Ultimate Treatment has been designed to be long-lasting (up to 4 months).
On hair that has had previous chemical services, the results are more dramatic and last longer. With hair types that are natural with no chemical service history, the results are better and last longer after subsequent treatments. The earliest Ultimate Treatment can be re-applied is 30 days.
Once hair has been transformed with Ultimate Treatment it needs to be maintained with KeraStraight Moisture Enhance or Volume Enhance Shampoo and Conditioner to maximise the benefits and longevity of the treatment.
