The Prime Pro Extreme Bio Tanix Repair Mask — 1kg is a professional-grade tannin mask built around the brand’s proprietary Force-Plastia technology. Used as a standalone in-salon ritual after the Bio Tanix Purifying Shampoo Step 1, it works as a 30-minute deep-conditioning mask or, with an optional flat-iron sealing step at 200°C (180°C on blondes), unlocks the full Bio Tanix smoothing effect — formaldehyde-free, smokeless, salon-grade.

What it is

The Bio Tanix Repair Mask is Prime Pro Extreme’s 1kg salon mask, formulated to fill the hair fibre with low-molecular-weight protein, replenish lipids, and seal the cuticle in one application. Two protocols sit inside the same jar: as a conditioning mask you rinse and blow-dry for shine and softness; as a botanical smoothing ritual you flat-iron in thin sections to lock in volume reduction and frizz control. The professional format yields multiple salon applications and pairs with the Bio Tanix Purifying Shampoo Step 1 for prep, plus the Bio Tanix Home Care Kit for at-home maintenance.

Key ingredients

• Tannic Acid (Acacia Negra / Black Wattle Tree): the Force-Plastia smoothing active — acts on disulphide bonds via pH-activated hydrogen release
• Milk Protein: low-molecular-weight protein for mass replacement and fibre strengthening
• Pearl Powder: mineral and amino acid complex for nutrition and conditioning
• Royal Oils blend (Argan, Olive, Grape Seed, Shea Butter): lipid-replenishing matrix that seals the cuticle and adds shine
• Cetrimonium Chloride + Cetearyl Alcohol: cationic conditioning system for slip and detangling

What you can expect

With proper application and professional aftercare, the Bio Tanix Repair Mask delivers visible softness, satin touch, and intense shine from the first session. With the full flat-iron sealing step, you can expect targeted volume reduction, smoother strands, and frizz control that lasts up to 6 months with proper application and professional aftercare. Blonde and bleached hair is preserved without yellowing thanks to the lower 180°C ironing rule. The fibre feels denser as protein and the Royal Oils matrix fill micro-gaps. No colour fading, no smoke, no formaldehyde fumes.

Who it is for

• Stylists and salon clients seeking a formaldehyde-free smoothing alternative
• Frizzy, voluminous, or thick hair needing controlled volume reduction
• Coloured, bleached, or highlighted hair — the formula does not fade pigment
• Curly and Afro-textured hair that benefits from longer processing times
• Hair stressed by heat tools or chemistry needing lipid and protein replenishment

Who it is not for

• Known allergies to listed fragrance allergens: Benzyl Benzoate, Benzyl Salicylate, Coumarin, Hexyl Cinnamal, Linalool, or Limonene
• Milk-protein, argan, or olive allergies — all three are present in the formula
• Sensitivity to BHT or Phenoxyethanol preservatives
• Pregnant or breastfeeding without a medical green-light (the brand claims Bio Tanix is safe; we still recommend consulting a professional)
• Anyone under 14
• Shoppers seeking certified vegan or organic-certified formulations

Professional recommendation

• Always perform a strand test and patch test at least 48 hours before full application
• Pre-cleanse with the Bio Tanix Purifying Shampoo Step 1 to lift residue and build-up
• Towel-dry to 50% damp and divide hair into four equal sections
• Apply with a fine-tooth comb for even distribution, layer by layer
• Extend processing time for thick or curly hair beyond the 30-minute baseline
• Use a salon-grade titanium iron like the Nano Titanium Pro 1.75 for even heat
• Maintain results with the Bio Tanix Home Care Kit between salon visits

How to use

A. Standard Manufacturer Method (from the label)

1. Shampoo with the Bio Tanix Purifying Shampoo Step 1; rinse thoroughly
2. Towel-dry 50% of the hair and divide into four equal sections
3. Apply the Repair Mask layer by layer with a fine-tooth comb
4. Leave on for 30 minutes (longer for thicker curl structure)
5. Rinse with water until clear, then blow-dry to activate shine
6. Optional smoothing: flat-iron in thin sections, 5–10 passes at 200°C (180°C on blondes), more at the root
7. Finish and style as desired

B. Expert Salon Method (with hair-type tuning)

1. Pre-cleanse with Step 1 using palm pressure only (preserve the scalp); rinse fully
2. Towel-dry to 50% and section into 4 equal parts
3. Apply with comb, 0.5cm from the scalp, in thin layers
4. Process by hair type: fine 30 min / 180°C max; normal 30–35 min / up to 200°C; thick 35–45 min / up to 230°C; blonde 30 min / 180°C max
5. Rinse without shampoo until water runs clear
6. Blow-dry with a round brush until smooth
7. Flat-iron in thin sections, 5–10 passes, more at the root and less at the ends
8. Finish with Magic Help Leave-in Spray for thermal protection

Compatibility

The Bio Tanix Repair Mask is compatible with coloured, bleached, highlighted, keratin-treated, and chemically straightened hair, with a mandatory strand test on heavily processed sections. It pairs naturally with the Bio Tanix Extreme professional system — the Purifying Shampoo Step 1 is the dedicated pre-cleansing prep, and the Bio Tanix Home Care Kit extends salon results between sessions. As an alternative full-system route, Prime Pro Extreme also offers the Thermal Complex Keratin line for hair primarily stressed by chemical processes. The two systems are alternatives, not combined within the same session.

In short

• Force-Plastia tannin technology — formaldehyde-free smoothing active from Acacia Negra
• Hybrid protocol — conditioning mask without flat-iron, or sealed smoothing with flat-iron at 200°C
• Salon-grade 1kg jar — multiple applications; pair with the Bio Tanix Purifying Shampoo Step 1 and the Bio Tanix Home Care Kit 1100ml for the full routine
