Discover how PRO HAAR experts repair hair after chemical treatments. Learn the full protocol: pH, bond repair, hydration, and protection.
What does an expert do after a chemical treatment – recovery protocol explained
Every chemical treatment – from colouring to straightening or Nanoplastia – deeply changes the hair structure.
Even the most advanced formulas temporarily weaken the bonds within the hair fiber.
A true professional knows that the work doesn't stop after rinsing the product – the real recovery only begins afterward.
This is the recovery protocol that PRO HAAR experts follow for strong, shiny and long-lasting results.
1. Step 1 – Neutralization of the pH
After every chemical treatment the pH of the hair is too high (7–9).
✔ A pH that is too basic keeps the cuticle open → moisture loss, breakage, color fading.
✔ Therefore, an acidic neutralizing spray or mask (pH 3.5–4.5) is used first.
✔ This closes the scales and brings the hair back into balance.
Expert advice: Always use a pH balancer or acidic sealer after rinsing. Without it, your hair will remain fragile, no matter how well you treated it.
Step 2 – Bond Repair
Chemical processes break disulfide bridges (sulfur bridges) in the cortex.
✔ Recovery is achieved with products containing maleic acid, cysteine or amino acids .
✔ They restore the internal structure and prevent further damage.
✔ Well-known technologies: Bond Rebuilder , Plex , Reconstructing Serum .
Expert advice: Use a Bond Repair immediately after rinsing – before the mask – to fix the bonds in their new position.
Step 3 – Hydration and lipid restoration
After chemical processes, the lipid layer around the hair is depleted.
✔ Use masks with vegetable oils, ceramides, shea butter, argan oil .
✔ These restore the flexibility of the cuticle.
✔ Hydration keeps the hair supple and shiny.
Expert advice: Hydrate at least twice a week with a deep-acting mask or leave-in serum.
4. Step 4 – Heat and UV protection
After chemistry, the hair is more sensitive to external stress.
✔ Use thermal protection before every styling.
✔ Choose sprays with silicone, polymer, or protein protection.
✔ Avoid exposure to direct sunlight without a UV filter.
Expert advice: Professionals recommend avoiding heat for the first 72 hours to allow the bonds to fully stabilize.
Step 5 – Home Maintenance Routine
The recovery protocol doesn't stop in the salon – it must continue at home.
✔ Sulfate-free shampoo + mask with low pH.
✔ Leave-in serum or oil after every wash.
✔ Protein treatment once a week.
✔ Hydrating mask once a week.
✔ Use cold rinse after every wash to close the cuticle.
Expert advice: guide every client with a personalized home plan – that's the difference between temporary and lasting results.
6. Step 6 – Follow-up in the salon
✔ Check the hair condition after 4 weeks.
✔ Repeat Bond Treatment or Hair Botox as a strengthening treatment.
✔ Assess elasticity, shine and moisture balance.
Professional aftercare is the guarantee for long-term satisfaction and customer loyalty.
Conclusion: treatment only ends when recovery is complete
An expert not only treats the hair, but also guides the healing process step by step.
With knowledge of pH, bonds and lipids, every hairdresser can repair the hair from within – and that is the essence of PRO HAIR science and craftsmanship.
