A Brazilian Blowout hair treatment can last up to 12 weeks if it is properly maintained. The Brazilian Blowout is a cumulative treatment, and the more frequently it is done, the longer the results will last.
The manufacturer of the Brazilian Blowout recommends using its Acai After-Care Maintenance product line to ensure that the treatment will last for 10 to 12 weeks. If this product line is not used, it is suggested that the results of the Brazilian Blowout will not last as long. The Brazilian Blowout conditions and protects the hair, so as more treatments are done, the results become longer lasting.
