Learn how to safely and effectively use the GRO+ Advanced Dermaroller to stimulate thicker hair growth. Step-by-step scalp microneedling routine, pre-treatment prep, and post-care tips for best results.
If you have been exploring ways to boost hair thickness and density, microneedling with a dermaroller is one of the most effective at-home methods. The GRO+ Advanced Dermaroller from VEGAMOUR is designed to create micro-channels in the scalp, which stimulate natural collagen production and enhance the absorption of nourishing ingredients. When used correctly, this tool can help you achieve visibly thicker, fuller hair over time.

In this guide, we will walk you through everything you need to know about using the GRO+ Advanced Dermaroller — from why microneedling works, to proper preparation, a detailed step-by-step routine, and post-care recommendations. By the end, you will have a clear, safe protocol to incorporate into your weekly hair wellness regimen.
Why Microneedling Works for Hair Growth
Microneedling, also called collagen induction therapy, uses tiny needles to create controlled micro-injuries in the scalp. This process triggers the body’s natural healing response, which increases blood circulation and stimulates fibroblasts to produce collagen and elastin. For the scalp, this means stronger hair follicles and improved delivery of oxygen and nutrients to the hair roots.
The GRO+ Advanced Dermaroller is engineered with medical-grade stainless steel needles in a precise length to safely penetrate the scalp without causing damage. When you roll it gently over the skin, the micro-channels it creates also allow topical products to absorb more deeply — up to 25 times more effectively than surface application. That is why pairing the dermaroller with a compatible serum or treatment can dramatically amplify your results.
- Increases blood flow to hair follicles for better nutrient delivery
- Stimulates collagen production, which supports follicle structure
- Enhances absorption of scalp treatments and serums
Prepping Your Scalp for Microneedling
Proper preparation is essential to ensure a safe and effective microneedling session. Start by washing your hair with a gentle, sulfate-free shampoo to remove dirt, oil, and product buildup. For an even deeper clean, use the Scalp Clarifying Treatment before your session. This treatment helps remove excess sebum and dead skin cells, leaving the scalp fresh and primed for the dermaroller.

After washing, towel-dry your hair so it is damp but not dripping. Avoid applying any heavy conditioners or styling products, as these can clog the micro-channels. Sanitize your GRO+ Advanced Dermaroller by soaking the needle head in 70% isopropyl alcohol for at least five minutes. This step is crucial to prevent infection. Allow it to air dry on a clean towel before use.
- Wash with a gentle, sulfate-free shampoo
- Use Scalp Clarifying Treatment to remove buildup (optional but recommended)
- Sanitize the dermaroller with 70% isopropyl alcohol for 5 minutes
Step-by-Step Guide to Using the GRO+ Advanced Dermaroller
Begin by sectioning your dry or damp hair using clips so you can access all areas of the scalp. Start at the crown and work in small, manageable sections. Hold the dermaroller at a comfortable angle and apply very light pressure — let the weight of the tool do the work. Roll vertically (front to back) and horizontally (side to side) in each area, about 4–6 times per direction. Aim for a total of 1–2 minutes across the entire scalp.
Avoid rolling over the same spot more than 8–10 times; overdoing it can cause unnecessary irritation. The goal is to feel a light prickling sensation, not pain. If you experience sharp discomfort, you are pressing too hard. After completing the entire scalp, take a moment to gently massage the area with your fingertips to further stimulate blood flow. Do not apply any other product yet — the micro-channels are open and need the right serum next.
- Section hair with clips for full scalp access
- Roll vertically and horizontally 4–6 times per area
- Use light pressure — the roller’s own weight is enough
- Limit total rolling time to 1–2 minutes
Post-Microneedling Care for Best Results
Once you have finished rolling, immediately apply a serum or treatment to the damp scalp. The GRO Hair Serum is an excellent choice because its formula of micro-encapsulated growth factors and natural ingredients can penetrate deeply into the micro-channels. Apply a few drops directly to the scalp and gently massage with fingertips. This step delivers concentrated actives directly where they are needed most.
To support your results from the inside out, consider taking the GRO+ Advanced Hair Growth & Density Supplements consistently. These chewable supplements provide key vitamins and nutrients like biotin, zinc, and saw palmetto that nourish hair follicles. For the next 24 hours, avoid sun exposure, vigorous exercise that causes heavy sweating, and applying any harsh chemical products (like color or perm treatments) to your scalp. Clean your dermaroller immediately after use by rinsing with hot water and soaking in alcohol again.
- Apply GRO Hair Serum immediately after rolling to maximize absorption
- Take GRO+ Advanced Supplements daily for internal support
- Avoid sun, sweat, and harsh chemicals for 24 hours post-treatment
- Sanitize the dermaroller after every use
Tips for Safe and Effective Use
Consistency and safety go hand in hand when using a dermaroller. For most people, once per week is the ideal frequency. Give your scalp a full seven days to heal and regenerate between sessions. Replace the needle cartridge every 4–6 weeks to ensure sharp, clean needles. Never share your dermaroller with anyone, and always store it in a clean, dry case.
If you have any scalp conditions such as psoriasis, eczema, open wounds, or active acne, consult a dermatologist before starting microneedling. Also, avoid wearing tight hairstyles like ponytails or braids for a couple of days after treatment, as tension can irritate the freshly treated scalp. With patience and proper technique, you will begin to notice improvements in hair thickness and scalp health within a few months.
- Start with once-weekly sessions and adjust based on sensitivity
- Replace needle cartridge every 4–6 weeks
- Consult a professional if you have scalp conditions or medical concerns
Incorporating the GRO+ Advanced Dermaroller into your weekly hair care routine can be a game-changer for achieving thicker, stronger hair.
