There are many options for hair regrowth. Laser treatment, home remedies, medications, and much more. But one of the safest and most effective solutions for hair loss is “micro-needling”. Derma rollers are used for the exact purpose. They might sound gory to you at first, but dermatologists also vote for this and support the usage of derma rollers for hair regrowth. 

What is a derma roller? 

Derma roller is an effective and natural way to enhance the regrowth of hair. Derma roller is the form of micro-needling and it consists of tiny needles varying from 0.25mm to 1.5mm. when you roll derma roller on your hair, its needles puncture holes in your scalp to make healing oils work better and reach easily to the hair follicles to work their magic. 

Micro needling is another word for derma rolling. But it isn’t as terrible as it sounds. Those tiny needles may though make small holes but they aren’t big enough to cause any injury. They are just meant to refresh and spark the natural process of hair growth by flooding your scalp with collagen (a protein that’s important for hair, bones, muscles, and other body parts’ strength and growth) and better blood flow, and better blood circulation helps with hair growth. 

Do derma rollers work for hair loss? 

Derma rollers are usually used as a treatment for antiaging skin or scars. It works by making your skin look fuller and raiser. It has also been working effectively as a cosmetic product, used for hair regrowth. But the question is; do derma rollers help with hair loss? Let’s take a look and get to this in detail: 

Derma roller is a plastic tool that works by pricking your scalp with tiny needles. The titanium needles just cut through the derma layer of skin deep enough to boost the blood circulation and create the production of new cells for improving hair growth. 

Yes, derma rollers do work with hair loss. You just need to understand, how? Derma roller is a very simple hair loss treatment, that can be done easily in the comfort of your home. Although, if you are afraid, you can have a medical professional do it for you. Derma rollers work by inducing collagen that could cure hair loss and help with better hair growth. 

Derma rolling is applied to the scalp to encourage the growth of stem cells in hair follicles in the treatment of male pattern baldness or other forms of alopecia (a.k.a. dermal papilla). When those stem cells mature into full-grown hairs, they’ll help you re-grow part of the hair that you’ve lost. 

Why isn’t derma roller a safe option for you to try at home? 

Derma rollers are cosmetic equipment that was initially used for acne scars. Drum-shaped rollers at the end of the handle consist of almost 200 microneedles. Micro needling requires a professional to do with derma rollers. Even if they can be purchased online for home use but they should not be used without assistance. Derma rollers help with hair growth and enhance blood circulation in the scalp, creating new cells that prevent and lessen hair fall. But you shouldn’t use it casually if you have no experience or have a sensitive scalp.  

Micro needling with derma rollers is relatively safe, but it might have minor side effects like: 

  • Bruising 
  • Pain 
  • Redness 
  • Oozing from scars 
  • Swelling 

If you are using minoxidil then it can worsen the effect of micro needling like itching and irritation on the scalp. But it’s rare, the most potential side effect that anyone could face is the risk of our wounds getting infected. If you don’t want an infection or a scar, then keep your scalp clean for a whole week to avoid a chemical encounter. Sunblock will help your scalp stay safe from UV rays. 

How does micro needling perform with dermarollers? 

Your healthcare professional will use a roller with needles on it to do microneedling. 

Needles can be as short as 1 micron or as long as a few millimeters in length. In a handheld gadget, they’re all at your fingertips. The instrument, which is also known as a roller, is rolled over the treatment region, causing small wounds. 

If microneedling causes a minor injury, it could trigger a release of hair-promoting hormones or perhaps directly stimulate hair growth. 

Rolling the derma roller across the skin while applying strong pressure is the method used for micro needling. 

In the case of micro needling for hair loss, this repeated, multidirectional rolling causes small bleeding pinpoints on the scalp. 

To induce the production of growth factors in hair follicles, micro needling is used to stimulate the dermal papilla, or stem cells. 

By inflicting small lesions on the hair follicles, the body’s natural defenses will stimulate the healing process and eventually new hair development, which will help reverse hair loss. 

A topical anesthetic will be applied to your scalp 45 minutes before the procedure. This aids in the alleviation of discomfort. 

While the actual procedure duration may vary depending on the size of the treatment region, the average time is less than 10 minutes. Depending on the purpose of the micro needling session, your healthcare professional may apply a topical balm or administer an injection to the treated area after the procedure is complete.

How to do derma rolling at home? 

It’s okay if you don’t want to spend money and feel like wasting your time on a 10 minutes’ procedure. But there must be some reason why professionals get paid for it and why it costs a lot.  

Micro needling might look simple and easy to do at home but there are many reasons why you should not try it at home. If you are untrained, unprofessional, and unfamiliar with the use of derma roller then you should never try it at home. You could do a lot worse than good to your scalp. Here are a few reasons why you shouldn’t use derma rollers at home: 

  • At-home dermarollers usually have shorter needles that don’t penetrate deep enough and aren’t effective for hair loss.  
  • Doctors have medicated and doctor-grade dermarollers with longer needles and microneedling pens that could penetrate deeper for better results. 
  • You cannot see your scalp, so even if you got the right dermaroller, you still don’t know how to use it, how much pressure to put on, or when to stop.  
  • Dr. Madan says that “I don’t recommend using at-home dermarollers because their needles are too short to give noticeable results and re-using dermarollers could cause infection and scars you would regret later. 

Do dermatologists support micro needling with derma rollers? 

The short answer is “yes”. Derma rollers have the full support of dermatologists and professionals. But once again, if you want the best results without any side effects, you need to get to a practitioner for it. 

According to some studies, derma rollers have been tested for pattern hair loss like alopecia. According to a 12-week study in 2013, a test was done on 100 volunteers from Mumbai for the first time to see the growth results in humans. Before that, micro needling was experimented on mice. Half of them were tested under minoxidil and the other half went under micro needling treatment. 

In both of these studies, participants and experimenters saw better results and growth rates on participants that underwent micro needling treatment.  

The point here is that micro needling with derma rollers is proven to be safe other than some minor side effects. And it has the full support of dermatologists as well.
