If you are among the 50% of Canadians who are struggling with hair loss, you have likely investigated Low-Level Laser Therapy (LLLT) for hair restoration, also referred to as laser hair growth therapy, and Laser Phototherapy (LPT).
Numerous studies have shown that laser hair growth therapy has the power to stop hair loss, thicken existing hair, and grow new hair.
It is no wonder that in the past ten years LLLT helmets have grown in popularity as an alternative form of hair loss therapy. These devices provide clinical-strength therapy and results from the comfort of your own home.
For devices that use actual lasers, this is exactly the case. However, a large majority of LLLT helmets use LEDs (Light-Emitting Diodes) in place of medical grade lasers, there is a big difference between the two.
Lasers and LEDs produce very different outcomes when it comes to hair restoration.
Many companies choose to either use LEDs exclusively or a mix of lasers and LEDs to cut costs since they are inexpensive and easy to make. Therefore LEDs are often used as on-off indicators in electronic devices. Lasers, on the other hand, produce an intense beam of light and meet scientific-grade standards.
To understand exactly how the effectiveness of a laser hair growth helmet compare to LED helmet, we need to look at three key factors where the two differ.
How Dos Low Level Laser Therapy Works
If you are experiencing hair loss, it means your hair follicles are no longer functioning optimally or getting the energy they need. This is where your mitochondria come in. Mitochondria are the power plants of your cells, and when they are revived or stimulated, your hair stays intact, and new hair can grow.
The challenge is that your hair follicles are deep below the surface of your scalp and restoring them requires a precise dose of energy to penetrate them.
Hair growth treatments must be able to penetrate your scalp all the way to the hair follicle, with the right type of light, in the right wavelength, and with enough power. This is where LED’s and Laser differs.
Light Coherence: LEDs vs Lasers
LEDs emit light in a range of wavelengths, rather than one specific wavelength. Additionally, the beam is incoherent and wider than a laser’s, so it cannot penetrate as far into the scalp.
Lasers on the other hand, emit monochromatic and coherent light, meaning it is a single-color wavelength, and the light waves are in phase.
The single wavelength makes laser light ideal for medical treatments because certain tissues (including hair follicles) only respond to particular wavelengths of light. Laser light’s coherence keeps the energy focused and the beam narrow, so that it can effectively penetrate deeper into the scalp and reach your hair follicles.
Wavelength: Lasers vs LEDs
According to the Swedish Laser Medical Society, 680 nm is the optimal wavelength of light for reaching and stimulating hair follicle cells. Since lasers deliver light at one specified wavelength, they can be targeted specifically for this wavelength.
Because LEDs are neither monochromatic nor coherent, they cannot target this specific wavelength and their beams do not actually reach the hair follicle. This makes them therapeutically useless when it comes to hair restoration.
However, it is important to note that Theradome is the only LPT/LLLT device that delivers the ideal wavelength of 680 nm! Every other LPT/LLLT device uses cheap lasers that are used for DVD’s and CD’s, and they are not medical grade lasers as they are used for the consumer electronics industry and NOT for hair growth.
Theradome, however, creates its own lasers right here in Silicon Valley, California specifically to deliver 680 nm wavelengths.
Power: LEDs vs Lasers
The final factor to consider is power. In order to effectively stimulate hair follicles, you need enough energy to reach them to produce a photo biomodulation effect.
Energy = power X time. And since light becomes more dispersed the farther it travels, you need a significant amount of power for the light to be strong enough once it reaches your hair follicle cells.
Since energy = power X time, the more powerful the laser, the more energy is produced, and in a shorter amount of time. This means that powerful lasers are not only more effective, they produce results in less time.
Lasers produce far more power than what LEDs are capable of. In fact, LEDs are simply not powerful enough to have a therapeutic effect when it comes to hair growth. To be specific, a laser can deliver about 150 times more joules than an LED, which means deeper penetration and at 680 nm wavelengths, this provides even deeper penetration.
Choosing a High-Quality Laser Hair Growth Device
To get real results, with the best outcome possible, always choose a hair restoration device that uses real lasers, not LEDs. And do your research when it comes to wavelength and power. As we just discussed, those two elements are key for effectively stimulating hair growth.
Theradome’s PRO LH80 laser hair growth helmets feature high-quality lasers that are created right here in Silicon Valley, California specifically to achieve the optimal 680 nm wavelength. They also deliver the most power (38.4 joules/cm2) of any LPT/LLLT device for maximum hair follicle stimulation and the most breakthrough hair restoration results.
