Getting the most out of your derma roller is important for effective hair treatments. While it may seem like an extra step, cleaning your derma roller regularly is essential for preventing bacteria buildup.

In this guide, we'll show you how to clean your derma roller in a few simple steps. With just a few minutes of your time and the right cleaning supplies, you can keep your derma roller in top condition for effective hair treatments. Read on to learn more!

Why you need to clean your derma roller

Cleaning your derma roller is especially important if you use it for your hair. The micro-needles in the roller can puncture your scalp’s layers, and if the roller is not cleaned correctly, it can lead to a buildup of bacteria.

This bacteria can lead to issues such as rosacea, eczema, and melasma.

Rosacea causes your skin to become red and bumpy; eczema results in skin irritation and inflammation; and melasma is a form of pigmentation caused by a hormonal imbalance.

Therefore, it is important to clean your derma roller before and after using it to prevent these unnecessary complications.

How to clean a derma roller before using it?

Here is a step-by-step guide on how to properly clean a derma roller before using it:

  1. Gather the materials needed: rubbing alcohol, clean glass, and your derma roller.
  2. Pour some rubbing alcohol into the clean glass and submerge the derma roller’s head in the glass for 3-5 minutes.
  3. Remove the sterilized derma roller from the glass and allow it to dry for at least 10 minutes.
  4. To dry, empty the cup and place the derma roller upside down for 10 minutes.
  5. Once it's completely dry, your derma roller is sterilized and ready to use. Be sure to do this each time you clean your derma roller.

Finally, never share your derma roller with anyone else, as this can spread bacteria and cause skin damage. Make sure to clean your derma roller properly after each use to ensure its longevity and effectiveness.

How to clean a derma roller after using it?

Here is a step-by-step guide on how to clean the derma roller after use:

  1. Disinfect the roller head with alcohol – After each use, it is essential to disinfect the derma roller's head with 70% isopropyl alcohol. This will help to keep it sterile and prevent any potential infections when using the roller again later.
  2. Rinse with warm water – After disinfecting the roller head, rinse it thoroughly with warm water and use a soft toothbrush to remove any leftover residue.
  3. Dry the roller head – Once it is cleaned, dry it out thoroughly with a clean towel.
  4. Store in a cool, dry place – When not in use, store the derma roller in a cool and dry place. This will help to keep it in good condition for longer.

These steps should be followed every time you use the derma roller to ensure it is always kept clean and free from bacteria. 

This will help minimize the risk of infection and ensure you get the most out of your derma roller experience. With regular cleaning, you can be sure of achieving the best results!

How often should you clean your derma roller?

When it comes to cleaning your derma roller, you should clean it before and after each use. This is especially crucial if you're derma rolling over sensitive areas.

In addition, if you use your roller often, it's recommended that you clean and sterilize the device after every few uses. It's also important to note that the frequency with which you should clean your derma roller depends on the size and length of the needles you use.

For example, cleaning the device after each use is worthwhile for maximum effectiveness if you have a derma roller with longer needles. On the other hand, if you have a derma roller with shorter needles, it can be cleaned after every few uses.

Regularly cleaning your derma roller ensures that it's free of debris and bacteria, which helps keep your skin healthy.

When it comes to cleaning your derma roller, there are certain things you should avoid. These include:

  • Sterilizing machines
  • Chloroxylenol
  • Denture tablets
  • Dettol
  • Bleach
  • Boiling your derma roller

Using any of the above can have unintended consequences, like dissolving the glue that holds many metal microneedles in place. This can result in needles falling out, which can be dangerous and potentially lead to skin damage. 

It's best to stick with gentle cleaning methods as outlined in this guide. Doing so will ensure that you get the best results from your derma roller and maintain its longevity.


Cleaning and maintaining your derma roller is key to getting the most out of it. With regular cleaning, you can ensure that your device is free from debris and bacteria, so you can get the best results.

Remember to use only gentle methods when cleaning your derma roller, such as those outlined in this guide, and avoid any harsh chemicals or boiling. With the proper care, you can ensure your derma roller is always in tip-top shape!

For the best results, you can also invest in a derma roller specifically designed for scalp treatments, like the Scandinavian Biolabs Scalp Activation Roller.

This roller is easy to clean and use and encourages overall scalp support for healthier and fuller-looking hair. With the right care and maintenance, your derma roller will stay in great condition, and you can look forward to beautiful results.


Can I clean a derma roller with boiling water?

No, we don't recommend cleaning a derma roller with boiling water, as this may cause damage to the needles. It's best to use a disinfectant alcohol solution and warm water instead.

Can I clean a derma roller with Dettol?

No, using Dettol to clean your derma roller is not recommended. It contains a mid-range toxic chemical that can cause burning, itching, rash, redness, or swelling.  It can also be dangerous to pets and may dissolve the glue in metal rollers, causing them to fall apart. It's best to find an alternative cleaning method.

Can I use a disinfectant spray on my derma roller?

You can use an alcohol-based disinfectant spray to clean your derma roller. Make sure to thoroughly rinse off the disinfectant after use and pat the roller dry with a clean cloth.

Can I clean my derma roller in the dishwasher?

No, cleaning your derma roller in the dishwasher is not recommended. The intense heat and abrasive detergents may damage the device and make it less effective.
