FAQ

Yes. The clinical evidence is clear. Multiple independent scientific reviews confirm that LLLT significantly increases hair density and diameter compared to sham devices, in both men and women.

The largest independent review to date (2024) analysed 26 separate clinical trials involving 1,638 patients. Not one study. Not a brand claim. Independent science.

One thing we will always be straight with you about: LLLT works best in the early to mid-stages of hair loss when follicles are thinning but still active. It will not regenerate follicles that have completely stopped. No device will. If a company tells you otherwise, walk away.

For the full breakdown of the research, see our Learn page.

Yes. The Grow Laser Cap is FDA cleared for the treatment of pattern hair loss in men and women. FDA clearance covers 650nm laser diode therapy; the wavelength at which the clinical evidence for hair regrowth has been established.

This is a regulatory determination, not a marketing claim. Some devices on the market claim to promote hair growth without FDA clearance or use LEDs rather than laser diodes and rely on approvals that do not apply to their actual technology.

No. There is no cure for hair loss, and you should be very wary of any company claiming otherwise.

What Grow Laser Cap does is stimulate all hair follicles to grow at their optimum thickness and strength. Hair follicles that are in the early to mid-stages ofminiaturisation have the best chance to be rejuvenated to their optimal
condition.

Grow Laser Cap does not stop your body producing DHT, which is what effects your hair follicles if you are experiencing androgenetic alopecia (please refer to learn section of the website). Once you reach your optimal regrowth after 12-15months of continual use, you will need to continue regular maintenance sessions to ensure you maintain the regrowth you have achieved.

Yes, it will, but it depends on where you currently are with your hair loss and what is realistically achievable for you. Understanding the current condition and health of your hair follicles is the most important starting point.

The photobiomodulation (PBM) technology in Grow Laser Cap has been clinically shown to rejuvenate hair follicles in the early to mid-stages of miniaturisation, while also
strengthening existing hair and increasing the density of established hair. Unfortunately, follicles that have miniaturised to a very small level, where hair shafts are barely visible to the naked eye or a bald spot has formed, will not be able to be rejuvenated to their optimal condition. There is no device or treatment that can achieve that, and we will not pretend otherwise.

That is why it is important to take the free online consultation or speak to a member of our client service team before purchasing. We will identify where you are in relation to your concern and give you realistic expectations of what Grow Laser Cap's laser phototherapy can achieve for you specifically. The earlier you act, the better the result.

Yes, and there is specific clinical evidence for women, not just men. Several randomised controlled trials have been conducted exclusively on women with female pattern hair loss and consistently show significant improvements in hair density and diameter.

Women typically experience diffuse thinning across the crown and a widening part rather than a receding hairline.

This pattern responds well to LLLT because the follicles are still present, just under-stimulated. If you are unsure whether this applies to your type of hair loss, book a free consultation and we will give you a straight answer.

Grow Laser Cap's photobiomodulation (PBM), also known as low-level laser therapy (LLLT), exposes your hair follicles to low levels of red and near-infrared light at clinically proven wavelengths.

The Grow 280 and Proflex 302 operate at 650nm, while the DualWave 312 uses both 650nm and 808nm. These calibrated wavelengths of laser light penetrate the scalp to rejuvenate cells and stimulate cellular metabolism at the follicle. LLLT combats hair loss by extending the growth phase of the hair cycle while reactivating miniaturising follicles back to their growth potential. PBM increases nutrient and oxygen-rich blood flow to the hair follicles, ensuring the follicle matrix has the nourishment for the hair shaft to grow at its thickest and fullest.

It is non-thermal, meaning the light generates no heat, so there is no damage to the scalp or surrounding tissue.

No. Grow Laser Cap uses 100% medical-grade laser diodes. LEDs emit non-coherent, scattered light that does not consistently penetrate to the depth of the hair follicle. Laser diodes emit coherent light that travels in a focused beam directly to where it needs to go. This distinction matters clinically. The randomised controlled trials supporting LLLT use laser diodes, not LEDs.

If a device does not specify laser diodes, assume it uses LED.

Yes, and the clinical evidence supports combination therapy. A 2024 randomised controlled trial found that combining LLLT with minoxidil produced better results than minoxidil alone.

Grow Laser Cap is drug-free and non-chemical, so it does not interact with topical or oral hair loss medications.

Most people notice a reduction in shedding around weeks 8 to 12. Visible regrowth typically begins from 4 to 5 months, with the best regrowth results seen after 12 to 15 months of consistent use. Hair grows slowly, roughly 1cm per month, so patience is part of the process. Take a photo before
you start so you have an honest baseline to compare against. The difference is often more visible in photos than in the mirror.

Grow Laser Cap 280: 30 minutes, three times per week.

Grow Laser Cap Proflex 302: 6 minutes per day.

Grow Laser Cap DualWave 312: 6 minutes per day.

All caps have a built-in timer that shuts the device off automatically when your session is complete. Consistency matters far more than intensity. Regular sessions over months is what drives results.

The DualWave 312 is our most advanced cap. It uses 312 medical-grade laser diodes across two wavelengths, 272 diodes at 650nm and 40diodes at 808nm.

The 650nm lasers work in the red light spectrum, stimulating cellular metabolism at the follicle, extending the active growth phase of the hair cycle, and increasing nutrient and oxygen-rich blood flow to the follicle. The 808nm near-infrared lasers penetrate deeper into the scalp, reaching the lower structures of the follicle that red light alone does not consistently reach.

Together, both wavelengths work to reactivate miniaturising follicles, improve follicle health, and give the hair shaft the best environment to grow at its thickest and fullest.

If you are trying to decide between the single wavelength caps and the DualWave 312, the honest answer is that more coverage at proven wavelengths gives more follicles the best chance of responding. The DualWave 312 is the option we would recommend if budget allows.

We will beat any Australian or New Zealand retailer's price on any comparable FDA-cleared laser cap with a minimum of 272 medical-grade laser diodes (Grow 280). If you find one, contact our client service team.

The comparison has to be like-for-like. We are not matching devices with double-digit diode counts just because they carry a similar price tag.

Grow Laser Cap comes with a 2-year manufacturer's warranty. If anything goes wrong, email clientservice@growlasercap.com and we will either repair or replace your unit at no charge.

The Grow Laser Cap 280, Proflex 302 and Dual Wave 312 all come with a 12-month satisfaction guarantee. If you are not satisfied with your results after 12 months of use, contact our client service team and they will arrange a satisfaction refund. Hair regrowth takes time, which is why the guarantee runs for 12 months rather than the 30 or 60 days you see from most companies. We want you to have enough time to actually see what this device can do.

Because we would rather offer three products we are confident in than a broad range we are not. Our goal was to build the best-value, highest-diode-count, FDA-cleared laser cap available in the World and price it so that quality was not only accessible to people who can afford to spend thousands. We get frustrated seeing inferior products with double-digit diode counts priced nearly as high as ours. Best product, better laser coverage, discreet and even better price. We like to leave the space helmets to the sci fi conventions along with the keeping the LED lights on the Christmas tree.

It depends on the model. The Grow Laser Cap 280 and Proflex 302 operate at 650nm. The Grow Laser Cap DualWave 312 uses two wavelengths, 650nm and 808nm, which is why we call it dual wave technology.

650nm sits in the red light spectrum and is the wavelength used in the clinical research demonstrating efficacy for hair regrowth. It is also the wavelength at which our FDA clearance was approved. 808nm sits in the near-infrared spectrum and penetrates deeper into tissue, targeting the follicle from a different angle. The combination is designed to stimulate cellular activity more thoroughly than a single wavelength alone.

If it sounds too good to be true, it is. There is no device, drug, or treatment that can fully restore hair lost to advanced follicle miniaturisation, short of a hair transplant. Companies making those claims are counting on you not knowing that. We have seen too many people spend money elsewhere based on false promises and arrive at us disappointed. We would rather tell you the honest version upfront and let you make an informed decision.

The only way to fully grow back your hair after you have lost it is to undertake a hair transplantation or wear a toupee.

Hair loss is all we do. We are specialists, not a general health and wellness brand.

You can speak to a real specialist before and after you purchase. Not a chatbot. Someone who actually understands your situation and will give you a realistic expectation of what you can achieve.

We also offer the most competitively priced FDA-cleared laser cap on the Australian and New Zealand market, backed by a price beat guarantee and a 12-month satisfaction guarantee.
