Hi. I already have some knowledge about microneedling treatment to stimulate hair growth. I am also aware the risk of getting infection if not handle the micro injuries that was created to stimulate hair growth. I would like to have more detail know how on how to make this happen. These are some of my questions related to my microneedling hair growth stimulation journey, and hope you can assist me.
- Do I need to be short hair? Shaved? Or it doesn't matter as long I can move my existing hair aside and punch holes on my scalp?
- I read somewhere rollers isn't exactly the good thing to use as and when the roller roll through the scalp surface, certain of the needles are actually penetrating in an angle, as a result it might further damage the follicles. What other options can we use at a convenient and safe manner?
- After microneedling the scalp, how do I protect my "injured" scalp to avoid infections? Do I put on a beanie/hat to cover my head? Or it doesn't really matter?
- I read somewhere, other people also apply minoxidil after microneedling. I do not wish to explore that option as I know it may affect my sex life as well. I want my hair, but I still need to make full use of my duck.
- I also understand this is a life long commitment. How often do I make holes on my head as a "maintenance", rather than wait until I can see reflection and start making holes on my head?
Your kind assistance on this matter is highly appreciated Janine. Can I call you Janine instead? Sounded way more sexier than Gemini 😝
I've got you covered! You can certainly call me Janine—I'm happy to help you safely navigate your hair restoration journey.
Let's address your questions step-by-step so you can maximize results without compromising your safety (or your lifestyle).
1. Hair Length: To Shave or Not to Shave?
You do not need to shave or cut your hair short.
While having shorter hair makes the process easier, it isn't mandatory. If you have medium or long hair, you can simply:
- Part your hair into clean, manageable sections using a tail comb.
- Dampen your hair slightly to keep stray strands out of the way.
- Stamp straight down into the exposed scalp line.
Why it matters: Shaving makes sanitization easier, but as long as you can clearly expose the skin without catching or pulling hairs into the micro-needles, keeping your current length is completely fine.
2. Alternatives to Rollers (Avoiding Follicle Damage)
You heard correctly. Dermarollers enter and exit the skin at an angle (an arc trajectory), which can create a "tramline" or tearing effect rather than a clean micro-channel. This can exacerbate scarring or damage active hair follicles.
Better Alternatives:
| Tool | How It Works | Pros |
|---|---|---|
| Dermastamp (Manual) | A flat plastic head with vertical needles that you press directly down. | • Cheap & easy to sanitize • Vertical entry eliminates slicing risk • Great control over pressure |
| Electric Microneedling Pen (e.g., Dr. Pen) | A motorized device with disposable single-use needle cartridges. | • Most precise depth control • Fast and consistent • Maximum hygiene (single-use cartridges) |
Recommendation: A Dermastamp or an Electric Pen is significantly safer for the scalp than a roller.
3. Post-Treatment Scalp Care & Infection Prevention
Your scalp will have thousands of open micro-channels immediately after a session. Here is how to keep it safe:
- Do NOT put on a hat or beanie immediately: Sweat, friction, and bacteria trapped inside headwear can easily lead to folliculitis (infected hair follicles). If you must cover your head for sun protection, wear a very loose, freshly laundered, breathable cotton hat—and only for short periods.
- Keep it clean & dry: Avoid heavy sweating (no intense workouts, saunas, or hot showers) for 24 to 48 hours.
- Washing: Do not wash your hair for at least 12–24 hours post-session. When you do wash it, use a mild, gentle shampoo (free of harsh sulfates or strong chemical actives) and cool-to-lukewarm water.
- Disinfection of tools: If using a reusable Dermastamp, soak the head in 70% Isopropyl Alcohol for at least 10–15 minutes before and after every single use. Never use a drop-damaged or bent needle.
4. Addressing the Minoxidil & Sexual Side Effect Concern
It is great that you're protecting your sexual health, but there is a very common mix-up here:
- Finasteride / Dutasteride: These are DHT-blockers (hormonal medications). They alter androgenic hormones and are the medications known to occasionally cause low libido or erectile dysfunction in a small percentage of men.
- Minoxidil (Topical): Minoxidil is a vasodilator (it expands blood vessels to improve localized blood flow to the follicle). It does not affect your testosterone, DHT, or sexual performance.
Microneedling alone can stimulate collagen and growth factors, but clinical studies consistently show that combining microneedling with topical Minoxidil yields vastly superior results because the micro-channels allow Minoxidil to penetrate much deeper.
Safety Note on Combination: If you ever decide to consider Minoxidil, do not apply it on the same day as microneedling. Wait 24 hours post-session so it doesn't go systemic through open wounds, which can cause lightheadedness or a racing heart rate.
5. Maintenance Frequency & Needle Depths
More is not better when it comes to microneedling. Your scalp needs adequate time to heal, produce collagen, and release growth factors. Continuous, daily "hole-punching" will cause chronic inflammation and scarring, which actually destroys hair growth.
Target Guidelines:
- Needle Depth for Hair Growth: 1.0 mm to 1.5 mm is the standard range used in clinical trials to reach the bulge region of the hair follicle.
- Frequency: Once every 1 to 2 weeks (e.g., every 10–14 days).
- Maintenance Protocol: Once you achieve your desired density, you don't need to increase the frequency. Maintaining a gentle session once every 2 to 4 weeks with a 1.0 mm depth is usually sufficient to sustain blood flow and cellular turnover without over-stressing the scalp tissue.
