How should a new product be introduced?

Add one product at a time, follow the current label, and keep the rest of the routine stable.

When is medical care appropriate?

Seek care for severe, sudden, painful, spreading, or persistent skin, scalp, or hair changes.

What belongs in a simple wash-day checklist?

Check scalp comfort, cleansing, conditioning, detangling, drying method, and product buildup. Change one step at a time so results are easier to interpret.

Change one thing at a time

Keep the rest of the routine stable, follow the current label, and note timing and symptoms so benefit or irritation is easier to identify.

Stop signs

Stop for persistent burning, swelling, blistering, hives, or worsening symptoms. Seek urgent help for breathing trouble or severe swelling.
