Stop the new product when the scalp develops persistent burning, swelling, blisters, hives, or worsening itch. Rinse it out, avoid adding other new products, and seek medical care for severe or spreading symptoms.

## Read the current label

Check ingredients, intended use, directions, and warnings on the package you have. Formulas and claims can change, so an old listing is not the source of truth.

## Keep the routine stable

Change one variable at a time. A small-area test can reduce the area exposed but cannot guarantee that a reaction will never occur.

## Safety limits

Trouble breathing, faintness, or rapid swelling of the face, lips, tongue, or throat can be an emergency. Seek urgent medical help instead of testing the product again.

## Frequently asked questions

### How often should textured hair be trimmed?

Most people do well with a light trim every three to four months, adjusted for how the ends behave. Ends that tangle, feel thin compared with the rest of the strand, or show split ends creeping upward are asking sooner. Healthy ends that seal well and hold styles can go longer between trims.

### Should I trim wet or dry hair?

Dry trimming on stretched or styled hair shows the true length and shape, which matters for curly cuts. Wet trimming is fine for even, straight styles. Either way, sharp shears made for hair are non negotiable; dull scissors crush the strand and create the splits you were trying to remove.
