Why Your Scalp Gets So Oily & How to Help | As Seen in HuffPost
An oily scalp can feel frustrating, especially when your hair looks greasy just hours after washing. Dr. Mona Foad, featured in HuffPost, explains what actually drives excess oil production on the scalp, which ingredients and products help rebalance it, and the simple habit changes that can make a real difference. Whether you’re dealing with genetics, hormones, or the wrong hair care routine, here’s what to do about it.

Are there certain factors that cause an excessively oily scalp or make someone more prone to oily hair?
The scalp naturally produces oil, known as sebum. This oil is essential for maintaining healthy, hydrated hair and protecting the skin’s barrier. A balanced amount keeps the scalp comfortable and adds shine and flexibility to the hair.
However, when oil production becomes excessive, it can cause problems. Greasy, flat hair shortly after washing is a common sign. Some people also experience scalp irritation or breakouts around the hairline.
Genetics plays a major role. Some people naturally have more active oil glands. Hormonal fluctuations during puberty, pregnancy, or periods of stress can further increase oil output. Conditions like dandruff, eczema, or psoriasis may also contribute. Overwashing or using harsh hair products can strip the scalp, causing it to produce even more oil to compensate.
What are some products you recommend for an oily scalp?
An oily scalp that feels greasy even after washing can benefit from rebalancing products. The key is finding something that controls oil without over-drying the skin.
Look for shampoos that contain salicylic acid, zinc pyrithione, selenium sulfide, or ketoconazole. These ingredients help exfoliate the scalp, reduce buildup, and calm inflammation linked to excess sebum.
The Neutrogena Healthy Scalp Clarify & Shine Shampoo is a great option. It uses gentle exfoliants to lift away residue and balance oil while keeping hair lightweight and shiny. The Living Proof Clarifying Detox Shampoo is another excellent choice. It removes excess oil and product buildup without stripping the scalp’s natural moisture barrier.
In between washes, reach for a dry shampoo with rice starch or kaolin clay. These ingredients absorb surface oil and keep hair feeling fresh. The goal isn’t to eliminate all oil — it’s to maintain a clean, balanced scalp that supports healthy hair.
For those with seborrheic dermatitis or psoriasis, a tar shampoo like TGel or a prescription ketoconazole shampoo may be worth considering.
Are there other things someone can be doing to prevent an overly oily scalp?
Yes. Simple adjustments to your hair care habits can make a big difference.
Start with washing frequency. Some people do well shampooing daily with a gentle, pH-balanced cleanser. Others may need to wash less often to avoid overstimulating oil production. It varies from person to person.
When you do wash, focus on the scalp rather than the length of the hair. Use your fingertips — not your nails — to avoid irritation. Apply conditioner only to the mid-lengths and ends. Putting it near the scalp can weigh hair down and make it look greasier.
Product choice matters too. Look for lightweight, silicone-free formulas designed for oily scalps. Ingredients like salicylic acid, tea tree oil, and green tea extract help balance oil and calm inflammation.
Heat styling can contribute to oil buildup over time. Air-drying when possible is a good habit. Keeping brushes and styling tools clean also helps maintain a fresher, healthier scalp.
