At the start of your routine, when ends are very dry, fragile, and hair tangles easily, use the treatments every day or every other day for 1 month, depending on your hair's needs.
Once your hair has regained more suppleness and the ends are better protected, gradually space out the treatments to every 3 to 4 days to maintain the results.
Intensive phase: every day to every other day for 1 month.
Maintenance phase: every 3 to 4 days.
