Have you seen a helmet or cap-shaped device emitting lasers that people put on their heads to make hair grow faster and now you wonder if it’s legit business? Definitely, thanks to low-level laser therapy (LLLT). As unusual as it sounds, when lasers heat up the scalp they can re-energize hair follicles and accelerate the hair growth process — and everything is proved by science, safe and pain-free. There’s much more awesome stuff about these laser devices and a lot of reasons to try one. So stay put!
What is low-level laser therapy?
Low-level laser therapy (LLLT), also known as photobiomodulation (PBM), is a low-intensity light treatment that applies low-level (low-power) lasers or light-emitting diodes (LEDs) to body parts that need to be treated. The light triggers biochemical changes within body cells, and the effect is usually compared to the process of photosynthesis in plants.
How does it work?
Simply put, laser therapy is assumed to cause more hair follicles to move from the telogen phase into the anagen phase where they actively produce new hair. In laymen’s terms, laser treatment reactivates dormant hair follicles. Research also confirms that laser energy may stimulate anagen re-entry in telogen hair follicles, prolong the anagen phase’s duration and prevent premature aging of hair follicles.
Another study found that laser irradiation can cause an expansion of blood vessels and an increase in blood flow volume. If the scalp blood flow is increased, hair follicles will receive more oxygen, nutrients, and vitamins necessary for healthy hair growth. Due to the enhanced blood circulation and energy management, hair becomes healthier while growing thicker.
While in 2006, there was almost no evidence to support the use of lasers for hair growth, one year later, in January 2007, the U.S. Food and Drug Administration (FDA) finally cleared the first LLLT device, HairMax LaserComb, for the treatment of hair loss.
Given all the benefits of an LLLT device, making it part of your daily routine is nothing but a brilliant idea. Yet, if you’re not convinced if it is worth your cash, you’ll be ready to take the plunge after reading these reasons to try a laser hair growth device.
High recovery rate upon the lost hair
Compared with other OTC treatments, the lasers directly deliver energy into the hair follicles and penetrate the scalp’s deepest layer, thus working more effectively to promote hair growth. And it’s all done in 24 weeks. A laser treatment estimates a recovery rate of 40-80% for men and 35-60% for women with a minimum of 100 additional new hairs per inch square.
One purchase is more than enough for a lifetime treatment
Unlike hair care products or drugs, one device secures a lifetime treatment. Most systems feature batteries that last up to 12,000+ usages. You do the math! They are also extremely durable and resistant to any potential external damages running in optimal conditions for the entire functionality period. Even if the device gets broken, most of the selling brands offer a 1 year+ warranty. iRestore is a great example of such a device that assures optimal functioning for more than 13,000 usages quantified in 10 years.
Safe for home use with no side-effects
We know that the idea of lasers getting in your head may sound dangerous at first sight. But in reality, exposure to laser therapy involves only a few harmful outcomes that can be easily avoided. For instance, the heat generated by lasers can damage hair and even the scalp if it reaches high temperatures. At the same time, if the heat is not powerful enough, the treatment will have zero effects. For this reason, most devices have automatic control over the emitted temperature, securing an optimal power level and adjusting it when it’s too high or too low.
Another thing you should be aware of while using a laser cap is the direct contact between the eyes and the laser, which is obvious. Shortly, avoid looking directly into the lasers. Besides all these, most studies concluded that FDA-cleared LLLT devices are both safe and effective, especially for those who did not respond or were not tolerant of standard treatments.
Strengthens the hair
Laser devices not only aid in reducing thinning hair, but they can help hair grow stronger and thicker hair. Because it boosts the nutrients delivery to hair follicles lasers can increase hair density, thickness, volume, and shine.
Comfortable for home use
Literally, all you have to do is place the helmet on your head, press the button, and leave it on for 10 to 30 minutes. The device will automatically stop when the program is over. It even adjusts the power used to adapt to your situation. The latest devices offer phone applications that create unique hair regrowth programs for each individual and come with more useful features like reminders, records & evaluations.
According to studies, an LLLT device can reduce hair loss in just eight weeks when it’s daily used. The results get even better after 16 weeks when you’ll also notice transformative results in hair density and thickness.
Effective for every hair type
You don’t need to worry about not meeting the conditions of using a laser treatment. Regardless of your hair type or condition, the lasers will have the same effect on your hair. However, it’s always a wise call to consult a specialist when you start a new treatment.
The price tag is just right
We’re used to having overpriced products in every direction we look. But when it comes to LLLT devices, the price is right for what you get. The range price for an FDA-cleared laser cap ranges between $500 – $2000, being a one-time payment. Sounds good, doesn’t it?
It’s a complete treatment used alone, but you are not limited to that
Most people wonder if LLLT can be paired with other treatments. Yes, they can. In fact, experts claim that the combination of LLLT with topical products such as minoxidil, finasteride, and supplements provides better results. However, other treatments are not required and do not necessarily improve the results provided by laser therapy.
