“Does laser hair therapy cause shedding?” This is yet another rumor and unfounded myth surrounding laser hair restoration therapy.
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. This means it is NOT some type of gizmo manufactured in China, such as caps, combs, bands and LED devices. None of these are effective at repairing 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 the hair shaft diameter are three well proven 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.
Understanding the Hair Growth Cycle
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. This scientific term for this resting phase, a.k.a.– the Hair Graveyard, is the telogen phase.
Normally, every hair in the telogen resting phase is replaced by fresh, new hair ready to take its place. Healthy hair usually stays in the anagen growth phase from two to six years.
If you’re suffering from hair loss, whether for medical reasons, medications that cause extreme shedding, or genetics, that’s not the case. The anagen phase lasts for less than two years, and often hairs in the telogen phase are not replaced.
That’s why you begin to shed more and more, and eventually develop the dreaded female or male-pattern baldness.
How Laser Hair Therapy Improves Your Hair Growth Cycle
An optimal laser hair therapy device does a few things to support your 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 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. This means that their pace increases. So 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 speeds up the transitional and resting phases so that new hair can grow in sooner.
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.
Where the Shedding Myth Comes From
This is where the pesky shedding myth comes from. Dead hairs (which are already dead, to state the obvious) are cast away quickly, but only to make room for healthy hairs. So yes, you may notice a bit more hair falling out when you first begin laser hair therapy. However, these hairs are in telogen resting phase.
You certainly don’t want these on your head! And their departure works in your favor as it paves the way for the birth of fresh anagen hairs.
Still not convinced? While you can’t differentiate between anagen and telogen hairs with the naked eye, scientists and dermatologists can. Visualization techniques, such as microscopic analysis, as well as biopsies, will show that an anagen hair has a longer shaft, a sebaceous gland, and a hair bulb at the base of the hair.
A telogen hair has a much shorter shaft, no hair bulb, and 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! Low-level laser therapy 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.
What to Know About Laser Hair Therapy
This is also why laser hair therapy, is such a powerful tool at fighting hair loss. It has zero side effects that decades of clinical research and double-blind studies have backed up. Plus, 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 make sure your laser hair therapy device uses actual lasers, as opposed to Light-Emitting Diodes. The FDA-cleared Theradome PRO LH80 and Theradome EVO LH40, for instance, are engineered with 80 (for the PRO) and 40 (for the EVO), individual laser diodes that radiate at a wavelength specifically developed for hair rejuvenation. Remember that 635 nm and 655 nm lasers are made for CDs and DVDs and do not affect hair growth.
Together these diodes output an ideal power density. With just 20 minutes of continuous treatment time, the base of your hair follicles absorb the energy they need to “live long and prosper.”
