Oily hair is one the most common hair conditions around – and while a lot of people can easily hide it by tying their hair up, not everyone has that ability. And even if you can, sometimes you just want to wear your hair down.
Despite it being so common, oily hair can still cause serious confidence issues, as well as making it difficult to manage your hair on a day-to-day basis.
In this blog, I’ve discussed what causes oily hair and the different approaches you may need to take to solving the issue before listing a few of my favourite products used to treat oily hair.
Read on for more.
What causes oily hair?
Excessively oily or greasy hair is caused by overactive sebaceous glands. These glands produce an oil called sebum, which is necessary for healthy hair. However, some people’s are a little too active, meaning they produce more sebum than required and their hair gets greasy.
You could be suffering from oily hair for a variety of reasons:
Every time you wash your hair, your scalp will get the message to produce more sebum, this means that washing your hair too often results in your scalp producing too much sebum and your hair getting progressively oilier. This commonly leads to a vicious cycle wherein people start getting slightly greasy hair, so they start washing it more to resolve the issue not knowing it’s actually making things worse.
I’d always recommend checking this isn’t the case before going out and buying a range of products, because you might just get lucky and sort your problem out for free!
If you’re currently washing your hair every day, try cutting back to every other day to give your scalp time to breathe. After a few weeks, once your body has adapted to the new routine, you may find your hair starts becoming less greasy on its own. This can be frustrating to try, but your bank account will thank you if it proves to be the correct move.
Although everyone can suffer with greasy hair, it’s most common on people with straight hair.
Your hair shaft being perfectly straight makes it easy for the oil to slide down and disperse all over your head, meaning you’ll typically have to wash your hair more often and it will be more prone to getting excessively oily.
Alongside this, it’s also much more noticeable when straight hair is greasy compared to other hair types, meaning your hair may not be as greasy as your curly haired friend’s but could look a lot worse.
Although it may not be the sole cause of your problems, your diet can play a key role in your hair being oilier than you’d like. Having a diet high in refined carbohydrates and saturated fats can make your skin produce more oil – this includes the sebum which results in greasy hair.
Sudden changes in environment or temperature leads to your body adapting in a variety of wonderful ways you often won’t even notice. Unfortunately for your hair, one of these can be to increase sebum production in an effort to protect your scalp.
So if you go and stay somewhere with a vastly different climate to what you’re used to, or get hit by a sudden heatwave or cold snap, you may notice your hair getting greasier as your body adapts to the changes.
Alongside being affected by changes in weather, temperature as a whole can have an impact. For example, many people start noticing their hair getting oilier in the winter months as they constantly transition from a freezing cold outside to a warm, heated inside.
Puberty, pregnancy, giving birth and more result in significant hormonal changes in your body, all of which can have the side effect of making your hair greasier than it was previously.
When your body is undergoing such a dramatic change, it’s undergoing a lot of stress both on the surface and behind the scenes, and one of the most common issues during these times is an increase in oil production.
If you feel this may be the cause for your hair troubles, we’d recommend seeing a doctor to discuss your issues before making significant changes.
Have you recently got yourself a shiny new conditioner or hair treatment to give your locks a bit more life but noticed your hair is getting oily? Make sure you only apply them to the ends of your hair. Going all the way to the roots will trap the oils, resulting in your hair looking weighed down and greasy.
Additionally, if you’re using gel or an alternative styling product, make sure you wash them out thoroughly. It’s quite common for people to give their hair a quick rinse when rushed for time, which leads to the product building up in your hair and making it greasy.
Of course, for some people, the answer to the question “why is my hair so greasy?” is a simple one: genetics.
If one of your parents or relatives have naturally oily hair, there’s a very good chance you’re just genetically predisposed to produce more sebum than the average person and will always have hair which gets oily faster than most. This isn’t the end of the world, however. A good hair care regime could work wonders!
