If you have rough or porous hair, you must have the impression that even if you do hydration, nutrition or even reconstruction, your hair is still the same, right? It gives the impression that the treatment comes out in the water, and it looks like you haven't even used anything!
This has an explanation, besides regular treatments to replace proteins, nutrients and water lost from the strands, hair pH is also important! If hair is left with an alkaline pH (unregulated) its cuticles remain open, causing roughness and porosity and making the hair shaft unable to hold any treatment.
ACIDGOLD will be responsible for closing the hair cuticles, so that the hair becomes healthier, shinier and, above all, strong and protected.
