The use of laser therapy in the treatment of hair loss is a topic that is becoming more and more studied.
In recent years there have been many different clinical studies that have shown the effectiveness of laser treatment in hair regrowth to varying degrees.
See below Let’s take a look at some of this research and also provide some background information on hair regrowth in general.
Introduction: what is laser hair restoration and how does it actually work?
Laser hair growth is a process in which light emitted by a laser stimulates cells to grow new hair to produce.
It’s not entirely clear how low-level laser therapy (or LLLT) works, but it’s thought to be one of the most promising forms of what’s called photobiomodulation therapy.
The use of laser hair restoration is a treatment that has grown in popularity in recent years.
It has been clinically proven to increase the rate of hair production and density, as well as stimulate natural hair growth.
And regrowth or restoration of thinning hair is not just a trivial or superficial matter: low self-esteem due to a receding hairline or Thinning scalps can lead to an unhealthy focus on one’s appearance or even social withdrawal.
Low-Level Laser Therapy: Laser caps to the rescue
Recent investigations (September 2021) from Thailand’s Chulalongkorn University found that LLLT works: It actually stimulates hair follicles and hair growth.
As Professor Ratchathorn Panchaprateep from the university explains, people suffering from thinning hair, hair loss and balding often have trouble finding the right treatments.
And this can be common Include changing shampoos, cutting their hair short, taking supplements, avoiding chemicals on the scalp. All without success.
One of the reasons for this failure, says Panchaprateep, is that the real causes of thinning hair and hair loss are not being addressed.
Kiierr laser caps, for example, allow you to Regrow hair follicles on your scalp safely and effectively using a low-level light therapy treatment that is FDA-approved and clinically proven to safe and effective.
Does laser hair regrowth work?
So, does laser treatment work for hair loss? Short answer: yes, at least in part.
For example, a 2017 meta-analysis – that is, a study that combined the results of several previous studies – concluded that Minoxidil, Finasteride (aka Propecia) and Low Level Laser Light Therapy (i.e. LLLT, often used in the form of laser caps) are all effective at promoting hair growthin men with androgenetic alopecia (also known as male pattern baldness).
The study, published in the Journal of the American Academy of Dermatology, also found that all treatments were the Superior to placebo.
More specifically, it was actually found that LLLT outperformed even minoxidil in terms of hair growth per square centimeter and essentially on par with finasteride.
Best of all, LLLT has none known en side effects, which is not the case with finasteride.
Another 2017 study published in the journal Dermatalogic Surgery found that there are currently nine publications in the PubMed database supporting the use of LLLT for hair loss associated with androgenetic alopecia document.
Five of these studies looked at comb devices and four looked at laser helmets or laser caps.
All studies reported positive changes in hair density after 16-26 weeks with LLLT compared to sham devices.
In fact, there is some evidence that the study found that LLLT outperformed both minoxidil and finasteride, at least in men:
Warning signs of excessive hair loss
“When more than 70 to 100 strands of hair fall each day out, this is a sign of abnormal hair loss. said Ratchathorn.
It’s normal, she explained, for a little bit of hair to fall out when you shampoo, blow dry or comb.
But she adds when You have hair loss during the day, for example during meals or at work, then this is abnormal.
Especially for men it can be difficult to notice this type of hair loss during the day. “You should notice if there’s hair on the pillow as soon as you wake up,” Ratchathorn said.
For men, thinning hair and hair loss usually starts at the front and goes into an over M-shaped hairline.Some men develop a bald spot on the top of their head that gradually spreads.
In women, thinning usually starts where the hair separates and gradually gets worse over time.
Main causes of thinning hair, hair loss and baldness
Ratchathorn says up to 40% of adults suffer from thinning hair, balding and hair loss.
And this percentage is increasing, most likely due to a combination of stress, weather conditions and a poor diet. Other factors include excessive sun exposure and vitamin deficiencies.
Hair problems and balding can affect both women and men, but for men, problems start at an earlier age and are in usually more extreme than in women.
Main types of hair loss treatments: pills, creams or laser hair treatment
Currently there are three main treatments for hair loss: Medications such as finasteride (which slows down hair loss) or Minoxidil (which makes hair thicker) and Hair Transplant, in which hair is transplanted from a denser area.
But lately, a newer treatment called low-level laser therapy (LLLT) has been gaining popularity.
It uses alaser cap or comb. These hair growth caps and combs are low-level laser therapy devices that emit red laser light to gently stimulate the hair follicle cells.
They are suitable for people with thinning hair in the early to moderate stage.
The devices are portable and can be used at home.
Using such a device for 15 minutes a day strengthens the hair follicles and creates new and thicker hair growth.
Ratchathorn said her research shows that results occur after about five sessions and that more noticeable results are visible after three months.
Background: Hair Loss and Stress
Harvard University researchers have identified the biological mechanism behind how chronic stress affects the stem cells of hair follicles, which confirming the notion that stress can lead to hair loss.
In a study published in March 2021 in the journal Nature, researchers found that a key stress hormone causes hair follicles -Stem cells “stay in a prolonged state of dormancy” without regenerating new hair.
Researchers identified the specific cell type and molecule responsible for this problem and showed that it could potentially be targeted to restore hair growth.
Hair follicles turn up naturally between growing seasons and resting.
During the growth phase, the hair follicle cells regenerate the hair and the hair gets longer every day.
During the resting phase, the stem cells are “dormant”. and hair can fall out more easily. Hair loss can occur when hair falls out and stem cells remain dormant without regenerating new tissue.
Under normal conditions, hair follicle regeneration slows down over time – the dormant phase lengthens with age.
But when they removed the stress hormones from mice, they found that the resting period became extremely short and the mice would constantly enter the growth period throughout their lives to regenerate hair follicles, even when they were old.
“This finding suggests that elevated stress hormones actually have a negative effect on hair follicle stem cells,” said the study’s lead author, Harvard Professor Ya-Chieh Hsu. “But the real surprise came when we turned off the source of the stress hormones.”
Stress hormones had prevented cells beneath the hair follicles from secreting Gas6, a molecule that the researchers showed can activate the hair follicles Stem cells.
However, the addition of Gas6 was sufficient to activate hair follicle stem cells that were in the dormant phase, which promoted hair growth.
Researchers are currently investigating possibilities for a Cooperation further development and eventual commercialization.
Background: How can I recognize signs of male pattern baldness?
Male pattern baldness is the most common form of male pattern baldness. It is a hair loss condition that typically affects males who are genetically predisposed to it.
Male pattern baldness is characterized by a receding hairline and bald patches on the scalp.
Other signs include an increasing distance between the hairline and the forehead and/or a thinning crown (= less hair coverage) over the top of the head
The detection of hair loss in men varies from person to person. Some people only realize it when they start losing their hair. However, others may feel their hair thinning long before that.
Baldness occurs when the hair follicles do not produce new hair as quickly as it is lost.
The term “male pattern baldness” is somewhat misleading. It implies that the only pattern of male pattern balding is progressive thinning or a receding hairline, but in fact there are three distinct patterns, all occurring over time.
These are three types of male pattern balding : frontal, crown and crown.
Frontal means that the hairline recedes from the temple to the forehead; Crown means that the hair at the top of the back of the head and on the sides gradually thins out; Vertex means it starts at the back, which often leaves an “M” shaped patch on your head where there is no hair.
It is important to understand the signs and symptoms of male pattern balding in order to avoid it She can know if you are at risk for it or not.
The earlier you recognize a symptom, the greater your chances of preventing or stopping it from getting worse.
Conclusion: Does laser hair growth work?
More and more studies are concluding that yes, laser treatment actually works to regrow lost hair.
New scientific results on the effectiveness of laser hair restoration are published almost monthly.
The effects may not be dramatic, but they are significant, approaching and in some studies even Outperform traditional treatments like Minoxidil.
And unlike popular prescription treatments like finasteride (better known as Propecia), laser caps for hair growth have no known side effects.
In summary, that a laser hair regrowth cap may be the most promising new treatment for thinning hair right now.
Above we looked at the potential benefits of a hair regrowth cap viewed with a laser.
We have also considered some of the possible side effects associated with this treatment and other treatments.
While it’s not certain that a laser hair growth cap is the answer to your thinning hair problems, there are now more options than everfor people looking for growth are looking for their locks again.
