💡 Pro Tip: If you’re between washes, rinse with water only—it removes sweat and dust without stripping oils.

❌ Debunked: “Washing Makes Hair Oilier” — Myth or Truth?

Mostly a myth—but with nuance.

Your scalp produces oil (sebum) based on genetics and hormones, not how often you wash.

However, harsh shampoos or overwashing can temporarily trigger rebound oiliness as your scalp tries to compensate for dryness.

✅ Solution: Use a gentle, sulfate-free shampoo and avoid scrubbing aggressively.
