Androgenic Alopecia Men and Female Pattern Hair loss. Microneedling as one of the most effective treatments.
Microneedling has gained widespread popularity as an effective treatment for reducing wrinkles, scars, stretch marks, and rejuvenating the skin. As an aesthetician with 20 years of experience, I've seen firsthand the remarkable results microneedling can achieve. However, when it comes to the scalp, this procedure is less commonly performed, yet it holds significant potential.
Scalp Microneedling
The scalp is a particularly sensitive area, with a complex network of capillaries that make it more prone to bleeding during treatment. This vulnerability makes it crucial to approach microneedling with extra caution. Before any needling treatment, especially on the scalp, a thorough examination by a trichology specialist is essential. Conditions like scarring alopecia or inflammation, which I encounter frequently in my treatment room, are absolute contraindications to microneedling. Instead of benefiting the patient, performing the procedure on such conditions could lead to further complications.
Therefore, it's imperative that any advanced scalp treatment like scalp microneedling is preceded by a proper and professional diagnosis, including a trichoscopy examination. This ensures that the treatment is safe and tailored to the specific needs of the patient, leading to the best possible outcomes.
Let's dive into the research that demonstrates the effectiveness of scalp microneedling (SMN) as a standalone treatment for androgenetic alopecia (AGA), a common form of hair loss. The study compares three different needle depths—0.5 mm, 1 mm, and 1.5 mm. Here's a simplified breakdown:
This study aimed to assess how well scalp microneedling works on its own to treat AGA and help regrowth hair by evaluating the results using three different needle depths. The goal was to determine which depth provided the best results in promoting hair regrowth.
Purpose of the Study:
- The researchers wanted to see how well scalp microneedling works on its own for treating AGA. They also compared how different needle depths affect hair regrowth.
Study Setup:
- 45 patients with AGA were divided into three groups, each receiving microneedling at different depths (0.5 mm, 1 mm, and 1.5 mm).
- The treatment was done using a device with small needles, and each patient had six sessions over three months.
- The results were evaluated by the patients themselves, dermatologists, and through detailed scalp imaging.
Results:
- Group A (0.5 mm depth): Showed the best results with moderate improvement in hair growth. Patients in this group had the highest increase in hair count and thickness.
- Group B (1 mm depth): Also showed moderate improvement, but not as much as Group A.
- Group C (1.5 mm depth): Showed poor improvement with little change in hair count or thickness.
Key Findings:
- The 0.5 mm depth was the most effective for hair regrowth in this study.
- Deeper needle depths (1 mm and 1.5 mm) were less effective and might even cause more trauma to the scalp without additional benefits.
- The 0.5 mm depth also caused the least amount of pain during the procedure.
Microneedling at a 0.5 mm depth is the most effective treatment for hair loss due to androgenetic alopecia (AGA). The evidence speaks for itself. However, it is crucial that this procedure is performed by a qualified specialist who is properly trained in such treatments. Deeper doesn't mean better. There are significant risks involved that clients need to be aware of:
-
Incorrect Procedure: Not every scalp and hair issue should be treated with microneedling. If the wrong procedure is applied, it can lead to further complications rather than improvement.
-
Lack of Proper Examination: Failing to thoroughly examine the scalp before treatment can result in scarring and fibrosis. Scalp scars can cause permanent baldness because damaged hair follicles cannot regenerate, worsening the condition instead of improving it.
-
Contraindications: Pregnancy, breastfeeding, uncontrolled dandruff, seborrheic dermatitis, or even an unclean scalp are all contraindications for this treatment. The scalp must be clean, exfoliated, and prepared before undergoing microneedling.
While this treatment can be uncomfortable, and even painful, when performed correctly by an experienced professional, it can yield significant results. My crucial advice is to steer clear of unqualified specialists who lack proper knowledge of physiology, anatomy, trichological diagnosis, and scalp treatments, as well as hands-on experience. Trusting someone without these qualifications can lead to serious consequences, and you could end up losing more than you gain.
