If something is said often enough, even by one person, then others will start to believe it to be true. Over time this will lead to more people believing it and this is how myths are generally born. In many cases, the myths are based on a partial truth. But, the advice provided is often more harmful than beneficial.

1. Activated Charcoal Removes excess Oil

If you look at a host of skincare and haircare products you are likely to find many of them contain activated charcoal. It is believed that this substance is effective at removing toxins from your skin.

The theory is based on the fact that activated charcoal is extremely porous. Thanks to heat treatment, the activated charcoal has a large surface area and is effective at absorbing substances.

So far so good!

The problem is that charcoal is indiscriminate. It will absorb everything from your skin, good and bad. In short, if you want to maintain the complex structure that allows your hair to thrive, you need to skip activated charcoal products and stick to natural ones, such as those created by Kevin Murphy.

2. Being Vegan Is Bad for your Hair

This myth arose because of the perception that vegans, and even vegetarians, were missing out on essential nutrients. In particular, animal fats and protein which are essential to the health of your hair.

However, the truth is that as long as you consume a balanced diet with protein, carbohydrates, healthy fats, and fruit, your hair will have everything it needs to stay healthy. 

3. Shaving Your Hair Helps It Grow Thicker And Stronger

This myth is potentially the most surprising and damaging. Shaving your hair can cause scalp irritation and this is likely to cause your hair to thin, instead of getting thicker.

The simple truth is that every strand of hair is created in a follicle on your head. It grows from this follicle, the root of your hair, and continues to grow throughout its life cycle. The presence or lack of hair on your head makes no difference to how the follicle grows.

4. Avoid Going Outside With Damp Hair

This is one myth that most people heard when they were young and they probably pass on to their own children. The theory is that because your hair is damp you are more likely to be cold and, therefore, catch a cold.

However, a cold is a virus, and having damp hair will make no difference to whether you contract a virus or not. 

5. Stress Turns Your Hair Grey

You’ve probably heard this one multiple times. The simple truth is that most people go grey as they age. It’s a fact of life, a result of genetics and the amount of pigmentation your follicles have. There is a limited supply and, once it has gone, your hair will start to change colour. It is that simple and has nothing to do with stress.
