How Does A Kiierr Laser Cap Work?
A company called Kiierr is dedicated to treating hair loss. The laser cap, a gadget worn on the head, is its main weapon in this combat. It has several laser diodes that are adjusted to a particular frequency and wavelength. Low-level laser therapy, or LLLT, is the term for the therapeutic approach.
Additionally, Kiierr offers a small range of hair care products that mix topical remedies with vitamins, minerals, and botanicals that are effective in research on hair loss. Many users discover that using these auxiliary therapies in addition to LLLT improves the caliber of their outcomes.
What is LLLT?
Low-power lasers are used in low-level laser therapy (LLLT), often referred to as photobiomodulation, to induce cellular changes that promote tissue repair and lower inflammation. Because they don’t generate a lot of heat, LLLT diodes are seen as non-invasive alternatives to surgical or high-power lasers.
Although the precise mode of action of LLLT is not well known, increased blood flow to the scalp is probably the result of laser exposure. The added blood would enhance the follicles by supplying them with more nutrients and oxygen. Additionally, there is proof that LLLT can reset growth phases, which will enable your follicles to begin a new growth cycle with the improved delivery of nutrients and oxygen, promoting the growth of new hair strands. Scientists believe that minoxidil therapies work through a similar mode of action. Similar to minoxidil, this mechanism might also entail the activation of genetic signal pathways associated with hair follicles and hair growth phases.
With LLLT, a specified area of the body is exposed to concentrated light emissions that have been tailored to a certain frequency and wavelength. The red light emitted by the laser caps has a wavelength of about 655 nanometers, derived from 5 mW laser diodes. Numerous studies have shown that this is one of the most efficient wavelengths for treating hair loss.

148 Pro Laser Cap

The 148 Pro Laser Cap is the entry-level model in the Kiierr range. It features 148 medical-grade laser diodes that emit red light at a wavelength of 650nm. This cap is designed to be worn for 30 minutes every other day, and it provides full coverage to the scalp area.
272 Premier Laser Cap

The next level up in the Kiierr line is the 272 Premier Laser Cap. It has 272 red light-emitting medical-grade laser diodes with a 650nm wavelength. Because it features more laser diodes than the 148 Pro, this cap provides greater coverage. Every other day, it is worn for 30 minutes as well.
272 MD Laser Cap

The 272 MD Laser Cap is a more advanced model that is recommended for individuals with more severe hair loss or those who have not seen significant results with the previous models.

Who Is A Kiierr Laser Cap For?
For those considering laser hair loss treatments but unable to afford to spend $3,000 on the equipment, Kiierr is a great choice. Furthermore, LLLT is a fantastic alternative for anyone who would prefer to avoid taking medications with possible negative effects or who has tried finasteride and minoxidil without success. Some of the scariest adverse effects associated with finasteride include increased sadness, decreased libido and sperm count, and, in certain situations, erectile dysfunction.
Having said that, you could wish to combine minoxidil with LLLT if you’ve used it with any success. Research indicates that the combined use of minoxidil and LLLT leads to a large compounding effect. More hair may regrow as a result in less time.
