Could your hair serum be causing dandruff?

Hair serum is a widely used hair care product that promises to revitalize your hair. But how does it affect dandruff? Our guide gives you the answer plus some handy tips to make sure you stay flake-free.

Silicone- or oil-based hair serums are a great way to detangle and soften hair while giving it a lustrous shine. But could they be a culprit for dandruff?

The short answer is ‘no’, but it’s actually a little more complicated than that.

Building up and breaking down

There are two main problems with constant use of a hair care product like serum – build-up and breakdown.

The silicone and oil-based coating that’s found in many hair serums tends to stick. This means that if you apply it near your roots, it can easily build-up on your skin, along with your natural scalp oils.

This build-up mixture can damage your scalp if it is not washed out properly.

That’s because it breaks down over time into potentially irritating substances. As they irritate your scalp, they can make your dandruff appear worse.

It’s important to take steps to minimize both build-up and breakdown. Luckily, they can both be fixed at the same time.

Washing your hair properly and regularly will ensure that serum doesn’t have a chance to become a problem. Just remember:

  • wash your hair regularly to clear build-up

  • ensure that you wash your hair properly, rinsing thoroughly to clear your hair of shampoo

  • a good conditioner will moisturize your scalp and hair, keeping them healthy


Dealing with dandruff is as easy as using a clinically proven shampoo and conditioner to fight the symptoms and causes of the problem.

Before adding a serum, make sure your scalp is in good shape.

Use your dandruff shampoo every time you wash for at least two weeks (ideally every day). At this point, you’ll be able to switch to a maintenance routine, washing two or three times a week.

Using these tips, you can easily add a serum to your routine while enjoying great, dandruff-free hair.
