At room temperature, out of direct sunlight. Once opened, use within 12 months for best results.
First improvements are typically visible from 10 days. For significant results, we recommend using Calmbay consistently for at least 30 days. Many people see continued improvement up to 60 days, so for the best outcome, give it the full course.
We recommend it. Dandruff is linked to scalp microbiome balance and balance needs maintenance. You can reduce the treatment frequency to once a day or a few times per week, and use the Calmbay shampoo at least once a week alongside your regular routine. This keeps the scalp in balance and helps prevent flare-ups. One bottle is sufficient for 2 applications per day for 60 days.
Yes. Calmbay is designed to fit into your current routine, not replace it.
If you're under treatment from a dermatologist or trichologist, we suggest checking with them before combining Calmbay with prescribed products.
