Hair, Explained isn’t a fixed-length program — it’s an ongoing routine that adapts as your hair changes.
What to expect over time:
First 4–6 weeks: changes in texture, manageability, and shine usually become noticeable.
8–12 weeks: deeper improvements in damage and porosity start to show.
3+ months: enough progress photos to compare side-by-side and refine the routine.
There’s no graduation date — your routine evolves with your hair, the seasons, and any treatments you do. Plan to stick with it long enough to see the changes, and refresh your analysis every 4–8 weeks so the recommendations stay in step with what your hair actually needs.
