Struggling with greasy roots or oily build-up? You’re not alone. Oily hair is a common issue that can make your hair feel heavy, look flat, and require more frequent washing. At Welzo, we offer a carefully curated selection of shampoos for greasy and oily hair, designed to remove excess sebum, deeply cleanse the scalp, and extend the time between washes — all without stripping your hair of essential moisture.

Whether your scalp is naturally oil-prone, affected by product build-up, or reacting to hormonal changes, our shampoos help restore balance and leave your hair feeling fresher for longer.

What Causes Oily Hair?

Greasy hair is typically caused by overactive sebaceous glands, which produce too much natural oil (sebum). This may be genetic, hormonal, or triggered by environmental factors like heat, humidity, or using overly harsh shampoos. When your scalp becomes too dry, it may actually produce more oil to compensate — leading to a frustrating cycle.

That’s why it’s important to use a shampoo specifically formulated for oily hair — not just any cleanser. Our collection includes sulphate-free, pH-balanced, and clarifying formulas that target grease without irritating the scalp.

Best Ingredients for Oily Hair Shampoo

The shampoos in this range feature powerful but gentle ingredients known to combat oil and refresh the scalp:

• Salicylic acid – Gently exfoliates the scalp and removes excess oil

• Charcoal & clay – Absorb sebum and detoxify the scalp

• Tea tree oil – Offers natural antimicrobial benefits and balances oil production

• Menthol & peppermint – Deliver a cooling, refreshing cleanse

• Zinc PCA – Helps regulate sebum without over-drying

You’ll find these ingredients across products from trusted brands like Neutrogena, Head & Shoulders, and Plantur — all specially formulated to tackle oil-prone scalps.

Complete Your Routine

Pair your shampoo with lightweight hair conditioners that won’t weigh your hair down, and avoid heavy oils or styling creams that can worsen oil build-up. If you style your hair often, use light hair styling products that are easy to wash out and won’t clog your scalp.

For a deeper reset once or twice a week, add a clarifying shampoo to your routine. And if oiliness is linked to hormonal or scalp imbalances, explore our expert-led advice in the Hair Loss Treatment hub, or browse all Hair Care solutions to build a complete plan.
