What do I have to consider when changing chemically coloured hair?Updated 24 days ago
To ensure that chemically pre-treated hair, i.e., bleached, chemically colored, or permed, achieves the desired shade, pre-treatment with Senna/Cassia is recommended.
If you want to change from chemically lightened hair to a significantly darker shade, pre-pigmentation with our ColorPrep may be advisable.
Regardless of whether the hair has been chemically treated or not, we highly recommend using DeepCleanse Shampoo before every coloring session.
Please also note that on chemically darkened hair, only the roots may need to be recolored if the lengths are still sufficiently dark. If you are unsure whether a complete color change or just a root touch-up is more suitable for you, please feel free to contact us at [email protected].
