How to Choose the Right pH-Balanced Shampoo for Your Scalp Type

If you’ve ever wondered why your shampoo leaves your scalp itchy, oily, or just “off,” the answer might come down to pH balance. At Runway Blowout Lounge, we talk about this a lot with our clients. The right shampoo can make or break your hair health. Let me, Stephanie, walk you through how to match your scalp type with the right pH-balanced formula.

Why pH Balance Matters

Your scalp naturally sits around a pH of 4.5–5.5, which is slightly acidic. That acidity keeps bacteria under control, keeps the cuticle closed, and protects your scalp’s natural oils. Shampoos that are too alkaline can leave your scalp dry and irritated. Too acidic, and your hair might feel heavy or coated. The sweet spot? A shampoo that respects your scalp’s natural pH range.

Scalp Type #1: Oily Scalp

If your scalp feels greasy by the end of the day, you’ll want a shampoo that’s pH-balanced but leans slightly lower (around 4.5). This helps keep oil production in check without stripping your scalp bare. I usually recommend lightweight, clarifying options from our shampoo collection. Look for labels that say “balancing” or “oil control.”

Scalp Type #2: Dry or Flaky Scalp

Dryness is often a sign your shampoo is too alkaline. A formula closer to 5.5 will be gentler, locking in moisture and calming irritation. Maria on our team loves pairing clients with hydrating shampoos that still sit in the safe pH range. Adding a scalp treatment once a week can also make a big difference for flakiness.

Scalp Type #3: Sensitive Scalp

If your scalp gets red, itchy, or stings easily, stick with shampoos specifically marked as pH-balanced for sensitive skin. These usually hover right around 5.0. Avoid heavy fragrances or sulfates, since they can trigger more irritation. A gentle cleanse plus lightweight conditioner is usually all you need to feel comfortable again.

Scalp Type #4: Normal / Balanced Scalp

If you’re lucky enough to have a scalp that isn’t too oily or dry, don’t overcomplicate things. A well-formulated pH-balanced shampoo between 4.5–5.5 will keep you in that healthy range. For many of our Ramsey clients, we suggest alternating between a gentle daily shampoo and a treatment shampoo once or twice a week to keep things balanced.

Quick Stylist Tips

• Always rinse thoroughly—residue throws off balance as much as a wrong formula.
• Don’t wash too often. Even the right shampoo can backfire if you overuse it.
• Pair your shampoo with a conditioner in the same line for best results.

How to Know If You Picked the Wrong One

If your scalp suddenly feels itchy, overly oily, or your hair looks dull, your shampoo might not match your scalp type. Switching to a proper pH-balanced formula usually clears things up within two to three washes. If not, it’s time to check in with a stylist—we can spot issues fast and recommend the right fix.
