Sometimes it is tough. You may feel like your life is so messed up since you started losing your hair. This also causes psychological problems for many people as they may feel self-conscious, unattractive, or that they are getting old, and it’s even worse for the people who experience loss of their hair when they are still relatively young.

There are so many options out there as a solution for hair loss, such as home remedies, creams, sprays, therapies using laser devices , etc. This leaves many people who are trying to fix their problem confused and a little lost.

Perhaps you have tried all the treatment methods of hair loss at your disposal but you still aren’t getting the results you have so long desired.

But are you supposed to give up just yet? Of course not. Especially, not when you haven’t tried using dermaroller.

You know, it doesn’t suffice to give up on hair loss treatment just because one method didn’t work for you. There are several other treatment strategies.

In this article, we are going to explore one of the favorite hair regrowth technique that has yielded immeasurable results for countless individuals who had been previously battling hair loss – the dermaroller. But what is a dermaroller? How does it work? Is it really effective for treating hair loss? Read on:

What is a dermaroller?

Dermaroller is a hand-held plastic device with a cylinder roller that is covered with tiny micro-needles which are usually made of titanium.

The needles are used to make tiny pinpricks into the skin. The pricks penetrate into the dermis just deep enough in depths sufficient to stimulate the production of new cells and boost circulation albeit without causing skin damage or intense pain.

This device not only treats hair loss by inducing the production of collagen in the skin, but it also is excellent for eliminating imperfections on the skin. Micro-needling treatment can be done simply at home, but sometimes is done by a medical professional, such as a dermatologist.

Does the dermaroller really work?

The short answer to this question is Yes! Dermaroller works.

But the long answer is something like this:

Upon looking into the customer reviews for this product, it seems that many have had extraordinary and life-changing results. On the other hand, it hasn’t worked for everyone.

Like all treatments, the effectiveness of dermaroller varies from one user to another. It also depends on how experienced a person is in using a dermaroller.

Using the dermaroller has proved that it is very effective in treating hair loss through clinical research, studies, and trials. It is safe for your scalp and hair, as well as the rest of your body, and was also proven to be more effective when pairing with a hair loss medication.

It helps to preserve the hair that is already there while stem cells are produced into the skin, increasing the growth of your hair.

Despite its appearance, it is a very productive tool when it comes to tackling the challenge of stopping hair loss. And despite the fact that there are different conditions of hair loss like alopecia areata, androgenic alopecia (AGA) or the most difficult case called alopecia totalis, fortunately for you, the dermaroller is likely to benefit you regardless of what may be causing your hair loss.

However, upon studies on the record about the use and results of dermaroller, out of three hair loss types mentioned before, the micro-needling treatment is considered to be working best for those suffering from androgenic alopecia.

Research published in the Indian Journal of Dermatology states that micro-needling addition to the current patient’s treatment plan shows significant results and new hair growth can start after 8-10 sessions.

All in all, in most cases, users have given reports confirming the effectiveness of this skin needling procedure. Frankly, I haven’t seen someone who has tried this method and failed to achieve any results at all.

What is the mechanism behind micro-needling?

These are the main four points describing how dermarolling benefits your hair:

  • it triggers the body’s natural reaction to initiate the wound healing process,
  • stem cells are triggered in the scalp’s hair follicles and then they induce the hair growth process,
  • it increases blood supply to the scalp. That helps to distribute nutrients that your hair follicles require to have any substantial hair growth,
  • it assists the absorption of topical hair loss solutions.

What size of dermaroller should you use for hair loss?

dermaroller size for hair

The difference between all of the dermaroller products is based on the size of the needle. There are multiple sizes to choose from. Currently, you can choose from these sizes: 0.15 mm, 0.25 mm, 0.5 mm. 0.75 mm, 1.0 mm, 1.5 mm.

But guess what? There is a proven strategy that works just so well. And it’s something like this: you can use two dermarollers of various sizes to treat your hair loss.

What could be the reason for this?

See, a roller with smaller needles (0.15 – 0.25 mm) is the best for boosting the absorption of topical scalp treatment. And despite the fact that some patients worry about experiencing pain or bleeding, that does not occur with the latter sizes. It is completely safe to use in the comfort of your home. This can be applied at least once a week.

A dermaroller with longer needles (0.5 – 1.5 mm), on the other hand, significantly boosts the production of endothelial growth factors for hair. Such dermarollers for hair growth are the most effective. You just need to use it once 1-3 weeks.

Dermarollers with smaller needles have needles measuring 0.25 mm to 0.3 mm. It is okay to use the 0.25 mm roller everyday if your scalp is well tolerant of everyday treatment. Otherwise, treatment every other day is also effective.

  • 0.15 – 0.3 mm dermarolling – every 1-3 days.
  • 0.5 – 1.5 mm dermarolling – every 1-3 weeks.

Larger dermarollers with needles measuring 0.5mm to 1.5mm are the ideal instruments for boosting the production of endothelial growth factors.

I would advise using them once a month, but you can also use them once weekly if you can tolerate weekly treatment with these dermarollers.

Just a little advice here though:

The larger the size of the needles, the more painful the procedure. Case in effect, the 1.5 mm dermaroller is associated with a lot of pain and some bleeding. Which is why I recommend that you use it once a month.

But don’t worry that’s normal. If that makes you feel uncomfortable, it can be managed by applying slightly less pressure against the skin or using micro-needling numbing cream if the pain is getting unbearable.

Despite the pain, these sizes are undeniably beneficial because the longer needles are more effective as they can get deeper into the scalp and more effectively initiate the regeneration process. Anyways, another recommendation is that you should use these large needles under close supervision by a professional.

How to use a dermaroller

For this procedure, you need a micro-needling device, a dermaroller or a dermastamp. Micro-needling requires certain steps that you must take for it to be effective.

Be sure to clean the dermaroller before the use with alcohol or a disinfecting spray. Also, clean your scalp before beginning the treatment.

To start off, apply the micro-needling device directly onto your scalp and massage it evenly to ensure that you cover the scalp fully. But make sure to do that in sections.

Subsequently, use a dermastamp or a microneedle (depending on the length of your remaining hair. Remember to wet your hair if it’s long but you still want to use a dermaroller.

Start at the frontal region of your head just at the hairline as you advance and work your way towards the back of the head or the occipital region of the scalp. Do this one time up and down, then once going side to side, and then one time going across diagonally. You, then, have to repeat this process.

You should be careful to repeat this process back and forth until you have covered all the target areas of the scalp. Personally, I always recommend rolling or stamping each area between 10 and 15 times. This ensures that the scalp is covered adequately and that the hair restoration product is well absorbed.

Each time you use the dermaroller, always disinfect when finished and dry off the roller before putting it away. By following these strategies, the dermaroller technique will be almost complete. You only need to wrap it by applying the hair restoration product once again and massaging your scalp gently.

Potential side effects of using a dermaroller

The dermaroller is a safe product to use for hair loss, but there is a potential risk of complications that can occur. Apart from the pain that you can feel when you use larger dermarollers, the side effects are a combined contribution from other hair loss treatments such as topical products.

What does this even mean?

See, most topical treatments for hair loss are alcohol-based. Considering that scalp treatments with dermarollers rid the skin of its moisture, a combination of alcohol-based ingredients and reduced moisture is a prerequisite for skin irritation, dryness, and itchiness.

These side effects are not observed when the topical treatments for hair loss are not alcohol-based hence the reason why they are highly recommended.

Other potential side effects can occur based on the needling treatment you use. When you consider the procedure for using a dermaroller outlined above, the first and the last processes involve the application of topical hair treatments.

Now, if you use larger needles, you will have to go easy on the final step of applying topical treatment after rolling, especially when the topical product is minoxidil.

Let me make the warning clearer and easy to understand:

Never apply minoxidil immediately after a micro-needling treatment with needles measuring 0.5 mm to 1.5 mm.

Doing so may exacerbate unprecedented chemical burn because these longer needles increase the risk of getting the chemicals into your bloodstream.

If you use longer needles, you should wait for at least 24 hours before finishing the treatment procedure with a scalp massage using your favorite topical hair loss treatment product.

Nevertheless, an infection can occur because when you are using the dermaroller you are literally puncturing the scalp which causes irritation where germs can get to. This is why it is necessary to clean the dermaroller before and after each use as this is one of the common causes of infection.

It can become painful while you are treating your scalp and experience soreness afterward. What is more, it can lead to discomfort, ooze produced by wounds, and bruising of the scalp.

After treatment, you may experience swelling and redness of the treated area, and this can be experienced for a couple of days after treating the scalp.

Go-to micro-needling tips

The needle sizes recommended for the procedure are dependent on the amount of hair that is still remaining on the head. Dermaroller is also used when stimulating collagen production in the skin to curb the aging symptoms of the skin.

Conveniently, the needles used in dermaroller for hair loss are considerably shorter than the needles used for collagen treatments.

Sparse hair is common among men who have shaved even the remainder of their receding hair. In such instances, the best options are dermarollers measuring between 0.25mm to 1.0 mm.

I know you might be asking, how about the treatment for women who have lost their hair, though the remaining hair is still quite long? Well, a dermastamp is the preferable choice for such cases. Dermastamps prevent hair from getting caught up within the roller and pulled.

If women with long hair need to use a dermaroller, the hair should first be wet to make it stay flat. This reduces the likelihood that the roller will catch and pull the hair.

Ideally, using dermastamps takes a considerable amount of time, longer than when using a dermaroller. It is important to ensure that every area of the scalp is covered by the treatment.

To sum up this section, if you are treating your hair loss at home, you should be aware that hair loss treatment is an ongoing process and not a one-time event. This means that you should try getting regular with your treatments for you to achieve optimum results.

Be cautious when choosing the dermaroller. Very cheap dermarollers often have needles of asymmetric shape and made of low-quality materials.

Ideally, consult your dermatologist, before ordering a dermaroller. If that is not an option for you, do extensive research and opt for reputable brands, who have years of experience and uses premium materials for their products.

If you’re looking for an inexpensive option and want to purchase your dermaroller from a reliable supplier – you might want to check Lipogaine, who specializes in hair loss products and currently offers a 1.5 mm Max Roller System dermaroller for $25.


Quite a number of studies have highlighted the effectiveness of dermaroller in the treatment of hair loss. although there are factors that determine how effective your results will be, certain studies have also deduced the importance of dermaroller, not only for hair loss but also for the maintenance of skin integrity.
