What is Kiierr Laser Cap?

As the name suggests, it is a laser cap that is designed to treat hair loss conditions, including androgenic alopecia, receding hairlines, hair thinning, and early stages of baldness. The Kiierr Laser Hair Cap makes use of cutting-edge laser technology that helps strengthen existing hair.

With its design similar to a basketball cap, the cap carries laser diodes that are effective in preventing hair loss. This device utilizes diodes with 650nm wavelengths to stimulate hair growth cells and force them to regenerate. 

Two models of Laser Cap are available. One of them contains 148 laser diodes. Another has 272 laser diodes. In general, they are the same, except that the latter has larger laser diodes and more coverage at a higher price.

A number of scientific trials have supported Kiierr laser technology, and the FDA has approved it as a treatment for hair loss and thinning hair. The system is portable, so you can use it wherever you are, at any time: at home, at work, in your car, and running errands.

KIIERR is at the forefront of hair growth laser development and application. Kiierr was founded by Mike Anderson and Jolene Anderson in 2018. The technology they use in the cap is low-level laser therapy (LLLT), which is an innovative and revolutionary technology. 

Read the next section to learn more about LLLT.  

What is Low-Level Laser Therapy (LLLT)

Low-level laser therapy is unique in that it emits no heat, vibration, or sound. Photochemical reactions in the cells produce the thermal effect. This is why Low Light Therapy is sometimes called photobiology or biostimulation

LLLT is used for the treatment of wound healing, relieving joint pain, regenerating nerves, and treating mucositis. LLLT has also proven effective in treating mental and neurological disorders in several clinical studies, including dementia, stroke, and depression, to name a few.  

People with androgenetic alopecia or male pattern baldness can also benefit from low-level laser therapy. Laser LLLT stimulates hair follicle cells by enhancing cellular respiration. In addition, gentle stimulation of the cells promotes hair growth and regrows hair circulation.

As the blood flow within the scalp increases, it stimulates metabolism in follicles, leading to new hair growth. These hair follicles can now regrow into healthy and strong hair stands.

How does Kiierr Laser Cap work?

A Kiierr Laser Cap is a non-invasive treatment in which a few laser medical-grade laser diodes are directed directly to your scalp at low power. 

Due to its low power and wavelength, it’s entirely different from conventional laser therapy. This promotes collagen production and ensures that skin cells respire properly.

Here is how this laser cap works:

Stimulates Your Skin Tissue

A healthy scalp requires a plentiful supply of nutrients and oxygen. However, blood circulation is not always getting to these tissues the way it should. As a result of this lack of blood supply, the scalp swells, resulting in hair loss.

The LLLT technology promotes blood circulation in the scalp tissues. It helps damaged cells regenerate by providing oxygen and nutrients. The regeneration of cells also reduces the thinning of hair.

Enhances Cell Absorption & Protein Synthesis

Hair synthesis and growth require proteins, which are provided by the scalp cells. The scalp cells become weaker as they age, which affects protein production. 

The light from Kiierr Laser Cap can penetrate into the skin and help revive these weak cells. By revitalizing the scalp, the laser energy boosts hair growth.  

Regenerates Hair Follicle Cells

Healthier hair follicles determine healthy hair growth. But lack of nutrients and oxygen supply makes these cells go into an inactive phase where hair growth is stalled. Energy from the laser cap revives these hair follicle cells and stimulates the hair growth cycle
