Frequently Asked Questions

Yes. Capillus Laser devices only use clinically proven technology.

For example, the Capillus Pro model was validated in a double-blind, placebo-controlled clinical trial, published in Dermatologic Surgery. The trial found that after 17 weeks of use, participants saw a 51% increase in hair count — with zero side effects reported.

There have also been many other clinical trials that support the efficacy of low-level laser technology for treatment of androgenetic alopecia.

Please note that the results mentioned above are specifically for the Capillus Pro model. There have been no clinical trials to date on the other Capillus models to be able to assert an exact percent of average increase of hair.

Yes — and many doctors recommend it. Capillus helps protect and strengthen new grafts by stimulating healthy blood flow and cell activity. Always follow your surgeon’s guidance post-procedure.

Yes. Unlike some prescription medications for hair loss, Capillus low-level laser therapy (LLLT) products are safe for use by women.

Capillus is a drug-free, FDA-cleared solution suitable for both men and women with androgenetic alopecia. Many top hair restoration clinics recommend Capillus to women experiencing thinning or shedding.

While some Capillus models may seem expensive at first glance, there's a reason for it — and it starts with what's inside the cap.

Many cheaper "laser" caps on the market don’t use lasers at all — they use red LEDs, which lack the power and precision to effectively penetrate the scalp. While LEDs may work for certain light therapies, they’re not effective for treating hair loss.

Capillus uses medical-grade laser diodes (650nm or 808nm, depending on the model) to deliver focused light deep into the scalp, where it can actually stimulate follicle activity and promote real hair regrowth.

Capillus was also the first laser cap cleared by the US FDA for treating androgenetic alopecia. Every Capillus device is designed, engineered, and assembled in our ISO13485-certified facility in the USA, ensuring the highest safety and quality standards.

When it comes to your hair, don’t settle for less than clinically proven, doctor-trusted technology.

Capillus only uses medical-grade lasers — not LEDs. Here’s why that matters:

• Lasers penetrate deeper into the scalp for maximum follicle stimulation
  
• LEDs scatter light and don’t provide the same level of therapeutic intensity
  
• Laser light is collimated, coherent, and targeted — ideal for hair regrowth
  

Bottom line: Capillus delivers the light energy exactly where you need it — your follicles.

Most users begin seeing less shedding and fuller-looking hair around 3–6 months. The best results typically appear after consistent use for 6–12 months.

Just 6 minutes per day — it's that easy. Wear it while getting ready, watching TV, or checking emails. Consistency is key.

The primary differences between models lies in bluetooth connectivity, power, laser diode number, coverage, and of course price.

Capillus is FDA-cleared for androgenetic alopecia (pattern baldness), the most common type of hair loss affecting both men and women.

It is not designed for sudden hair loss, scarring alopecia, or hair loss due to medical conditions. That said, low-level laser therapy (LLLT) can still help stimulate follicle activity in many cases — but results may vary.

If you're unsure whether Capillus is right for your specific hair loss type, it's best to consult a dermatologist or hair restoration specialist.

Consistent use is key. Like brushing your teeth, laser therapy is a long-term commitment. Stopping treatment may allow hair loss to resume over time.
