If your routine used to work and now doesn't — or has never quite worked — there's almost certainly a real reason. Here are the seven most common ones, with quick diagnostics for each.

The number-one cause of "my hair just won't behave." Hair needs both — and tipping too far either way creates real problems.

Diagnostic: The wet-strand stretch test. Snaps immediately = too much protein. Stretches forever and doesn't bounce back = too much moisture. Full guide here.

Silicones, butters, oils, hard-water minerals, and styling polymers accumulate over weeks. Hair stops absorbing moisture, looks dull, feels weighed down, and "won't take" products it used to like.

Diagnostic: Hair feels coated even after washing. Water beads up more than usual. Roots oil up faster than they used to. Fix: a clarifying shampoo or chelating treatment.

If your products are formulated for the wrong porosity, they'll either build up (heavy products on low-porosity hair) or fail to seal moisture (lightweight products on high-porosity hair).

Diagnostic: Run the spray test. Then check your products against your actual porosity.

Same routine, different humidity. Glycerin that helped in summer can pull moisture out of your hair in winter. Heavy creams that worked in cold weather feel suffocating in summer.

Diagnostic: Did it work last season? Did the weather change recently? Fix: rotate seasonal products or ask Rituala for a seasonal adjustment.

Brands change formulas without telling anyone. A product that worked for years can suddenly stop working because the ingredients silently shifted.

Diagnostic: Pull up the current ingredient list and compare to an old bottle if you have one. Fix: if reformulated, ask Rituala for an alternate.

Heat tools, colour, sun, chlorine — damage compounds. Routines built for healthy hair stop fitting once damage tips over a threshold.

Diagnostic: More breakage at ends? More frizz than before? Curls less defined? Fix: retake the quiz with current condition flagged honestly.

Pregnancy, postpartum, perimenopause, thyroid issues, new medications, rapid weight loss, or sustained stress all change hair behaviour — sometimes dramatically.

Diagnostic: Has anything in your body changed? Fix: retake the quiz, mention what's changed, and consider seeing a dermatologist if shedding is significant.

Don't change five things at once. Pick the most likely culprit, address it for 2–4 weeks, and see what shifts. Hair takes time to respond.
