In the ever-evolving world of hair care and restoration, you may or may not have heard about microneedling for hair loss. Promising to stimulate hair growth and combat thinning hair, the technique has received a lot of attention. But is it truly a solution for those seeking to restore their crowning glory? Dermatologists and hair experts share their thoughts on microneedling for hair loss—from what it is and if it works to alternatives you can try for hair regrowth.

What Is Microneedling?
Microneedling, scientifically known as percutaneous collagen induction therapy, involves using a handheld device with tiny needles to create micro-punctures in the skin. The process is meant to induce controlled micro-injuries, triggering the skin's natural healing response.
According to dermatologist Jodi LoGerfo, MD, “microneedling is widely recognized for its effectiveness in treating acne scarring, enlarged pores, wrinkles, and stretch marks, and has also been explored for its potential role in aiding hair growth.”
The effectiveness of microneedling on the scalp to help with hair loss and promote hair regrowth depends on a few factors and is not widely researched. “To me, the outcomes related to microneedling as a treatment for hair loss seem limited,” LoGerfo says.
“The effectiveness of microneedling for hair loss likely depends on the underlying cause of the hair loss and individual factors such as the severity of the condition and the patient's overall health," adds trichologist Isfahan Chambers-Harris, Ph.D.
Microneedling With Minoxidil
There are only two drugs approved by the FDA for treating hair loss—topical minoxidil and oral finasteride, though the latter is not approved for use in people assigned female at birth.However, used in conjunction with topical minoxidil, microneedling shows promise.
By creating microchannels in the scalp, microneedling helps enhance the absorption of topical minoxidil, potentially increasing its efficacy. Additionally, the micro-injuries induced by the needles may trigger a wound-healing response, leading to increased blood flow and collagen production around hair follicles, promoting thicker and faster hair regrowth.
Research has shown that a scalp treated with the combined therapy of microneedling and minoxidil showed greater results than one treated with minoxidil alone. “But this is mostly hypothesized—there are no great studies,” cautions LoGerfo.
Microneedling Procedure
For microneedling alone, a topical anesthetic is first applied for 30 to 60 minutes to numb the area. The anesthetic is then removed, and microneedling is performed using a pen or roller with needles on it. Multiple passes may be completed as required.
When combining microneedling with topical minoxidil, the same process is followed, but after the initial application of topical medication, additional passes of microneedling are performed to enhance absorption through the microchannels.
LoGerfo notes that microneedling for hair growth should only be performed by licensed professionals. Because the procedure involves breaking the skin, there is a risk of infection if not done correctly. Furthermore, combining microneedling with topical minoxidil could cause skin irritation, making professional guidance vital to ensure proper application and monitoring.
Treatment Length and Frequency
A microneedling session is relatively quick. You can expect to be in the provider's office for about an hour—the longest part is waiting for the anesthetic to kick in. Slight irritation is normal and should ease within a few hours.
The amount of microneedling treatments you receive depends on the root cause of your hair loss and its severity. Some people undergo monthly treatments, while others have weekly sessions. Generally, most folks are given at least three treatments and up to 12 within a few months. On average, the cost ranges from $200-$800 per session.
Post-Treatment Tips
While some swelling and soreness for a few days is normal, there are a few things you can do to minimize irritation and the risk of infection. Skip washing your hair for a few days. When you do wash, use a gentle, fragrance-free shampoo. Sleep on a clean pillowcase (silk is great for skin and hair), be extra gentle when brushing your hair, and wear sunscreen and/or a hat when in the sun to avoid getting a scalp burn.
Alternatives to Microneedling
Microneedling is not the only solution for hair loss. Other treatments, procedures, and hair products can aid hair growth.
PRP Treatment
Platelet-rich plasma (PRP) was originally a treatment that promoted healing in injured joints. Since then, it has emerged as a treatment to help regrow hair and improve the quality of existing hair.“There are virtually no side effects from PRP, except for a mild feeling of pressure at the injection site,” LoGerfo says.
During a PRP treatment, your blood is drawn and spun in a centrifuge to separate the platelets and plasma. Then, the plasma is injected into the scalp where hair loss has occurred to repair blood vessels, promote cell growth and wound healing, and stimulate collagen production.
“We began using PRP in dermatology after researchers found that high concentrations of platelets in plasma cells help promote hair growth by prolonging the growing phase of the hair cycle,” explains LoGerfo.
Chambers-Harris confirms that PRP has shown potential in promoting hair growth and increasing hair density in treated areas. “Injected monthly into the scalp, PRP therapy targets hair loss by activating the wound healing response, prolonging the hair growth phase, and ultimately leading to visible improvements in hair density after three to six months,” says Chambers-Harris.
Scalp Massages
While research is limited, derms say that one way to help support a healthy scalp—and practice a little self care—is to boost circulation. One way of doing that is with a scalp massage, using your fingertips or a handheld, rubber tool. Store a massager in your shower and use it when washing or conditioning your hair. This helps to increase blood flow (plus oxygen) to your scalp as well as reduce itchiness and flakes. The healthier your scalp, the better environment you create for your hair follicles.
Red Light Therapy
According to the American Academy of Dermatology, some studies show that with repeated treatments, it's possible for red light treatments to help regrow some hair over time. Choose from an "FDA-cleared", LED comb, cap, or helmet, and with consistent use, you may notice a boost.
Hair Serums
According to Chambers-Harris, hair growth serums can also help promote the healthy growth of new hair. “But always consult with your dermatologist or hair loss specialist to understand the root cause of your hair loss before attempting to treat it,” Chambers-Harris advises.
Frequently Asked Questions
How long before microneedling regrows hair?
Success rates for scalp and hair microneedling vary from person to person. It can take a few months before microneedling sessions start to show results. Generally, most people see some success in about 6 to 12 weeks, though microneedling is not a blanket cure for hair loss.
How much does microneedling for hair loss cost?
The cost of microneedling on the scalp ranges from $100 up to $800 per session. This wide range depends on where you live, how many sessions you require, and the severity of the issue. Remember, though, that it's important to have microneedling performed by a professional to avoid injury and serious side effects.
How long should I wait after microneedling to wash my hair?
After receiving a scalp microneedling treatment, you should wait at least four hours to wash your hair. Some providers recommend waiting up to 12 hours before washing your locks to allow healing to begin and avoid the risk of infection. Once you're ready, wash your hair and scalp with a gentle shampoo, and stay away from harsh chemicals.
