There’s a lot of mixed messages regarding Mineral Oil and hair products. In addition to product build up, there’s even quite a number of sites who are speculating that it’s carcinogenic.
It’s also an ingredient added to many dandruff shampoos. And in true Dandruff Deconstructed style, we thought it was time to get to the bottom of the Mineral Oil discussion, lay out the facts and, if needed, recommend the best Mineral Oil free dandruff shampoos on the market today.
In this article:

- What are the best Mineral Oil free dandruff shampoos?
What is Mineral Oil?
Mineral oil is a by-product of petroleum, added to shampoos as a lubricant. It can be sold under a range of different names, including paraffin oil, liquid paraffin, liquid petroleum, and baby oil. It is one of several oils commonly added to shampoos as lubricants, others you might see include: sunflower, coconut, olive, and ricebran .
Around 4,000 million tons of mineral oil are produced every year, although the majority is used for other applications, such as lubrication in electrical and chemical engineering; pharmaceutical manufacturing; and food preparation . It’s created from the distillation of crude oil, using heat and catalysts to remove the longer chain hydrocarbons (which are used primarily as fuel).
Note: Depending on which country you live in, the different names for mineral oil can describe different hydrocarbon compositions, although they will carry out the same function in shampoos.
What is it used for?
What are the risks?
Mineral oil is widely used in a range of commercial products and can be readily bought from pharmacies and supermarkets in most countries. The World Health Organisation has concluded that mineral oil is not likely the be harmful or a carcinogen . Even when ingested directly as a short-term laxative, the most common adverse effect is ‘lipoid pneumonia’ – or accidental inhalation .
While mineral oil is generally considered to be safe and effective – despite being directly refined from petroleum – its long-term effects on hair aren’t so clear. It has been suggested that frequently using an oil-based shampoo might lead to dry, brittle hair or dry scalp when the shampoo is withdrawn. Petroleum isn’t water soluble, so there is a risk of scalp build up if the ingredient isn’t washed away using an effective surfactant. However, in its purest form, it is non-comedogenic. But it can trap comedogenic ingredients in pores.
Are there any alternatives?
Mineral oil is widely used because it’s safe, cheap, and effective at restoring damaged hair, but alternatives are available. These can be split into two categories, those derived from linoleic acid and those based on lauric acid – each with subtly different properties .
1. Coconut Oil
The principle fatty acid in coconut oil is a triglyceride of lauric acid, which has been shown to be more effective at treating damaged hair than mineral oil. Coconut oil contains small molecules, which can easily penetrate hair fibers, improving water retention and decreasing protein loss. Coconut oil based shampoos are generally more expensive and will solidify at room temperature unless additional ingredients are added to modify the melting point.
2. Sunflower Oil
Sunflower oil is comprised of a triglyceride of linoleic acid, derived from vegetable sources. It’s the least effective of the three oils because its bulky molecular structure prevents hair fiber penetration – although will still coat hair improving water retention. Sunflower oil is commonly used despite being less effective because it’s more ‘natural’ than mineral oil and cheaper than coconut oil.
The 15 Best Mineral Oil Free Dandruff Shampoos
Pharmaceutical Specialties formed in 1974 to “start a company to make better products than were commercially available for people with sensitive skin”. And boy, have they achieved it with this Free and Clear shampoo.
What is perhaps surprising on a website dedicated to dandruff treatments is that this isn’t a dandruff shampoo at all.
It’s rather a "a non-medicated, mild shampoo for sensitive skin and scalp.”
That said, we can’t use a medicated shampoo all the time, and this is my go to shampoo for those “between” washes.Read the entire review

Designed to treat Dry Scalp
This dry scalp treatment isn’t a shampoo at all, but rather a leave on moisturizer that you apply to your hair after washing.
The advantage of this approach is that, while shampoos are designed to clean (and all the sensitizing issues that come with that) this treatment is designed to moisturize and nothing else.
You’re free to use the shampoo of your choice and us this treatment in combination.
It’s an excellent approach that I hope other manufacturers take notice of.Read the entire review
