Choose from how hair behaves, not a fixed calendar. Stiffness and tangling can signal a poor fit; limp or weak-feeling hair may need a different balance.

## A careful way to test this

Keep the rest of the routine stable, follow current labels, and change one variable at a time. Stop if discomfort is persistent or severe.

## What the label can tell you

Check ingredients, directions, warnings, and intended use. Formula and claims can change, so the current package is the source of truth.

## Frequently asked questions

### How often should I use a clarifying shampoo?

Every two to four weeks for most people. Weekly suits heavy product users, dry shampoo regulars, and swimmers. Daily use is too stripping and will dry hair and fade colour.

### What is the difference between clarifying and chelating shampoo?

Clarifying removes product buildup like silicones and polymers. Chelating also removes mineral deposits from hard water and chlorine. If hair feels rough and dull in a hard water area, chelating is the more precise tool.

### Do I need to condition after clarifying?

Yes, properly. Clarifying strips the coating hair relied on for slip, so a conditioner or mask afterwards is part of the procedure, not an optional extra.

### Will clarifying fix a flaky, itchy scalp?

No. That is a scalp issue, usually needing an anti dandruff or scalp specific product. Clarifying treats buildup on the lengths. Using it for scalp conditions mostly adds dryness.
