Deep conditioning treatments leave hair looking smooth and shiny, add moisture to your hair, and protect your hair from damage. Deep conditioning treatments can be part of a regular hair healthy regimen. Deep conditioners strengthen, detangle and help prevent split ends. Since deep conditioning treatments replenish moisture in the hair, if done regularly, they can prevent hair from becoming damaged when heat is applied during styling.
I recommend Deep Conditioning every week (if your schedule allows). But if not then every other week for sure!
