Can hair smoothening be done on henna hair?

Yes, hair smoothening can be done on henna-treated hair, but it's essential to proceed with caution. Henna can alter the hair's texture and porosity, which may affect how well the smoothening treatment adheres and its overall effectiveness. It's advisable to consult a professional stylist who understands both henna and smoothening treatments to ensure the best results and minimize damage. Additionally, performing a strand test beforehand can help determine how your hair will react to the smoothening procedure.
