Unbroken Blonde 1L - Cadiveu Blonde Reconstructor is the in-bleach damage protector of the Blonde Reconstructor salon system, a conditioning shield you mix into the lightener itself at 6 g per 20 g of bleaching powder. Built on 15 amino acids and UV filters, it works during the bleaching process to guard the fibre against breakage while you lighten, so the hair that comes off the foils is stronger and readier for reconstruction. It is a professional bleach-service additive, not a leave-on treatment or a smoothing product.

Why Unbroken Blonde

Bleaching is where blonde hair takes the most damage: the process swells and weakens the fibre, and it is where breakage starts. Unbroken Blonde puts the protection inside the bleach itself. Mixed at 6 g per 20 g of bleaching powder, its 15 amino acids reinforce the fibre with an anti-breakage action while UV filters and shea lipids shield and condition it through the lift. Because it works during the service rather than after it, the hair that comes off the lightener is in better condition and readier for the reconstruction steps that follow.

Key Ingredients

The protection comes from a 15 amino acid complex (keratin amino acids plus arginine, aspartic acid, glycine, alanine, serine, valine, isoleucine, proline, threonine, histidine and phenylalanine) that reinforces the fibre against breakage, backed by UV filters (ethylhexyl methoxycinnamate and ethylhexyl triazone), panthenol and shea (butyrospermum) lipids for condition. Because it contains keratin amino acids, Unbroken Blonde is not vegan.

What to Expect

Used in every bleach mix, Unbroken Blonde changes what comes off the lightener: the fibre is better protected through the lift, so the hair is stronger, less prone to breakage and in better condition to take the reconstruction that follows. It is a service additive rather than a finished result on its own: it sets up the Clarifying Shampoo, Fiber Filler and pH-Balancing steps, and the aftercare, to work on healthier hair.

Who It Is For

• Colorists and salons doing bleach, highlight and lightening services
• Blonde work on fragile, previously-processed or high-lift hair that needs breakage protection
• Any lightening service that wants to protect the fibre during the process, not only after

Who It Is Not For

• Home users: this is a professional bleach-service additive mixed into the lightener, not a retail product
• Anyone wanting a vegan formula, which this is not, as it contains keratin amino acids
• A colorist who saves the amino acids for after the lift instead of the mix

Professional tip: weigh it rather than eyeball it, at 6 g of Unbroken Blonde to every 20 g of bleaching powder, so the protection stays consistent batch to batch. Mix it into the powder-and-oxidant cream until fully homogeneous before you start, and follow through with the Fiber Filler Mask and the rest of the reconstruction once you rinse the lightener.

How to Use

Unbroken Blonde works inside the bleach itself, then hands the reconstruction over to the rest of the Blonde Reconstructor system. Run the full flow:

1. Mix the bleach: combine Cadiveu Professional Bleaching Powder and Oxidant as usual, add 6 g of Unbroken Blonde per 20 g of bleaching powder and mix to a homogeneous cream, then start the bleaching process.
2. Lighten as usual with the protected mix, then rinse out.
3. Step 1, Clarifying Shampoo: apply to damp hair, work into a lather, leave on for 5 minutes and rinse thoroughly (repeat if needed) to clear residue and heavy metals.
4. Step 2, Fiber Filler Mask: on clean, towel-dried hair, work in sections from the nape hairline, comb through for even distribution, then leave on for 5 minutes and do not rinse.
5. Step 3, pH-Balancing Mask: layer it straight over the un-rinsed Step 2, section and comb through, leave on for 10 minutes, then rinse clean.
6. Finish, the Blonde Lock leave-in: distribute a small amount evenly through wet or dry hair and do not rinse.

Use gentle heat over the mask steps to optimize the result.

After the service, send the client home with the Blonde Reconstructor home care (Blonde Keeper Shampoo and Acidic Mask) to hold the result between visits.

Where It Fits in the Blonde Reconstructor System

Unbroken Blonde is the bleach-service step of the salon system: it goes into the lightener, then the reconstruction follows on the rinsed hair with the Clarifying Shampoo (Step 1), the Fiber Filler Mask (Step 2) and the pH-Balancing Mask (Step 3). The four sit in the Blonde Reconstructor salon range, and clients keep the result up with the Blonde Reconstructor home care.
