Using a derma roller is easy as it just involves rolling it on your head in different directions but the real trick is the pre and post care. To use a derma roller effectively, it is important to choose the right needle size, prepare your skin & scalp for the process and sterilize the roller. You also have to ensure that the post-treatment care is done properly. We are here to tell you all! 

This blog will explore derma roller and how to use it in detail along with its effectiveness, offering insights, tips and step-by-step guide on how to use derma roller for hair. 

What is a Derma Roller? 

Derma rolling, also known as micro needling or collagen induction therapy, is a cosmetic procedure that involves the use of a device called derma roller. This device has a cylindrical shape with tiny needles that usually vary in length from 0.2 mm to 1.5 mm. The derma roller is a manual tool equipped with numerous small needles that are rolled over the skin, generating numerous tiny pinpricks, referred to as micropores, on the skin's surface. These needles are crafted from surgical stainless steel or medical-grade titanium. While derma rolling is commonly used for skin rejuvenation, it has also gained attention as a potential method for promoting hair growth.  

What is a Derma Roller Used for? 

Derma rollers are versatile tools suitable for use on the skin, beard, and scalp. The primary goal is to promote collagen production, enhance circulation, and encourage cellular turnover, leading to various benefits for both skin and hair. Individuals facing hair loss often explore derma roller for hair growth as an effective option. Similar to micro needling procedures performed by dermatologists, at-home derma rolling induces small tears in the skin or scalp. This action serves as a signal to the brain to initiate the healing process, resulting in increased blood flow and collagen production in the targeted area.  

How to Use Derma Roller for Hair Growth

If you’re considering derma roller for hair growth, you have two options: professional clinic treatments by a licensed dermatologist or at-home sessions. While professional clinic visits may yield better results, the cost can be prohibitive over time, making at-home micro needling an attractive alternative.

A recommended approach is to start with a few professional treatments to gain experience. After that, armed with insights, you can confidently transition to at-home micro needling.

How does derma roller work for hair growth? 

When the derma roller is gently rolled over the scalp, the fine needles create micro-injuries in the skin. These micro-injuries stimulate the body’s natural wound healing response, triggering the production of collagen and growth factors. 

The increased collagen production helps to strengthen and improve the elasticity of the skin on the scalp, creating a healthier environment for hair follicles. Additionally, the micro needling process enhances blood circulation to the scalp, promoting better nutrient and oxygen delivery to the hair follicles. This improved blood flow is crucial for the optimal functioning of hair follicles and the promotion of hair growth. 

Furthermore, the micro-channels created by the derma roller facilitate the better absorption of topical hair growth predicts, such as minoxidil or other serums, into the scalp. The combined effect of micro needling and enhanced product adsorption makes derma rollers a popular tool for those seeking to address hair loss and stimulate natural hair regrowth. Regular and careful use of derma roller may contribute to thicker, healthier hair over time. 

Who can use a derma roller for hair growth?

Derma rollers for hair are suitable for those seeking an at-home hair loss solution, serving as an initial step for regrowth or in combination with topical products like hair loss serums. While generally applicable, individuals with skin conditions such as psoriasis or eczema or a history of blood clots should consult a doctor or dermatologist before use. It’s essential to avoid derma rolling on an area with active cane or warts to prevent potential spread across the skin. 

How to Choose a Derma Roller?

There are several factors to consider when choosing the right derma roller for you. Factors such as needle size, handle design, needle material and much more must be considered to ensure safety and effectiveness of derma roller for an individual. 

Needle Size

Derma rollers come with varying needle size, typically ranging from 0.25 mm to 1.5 mm. For hair growth, 540 short microneedles at 0.5 mm are commonly recommended. The appropriate needle size may vary based on your specific goals, ensuring effective scalp stimulation without causing undue discomfort. 

Handle Design

Always consider the design and material of the derma roller handle. Choose a handle made from sturdy materials for durability. Opt for a design that offers a comfortable grip to enhance control during the rolling process and reduce the risk for accidents during use. 

Needle Material 

Common needle materials used for derma rollers are stainless steel and titanium. Choose a derma roller with needles made of titanium or medical-grade stainless steel. Titanium is preferred for durability, while stainless steel endures effectiveness and safety. 

Reputable Brand

Select a derma roller from a reputable brand to ensure quality and safety. Research thoroughly through customer reviews, product specification, and the brand’s reputation in the market. Seek professional help if you can’t decide which derma roller brand to choose. 

Specific Goals

Tailor your derma roller choice to your specific hair growth objectives. Understanding which derma roller would be best for your scalp and helps in hair growth is very important. Different needle sizes and materials may be more suitable for certain goals. 

While choosing derma roller for yourself, prioritize safely, user comfort, and effectiveness in making your decision. Always consult with professionals if unsure about the most suitable derma roller for your needs.  

At-Home vs. Professional Derma Roller Treatments 

Understanding derma roller for hair and its types 

As the derma roller for hair growth is gaining popularity, numerous advanced technologies and options are emerging in the market. Understanding the fundamentals of each derma roller and its various types allows individuals to choose the most suitable option for their specific skin care or hair care goals.

1. Derma roller 

The original micro needling tool, the derma roller, is a handheld device shaped like a drum with 192 stainless steel or titanium needles. It is manually rolled over the skin in various directions. Derma rollers for hair come in different sizes: 

• Regular size having 192 to 540 needles for the face or scalp
• Body rollers, three times wider with 1000 to 1700 needles, are ideal for larger areas
• Mini rollers, with 192 to 250 needles, target small and sensitive areas.

Needles lengths on derma rollers range from 0.1mm to 3mm, addressing various skin concerns. Due to the rolling motion, the needles penetrate at an angle, potentially causing micro-tearing and increased recovery time. Derma rollers can typically be used 10-15 times before disposal, but advanced models offer interchangeable heads for cost-effective replacement.

2. Derma pen

The derma pen, also known as a micro pen or micro needling pen, represents an upgraded version of the derma roller. It is a smaller, pen-like device with replaceable single-use needle cartridges containing 9 to 36 small needles, often mistaken for a misbranded as a derma stamp.

Unlike derma roller and derma stamp, which are not motorized and can be disinfected, the needle cartridge of the derma pen needs to be disposed of after each treatment, lasting up to 15 treatments. The key distinction between derma pen and derma roller lies in the derma pen being a fully automated, electrically powered, and rechargeable micro needling device.

Functionally, the derma pen operates with a stamp-like motion over the treated area, held perpendicular to the skin and switched on for the penetration motion, contrasting with the manual rolling action of derma roller.

3. Derma stamp

The derma stamp is a blend of derma roller and derma pen, resembling a stamp tool in design. Unlike the cylindrical derma roller, the dermas tamp features a round, square, or rectangular-shaped flat tip covered in tiny needles attached to a handle. Due to its flat surface, the derma stamp is pressed vertically (stamped)  into the skin, creating precise and even treatment without the angled puncture wounds associated with derma rollers.

Derma roller VS Derma pen VS Derma stamp: Understanding the differences

Derma roller for hair growth mechanism explained

Initially employed by dermatologists for scar healing and skin rejuvenation, derma rolling involves creating punctures and micro-incisions to harness their skin-enhancing benefits. Studies suggest its potential in preventing hair loss and promoting hair growth. Enhancing blood circulation in the scalp and stimulating cell regeneration creates a healthier environment for optimal hair growth. Let's delve into understanding the mechanism of the derma roller for hair growth: 

1. Accelerated Product Absorption 

The derma roller facilitates the swift absorption of hair products into the scalp by penetrating the skin’s dermal layer. Users commonly apply various treatments for hair loss, such as topical steroids, platelet-rich plasma, and minoxidil during micro-needling sessions. 

2. Scalp Massage and Increased Blood Flow

Scientific studies indicate that derma rollers enhance blood circulation in the scalp, promoting hair growth and thickening. Micro-needling triggers  the natural regeneration of collagen and elastin in the body, fostering not  only hair growth but also clearer and more radiant skin.

3. Enhanced Oxygen Supply to the Roots

Derma roller for hair encourages blood flow around the roots, ensuring a more robust environment for hair growth.

4. Hair Thickening and Prevention of Excessive Shedding

Micro-needling prompts hair germination during the anagen phase of hair growth, resulting in new hair that is stronger and thicker due to the increased collagen around the hair follicles. This helps prevent excessive hair fall. 

5. Prolonged Hair Regression Prevention

In the catagen phase, where hair follicles shrink and growth diminishes, micro-needling aids in preventing hair shedding, contributing to the prolongation of the hair regression phase.

Essential Oils and Serums for Enhanced Results

Essential oils, extracted from plants through distillation, are not just pleasing atoms but powerful treatment for your scalp. These oils, rich in beneficial compounds, are lightweight and easy to use. After derma rolling, essential oils and serums can nourish the scalp, improve hair health, and one can achieve stronger and thicker hair with minimal side effects. There are some oils and serums that address specific scalp issues. Consulting with professional doctors on which oil and serum to use is important. 

Best Essential Oils to use with your derma roller for hair

1. Lavender Oil 

Lavender essential oil, extracted from lavender flowers, stimulates hair growth due to its antibacterial and antifungal properties. Studies show it can speed up hair growth when applied topically. Combining lavender oil with derma rolling is a simple and effective way to encourage faster hair growth and address hair loss concerns. 

Application method: For a gentle application, mix lavender essential oil with carrier oils like olive or melted coconut oil, using a ratio of 1 part of lavender oil to 6 parts carrier oil. After derma rolling, massage the blend onto your scalp, let it sit for 10-15 minutes, and then wash it off with mild shampoo. 

2. Rosemary Oil 

Rosemary oil is an ideal companion for derma rollers for various reasons. Its lightweight texture ensures a non-oil feel, leaving air fresh post-application. It regulates sebum production, preventing excess greasiness and flatness. Rich in antioxidants, rosemary oil delays premature greying and enhances scalp circulation for faster hair regrowth. Additionally, it addressed scalp acne, offering soothing and antifungal properties to alleviate itchiness and maintain a clean, healthy scalp. 

Application method: For rosemary essential oil, almond and pumpkin seed oils are excellent career options. Combine a few drops of rosemary oil with 3 tablespoons of any carrier oil, apply after derma rolling, and leave it on for 4-6 hours. Wash it off using a mild shampoo. Consistently follow this routine for a minimum of 6 months to observe noticeable changes in hair growth. 

3. Thyme Oil 

Thyme oil, rich in thymol, is a potent addition to your derma rolling routine. Packed with nutrients and antioxidants, it promotes new hair growth and boosts volume. Thyme oils' anti-inflammatory and antimicrobial properties maintain a healthy scalp, fostering the formation of new hair strands.

Application method: For application, mix 1-2 drops of thyme oil with a carrier oil, gently massage onto the scalp, and leave for 10-15 minutes. Follow with a mild shampoo and conditioner. Limit thyme oil treatment to once every 3-4 weeks to prevent scalp sensitization and irritation.

4. Cedarwood Oil

For a healthy scalp, cedarwood essential oil is a great ally when combined with derma rolling. This emollient oil boosts circulation, fights dryness and flakiness, and regulates sebum to prevent excessive greasiness. Cedarwood oil, like other oils on this list, has antifungal and antibacterial properties to manage scalp infections. Regular use results in well-hydrated, shiny, and bouncy hair, free from brittleness.

Application method: To use, mix 2-3 drops of cedarwood oil with 1 tablespoon of raw, organic coconut oil, apply to the scalp, let it sit for 30 minutes, and then wash it off with a gentle shampoo and conditioner for optimal results.

What are the Derma Roller for hair side effects?

While the derma roller is an effective tool for hair growth there are few side effects too which one should understand before using derma rollers. 

1. Immediate Reaction

Micro-needling with derma rollers may lead to immediate reactions like bruising, oozing, redness, swelling, pain and the potential for scarring. These effects can impact overall comfort during the recovery periods. 

2. Post-Procedure Effects and Recovery

The treated area may experience redness and inflammation for a few days post-procedure. While these effects are expected to fade within 5 days, understanding the temporary nature of these reactions is crucial for managing expectations and ensuring a smoothie recovery process. 

3. Potential Risks 

Individuals with a history of acne, eczema, conditions hindering healing (like diabetes), or those on specific medications may not be eligible candidates for derma rolling. 

4. Pregnancy Caution

Pregnant individuals should avoid micro-needling due to potential risk to both mother and child. Understanding the potential risks and erring on the side of caution is vital for maternal and fetal health.
