In short: L'Oréal Blond Studio is L'Oréal Professionnel's salon lightening range. At Hairco & Beauty it covers lightening powders, a paste and clay for every technique — from foils to freehand and balayage — plus the oil developers to mix them with. This guide explains what each does and how to choose between them.
Written for salon professionals. Always follow the manufacturer's instructions on pack, complete a strand test, and carry out the recommended skin/allergy alert test before any lightening service.
What is L'Oreal Blond Studio?
Blond Studio is L'Oreal Professionnel's professional lightening line — a full toolkit of powders, a paste and a balm designed for different lightening techniques, several with built-in bond protection. Because there's a dedicated product for foils, freehand and balayage, you can match the lightener to the service rather than forcing one product to do everything.
The lightening powders and pastes
- Blond Studio 9 Bonder Inside Lightening Powder — lifts up to 9 levels with bond protection built in, for strong lift with added fibre care.
- Blond Studio 9 Levels Lightening Powder — a high-performance powder lifting up to 9 levels.
- Blond Studio Multi-Techniques Blue Powder Bleach — a versatile, blue-toned powder for a range of techniques, with anti-brassiness from the blue base.
- Blond Studio Platinium plus Paste — a strong lightening paste for maximum lift, ideal for foil and wrapped techniques.
- Blond Studio Clay Freehand Powder — a clay-based powder that stays put and resists swelling and drying out, made for freehand and balayage.
- Blond Studio BI Purple Balm Lightener — a purple-toned balm lightener for freehand work, helping control warmth as you lift.
The oil developers
Blond Studio powders are mixed with the Blond Studio developers — the 20 Vol (6%) and 30 Vol (9%) Oil Developers, plus the Nutri-Developer for a more conditioning mix. Mixing ratios vary by product and technique (commonly around 1:1.5 to 1:2), so always follow the ratio on the pack.
How to choose
- Foils and wrapped techniques: Platinium plus Paste or the 9-level powders for maximum, controlled lift.
- Freehand and balayage: Clay Freehand Powder or the BI Purple Balm, which stay where you place them.
- Maximum fibre care: 9 Bonder Inside for built-in bond protection on stronger lifts.
- Cooler results: the Multi-Techniques Blue Powder and Purple Balm help counter warmth as you lighten.
How to stock Blond Studio
- Stock a foil/wrap powder and a freehand product so you're covered for every lightening service.
- Keep both 20 and 30 Vol developers on hand for different lift levels.
- Lead with a bond-protected option (9 Bonder Inside) for clients having stronger lifts.
Frequently asked questions
How many levels does Blond Studio lift?
It depends on the product — the 9 Bonder Inside and 9 Levels powders lift up to 9 levels, while the clay and balm options are designed for controlled freehand lift. Always follow the on-pack guidance and strand test first.
Does Blond Studio have bond protection?
Yes — the 9 Bonder Inside Lightening Powder has bonding technology built in, so you don't need a separate additive for that product.
Which Blond Studio is best for balayage?
The Clay Freehand Powder is made for freehand and balayage — it stays put and resists swelling and drying out. The BI Purple Balm is another freehand-friendly option.
What developer do I mix with Blond Studio?
Use the Blond Studio Oil Developers (20 or 30 Vol) or the Nutri-Developer, following the mixing ratio on the pack.
