Why Does My Scalp Smell Even After I Wash It? If You, Too, Are Tired Of Your Hair Smelling Like A Wet Dog, It’s Time To Finally Fix It.
Do you, too, think that the only parts that can smell are your underarms or feet? Yes, they are stinky, but apart from these, your scalp and hair could even smell worse if not taken care of properly.
Now I know that smelly hair can be embarrassing, but you should also know that it is a really common thing that most people go through at least once in their life. Especially children since they are always playing and sweating.
And to tackle the question of “Why does my hair smell bad even after washing” you need to find the reasons behind the issue and then shoot it one by one with the solutions.
Don’t worry, I have been there with stinky, moldy hair and didn’t know what to do. I can guarantee that it is a matter of a few treatments and you’ll soon say goodbye to a smelly scalp.
What Causes A Smelly Scalp?
The very first thing you need to do is to learn why exactly you have smelly hair. Now there can be more than one cause, so don’t worry and keep a note because we are going to treat them after.
1. Seborrheic Dermatitis

You may not have heard of this particular term, but I’m sure you might have either faced this problem or heard someone going through it.
Seborrheic Dermatitis is a common skin condition that mainly affects your scalp but can also be on the face and upper body where sebaceous glands can produce oil. It actually causes scaly red patches and stubborn dandruff. Which can produce that wet dog smell in your hair.
2. Excessive Sweating
Some people like me naturally are very sweaty. While some people may be working out a lot. But if you are not properly cleaning your hair often, that sweat in your hair can be a nice breeding ground for bacteria on your scalp. And if your shampoos are not cleaning off that bacteria, it may become the reason why your hair smells bad even after washing.
3. Seasonal Changes
Some of you might experience smelly scalp if you live in a humid area or especially during the monsoon season. It is because the humidity in the environment gives birth to microbial growth that can cause a smell.
4. Fungal Infection
There is a possibility that a fungus living on the scalp is causing the smell. As a result, people may suffer from inflammatory reactions like dandruff or eczema.
5. Unhygienic Hair Habits

Are you guilty of washing your hair with hot water? Or wearing a cap or scarf for too long that it starts to produce excess sweat in your hair? Or maybe skipping your hair wash days because you are too lazy or busy? Those are some of the habits that can trigger smelly hair and you need to stop them today.
6. Sleeping In Wet Air
I personally have been guilt-ridden about this. I have long wavy hair, and I would sometimes wash my hair at night if I had an important day. But that’s so wrong, and here’s why.
Oftentimes, mildew in hair or fungus is a problem for girls with curly, coily, wavy, or locked hair. Mildew is a fungus that grows on surfaces, usually gray or white in color, and is often found in damp or moist conditions. It smells musty and can be found in your home, on fabric, and yes, even on your scalp and hair. The problem is often caused by wet hair not having been allowed to dry for prolonged periods of time.
5. Apple Cider Vinegar
Apple cider vinegar has a special place in my kitchen for its anti-microbial properties and ability to help in weight loss, lower blood sugar levels, improve digestion, lowering cholesterol, and other infinite uses.
And that’s why it has been proven beneficial for treating dandruff or the smell. But beware that it is a really strong product, so never use it without diluting it with equal parts of water.
6. Do Not Sleep In Or Tie Wet Hair
It is highly recommended to air-dry your hair before going to bed and avoid tieing them into a bun or pony when they are wet. I would not recommend blow-drying because it can be insanely harmful in the long term, but if it’s urgent and you don’t have time, it can work.
Tips To Prevent Your Hair From Smelling Bad

- Use chemical-free, sulfate-free hair products.
- Don’t let excessive sweat build up in your hair, so try washing it frequently.
- Do not sleep or tie your hair when they are wet. Let them air-dry first.
- It is advisable not to scratch your scalp frequently as it leads to excessive shedding of dead cells, which, in turn, increases the risk of microbial infection.
- Regular physical workouts and meditation can help you manage stress levels.
Why Does My Hair Smell Bad Even After Washing?
Your hair can smell bad even after washing them because of different reasons like seborrheic dermatitis, excessive sweating, fungal infection, seasonal changes, mildew in hair, stress, improper diet, sleeping in wet hair, and other factors. So you need to solve the problem thoroughly because shampoos that smell good are just not enough to get rid of smelly hair.
Why Does My Hair Smell Bad So Quickly?
It could be that you have an oily scalp, which can cause your hair to become greasy and start to smell bad quickly. You may also have a build-up of products in your hair, which can lead to bad smells. If you’re using a lot of styling products, such as hairspray, gel, or mousse, try washing your hair more often to prevent the build-up. Try to limit the use of dry shampoo and start using a clarifying shampoo to remove any product build-up to get rid of that smell.
