Best hair growth devices: LED, laser & microneedling therapy

If you’ve started to notice your hair thinning, your hairline receding or signs of pattern balding, then it may be time to explore clinic-grade hair regrowth technology for real, professional-level results.

While treatments like laser therapy and microneedling are proven to support regrowth, LED red light therapy helmets are quickly becoming the gold standard for safe, convenient and effective at-home hair restoration.

Let’s explore how these science-backed technologies work and why LED therapy for hair growth could be the easiest way to kickstart your growth journey. 

LED therapy for hair regrowth

Also known as Low-Level Light Therapy (LLLT), LED light therapy uses targeted wavelengths of light to increase blood flow to the scalp and reawaken inactive hair follicles. It’s a non-invasive, FDA-cleared treatment, clinically proven to encourage regrowth and boost hair density.

How does it work?

Red light at 640nm penetrates the scalp at the ideal depth for reaching the follicles to:

• Boost cellular activity, increasing the production of APT (the energy that powers cells) to activate and strengthen hair follicles.
• Extend the anagen (growth) phase of the hair cycle, causing strands to grow longer and thicker.
• Improve circulation by widening blood vessels, delivering more nutrients to follicles.
• Reduce oxidative stress and inflammation, common contributors to hair loss.

Why choose LED for hair growth?

• Clinically proven: Shown in studies to significantly increase hair density.
• Convenient: Treatments are hands-free and painless, lasting just 10 minutes.
• Comprehensive: Covers your entire scalp for full, optimal coverage.
• Supports overall hair health: Strengthens the scalp for healthy hair growth.
• Safe: FDA-cleared wavelengths with no downtime or side effects.

Our recommended treatment plan:

The CurrentBody Skin LED Hair Regrowth Device is clinically proven to increase hair count by 123% in only 12 weeks.

FDA-cleared and powered by a spectrum of red light wavelengths (620-640nm), this LED hair growth helmet increases blood flow to affected hair follicles, boosting scalp health, strengthening hair follicles and extending their growth (anagen) phase for newer, thicker hair regrowth.

For best results:

• Complete daily, 10-minute sessions for 16 weeks.
• Expect visible improvements within 6–8 weeks (depending on your hair cycle).
• Enjoy hands-free treatments while connected to Bluetooth for uninterrupted listening.
  

Laser therapy for hair regrowth

Laser therapy, often called Low-Level Laser Therapy (LLLT), uses concentrated laser beams to reach deeper into the scalp. Unlike LED light, which reaches the whole scalp, laser devices target hair follicles at their root with a more precise beam. This means LLLT can penetrate slightly deeper, but they often treat smaller areas at once.

How does laser therapy work?

LLLT works through a process called photobiomodulation, which uses light energy to boost hair follicles, helping them to function better. 

The laser light supports blood flow and energises dormant follicles, kickstarting the regrowth process. Over time, this not only activates growth but also strengthens and thickens existing hair for a fuller, healthier look.

Who is it for?

If you’re battling pattern baldness or hereditary hair loss, laser therapy could be a great option. It's clinically proven to increase hair density and reduce thinning, making it an ideal option for those seeking a targeted, science-backed solution to restore hair.

Why choose laser therapy?

• Clinically supported: Proven to enhance density and reduce thinning.
• Deeper penetration: Focuses on follicle roots.
• Targeted use: Good for smaller thinning areas.

Laser therapy can be highly effective, but treatments may require more frequent or longer sessions. 

Medical guidance is recommended if you have scalp conditions or health concerns.

Clearing up the confusion: Light vs laser terminology

While both Low-Level Light Therapy (LED) and Low-Level Laser Therapy (Laser) are often shortened to LLLT, the two technologies are not the same.

Here’s the main difference:

• Low-Level Light Therapy (LED): Uses light-emitting diodes (LEDs) to cover a large area of the scalp evenly.

• Low-Level Laser Therapy (Laser): Uses coherent, concentrated laser beams to penetrate more deeply over a smaller area.

Microneedling for hair growth

Microneedling involves using a dermaroller or microneedling pen with tiny needles to create micro-punctures on the scalp, causing a slight tingling sensation during the treatment. 

These tiny, controlled injuries trigger the body’s natural healing process, boosting collagen production and enhancing the absorption of topical treatments, supporting healthy hair growth.

Why try microneedling?

• Affordable: Can be done at home or professionally.

• Effective: Enhances the impact of topical regrowth solutions.

• Science-backed: Studies show it improves density and thickness.

What to expect

Microneedling is best used as a supportive treatment alongside LED therapy, rather than a standalone option. It requires consistency (1–2 times per week), device sanitisation, and may cause mild scalp redness.

Check with your doctor if you have bleeding disorders, scalp infections or other health concerns before using microneedling devices.

 

Comparison: LED vs Laser vs Microneedling

Device Type	Method	Benefits	Considerations
LED Light Therapy	Red LED light (640nm) energise follicles and boosts scalp health.	Covers entire scalp, safe for home use, clinically proven and FDA-cleared	Requires consistent use for best results.
Laser Therapy	Concentrated low-level laser beams energise follicles and boost scalp health.	Clinically proven and able to penetrate deeper than LED.	More expensive and the smaller coverage area means sessions may be longer.
Microneedling	Tiny punctures boost collagen production and product absorption.	Supports scalp health and increases topical absorption.	Requires careful technique and isn’t suitable for all scalp conditions due to risk of irritation.

 

Before starting any hair regrowth treatment, it’s best to consult with your doctor or dermatologist, especially if you have underlying scalp conditions, are taking medications, or are unsure about which technology is right for you.

Choosing the best hair growth device for you goals

Now that you’ve seen how LED, laser, and microneedling compare, the next step is choosing the right hair regrowth device for your goals.

• LED light therapy helmets (often called the best LLLT devices for hair loss) are ideal if you want full scalp coverage, hands-free use, and proven clinical results.
• Laser hair growth devices can work well for targeted areas of thinning, but usually take more time and investment.
• Microneedling tools are best if you’re already using serums and want to boost their effectiveness
