Side Effects of Derma Roller for Hair Growth

Side effects of derma roller for hair

Derma rollers are becoming a standard product for promoting hair growth in the ever-changing cosmetic industry. The world market for derma rollers was estimated at $297.4 million in 2020 and is expected to grow at a compound annual growth rate of 6.7% from 2021 to 2030.

As companies incorporate derma rollers and microneedling procedures into their offerings, it’s crucial to recognize that while these treatments offer promising results, understanding the potential risks is paramount.

Now, let’s comprehensively explore the side effects of derma rollers and equip you with practical tools to mitigate risks and enhance patient satisfaction.

Comprehending Microneedling

Derma rollers penetrate the scalp with minute holes made by tiny needles embedded in them. This regulated injury triggers the body’s natural healing reaction, which increases collagen synthesis and blood flow.

Collagen supports a healthy scalp environment and increases blood flow to hair follicles, possibly producing more robust hair growth.


How do Derma Rollers Work?

To promote hair development, derma rollers use a technique known as microneedling, which essentially involves creating controlled injuries. This is an explanation of the underlying science:

  • Microscopic Punctures: As you roll a derma roller over a particular scalp area, the minuscule needles cause small punctures.
  • Initiating the Healing Process: These punctures are minor, controlled wounds that don’t harm. Nevertheless, they deceive the body into believing that healing is necessary.
  • Blood Flow Boost: As part of the healing response, the scalp experiences increased blood flow, which provides hair follicles with vital nutrients and oxygen.
  • Collagen Production: Increased collagen production is another aspect of the healing process. The protein collagen gives the skin, including the scalp, shape and support.
  • Improved Conditions for Hair Follicles: Hair follicles can perform more optimally in a healthy environment thanks to increased blood flow and collagen production. This may result in denser hair growth, produced by more robust and healthier hair follicles. Enhanced Hair Growth: A stimulated scalp environment may encourage new hair growth besides addressing hair loss.

What is the ideal frequency for using a derma roller on the scalp?

There are a variety of solutions for scalp derma roller frequency. Optimizing outcomes and reducing hazards is akin to taking a “go low and slow” strategy. The summary is as follows:

  • Start Mildly: The starting frequency should be one week or every other week. This reduces the possibility of irritation and gives the scalp time to acclimate to the microneedling procedure.
  • Listen to the Scalp: Observe the responses it receives. Reduce the frequency or take a break if they suffer any redness, swelling, or pain that lasts more than a day or two.
  • Length of Needle Matters: The derma roller’s needles also have an impact. More often (every other day) and more gently can be achieved with shorter needles (around 0.25mm). Since they produce deeper punctures, longer needles (1.0 mm or greater) are usually advised to be used less frequently (every two weeks).
  • Concentrate on Consistency: For the best outcomes, consistency is essential. Even if patients only use it once a week, maintaining a regular regimen is more beneficial than using it occasionally.

The Allure of Derma Rolling

Derma rolling’s potential effectiveness and ease of use make it appealing. In contrast to invasive procedures like hair transplants, it is a noninvasive technique that can be done in the comfort of one’s home.

Derma rolling is also reasonably priced compared to other hair restoration techniques, opening it up to a broader range of users. It provides thicker hair, more hair density, and better scalp health.

It’s crucial to remember, though, because microneedling compromises the skin’s ability to act as a barrier, leaving it more vulnerable to infection and discomfort.

7 Side Effects of Derma Roller

So, what are these side effects? The possible adverse effects are broken down as follows:

1. Skin irritation and redness

Minor skin irritation and redness are common aftereffects of derma rolling. The micro-injuries from the needles create this reaction, which usually goes away in a few hours to a few days. On the other hand, prolonged redness or increased sensitivity may be experienced by people with sensitive skin.

2. Pain and Discomfort

Depending on the needle length used and the individual’s pain threshold, rolling needles over the scalp can cause anything from minor discomfort to moderate agony. Excessive pain during or after the treatment may be a sign that the needles are too long or that too much pressure is being applied; however, some discomfort is to be expected.

3. Risk of Infection

There is always a chance of infection when the skin is punctured. Although derma rollers are usually used to clean skin, the risk of infection might be increased by improperly sterilizing the equipment or not practicing good hygiene. Increased redness, swelling, soreness, and pus or discharge are all signs of infection.

4. Skin Sensitivity

Some people may have more sensitive skin after derma rolling, especially in the days after the treatment. This sensitivity could manifest as a higher risk of sunburn or irritation from skincare products.

5. Bruising and Petechiae

Derma rolling may, in rare instances, cause bruising or the development of petechiae, which are tiny red or purple dots. Although these marks usually go away in a few days, some people may find them ugly or worry about them.

6. Exacerbation of Pre-existing Scalp Disorders

Derma rolling may worsen symptoms for people with scalp disorders like psoriasis or eczema. The tiny punctures the needles make can exacerbate underlying skin disorders and create inflammation.

7. Hair Shedding

Although derma rolling stimulates hair growth, some people may experience brief hair loss in the weeks following treatment. This regular shedding occurs when new hair follicles enter the growth phase, a typical element of the hair growth cycle.

Long-term side effects of using derma rollers for hair growth

Consumers and businesses have expressed interest and concern about the long-term impacts of derma roller use in the context of hair growth therapies.

Even though derma rolling seems a non-invasive way to encourage hair growth, it’s crucial to consider any possible long-term side effects resulting from regular or extended use.

Here are some things to think about:

Scalp Sensitivity and Irritation

Over time, prolonged or frequent derma rolling treatments may increase scalp sensitivity and irritation. The repetitive damage from the needles may compromise the skin barrier function, leaving the scalp more vulnerable to irritation from outside sources such as environmental toxins or hair products.

Skin Thinning and Damage

If longer needles are utilized or the operation is carried out too firmly, excessive derma rolling may result in skin thinning and damage. Over time, skin thinning may make one more susceptible to UV damage and early aging.

Hyperpigmentation and Discoloration

Following derma rolling, some people may have hyperpigmentation or discoloration of the skin, particularly if they have darker skin tones. Inconsistent pigmentation might develop over time due to persistent inflammation or poor micro-injury repair.

Risk of Infection and Scarring

Although these long-term consequences are more frequently linked to immediate post-treatment issues, repeated derma-rolling treatments increase the cumulative risk of these side effects.

Failure to follow suitable hygiene measures or improperly sterilize the derma roller can increase the risk of infection, which, if untreated, may leave scars.

Alterations in Hair Texture or Density

Although stimulating hair growth is the main objective of derma rolling, some people may experience changes in hair texture or density over time. This may be due to a person’s reaction to treatment, changes in hormones, or underlying scalp issues that may affect a person’s hair growth pattern.

Dependency on Treatment

People who use derma rolling extensively as their primary hair growth remedy may grow psychologically dependent on it. This dependence may emerge from the idea that using the derma roller continuously is required to maintain hair growth, which could cause worry or discontent if results eventually plateau or decline.

Reducing Hazards and Optimizing Gains

Because of its supposed benefits, derma rolling is still a popular choice for hair growth despite possible adverse effects. Take into account these pointers to enhance the benefits of derma rolling while reducing the risks:

Select the Appropriate Needle Length

The derma roller’s needle length significantly impacts its efficacy and possible adverse effects. Needles of 0.25 to 1.5 mm diameter are usually advised for hair growth. Longer needles carry a higher risk of discomfort, bleeding, and infection because they may pierce too deeply.

Maintain Good Hygiene

To lower the infection risk, ensure the derma rolling instrument is thoroughly cleansed and sanitized before and after each session. Furthermore, use a mild, non-comedogenic cleanser on the scalp to eliminate any debris, oil, or filth that might be pushed farther into the skin throughout the process.

Maintain a Regular Schedule

When it comes to derma rolling for hair development, consistency is essential. For best results, set up a consistent treatment schedule that is adhered to, usually once or twice a week. But be careful—too much derma rolling might harm the skin and slow the healing process.

Use Topical Treatments Carefully

Although derma rolling can improve topical product absorption, it’s crucial to select formulas that are both safe and appropriate for usage in conjunction with microneedling. Steer clear of products with harsh or irritating components, and always try new products on a section of your scalp before using them on your entire body.

Keep an Eye Out for Adverse Effects

Observe closely how derma rolling affects your skin, and watch for any strange reactions or indications of infection. If you continue to feel discomfort, swelling, redness, or infection symptoms, stop using the product and see a doctor.
