Let us start this discussion with the mention of a paradox.
Unwanted hair has become a predominant cosmetic issue for millions of people around the world. Modern aesthetics dictate that excess hair, especially on the body and near the genital region, is unsightly and should be removed on a persistent basis. The most popular methods of hair removal are temporary, and in individuals with coarse, curly hair, they can induce painful ingrown hairs and scarring. As a less abrasive alternative, hair removal specialists developed innovative technologies that offer patients less invasive and less painful hair removal alternatives. Laser hair reduction technology uses pulsed red, or infrared, radiation to remove unwanted hair by selectively targeting the melanin pigment in each strand. However, specialists noticed that under certain conditions laser light sources were able to stimulate anagen hair growth, which resulted in a marked increase of the patient’s hair.
So how useful is laser light at inducing hair growth in a controlled fashion?
Today we are going to talk about how laser technology can help with hair growth, a little bit about the science behind this innovative technology, and the reasons doctors everywhere are now recommending laser over chemical treatments for hair growth.
Just what do we mean by laser technology?
A laser device is that which is capable of emitting light through a process of optical amplification by stimulated emission of electromagnetic radiation. Since its fantastic discovery in the decade of the 60s, lasers have been used in optical drives, printers, scanners, DNA sequencing, communications, surgery, metalwork, speedometers, and in entertainment. How does it affect hair?
What exactly does laser light do to hair? In the year 2010, following a thorough and comprehensive study, the FDA authorized and approved Laser light technology as a measure to regulate hair loss in both men and women. Laser light technology now stands poised as an effective treatment of hair loss and has successfully reversed certain types of alopecia, either as a sole therapeutic tool or as part of combination treatments. In addition to the support this technology received from the FDA, it is now backed by more and more published studies that demonstrate its effectiveness.
The Low-Level Laser Light Threapy, also known as Low Power Laser, has been identified as a potential cure for specific hair problems such as Male Androgenetic Alopecia, Female Androgenetic Alopecia, specific scarring alopecias and. In the case of Alopecia Areata, Laser light is an extremely useful treatment option. This is significant because Alopecia Areata is a pathology that increasingly affects a more significant number of people and which, according to experts, is closely related to stress and the current pace of life.
HOW DOES LASER HAIR GROWTH ACTUALLY WORK?
The main advantage of low-level laser light technology for hair growth is that is works on the hair follicle directly. The primary mode of action is that the low power laser inhibits the process of follicle miniaturization that is commonly seen in most forms of alopecia.
To understand this further, we need to visualize that the hair follicle is susceptible to various pathologies and factors such as genetics, autoimmune diseases. Because the follicle is directly affected on a cellular level, it weakens rapidly and disproportionately. As a consequence, an inevitable shortening of the anagen phase of follicular growth occurs, and each individual hair strand is affected. When this happens, hair spends less time growing which causes it to fall prematurely.
The low-level laser light activates and accelerates mitosis and cell division while stimulating the formation of capillary networks in the scalp. All of this results in an increase in blood circulation of the scalp, which means more oxygen and other nutrients reach each follicle more quickly and effortlessly. In sum, laser technology provides patients an effective method to enrich, nourish and protects the hair follicle.
iRestore vs Capillus Which one is the Best?
Both iRestore and Capillus in summary, we can say that the capillary laser offers 5 crucial benefits:
- Increases the number of hairs because it stimulates the growth of new hair.
- It increases the diameter or the thickness of the hair because it improves the nutrition and oxygenation of the follicle.
- Increases the average hair density because it increases the duration of the Anagen phase compared to the Telogen, or shedding, phase.
- Removes excess fat, dandruff, and toxins from the scalp because it has an antibacterial effect.
- Stimulates the production of collagen because it counteracts the action of free radicals responsible for capillary aging.
As we said before, a low-level laser light hair device is especially indicated in treatments against Androgenetic Alopecia, the female and male types, specific scarring alopecias and most effectively to treat Alopecia Areata.
Although currently, its exact mechanism of action is not fully known, the grand majority of experts do agree on its efficacy in activating the blood circulation of the scalp and promoting capillary nutrition, which is essential in the Anagen phase of follicular growth. Additionally, it is a very pleasant method of treatment, completely painless and noninvasive, with no known observable side effects. For these reasons alone, doctors, physicians, and hair growth specialists, everywhere are recommending these types of products.
If you are noticing greater than usual hair loss or shedding, our advice is that you do not wait for the problem to become evident. Laser technology hair growth products are without a doubt one of the most effective, non-invasive, cost-effective, and convenient solutions to sudden, unexpected, and abnormal hair loss.
