There are some rumors out there that claim that laser hair therapy causes shedding. If you’ve been reluctant trying out this revolutionary, 100% natural technology, we’re here to put your mind at ease. Regardless of what you may have heard or read, laser hair therapy does NOT cause shedding. And here’s why.
First, we’ll assume that the laser hair therapy device you’re using is actually legit– meaning it is NOT some type of gizmo manufactured in China, (such as caps, combs, bands and LED devices) which won’t be as effective to repair hair loss at a cellular level. Never forget that you need to deliver an optimal dose of energy to the base of hair follicles to see any sort of tangible results: minimized shedding, new hair growth and a thickening of hair shaft diameter are three well proven and documented results of laser hair therapy.
Back to the question at hand– why does a scientifically engineered laser hair therapy device NOT cause shedding? Let’s quickly run through the hair growth cycle to address this question.
If you’re healthy, your hair growth cycle functions optimally– meaning that 90% of your hair is in the growth (anagen) or transitional phase, while only 10% is in the resting phase (a.k.a.– the Hair Graveyard or in scientific terms, the telogen phase). Normally, every hair that ends up in the telogen resting phase eventually gets replaced by another, bright-eyed and bushy-tailed hair ready to pop right up in full vivacious bloom. Healthy hair usually stays in the anagen growth phase from two to six years.
If you’re suffering from hair loss for whatever reason, whether it be for medical reasons, types of medications which cause extreme shedding, or unfortunate passed-down genetics, the above statements no longer apply. The anagen phase lasts for less than two years, and there is a high probability that a hair in the telogen phase never gets replaced. That’s why you begin to shed more and more, and eventually develop the dreaded female or male baldness pattern, respectively measured by the Savin and Norwood scales.
An optimal laser hair therapy device does a few things when it comes to the hair growth cycle. First, hair that’s in the transitional phase (between the growth and resting phases), loses its arterial blood supply of nutrients– in a way, the hair bulb gets decapitated from the blood vessels that feed it. This is when it enters the telogen resting phase. The principles of laser hair therapy rely on substituting this nutrient supply of energy with light energy. By feeding energy to your hair follicles, you are in a way delaying the decapitation of hair bulbs from their blood supply of nutrients. As a result, the growth phase becomes elongated. This entails a shortening of both the transitional and resting phases.
Since the word “phase” is associated with a period of time, you’ve guessed it– with the right dosage of laser energy, these two phases become shortened, which means that, in our case, their pace increases. So for instance, a hair in the transitional phase enters the telogen resting phase a lot more quickly than per norm. This means that it’ll leave the resting phase just as quickly. In other words, laser hair therapy increases the pace of the transitional and resting phases. Hairs stuck in the resting phase hurry with frenzy to get replaced by new burgeoning hair follicles, born with a healthy, elongated anagen growth phase.
This is the part that is misconceived as shedding. Dead hairs (which are already dead, to state the obvious) do get cast away quickly but only to make room for healthy hairs. So yes, you may notice a bit more hair falling out when first undergoing laser hair therapy but these hairs belong to the telogen resting phase. You certainly don’t want these on your head, and their departure works in your favor as it implies the birth of anagen hairs.
Still not convinced? While you can’t differentiate between anagen and telogen hairs with the naked eye, you can take them in to a trichologist or dermatologist for scrutiny. Visualization techniques, such as microscopic analysis, as well as performing biopsies will show that an anagen hair has a longer shaft, a sebaceous gland, and a hair bulb at the base of the hair, which is developed in a dermal papilla. A telogen hair will have a much shorter shaft, no hair bulb (in fact it’s called a hair club), and has no sebaceous gland. Knowing how to differentiate between anagen and telogen hairs is actually extremely important in the field of hair transplantation.
So laser hair therapy does NOT cause shedding– in fact, it’s quite the opposite! A low-level laser applied to hairs at the beginning of the growth phase extends the growth phase. All other hairs are thus programmed to accelerate the birth of new, healthy hair follicles. This is also why laser hair therapy (again, with an optimal device), is such a powerful tool at fighting hair loss. Not only is it a 100% natural solution with zero side effects, clinically backed up by decades of research and double-blind studies, but it also has the power to alter the growth cycle of your hair to your advantage. Don’t forget that hair loss can also be costly!
Don’t forget to stay away from short treatment times, and to inquire about whether a laser hair therapy device is actually constructed with lasers, as opposed to Light-Emitting Diodes. The FDA-cleared Theradome LH80 PRO, for instance, is engineered with 80, individual laser diodes that radiate at a wavelength specifically developed for hair rejuvenation; remember that 635 nm and 655 nm lasers are used for CDs and DVDs and are thus manufactured in bulk overseas (and bulk = low quality!). Together these diodes output an ideal power density, that, with 20 minutes of continuous treatment time, ensure the base of your hair follicles absorb the energy they need to “live long and prosper”.
