01 / THE DETAILS
The familiar signs overlap
Hair that feels brittle can have weathered cuticles, repeated heat exposure, chemical changes or heavy product residue. Hair that feels soft but snaps may still be severely processed. One touch test rarely tells us which ingredient category will help.
Water affects hair flexibility and dimensions, while proteins, polymers and conditioning ingredients interact with fibres in different ways. Labels alone are not enough to predict results.
02 / THE DETAILS
Conditioning and strength are different outcomes
A product can improve slip and reduce friction, making hair easier to detangle, without restoring lost keratin structure. Another can temporarily alter stiffness or feel. The effect depends on formula, concentration, application and the condition of the fibre.
More is not always better. Layering heavy treatments can also change how hair feels and styles.
03 / THE DETAILS
Build a manageable routine
Identify the main complaint: frizz, snapping, dullness, dryness or reduced curl definition. Then look at the relevant causes, including bleaching, heat and washing habits.
Good professional advice is specific enough that you can tell whether the routine actually helped.
