Have you heard of low-level laser therapy (LLLT), and now you’re curious about all the fuzz is making in the hair growth area? I still remember my reaction when I found that lasers can make hair grow the same way light helps plants grow. Yes, high-tech devices were designed to use LLLT to help people fight hair loss at home. Wait, are you not suffering from hair loss? That’s not an issue, you can still benefit from LLLT. Besides reducing hair loss, these devices can make your hair grow thicker, increase hair length, volume and density. All these lead to better hair quality and an improved appearance. There’s much more awesome stuff about these laser caps for hair loss and a lot of good 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.
Back in the days, low-level lasers were known to treat various medical conditions, such as stroke recovery, wound healing, nerve regeneration, and joint pain relief. But now, we can use them to make our hair grow faster! In fact, today, one of the most successful applications of LLLT is the stimulation of hair growth.
LLLT for hair regrowth
Low-level laser therapy is assumed to cause more hair follicles to move from the telogen phase into the anagen phase. When the follicles are in the anagen phase, they are actively producing new hair. If you suffer from hair loss or thinning hair, it might be because you have more follicles in the telogen phase, where they’re resting. Lasers feed light energy to the hair follicles and irradiate photons into the scalp tissues to speed up the growing process. Research also confirms that laser phototherapy may stimulate anagen re-entry in telogen hair follicles, prolong the anagen phase’s duration, increase rates of proliferation in active anagen hair follicles, 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 blood flow in the scalp is increased, hair follicles will receive more oxygen, nutrients, vitamins required for healthy hair growth. Due to the enhanced blood circulation and energy management, hair becomes healthier while grows quicker & thicker than usual — the inactive hair follicles become active again.
While in 2006, there was almost no evidence to support the use of lasers for hair restoration, 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. Studies confirmed that HairMax’s device increases hair density and leads to significant improvements in hair regrowth.
As I’ve said: there’s a lot LLLT can do for hair growth. And when you think you can get all the benefits with just a single device? Helmet, cap, comb, brush, it doesn’t really matter as long as it works with LLLT. What type you pick depends on your needs. Helmets and caps are more comfortable and fully cover your scalp, which means lasers will reach more hair follicles. Need more reasons to try a laser hair growth device? Here you go:
9 Reasons to Use a Laser Hair Growth Device
1. It has a high recovery rate upon the lost hair
Compared with serums or oils, the lasers directly deliver energy into the hair follicles and penetrate the scalp’s deepest layer. LLLT is also a research-backed treatment and does not lack scientific data in the treatment of hair loss. Research found LLLT as an effective treatment for androgenic alopecia that can stimulate hair growth, slows hair loss, and promote thicker feeling hair, better scalp health, and hair shine. And it’s all done in 24 weeks. A laser treatment estimates a rate of hair loss recovered of 40-80% for men and 35-60% for women with a minimum of 100 additional new hairs per inch square.
2. One purchase is more than enough for a lifetime treatment
Unlike hair care products and natural remedies, 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 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 if used daily.
3. It’s 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. The heat generated by the laser can damage the 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. 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.
4. It also strengthens and promotes new hair growth
Unlike your typical hair loss treatment with only one purpose of recovering the lost hair, LLLT can also grow new stronger, and thicker hair. Because it helps hair follicles receive more nutrients, lasers also increase hair density, thickness, volume, and shine. Even if you suffer from androgenic alopecia or alopecia areata, LLLT is extremely efficient.
5. It’s 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.
6. Lasers make your hair grow really fast
You can say the results are similar to the ones provided by professional clinical treatment. Studies found that a laser hair growth device can reduce hair loss in just 8 weeks when it’s daily used. The results get even better after 16 weeks when you’ll also notice an improvement in hair density and thickness.
7. Effective for every hair type and condition
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.
8. 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 excellent for what you get. A purchase like this may seem expensive, but considering you pay just once and your condition will actually be improved, it worths all the money. The range price for an FDA-cleared laser cap ranges between $500 – $2000, being a one-time payment. Sounds good, doesn’t it?
9. It’s a complete treatment used alone, but you are not limited to that
Most people wonder if they can use LLLT 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.
These reasons should be enough to convince you to get a laser device for hair loss. You can’t go wrong. It’s undoubtedly more affordable than a hair transplant and better than standard treatments. You’ll find many devices, but only a few are viable and FDA-cleared.
Fast facts about LLLT devices:
- More lasers don’t make hair grow faster, but they help provide better scalp coverage.
- LLLT reduces hair loss, promotes new hair growth, strengthens existed hair, increases thickness and density.
- FDA-cleared devices are safe for home use with little to no side effects.
