Derma Roller for Hair Regrowth – An unconventional hair loss treatment

We already know that hair loss can be really stressful, and have negative effects on a person’s self-esteem and confidence. It might even cause depression in some cases.

Fortunately though, there are a few treatment options available today to both stop hair loss, and regrow lost hair. One of those treatments, which I found out just recently, is a device called a derma roller.

In this post I’ll talk about derma roller for hair regrowth, and why I think it might be a great treatment worth trying.

What is a derma roller and how does it work?

A derma roller is a hand held device with a cylinder roller that is covered with small needles. The device is rolled over the scalp, and while doing so the tiny needles penetrate the skin’s surface and cause minor skin injuries which supposedly regenerate the health of hair follicles and promote new hair growth.

How does it do that? It is believed that these skin injuries trigger a wound healing response, which stimulates the production of a protein that leads to hair growth and inhibits a protein that causes hair loss.


This method is also called Microneedling, and although it sounds unorthodox at first, it is actually widely used as a facial anti aging skin treatment.

Derma rollers also increase blood flow to the hair follicles, which helps hair follicles receive more essential nutrients that help hair grow fuller and longer.

The different sizes of derma rollers, and which should you use?

Derma rollers come with different needle lengths. The most common needle lengths are: 0.15mm, 0.25mm, 0.5mm, 0.75mm, 1mm, and 1.5mm. These sizes serve for different purposes and have a few important differences.

The small sizes 0.15mm – 0.5mm only penetrate the epidermis layer of the skin (the top layer) and are intended to boost the absorption of topical hair loss treatments such as minoxidil, rather than regenerate hair follicles by themselves. These sizes can be used everyday or every other day.

Studies show that a derma roller can improve the absorption of minoxidil by up to 10 times! But for that to happen, minoxidil needs to be applied right after using the 0.15mm-0.25mm derma roller, before the micro injuries heal and close the entrance to the epidermis layer.

0.5mm – 1.5mm lengths penetrate deeper levels of the skin, and are NOT intended to be used with topical treatments such as minoxidil, because minoxidil should not penetrate the deep levels of the skin, as this might cause severe side effects. In fact if you want to use minoxidil or other topical products, you must wait at least 24 hours after a derma roller session.

Needles in this length range are the most effective for improving the health of hair follicles and hair growth, but how often they can be used is different.

A 0.5mm derma roller can be used 2-3 times a week with or without minoxidil. A 1mm derma roller should be used once a week or once in 2 weeks, and a 1.5mm derma roller should not be used more than once a month.

I recommend trying the small size 0.15mm-0.25mm with minoxidil every other day, and the 0.5mm size once to twice per week (without minoxidil).

How to use a Derma Roller?

Before and after using the derma roller, disinfect the device with alcohol. Also don’t forget to clean your scalp, so it’s a good idea to shower before a session.

Be sure to only apply a moderate pressure, since applying too much pressure won’t yield better results and it can cause injury or skin irritation .

Start by slowly moving the derma roller up from the front of the scalp to the back of the head. Repeat this until you have covered all areas of your scalp.

Then, do the same but this time move from right to left or left to right, and repeat until you have covered all the area of the scalp.

Finally, repeat this process diagonally.

Is the derma roller really effective in battling hair loss?

Research has shown that derma roller is effective in repairing hair loss, especially when used in combination with minoxidil. In fact, Men taking minoxidil with a derma roller experienced much more hair regrowth than men who only used minoxidil.

Of course like any treatment its effectiveness varies from person to person, but generally reviews on this product have been great.

Some benefits of derma roller include:

  • Increased blood flow to the scalp and hair follicles
  • Better absorption of minoxidil (when using derma rollers less than 0.5mm long)
  • Initiation of the body’s wound healing response which stimulates hair growth and stops hair loss


The derma roller seems like a promising treatment for hair loss. Although not many studies have been made, those who have shown promising results after 3-6 months of treatment.

Considering its cheap price, I would really recommend you try this out, especially if you have been using other treatments and not getting satisfactory results.

I have personally ordered this product (0.5mm size) and can’t wait to start using it. If you are interested, get your derma roller here.

  1. Very informative. It seems that Hair loss doesn’t care whether you’re a man or a woman.
    Good to know that there is a Derma Roller that could help.

    Would this Derma Roller help grow your hair back? I could suggest it to someone.

  2. Very interested article. Id like to see some before and after photos the derma roller. Im bald myself and will be learning more about seeing how this work.

  3. Thank you for a very interesting and informative article about the derma roller for hair growth.

    My question is how effective is it for a person who has been bald for some time rather than someone who is thinning and just starting to lose their hair?

    1. Hi, well if a person is completely bald then it probably wouldn’t help much. But if a person has thinning hair and losing more and more hair, it will most likely improve his condition.
      I hope that answers your question.
      Have a great day.
