Whenever we come to develop a product, your safety is always our number one priority. It’s our guiding principle from the moment we have the idea for a product right the way through to when you use it.


Safety from the start

So, let’s start at the beginning. When Head & Shoulders was first developed in 1961, it came after ten years of research and the screening of over 1,000 materials and numerous clinical studies.

Technology has changed a bit since the sixties, but our commitment to scientific research has not. Since 1961, we’ve researched tirelessly to find ways to improve our formula and give it additional features that make it even better for you to use.


When examining ingredients to include, the first thing we do is establish its safety record. We use a four-step, science-based process to ensure both your safety and the safety of our products before they go to market:

  1. Before any ingredient goes into our shampoos and conditioners, we gather all the relevant safety and toxicity information on the ingredient. If we have any doubt whatsoever about an ingredient’s safety and benefit to consumers, we won’t use it.

  2. Once an ingredient has passed our first test, we define a ‘safe range’ – the quantity that is safe to include within our product – using the same scientific process as the FDA, EPA, WHO and EU among others. If we can’t define the ‘safe range’, then the ingredient doesn’t make the cut.

  3. Evaluating each ingredient individually isn’t enough, so we also double check the final formula of our product, to make sure the safe range is met during use. If we can’t conclude the product formula is safe, we will either reformulate or decide not to market the product.

  4. Even after the product hits the shelves, we continuously monitor consumer use and any new scientific information that comes out about the ingredients, working with external scientists and regulatory agencies to make sure our safety methods are always up to date.

Proven to work

Each of our ingredients is combined in a precise, pH balanced formula which protects your scalp from the root causes of dandruff - not just the symptoms - to help keep flakes from coming back.

In fact, we were the first brand to crack the genetic code of Malassezia globosa, the dandruff-causing fungus present on everyone’s scalp.

That means we understand the root cause of dandruff better than anyone, and can apply this scientific knowledge to improving our products.

The standards we set for ourselves are high, because your safety depends on them. We’ve conducted more than 225 clinical studies at independent facilities around the world to make sure our products are both safe and effective.

That’s why consumers trust Head & Shoulders – and why we are the number 1 shampoo in the world.
