Millions of men and women suffer from hair loss on a regular basis. And, in many cases, it totally strips them of their joy and confidence. But with so many different medications and procedures for fighting hair loss, there’s one technology that seems to slip through the cracks. We’re talking about low level laser therapy, or LLLT.
Understanding Hair Loss
Losing your hair can feel like you’re losing a part of yourself. It’s not just about your looks – it’s about how you feel when you step out the door each day.

For some of us, it’s a few hairs in the sink. For others, it’s noticing their scalp more than they used to. Somehow, while it’s all technically the same, we each experience hair loss in a very unique and different way.
Hair loss can happen for all sorts of reasons. It might be genetics (thanks, Mom and Dad), stress, or even medical conditions. But regardless of the underlying cause, the search for an effective solution can be frustrating. (And it usually involves a lot of trial and error.)
When hair loss occurs, several things happen:
- Normal Hair Growth Cycle: Hair goes through a growth cycle that includes three phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). Normally, most of your hair is in the anagen phase, where it grows actively.
- Disruption of the Cycle: In hair loss, this cycle gets disrupted. The anagen phase shortens, leading to the premature entry of hair into the telogen phase. This means more hair is resting than growing.
- Shedding: During the telogen phase, hair strands are released and fall out. With hair loss, more strands enter this phase, leading to noticeable shedding and thinning.
As hair thins, more of the scalp becomes visible. This change is often more noticeable in certain areas, like the crown or hairline.
You might be the kind of person who has ignored hair loss up until now – turning a blind eye in hopes that it’ll just stop. Or you may be the kind of person who has tried all sorts of things, but nothing really seems to stick. This is where LLLT comes into play. Because while there’s no perfect solution, this technology is quickly emerging as one of the most effective long-term solutions for people who want to stop hair loss in its tracks and regrow hair.
What is LLLT?
Low level laser therapy (LLLT) isn’t exactly a brand new technology – it’s been around for years. However, up until a few years ago, it was limited to use in clinical settings. Now that it can be used at home with cost-effective devices, people are waking up to how effective it is.
According to Kiierr, a leading providers of laser caps for hair loss, the scientific concept behind Low-Level Laser Therapy (LLLT) is that the light emitted from the laser stimulates hair growth and reduces hair loss. The application of low-power lasers is said to enhance cell function through a process called photobiomodulation. During this process, laser light is absorbed by cells, stimulating their metabolism and protein synthesis. In essence, LLLT harnesses the power of light to promote healthier hair and combat hair loss.
LLLT uses laser light that’s below a specific energy threshold, but still within a very specific wavelength in order to safely stimulate skin tissue. This causes the re-entrance of hair follicles into the anagen phase of the hair growth cycle that we discussed above.
Laser Caps for Hair Loss
There are several different ways in which LLLT can be administered for hair loss, but laser caps have become the most popular option. This is largely due to their convenience and non-invasive use.
Think of a baseball cap, but with a high-tech twist. Inside these caps are low-level lasers that work on your scalp. And unlike traditional treatments, the caps are designed for regular, at-home use.
Laser caps are totally wire-free and hands-free. This means you can wear one while you’re cooking dinner, working at your desk, watching TV, or doing almost anything else. And they don’t require a ton of your time either. Kiierr, for example, recommends using it for 30 minutes every other day.
Fight Back Against Hair Loss
There are plenty of different strategies you can take to fight hair loss – including medication and surgery. But if you’re looking for a safe, painless, and natural way to deal with your hair loss, LLLT might just be the solution you’ve been searching for. It’s worth a try!
