Teenage dandruff is common, particularly during puberty. If you've suddenly started noticing white flakes in your hair, an itchy scalp or dandruff on your school uniform, you're definitely not the only one.
And if you're a parent wondering why your 12, 13 or 14-year-old has suddenly developed dandruff, there's a good scientific explanation.
Hormonal changes during puberty can increase the amount of oil your scalp produces. This can create conditions that make dandruff more likely, even if you've never experienced it before.
The good news? Teenage dandruff can usually be managed with the right scalp-care routine.
Why do teenagers get dandruff?
The teenage years bring plenty of changes. Spots, greasy hair, body odour and growth spurts are all part of puberty. But one change that doesn't get talked about nearly enough is dandruff.
During puberty, rising hormone levels stimulate the sebaceous glands in your skin. These glands produce a natural oil called sebum.
Your scalp contains lots of sebaceous glands, which explains why hair can become noticeably greasier during adolescence.
But there's another part of the story.
Your scalp is home to a community of microorganisms, including a naturally occurring yeast called Malassezia. This yeast interacts with oils on the scalp, and some people are particularly sensitive to the substances produced during this process.
The result can be irritation, changes in skin-cell turnover and the familiar flakes associated with dandruff.
A 2025 scientific review published in Pediatric Annals discusses how seborrhoeic dermatitis, a condition closely related to dandruff, can affect people from adolescence into adulthood.
Further research, including a comprehensive review of dandruff and seborrhoeic dermatitis, explains the relationship between sebum production, Malassezia and individual scalp sensitivity.
In other words, puberty can change your scalp environment, making dandruff more likely to develop.
Can puberty cause dandruff?
Yes. Although puberty isn't the only cause of dandruff, hormonal changes are one reason dandruff commonly starts during adolescence.
Think of it a little like teenage acne.
Hormones can increase oil production in the skin. On your face, that may contribute to spots. On your scalp, increased sebum can influence the environment in which dandruff develops.
However, not every teenager with greasy hair will get dandruff.
Individual scalp sensitivity, skin-barrier function and the scalp microbiome also matter.
A 2013 review of dandruff pathophysiology describes how microbial activity, sebum and individual susceptibility interact in the development of dandruff and seborrhoeic dermatitis.
And having dandruff doesn't mean there's anything wrong with your hormones.
Is dandruff normal in 12, 13 and 14-year-olds?
Yes. Dandruff can appear around the time puberty begins, although the age at which it starts varies from person to person.
Dandruff in 12-year-olds
Some children begin puberty before their teenage years. As scalp oil production increases, dandruff may become noticeable for the first time.
However, not every flaky scalp is dandruff. Eczema, psoriasis, product irritation and scalp infections can cause similar symptoms.
Dandruff in 13-year-olds
At 13, hormonal changes can make greasy hair and dandruff more noticeable. This can be frustrating, particularly when flakes show up on dark school uniforms or clothing.
Regular washing and an appropriate anti-dandruff treatment can help, but check the product's age guidance before use.
Dandruff in 14-year-olds and older teenagers
By 14, some teenagers are experiencing more persistent oily scalps, while others have very little change.
Dandruff may fluctuate over time and can sometimes worsen with stress, cold weather or irritating hair products.
Whether you're 12, 14 or 17, the important thing is to identify what's causing the flakes and choose an appropriate treatment.
How to get rid of teenage dandruff
There isn't a guaranteed overnight cure for dandruff, but most cases can be managed effectively.
1. Choose an appropriate anti-dandruff shampoo
Ordinary shampoo removes dirt, sweat and some visible flakes. Anti-dandruff shampoos contain ingredients designed to address factors involved in dandruff.
Common ingredients include:
- Piroctone olamine: An ingredient used in cosmetic anti-dandruff shampoos to help control dandruff-associated microorganisms.
- Ketoconazole: An antifungal ingredient found in medicated dandruff shampoos. Good for a 'quick fix' in the fight against dandruff, but may be too strong for daily use.
- Salicylic acid: Helps loosen and remove accumulated scales.
- Coal tar: Used in some scalp treatments to help manage scaling.
Research has investigated the effectiveness of different anti-dandruff ingredients. For example, a randomised clinical trial compared a shampoo containing piroctone olamine and salicylic acid with a zinc pyrithione shampoo.
Not every product is suitable for every age group. Younger teenagers and their parents should check the label or ask a pharmacist before choosing a treatment.
2. Wash your scalp regularly
Teenage hair can become oily quickly, particularly after sports, exercise or physical activity.
Regular washing can help remove excess oil and visible flakes.
How often you need to wash depends on your hair type, scalp condition and the shampoo you're using. Some teenagers may prefer frequent washing, while those with curly, coily or dry hair may need a different routine.
Follow the instructions on your anti-dandruff shampoo rather than assuming that more washing always means better results.
3. Focus on your scalp, not just your hair
Dandruff starts on the scalp, so that's where your shampoo needs to reach.
Gently massage shampoo into your scalp with your fingertips, paying attention to areas where flakes are most noticeable.
Avoid scratching with your fingernails, which can make irritation worse.
4. Give your treatment time to work
Dandruff doesn't always disappear after one wash.
Improvement may take several weeks, depending on the treatment and severity of symptoms.
Follow the product instructions and ask a pharmacist if you're unsure how frequently to use it.
5. Be careful with styling products
Hair gels, sprays, waxes and fragranced styling products can sometimes irritate the scalp or leave residue that looks like flakes.
If your scalp becomes itchy after using a new product, stop using it and see whether the irritation improves.
What's the best anti-dandruff shampoo for teenagers?
The best shampoo depends on the teenager's age, scalp symptoms, hair type and sensitivity.
Look for a product that:
- Contains an established anti-dandruff ingredient.
- Is appropriate for the user's age.
- Has clear instructions for frequency of use.
- Works with their hair type and normal styling routine.
- Doesn't leave their scalp feeling unnecessarily irritated.
One particularly interesting area of research involves piroctone olamine, an ingredient used in cosmetic anti-dandruff formulations.
A 2024 study published in the International Journal of Cosmetic Science investigated scalp microbiome changes following treatment with a shampoo containing 0.5% piroctone olamine.
The researchers reported changes in scalp microbial communities alongside improvements in dandruff-related measures.
More recent research, including a 2025 randomised controlled study of an anti-seborrhoeic dermatitis shampoo, has also explored the relationship between scalp microbial balance and clinical improvements.
These studies provide useful evidence about anti-dandruff formulations, although they do not establish that every product containing the same ingredient will perform identically or that the tested formulations are suitable for every teenager.
At Hairetic, we believe having dandruff shouldn't mean having to compromise on the rest of your haircare.
Our Anti-Dandruff Shampoo contains piroctone olamine alongside aloe vera and selected botanical extracts, in a formula developed with scalp care and hair feel in mind.
For younger users, always check the product's age suitability before use.
Can teenagers get dandruff from not washing their hair?
No. Dandruff is not caused by poor hygiene.
This is one of the biggest misconceptions about dandruff, and an important one to clear up.
Someone who washes their hair every day can still have dandruff. Someone who washes less frequently may have no dandruff at all.
Washing less often can sometimes make flakes and scalp oils more noticeable, but it doesn't mean the person is dirty.
So if you're a teenager dealing with dandruff, don't assume you're doing something wrong.
Is it dandruff, dry scalp or something else?
Not all flakes are caused by dandruff.
Dandruff: Often involves visible white or yellowish flakes and an itchy scalp. It can occur alongside greasy hair.
Dry scalp: Can produce small flakes and a feeling of tightness or dryness, particularly after irritating products or harsh washing.
Product irritation: May cause itching, redness or flaking after introducing a new shampoo, hair dye or styling product.
Other scalp conditions: Eczema, psoriasis and fungal infections such as scalp ringworm can also cause scaling.
Research into the pathophysiology of dandruff and seborrhoeic dermatitis highlights the importance of scalp-barrier function and inflammatory responses, helping explain why different scalp conditions may produce similar-looking flakes.
If there are painful patches, broken hairs, patchy hair loss, thick crusts or significant inflammation, speak to a GP rather than assuming it's ordinary dandruff.
Can teenage stress make dandruff worse?
Potentially, yes.
School exams, friendship problems, poor sleep and everyday teenage pressures can all contribute to stress.
Stress is recognised as a possible factor in worsening seborrhoeic dermatitis symptoms, although it isn't the sole cause of the condition.
Getting adequate sleep, managing stress and following a consistent scalp-care routine may help with overall wellbeing and make dandruff easier to manage.
Does teenage dandruff go away after puberty?
Sometimes symptoms improve as people get older, but dandruff doesn't necessarily disappear when puberty ends.
For some people, dandruff comes and goes throughout adulthood. Others experience occasional flare-ups, particularly during colder months or stressful periods.
The goal is usually to manage the condition rather than expect a permanent cure.
Teenage dandruff and confidence
Let's talk about something that matters just as much as the flakes themselves.
Being a teenager can already feel like everyone is looking at you. Adding an itchy scalp or visible dandruff to the mix isn't particularly welcome.
White flakes on a black school jumper, worrying about someone noticing your shoulders, or feeling uncomfortable when a friend looks at your hair can affect confidence.
But dandruff is common, and it isn't a reflection of how clean you are or how well you look after yourself.
If you're a parent, treating dandruff as an ordinary scalp condition rather than something embarrassing can make a real difference.
And if you're a teenager reading this, remember: your scalp is not the problem. It's simply something you may need to learn how to look after.
When should a teenager see a GP about dandruff?
Most dandruff can be managed with appropriate over-the-counter treatment, but seek medical advice if:
- Dandruff hasn't improved after around four weeks of appropriate shampoo treatment.
- The scalp is very itchy, red, swollen or painful.
- There are thick crusts, sores or areas of hair loss.
- There are flaky or inflamed patches on the face or elsewhere on the body.
- Symptoms are getting worse despite treatment.
A GP can check for other scalp conditions and recommend suitable treatment.
Frequently asked questions about teenage dandruff
Why does my teenager suddenly have dandruff?
Puberty increases scalp oil production, which can influence the activity of naturally occurring scalp microorganisms such as Malassezia. This can make dandruff more likely to develop during adolescence.
Is dandruff common in 13-year-olds?
Yes. Dandruff often begins around puberty and can affect 13-year-olds. However, persistent or severe flaking should be assessed to rule out other scalp conditions.
Can a 12-year-old use anti-dandruff shampoo?
Some anti-dandruff shampoos may be suitable, but age restrictions vary between products. Check the label and ask a pharmacist or GP if you're unsure.
Does puberty cause an itchy scalp?
Hormonal changes during puberty can increase scalp oil production and contribute to dandruff, which may cause itching. However, allergies, eczema and other conditions can also cause an itchy scalp.
How long does teenage dandruff last?
Dandruff may come and go. Appropriate shampoo treatment can often improve symptoms within several weeks, but some people need ongoing scalp care to keep dandruff controlled.
Is teenage dandruff contagious?
No. Ordinary dandruff is not contagious and cannot be passed between friends or family members.
Can teenage dandruff cause hair loss?
Ordinary dandruff does not usually cause permanent hair loss. However, persistent scratching can damage the scalp, and some other conditions that cause flaking can also cause hair loss. Seek medical advice if you notice thinning or bald patches.
The Hairetic verdict
Teenage dandruff is common, understandable and usually manageable.
Puberty can change your scalp's oil production, making dandruff more likely. But that doesn't mean you have to put up with uncomfortable itching or visible flakes.
Choose an age-appropriate treatment, establish a scalp-care routine and give it time to work.
Because teenage life has enough complications already. Your shampoo shouldn't be another one.
