Microneedling for Hair Loss: Does it Really Work?

Key Takeaways

• Microneedling may boost hair growth when paired with minoxidil, but the proof for using it alone is weak.
• The best technique is still unproven, and microneedling brings pain, bleeding, and a few days of downtime.
• Limmer Hair Transplant Center does not offer microneedling. We use FoLix, an FDA-cleared laser that employs the same healing principle with no bleeding and no downtime.

In-office microneedling for hair loss typically uses a small handheld device or “pen” in which a single-use cartridge covered in tiny needles is inserted; these needles are used to create precise micro-injuries in your scalp, which generates new blood flow and healing signals near the hair follicle. Paired with topical minoxidil, a common hair growth treatment, studies show real gains in hair growth.

At Limmer Hair Transplant Center, we do not offer microneedling at this time; however we do offer FoLix laser treatment instead, which uses the same healing idea with less pain and no downtime.

What Is Microneedling for Hair Loss?

Microneedling is a procedure that uses fine needles to prick the scalp. A true mechanical microneedling treatment is an in-office procedure that uses specialized pens and their corresponding microneedling tips to create vertical channels in the skin – imagine stamping a tip covered in needles into the skin. These pens typically allow for precise adjustment of the needles’ penetrating depth. Sessions are often preceded by numbing the scalp and generate pinpoint bleeding from the trauma; they are usually accompanied by topical application of hair growth treatments such as minoxidil. These tiny puncture wounds in the scalp trigger your body to heal; this process can support weak follicles in growing thicker hairs.

Few articles discuss the use of a more advanced technique called radiofrequency microneedling for hair growth, though this technique has not made its way to the mainstream yet.

Conversely, at-home “microneedling” typically refers to use of dermaroller devices. These look like small paint rollers covered in needles and are much less precise than in-office microneedling treatments. Dermarollers, as the name implies, roll needles across the scalp creating elongated channels of varying depths. These tiny tears in the skin can be more damaging and less effective.

How Does Microneedling Work?

Microneedling works by activating your skin’s natural healing response. The tiny wounds created by these needles have to be healed. In the process of healing, your body naturally recruits more blood flow, which brings oxygen, nutrients, and healing cells to the treated area. This same process may be leveraged to help revive follicles that have slowed down.

These healing cells, like platelets found in our blood, are triggered to release molecules such as growth factors to heal the injured skin. Two important ones are PDGF (platelet-derived growth factor) and VEGF (vascular endothelial growth factor). These proteins help your tissue heal, while nearby hair follicles benefit from their presence and are supported in growing new, stronger hairs.

While open, the physical channels created in the skin by microneedling can also help topical medicine soak in deeper so that more of it reaches the follicle.

Do Dermarollers Actually Work for Hair Growth?

The honest answer is: sometimes, but mostly as a partner treatment. Used alone, dermarollers have weak results, but when paired with minoxidil, the results look much stronger.

The most cited proof comes from a 2013 study in the International Journal of Trichology. Researchers split 100 men with pattern hair loss into two groups. One group used 5% minoxidil twice a day. The other used the same minoxidil plus weekly microneedling. After 12 weeks, the microneedling group grew far more hair, with their mean hair count rising by about 91 hairs. The minoxidil-only group gained about 22. And 82% of the needling group saw more than 50% improvement, versus about 4% of the other group.

A 2026 trial of 245 women used a shallow device every two to four weeks. It found no extra benefit over minoxidil alone. So, results depend a lot on depth and technique.

If you already use minoxidil or another topical, microneedling may help it work better, but it is a helper, not magic.

How Deep Should the Needles Be, and How Often?

Studies have shown benefit at needle depths from 0.5 mm to 2.5 mm. Most at-home rollers are on the shorter end of this spectrum, but deeper is not always better.

Deeper needle depths raise the risk of pain, bleeding, and injury. Most experts suggest needling about once a week or every two weeks for a sensitive scalp.

Here is the catch though: the science is not settled. Researchers still do not agree on the ideal depth or how often to needle. Some question whether depth should change based on how much hair you have lost, among other factors.

Until better studies answer these questions, it is hard to generate the best plan.

At-Home Dermarollers vs. Professional Microneedling

As previously elucidated, clinics that offer microneedling, be it mechanical or radiofrequency, use standardized, adjustable, precise tools with a new, sterile microneedling tip. At-home dermarollers are less expensive and more readily accessible, but they use short needles, create channels of varying depths, and the line between tissue damage and efficacy can depend heavily on your technique.

The table below summarizes the main differences between at-home dermarollers and professional microneedling in a clinic.

What Are the Downsides of Microneedling?

Microneedling can have some real drawbacks. The biggest complaints are pain, bleeding, and downtime. These are the main reasons Limmer chose a different path for our patients.

• Pain: A session lasts up to 45 minutes. That is longer than the 3 to 5 minutes of needle sticks with PRP. The scalp has many nerve endings, so it can hurt.
• Numbing limits: Numbing cream helps, but it must be wiped off fully first. If not, the needles can push it deeper into the skin, where it has not been deemed safe. Numbing shots add more sticks and more time.
• Bleeding and downtime: Microneedling causes bleeding. You may need a few quiet days to heal before your next activity.
• Unclear technique: The best depth and schedule are still unproven, so results can vary from person to person.

A Better Option at Limmer: FoLix Laser

Because of those downsides, Limmer Hair Transplant Center does not offer microneedling. We offer FoLix instead. FoLix by Lumenis is the first FDA-cleared laser device for hair loss. We like to conceptualize the mechanism of action as high-tech microneedling.

FoLix uses gentle laser pulses to make tiny warm zones under the skin. This starts the same healing response as microneedling. It boosts blood flow and growth factor release to support hair growth. It does not damage the top layer of skin, so there is no bleeding and little discomfort.

Most patients need four to six sessions, spaced about four weeks apart. Each session takes about 30 to 45 minutes with no downtime. Many people see their best results in three to six months. Like microneedling, FoLix works even better when paired with a topical hair growth medicine.

Can Microneedling or FoLix Replace a Hair Transplant?

No. These treatments can thicken thinning hair, but they cannot bring back follicles that are already gone. A hair transplant does that job. It moves healthy follicles from the back of your head to bald spots. FoLix and microneedling are best for holding on to the hair you still have.

Pattern hair loss in men is often measured on the Norwood scale. In the early stages, you likely have plenty of follicles to save. Women with thinning hair can benefit too. For advanced loss, a transplant or scalp micropigmentation may fit better. A specialist will be able to examine your scalp and help you choose the best hair growth treatment for you.

Frequently Asked Questions

Does Limmer Hair Transplant Center offer microneedling?

No. We do not offer microneedling because of the pain, bleeding, and downtime it involves. Instead, we offer FoLix, an FDA-cleared laser that uses the same healing idea with no bleeding and no downtime. Ask our team if FoLix is a good fit for your hair loss.

Can microneedling regrow hair on a fully bald scalp?

No. Microneedling needs living follicles to work. On a shiny, fully bald area, the follicles are usually gone for good. In those spots, a hair transplant that moves healthy follicles from the back of your head is the best option.

How long until I see results from microneedling or FoLix?

Hair grows slowly, so give it at least three to six months. Most studies run 12 weeks or longer before measuring change. Take monthly photos in the same light. That helps you judge progress, since day-to-day change can be hard to appreciate.

Can I use minoxidil and microneedling together?

Yes, and that combo has the best evidence. Just do not apply minoxidil right after needling. When performing at home, the study cited above instructed patients to wait about 24 hours after dermarolling to resume topical minoxidil so that their scalps could calm down. FoLix also pairs well with a topical medicine for stronger results.

Is at-home microneedling FDA approved for hair loss?

No. The FDA has not cleared any microneedling device for growing hair at home. Store rollers are sold as beauty tools, not medical cures. FoLix, by contrast, is the first FDA-cleared laser device for hair loss.
