The Best Shampoo for Oily Hair: 5 Haircare Brands That Actually Work (And What to Avoid)

Shampoo for Oily Hair

If your hair starts to feel greasy by lunchtime, you’re not alone. Oily hair is one of the most common hair concerns, especially among women who want their style to look effortlessly clean and fresh—without having to wash it every day.

The good news? With the right shampoo for oily hair, you can rebalance your scalp, add volume at the root, and stretch the time between washes. Here’s your expert-approved guide.

What causes oily hair?

Oily hair is caused by overactive sebaceous glands on your scalp. These glands produce sebum, a natural oil that protects and hydrates your scalp. However, factors like hormones, stress, diet, or overwashing can cause these glands to go into overdrive—leaving you with flat, greasy roots and dull lengths.

What to look for in a shampoo for oily hair

When shopping for a shampoo for oily hair, you need a formula that gently removes excess oil without stripping your scalp (which can trigger more oil production).

Key ingredients to look for:

• Salicylic acid – gently exfoliates the scalp and helps unclog oily hair follicles
• Clay (like kaolin or bentonite) – absorbs excess sebum
• Charcoal – detoxifies and deep cleans
• Tea tree oil – has antibacterial and soothing properties
• Witch hazel – a natural astringent that helps tighten pores and regulate oil

Avoid: heavy silicones, creamy moisturising shampoos, or anything labeled “hydrating” or “nourishing” unless it’s targeted for oily scalps.

How often should you wash oily hair?

You might think you need to wash every day, but that can actually make things worse.

• Start with every other day and use a clarifying or oil-controlling shampoo
• Use dry shampoo on non-wash days to absorb oil and maintain volume
• Once a week, use a scalp exfoliating shampoo or treatment

Expert tip: “When washing your hair shampoo your scalp twice and only condition the ends. It sounds simple but so many women forget this basic routine.”

Why does my hair get greasy so fast?

Hormones, over-washing, and using the wrong products (like heavy conditioners at the root) can all cause increased oil production.

Should I use conditioner if I have oily hair?

Yes—but only on the mid-lengths and ends. Avoid applying it near the roots.

Is dry shampoo bad for oily hair?

Not at all! Just make sure to wash it out thoroughly. Dry shampoo is your best friend between wash days, but overuse can clog follicles.

Can diet affect oily hair?

Yes. High-glycaemic foods, dairy, and stress can all increase sebum production. A nutrient-dense diet supports healthy scalp balance.

Will washing my hair less stop the oil?

Eventually—yes. It’s called “training” your scalp. Give it time, use the right shampoo, and gradually extend time between washes.

The Secret to Clean, Fresh Hair Every Day

The best shampoo for oily hair isn’t about stripping your scalp—it’s about rebalancing it. Choose formulas with clarifying yet gentle ingredients, avoid product build-up, and pay attention to how your scalp reacts to your routine. Oily hair doesn’t have to be your default. With the right care, your blow-dry can last longer—and your hair will finally feel as clean as it looks.
