pages 47–52 and 79. Current lot labels take precedence. This page does not claim that the full protocol has been reconciled.
Pack size is not the application amount or the number of services. The current base-product instructions determine the mixture and processing conditions; no universal dose or repeat interval is supplied here.
03 / Powder, developer and kit
Different roles. A clearly identified set.
The powder and the specified developer are components of the lightening preparation. A kit contains them; it is not a third application.

Your questions, answered
Open a question for guidance specific to this product.
Is this the individual product or the kit?
One Master Mechas bleaching powder, 500 g, and one OX 05 developer, 900 ml. No toner, CCRP or post-lightening mask is included in this set.
Should I mix all 500 g with all 900 ml?
No. Those are the sizes supplied, not one-service mixing instructions. The professional measures the amount and ratio required by the current product labels.
Does this set contain post-lightening treatment?
This exact set contains powder and the identified OX only. Toner, masks and CCRP are not included and are not automatically prescribed by the purchase.
Can I replenish just the powder or the developer?
Yes, the individual component pages below identify each separately. Confirm the same product and presentation; a different OX strength is not an automatic substitute.
Is this for home use?
This lightening/developer range is for professional use. It is not a Home Care cleansing or conditioning routine.
Can the page choose an OX strength for me?
No. The professional must consider the compatible base product, technique, starting colour, chemical history and required tests. The comparison explains the range without prescribing a strength.
What mixing ratio and processing time should I use?
Follow the current labels and service protocol. The powder sources retain a ratio discrepancy and no universal time is established here. Neither a pack-size calculation nor a desired number of levels resolves those points.
Can I combine different developer strengths?
The consolidated guidance does not authorise mixing OX strengths or substituting one for another without a specific protocol. A comparison between products is not a mixing formula.
What should be checked before application?
Check the product identities, current labels, chemical history and required sensitivity/strand tests. Use suitable gloves and a non-metallic container. Do not apply to an irritated or injured scalp, eyelashes or eyebrows; avoid eyes.
