I have been battling hair fall for quite some time now, but my dermatologist recently advised me to start using a dermaroller for better results. Initially, I was a bit skeptical about rolling tiny needles over my scalp, but after doing some research, I decided to give it a try. The process feels oddly therapeutic, and mixing it with essential oils has made my haircare routine more effective. It is too early for dramatic results, but I do hope to have healthier, fuller hair.A dermaroller is a handheld device that has tiny microneedles. This means it is minimally invasive and can be used to stimulate hair growth. How does it work, and what should you know before using a dermaroller in your hair care routine? Let's dive deeper into the science, usage, benefits, and precautions of using dermarollers for hair growth.Dermarolling, also known as microneedling, is a process of creating micro-injuries on the skin or scalp with fine needles. These tiny pricks spur collagen production, improve blood circulation, and enhance the absorption of hair growth products such as serums and medications.The process triggers the body's natural healing response, which helps rejuvenate hair follicles and creates an environment that is conducive to hair regrowth. Although it has been used most for skin treatments, its application on the scalp is turning out to be beneficial in the fight against hair loss.How Does Dermarolling Work?1. Enhanced Product AbsorptionThe micro-injuries created by the dermaroller allow haircare products, such as minoxidil or natural oils, to penetrate deeper into the scalp, maximizing their effectiveness. 2. Boosts Collagen ProductionCollagen is important for maintaining the health of hair follicles. By promoting its production, dermarolling strengthens hair roots and prevents thinning. 3. Improves Blood FlowIncreased blood circulation delivers essential nutrients to hair follicles, supporting robust hair growth.4. Stimulates Sleeping FolliclesWith microneedling, possibly sleeping follicles can be revived and new hairs may grow in previously thinning or balding locations.How to Use a Dermaroller for Hair RegrowthCorrect techniques and proper hygiene should always be followed during the use of a dermaroller to fully maximize its performance: Oil and debris around the scalp are removed by giving it a full scalp cleansing process. Sterilize with rubbing alcohol as much as possible to avoid an infection.Roll the dermaroller gently over the scalp in vertical, horizontal, and diagonal directions.Concentrate on areas that are thinning or losing hair. Be cautious not to press too hard on the skin in order not to irritate or cause injury.Use a serum or hair growth serum recommended by a dermatologist directly after microneedling treatment to allow for increased absorption into the skin.Re-sanitize the dermaroller and store it in a clean, dry container.Use the dermaroller once a week initially, and then gradually increase to twice a week as your scalp adjusts. Please consult a dermatologist for more personalized advice.Choosing the Right Dermaroller for You Choosing the right dermaroller is important to ensure safety and effectiveness: Needle Size: For scalp treatments, opt for needles ranging from 0.5 mm to 1.5 mm.Quality: Choose a device with medical-grade materials to ensure durability and safety. Ergonomics: Look for anti-slip handles and clear usage instructions for ease of use. Professional Guidance: Consider consulting a dermatologist before starting treatment to ensure compatibility with your scalp condition.Benefits of Using Essential Oils and Serums to UseWhen the dermaroller is used in conjunction with essential oils or serums, its effect becomes much stronger. The following are some of the most commonly used: Lavender Oil: Enhances hair growth and calms the scalp.Rosemary Oil: Enhances circulation and prevents early graying.Cedarwood Oil: Moisturizes and makes the scalp less flaky.Thyme Oil: Promotes volume and hair growth.Use only after diluting essential oils with a carrier oil like coconut or almond oil, so it doesn't cause irritation to the scalp.Are There Any Side Effects Or Dangers of Using Derma Roller?Dermarolling is essentially safe, however, it will cause some adverse effects in some cases. Temporary side effects: Redness SwellingPain or DiscomfortRisk of InfectionSun SensitivityDo not dermaroll if you suffer from scalp infection, eczema, or diseases such as diabetes. Pregnant women should never use derma rollers because this can pose a dangerous risk to her health.At-Home vs Professional Dermaroller TreatmentsWhile at-home treatments are cost-effective, professional dermarolling sessions provide access to trained expertise and advanced tools. Consider starting with a dermatologist-supervised session to learn the proper technique before transitioning to self-application. Hair regrowth is a gradual process. Most users notice visible improvements within 3 to 6 months of consistent dermarolling. Combined with a comprehensive haircare routine, this method can yield long-term benefits.Derma-rolling offers an attractive, accessible solution to any hair loss problem. This method stimulates collagen production, boosts the absorption of any product applied, and promotes blood flow. While it can revolutionize your hair regime, success is dependent on dedication, correct technique, and a regard for hygiene standards.Disclaimer: This article is for information purpose only, do not substitute this for professional advise.
