Could I have this treatment done at home? Or is it necessary to have it done in a hairdresser?

Hello Alejandra, thank you for your inquiry. The Olaplex treatment nº1 and nº2, that is, the first two steps, are for professional use since they must be applied in the coloring / aggression process as indicated by the brand. So to achieve good results, it should not be used at home, only by a professional. All the best.
