As summer heats up, your scalp often pays the price. Sun exposure, sweat, and product build-up can all throw off your scalp’s natural balance, leading to itchiness, dryness, oiliness, or irritation. But there’s a quiet hero behind healthy hair: your scalp’s pH.
Let’s explore what pH means for your scalp, why it matters more in the warmer months, and how to reset your scalp’s health with a simple, natural routine.

What Is Scalp pH and Why Is It So Important?

Your scalp’s natural pH typically sits between 4.5 and 5.5, which is slightly acidic. This acidity helps maintain your acid mantle — a protective barrier that:

•  Keeps harmful bacteria and fungi at bay
•  Supports a healthy scalp microbiome
•  Regulates oil production
• Protects hair follicles
•  Prevents irritation and flaking

When your scalp is in this healthy, acidic range, your hair grows stronger, shinier, and more resilient.

What Happens When Scalp pH Is Stripped?

Unfortunately, many hair products — especially those with sulphates or alkaline pH (above 7) — can disrupt this balance. This becomes even more common in the summer, when we’re washing hair more often or exposed to sun, chlorine, and sweat.
When your scalp’s pH is too high (alkaline), it can:

• Break down the scalp barrier
• Increase itchiness, dryness, and inflammation
• Disrupt oil regulation, leading to either dryness or greasiness
• Causes flaking, breakouts, or irritation
• Weaken hair follicles, slowing growth and increasing shedding

 How to Restore a Healthy Scalp pH Naturally

Reviving your scalp’s pH is simpler than you might think, and it starts with switching to the right products and habits. Here’s how to reset your scalp health:

• Use a pH-balanced shampoo and conditioner — ideally between pH 5 and 6
• Avoid harsh detergents like sulfates and synthetic foaming agents
• Rinse hair thoroughly to avoid residue buildup
• Don’t overwash — every 2–3 days is enough for most people
• Protect your scalp from sun exposure with a hat or scarf
• Massage regularly to increase circulation and support follicle health

Why Summer Scalp Care Matters

With more time outdoors, increased sweat, and frequent washing, summer is the season when scalp imbalance is most common. That is why choosing gentle, supportive haircare is so essential.
Signs your scalp might be out of balance include:

•  Increased flaking or itching
• Feeling tight or overly oily
• Stalled hair growth
• Dull or limp hair

If you’re noticing any of these, it may be time to reset your routine.

Healthy hair starts with a healthy scalp — and a healthy scalp starts with the right pH. By avoiding harsh products and choosing natural, pH-balanced formulas enriched with scalp-supporting ingredients like Icelandic moss and marula oil, you can reset and revive your scalp this summer.
