The dermaroller is causing a stir on social media with its promise to stimulate hair regrowth through its micro-needles. Is it merely a gadget or a genuine revolution for thinning hair? Let us tell you everything!
The scalp undergoes a continuous renewal process: while some hair strands grow, others die and fall out. Given that the average lifespan of hair ranges from two to seven years and that we have about 120,000 strands on our heads, it is entirely normal to lose several dozen each day (and sometimes more, depending on the season). However, when hair loss significantly exceeds this natural phenomenon, the risk of thinning becomes real, even without excessive use of styling tools. Various factors can contribute to accelerated hair loss, regardless of age, gender, or hair type: androgenetic alopecia (local hormonal disorder), iron deficiency, thyroid issues, medical treatments, pregnancy, and more.
Dietary supplements, scalp massages, anti-hair loss treatments, castor oil… There are effective solutions for caring for tired hair, but when they don’t work, remember there is a natural method to experiment with among current hair trends: the dermaroller.
What Is A Dermaroller?
Resembling a small torture device, the dermaroller is actually very beneficial. It features a handle that is easy to grip, with a rotating cylinder topped with hundreds of micro-needles, making it easily recognizable and unlike any other tool. With each needle measuring about one millimeter in diameter and varying in length from 0.5 mm to 1.5 mm depending on the chosen roller, the micro-needles are what give the dermaroller its effectiveness. To promote hair growth most effectively, we recommend choosing a length of 0.25 mm to 0.5 mm, which is best suited for this purpose.
While still relatively unknown, the dermaroller is gaining popularity due to its numerous benefits: it stimulates the epidermis through micro-perforations, essential for the revitalization process of the scalp. This tool allows you to easily and affordably practice microneedling at home. Using it promotes blood circulation, energizes hair follicles, stimulates stem cells as well as the dermal layer, and enhances the effectiveness of scalp treatments (by allowing them to penetrate deeper). In summary, the dermaroller not only reduces hair loss but also promotes regrowth, improves quality, and adds volume and density.
How To Use A Dermaroller?
Recommended for anyone experiencing either early hair loss or a significant decrease in hair growth, the dermaroller is very easy to use. You simply need to apply it to your scalp, being careful not to apply too much pressure. Roll it back and forth up and down, diagonally, and horizontally: move the roller in each direction five to ten times before switching directions. Continue these gentle movements over small targeted areas, for two to three minutes each, until all the thinning areas of your scalp have been treated. If your scalp tingles and feels warm, that’s a good sign: the dermaroller is doing its job and effectively stimulating your scalp. This at-home microneedling session will take only a few minutes, after which you can apply your chosen serum to maximize the benefits of its active ingredients. With this tool, your hair regrowth routine will become more comprehensive without requiring a lot of additional time.
Microneedling At Home: Precautions To Take
Be cautious about how often you use the dermaroller; we recommend not exceeding once a week. Since this technique creates micro-injuries on the scalp, the skin needs time to regenerate for optimal effectiveness without suffering damage.
Also, be sure to use your dermaroller correctly! It is imperative to use a disinfected tool (with a sanitizing spray, for example) on a clean scalp (which will limit the risk of infection). Lastly, the dermaroller should be strictly personal, and we advise against using it on open wounds, skin lesions, or irritated skin. You should also avoid using it if you have diabetes, blood issues, or are pregnant. Remember, this is an invasive technique that can have consequences if misused.
What Are The Results After Using The Dermaroller?
As mentioned, in addition to limiting hair loss and stimulating growth, the dermaroller appears to also have the ability to make hair denser and thicker. Whether used alone or in conjunction with other targeted techniques (dietary supplements, specific care, or others), this tool proves to be particularly interesting and promises quick results. In fact, after just a few months of weekly use, improvements can already be observed, even in individuals who are less responsive to other conventional therapies. However, in terms of results, do not compare yourself with other dermaroller users: each scalp is unique, and each growth cycle differs.
Finally, the use of the dermaroller is not limited to hair care. You can also use it to smooth the skin on your face, accelerate the healing of imperfections, and reduce cellulite and stretch marks on your body. A handy tool with multiple functionalities!
