What Is Low Level Laser Therapy (LLLT)?

This laser treatment is viewed as the most modern hair regrowth treatment used to treat different hair loss conditions, such as androgenetic alopecia or male and female pattern hair loss.

It uses laser devices that produce non-invasive light to revitalize hair follicles under our scalp to stimulate hair growth. It also prevents thinning hair by minimizing hair shedding to make our hair much healthier and more long-lasting.

Laser treatment of hair loss has been approved by FDA as a medical treatment that allows the regeneration of human scalp hair and tissue repair under our skin.

Several reasons may provoke hair loss in adult men like us. Male androgenetic alopecia or male pattern baldness is one. But can this laser therapy promote hair growth even if it is caused by this kind of disorder?

Of course, yes! In fact, research shows that red light therapy can enable tissue rehabilitation and regeneration, making our scalp conducive again for healthy hair growth.

Additionally, it’s been proven to increase cell metabolism and proper maintenance of blood vessels in our scalp for thicker, fuller, and more resilient hair shafts. With that, it is definitely the best non-surgical option to treat male pattern hair loss to regrow your hair again.

Which Laser Hair Growth Devices Are Best?

There were plenty of laser devices in the market that you could choose from. Most of them are easy to use, affordable, and can be used in the comfort of your home.

One of the go-to options for people who want to reverse the effects of hair loss is the low-level light therapy caps. They are designed to be compact, lightweight, and portable for you to use anytime and anywhere you want.

Another popular choice for many is using laser combs as their laser treatment. They are user-friendly and designed to target specific areas of your head susceptible to hair loss to avoid hair thinning.

These devices vary in their effectiveness, price, and design. But whatever you might choose, always consider if that laser treatment product fits your budget and lifestyle. 

How Does Low Level Laser Therapy Work?

Low-level laser light therapy works by emitting a visible red light laser with a particular wavelength of light energy that penetrates the hair follicles under our scalp.

After penetrating the scalp, low-level laser light stimulates the stem cells found in our hair follicles to shift them back to the growth phase of the hair life cycle.

Apart from that, LLLT is believed to increase blood flow in our scalp to deliver vital nutrients and oxygen essential for regrowing hair to avoid hair loss.

It can also lessen excessive dihydrotestosterone (DHT) hormones buildup in our hair roots, making them an alternative yet effective treatment against male pattern baldness.

Hair Benefits From LLLT

Now that we know how this laser device works as a hair treatment for hair loss, it’s time for us to talk about the hair benefits.

Low-level laser light therapy has tremendous benefits against hair loss and hair regrowth as well. Here are a few of them:

Non-invasive. Cold laser therapy is a non-surgical hair loss treatment that uses a visible red light laser that penetrates the skin without feeling anything.

Safe. Most LLLT devices in the market have passed several clinical trials to ensure it is safe to use. Also, they are FDA-cleared to use as a medical treatment against hair loss.

No downtime. You can still comfortably do your daily routine and other activities after every therapy session without worries.

Increase hair strength. Besides aiding hair growth, it can also help produce healthy, strong, and thicker hair.

Quicker noticeable results. Studies show that laser therapy can stimulate hair growth much faster and more reliably versus other hair loss treatments.

Will Low Level Laser Therapy Work for All Types or Causes of Hair Loss?

Several factors can influence and trigger hair loss. These factors include genetic conditions such as androgenic alopecia, side effects of some medications, stress, and many others.

Thankfully, this exceptional laser treatment therapy can do wonders for almost every hair loss condition.

Red light therapy can also be used for other hair loss problems, such as hair loss due to chemotherapy and other health conditions.

How Long Does It Take To Grow Hair With LLLT?

As we said earlier, laser treatment can restore the beauty of your hair and prevent further hair loss as quickly as possible.

But this hair regeneration can’t happen in just a single night. Results may even vary from person to person.

However, with continuous therapy sessions, the average time you need to wait before you can see any noticeable results is around 2 to 3 months.

LLLT is an exceptional therapy that is proven to be effective. But to achieve favorable results, you need patience and proper knowledge of these laser products to maximize their full benefits.

How Do You Get The Best Results From LLLT Hair Growth Stimulation?

LLLT treatment has promising effects that can fix hair loss problems and help regenerate human scalp hair.

But to get optimum results, you must use it regularly. We recommend continuing your therapy sessions until you get satisfactory developments.

You can even combine LLLT and topical minoxidil or other medical treatments to amplify the results you want to achieve. Likewise, vitamins and supplements for hair growth can provide much more positive effects.

You may also opt to use LLLT devices as a maintenance therapy even after achieving adequate results to support improved hair growth that will last for an extended period of time. 

What Is The Difference Between Laser Vs LED Hair Growth?

Laser and LED are both excellent choices if you are looking for a hair growth device to resolve your hair loss problems. They have several similarities too. But what are their differences?

LED can emit light beams that can penetrate the scalp and stimulate hair roots. The light beams it can radiate are much wider and less consistent.

On the other hand, a laser can emit much more coherent light in a single wavelength. Its energy beam can be narrowly focused, making it more consistent and effective in reaching stem cells under our scalp.

Although both laser and LED can benefit our hair, laser-equipped devices are the clear winner here in this comparison.

LLLT Hair Growth Expectations

Low-level light therapy has extreme efficacy in treating hair loss problems, and that is a fact.

It helps facilitate the natural growth development of our hair for them to grow healthy, strong, and more vibrant.

However, LLLT cannot guarantee positive results for people with long-time baldness. Remember that for this therapy to perform, you need to have an active hair follicle on your scalp for it to do its work.

That is why it is ideal for people to begin their cold laser therapy as soon as possible to halt further hair loss and start the healing process.

LLLT Hair Growth Side Effects

We will be totally honest with you. Not all can experience this, but this treatment for hair loss might cause some side effects.

Side effects such as redness and itchiness in the scalp may occur. Increased hair shedding is also reported by some of its first-time users.

But here’s the thing, do not worry. These after effects are minor and would resolve on their own after a month of use. In fact, these symptoms are indications that this treatment is working on you.

Will Low Level Laser Therapy Cause Hair to Grow in Other Unwanted Places?

Keep in mind that laser therapy treatment will only halt further hair loss and won’t create new hair growth where there was previously none. 

It can, however, help stimulate the entire hair follicle that has stopped producing hair or has been growing very small and thin.

This can lead to healthier hair growth in those areas. Just remember that laser therapy won’t cause hair to grow where it never existed before.
