What causes greasy hair?

Greasy hair is often caused by overactive sebaceous glands in the scalp - these are responsible for producing sebum, a natural oil to keep hair healthy and moisturised. Due to different factors, these glands can sometimes produce too much oil, causing your hair to become greasy. This can include hormonal changes, genetics, humidity, diet and stress, according to WebMD.

How to prevent greasy hair

The good news is - there are several different actionable ways in which to prevent this greasy hair dilemma. Here are some top recommendations to keep your hair looking fresh, clean, and grease-free:

• Use a shampoo specially formulated for greasy hair: these will target heads prone to greasy hair and will help remove any buildup of excess oil.
• Ensure you rinse hair thoroughly when washing: this will remove any excess product which could lead to an oily build-up on the scalp.
• Avoid using hot water when washing your hair: this can stimulate oil production - instead, try lukewarm water.
• Be gentle when shampooing: our hair expert David Felstead expresses the importance of being gentle with oily scalps, ‘to not over stimulate the sebaceous glands that cause it.’
• Avoid over-washing your hair: it can strip your hair of natural oils and result in increased oil production.
• Avoid hair products that contain heavy oils: they will make your hair look greasier and feel heavier.
• Use a dry shampoo between washes: this works to absorb excess oil, keeping hair fresher for longer.
• Look at your diet: certain foods can affect the condition of your hair, in particular those high in saturated fats and refined carbohydrates.
• Manage your stress: decreasing stress levels will help prevent the overproduction of oil in the scalp.

How to choose the right shampoo for greasy hair: ingredients to look for and avoid

When choosing a shampoo to help combat greasy hair, it’s important to look at the ingredients and pick ones specifically formulated for greasy, oily hair types. Our expert Luke Benson recommends that you ‘look for products that scientifically support the scalp to help reduce the amount of sebum produced to really help the problem.’

Here are some key ingredients to look out for:

• Salicylic acid: This has exfoliating properties, unclogging hair follicles and helping to reduce the build-up of oil on the scalp’s surface.
• Tea tree oil: This natural essential oil has antibacterial properties that can help clean and reduce oiliness across the scalp.
• Nettle extract: This active ingredient can prolong hair's freshness and help to regulate sebum production, reducing excess oil.
• Charcoal: A natural detoxifier, this will help absorb excess oil and impurities from the hair and scalp.

There are also certain ingredients in shampoos that you should avoid if you are prone to greasy hair. Here are the ingredients to avoid:

• Silicones: These can create a build-up on your hair and scalp, trapping product and dirt in and leading to greasiness.
• Sulphates: Our expert Luke Benson emphasises the importance of avoiding sulphate-based shampoos as they can ‘strip the hair of its natural oil, encouraging it to produce more to compensate.’
• Fragrances: They may smell nice, but be wary of fragranced shampoos - they can often contribute to oiliness across the scalp.
• Oils: Added oils such as coconut oil and jojoba oil may contribute to greasiness.

The benefits of using specific shampoos for greasy hair

Using a specifically formulated shampoo for greasy hair, with ingredients to help prevent oil build-up and encourage healthy locks, can offer a host of positive outcomes. These include:

• Regulating the production of sebum in the scalp and hair, reducing oiliness
• Absorbing excess oil in the hair and scalp without stripping away natural oils
• Exfoliating the scalp to remove any build-up
• Nourishing and refreshing the scalp with natural ingredients to prevent damage and keep hair healthy

How often should you wash greasy hair?

How often you wash greasy hair depends on several factors, including your hair type, lifestyle and personal preferences. In general, it’s recommended to wash greasy hair no more than every other day - over-washing can strip your scalp of natural oils and lead to increased oil production. Here are some factors to consider to help guide you in your hair-washing frequency:

• Type of hair: Whether your hair is thick, thin, straight or curly can contribute to how often you feel the need to wash your hair. Thinner hair may need washing more frequently to prevent the build-up of grease, while thicker, curlier hair may be able to go longer between washes.
• Activity: If you exercise regularly, you may need to wash your hair more frequently to avoid increasing oiliness.
• Climate: In hot, humid climates, you may need to wash your hair more frequently to keep cool but also keep your hair clean.
• Styling products: If you use a lot of styling products, washing your hair more regularly may be needed to remove any residue build-up.
