The Line Is Not Fresh. It Is Perfume Sitting in a Waistband.

Fragranced detergent and softener leave residue that heat cooks into a rash. Fragrance-free wash, full rinse, bland cream. Softener is optional.

Key takeaways

• Fragrance-free is not the same as unscented.
• Softener and scent beads are optional films on skin.
• Quick cycles under load-shedding leave more residue.
• The dark band under elastic is often PIH on dermatitis.
