Should wash day focus on the scalp or the ends?
Clean the scalp where oil and buildup collect. Let lather move through the lengths, then condition the areas that need it most.
Keep the test simple
Change one thing at a time, follow the current label, and note timing and symptoms. That makes benefit or irritation easier to identify.
When should you stop?
Stop for persistent burning, swelling, blistering, hives, or worsening symptoms. Seek urgent help for breathing trouble or severe swelling.
