Selecting a Hair Loss Treatment

Is Laser Therapy Right for Your Hair Loss?

Xtrallux Hair Regrowth caps are recommended for adults (men or women) who are experiencing mild to moderate hair loss due to androgenic alopecia with Fitzpatrick Skin Types I to IV as per indications for use. If your hair loss is advanced or due to scarring alopecias, this device is not right for you. Please consult with your healthcare provider for other types of hair loss (ie. medically-induced, areata, universalis, or totalis alopecias, effluvium, etc) and skin types.

Will laser therapy work for me if I'm bald?

Xtrallux is indicated for mild to moderate hair loss cases. If you're hair loss is advanced, you are not a candidate for laser therapy. Please read the indications for use on the product pages for detail.

Is laser therapy dangerous for dark skin tones?

Laser therapy at 650 nm and <5mW has never had any reported adverse effects for ANY skin tone, including the darkest of skin tones but due to limitations in testing protocols has only been clinically tested for treatment of AGA on skin types 1-4. Xtrallux devices are not cleared for dark skin tones due to the substantial equivalence process of FDA clearances.

Does laser therapy really work to treat hair loss?

Yes. The United States Food & Drug Adminsitration has cleared Xtrallux hair regrowth devices as effective for treating androgenetic alopecia (see full indication for use). The clearance is based on substantiation by earlier submissions to the FDA providing clinical data to verify that this type of medical device emitting red laser energy results in an increase in terminal hair counts over the course of time with continued use. Terminal hair is defined as long, coarse, well-pigmented hair which differs from vellus hair. 

Xtrallux manufactures devices use this technology which has been proven to increase counts of terminal hair in clinical trials accepted as substantiation by the FDA for prior clearances for this device classification.

Keep in mind that results will vary from person to person. Each case is different.

Product Information

What sizes are available?

Xtrallux Sizing / Fit

We have 4 models of devices currently on the market which each vary slightly in dimensions. All devices fit most and are somewhat flexible to provide comfort and adaptability to different head shapes. The Alpha and Super Plus models are our regular size caps, followed by the Turbo Pro which is slightly larger, and then lastly the largest is the Extreme RX. The following dimensions are approximate and express the interior dimensions when not placed on a head. While the overall circumference will be constant, the proportions will fluctuate between the width and length, depending on the shape of the user wearing the hat.

Model Length Width Circumference
Alpha 190 mm 170 mm 574 mm
Super Plus 190 mm 170 mm 574 mm
Turbo Pro 210 mm 175 mm 617 mm
Extreme RX 215 mm 185 mm 620 mm


Which Xtrallux model is right for me?

The main difference between our models is the density of lasers within the device. Higher-end models contain more laser diodes which are more closely spaced to each other for greater density of coverage. More lasers provides the scalp with more areas receiving treatment; for overall greater results with more lasers. You will likely notice results faster with the higher-end models as there are more areas of the scalp receiving treatment.

How often should I wear my Xtrallux cap?

The Xtrallux device should be used 6 minutes every day. Do not exceed recommended usage.  Exceeding recommended usage does not provide any added benefit and may, in fact, have a negative impact. For best results, use of the Xtrallux device should not be discontinued. If you inadvertently miss a treatment, restart your daily treatments. The Xtrallux device should be used indefinitely for continued treatment and maintenance of healthy hair growth. Cessation of treatment may result in reversion of results.

How many uses does my Power Pack last before needing to recharge?

A normal charge cycle for a new Power Pack with an Xtrallux Hair Regrowth Cap is ~3 uses (Alpha may get more uses, Turbo Pro may get less). Devices with more lasers may require more frequent charging as they consume more energy. Xtrallux Power Packs use lithium-ion batteries which allow for fast charging, longer life and reduced energy use. Lithium-ion battery cells degrade over time: more frequent charging may be required with battery aging.

Refer to the charging and safety instructions in your User Manual. Only charge Power Pack with Xtrallux provided AC adapter. Your Power Pack warranty covers any manufacturer defect during the first 12 months (accidental damage is not covered). Our power packs contain no user-serviceable parts. Please do not attempt to repair any portion of your device as this may result in device failure and void the manufacturer warranty. Replacement power packs can be ordered from Xtrallux as necessary during the device’s lifetime.

Can I charge my Xtrallux power pack anywhere?

Whether you are in New York or Tokyo, our universal AC adapter lets you recharge your Power Pack in most places around the world. Compatible with inputs of 100-240 V, 50/60Hz, 0.6A. We provide plug blades for power outlets using Type A, C (Euro), G, and I connections.

Should I part my hair during use?

Laser light typically shines through individual strands of hair to reach the scalp so you don't need to worry about parting your hair any particular way. Xtrallux Hair Regrowth devices emit coherent laser light which keeps the light energy narrowly focused at the surface to penetrate deeper and stimulate the hair follicle.

Can I user my laser cap with minoxidil or wet hair?

For best results, we recommend using the cap on a clean and dry scalp to allow for the laser light to penetrate without any obstruction from water or natural oils. 

If you decide to use with minoxidil on your scalp, we recommend cleaning the interior frequently to prevent accumulation of residue on the device that would block the light. Please refer to the maintenance instructions on the manual included with your device or see below.

Please note that there are no contraindications for using minoxidil with laser therapy. In fact, industry knowledge indicates that minoxidil may enhance the effect of laser therapy when used in conjunction so the use of multiple therapies is encouraged to maximize hair growth results.

Does Xtrallux laser therapy cap produce heat?

Xtrallux Hair Regrowth caps emit visible red light at ~655 nm in wavelength which does not carry heat. In fact, low-level laser therapy used by Xtrallux Hair Regrowth caps is often referred to as "cold laser" therapy because it differs from higher level laser light (such as infrared waves) which does produce heat.

It is normal to feel a slight warmth under the Xtrallux cap due to the electronics, as well as from natural body heat resulting from use of any hat. The electrical circuitry powering the laser produces a small amount of heat as a by-product. Additionally, the clear silicone liner insulates body heat naturally produced between the scalp and the interior surface of the device. Xtrallux devices give off no heat or harmful radiation. If you feel discomfort, please discontinue use and contact your doctor.

Is Xtrallux safe to use around young children?

The same eye precautions should be taken for children as adults. Please keep in mind that Xtrallux laser therapy is only recommended for adults.

This device is not intended for use by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the device by a person responsible for their safety. Children should be supervised to ensure that they do not play with the device or its accessories and components. Do not leave the device unattended while connected to Power Pack.
