Kiierr Laser Cap Reviews: Effectiveness at an impressive price

About the Brand

The Kiierr laser hair growth cap is one of the numerous brands that belong to Low-Level Laser Therapy (LLLT). Kiier laser cap can be used to treat hair loss and is possibly the most effective laser cap to enter the marketplace in the last several years. With medical-grade laser diodes, this high-quality laser cap promotes thicker and more beautiful hair regrowth in 7 months.

Though with a small number of subjects, some studies suggest LLLT can halt or even reverse hair loss at its early stages. Although LLLT is typically believed to be much less effective than the mainstream treatments like minoxidil and finasteride, it warrants some examination. 

In this Kiierr Laser Cap review, we take an in-depth look into this cap to establish what customers can and cannot expect from it and provide detailed information about it. We will also include a number of the actual Kiierr reviews from the clients and experts.

What is a Kiierr Laser cap?

Kiierr’s Laser Hair Cap is a powerful low-level cutting edge laser tool for the remedy of androgenic alopecia (‘male’ pattern baldness). You would possibly get confused by this laser cap’s look because it looks as if a basketball cap; however, beneath this cap, laser diodes are present that carry out all of the features of stopping hair loss and keeping loss  to a minimum.

Scientific trials support Kiierr laser technology, and the FDA cleared it to treat hair loss and thinning hair. The Kiierr laser cap hair regrowth remedy is a new progressive alternative for people going through alopecia (hair loss based on genetics). Its technology is portable, and you can do new hair growth discreetly anywhere and anytime: at home, at work, in the car, walking errands.

The Laser Cap has two models. One has 148 laser diodes. The alternative has 272 laser diodes. They are the basically the same; the latter has larger laser diodes and higher coverage, but it is more expensive.

Unboxing Kiierr Laser Cap

The laser cap itself is made from an outer hard plastic shell that protects the internal laser panels containing the diodes. Beneath the cap and over the laser panel, you’ll see a transparent plastic cowl that keeps the laser diodes from touching your head directly.

Inside the Kiierr laser cap package, you’ll find the laser cap, portable power pack, consumer manual, comfort headband, and branded Kiierr baseball cap.

The included portable power pack is used to start treatment. Small blue light force packs make it easy to understand how much charge you have left. Kiierr states that a full charge should last 2 to 3 times  maximum of 30 minutes.

Low-Level Laser Therapy (LLLT)

Low-Level Laser Therapy (LLLT)  [1] is a common preference when laser remedies are required for medical problems such as promoting the healing of wounds, nerve regeneration, and alleviation for aching joints, recovery from stroke, and the treatment of mucositis, among many different applications  [2]. In recent years, studies have shown that LLLT can be used for neurological and mental illnesses. These diseases include depression, Alzheimer’s disease, dementia, Parkinson’s disease, stroke, and traumatic brain injury.

Low-level laser therapy also can considerably treat people who suffer from androgenetic alopecia  [3] or male/girl pattern baldness. Because LLLT uses lasers to enhance cellular respiration, it could stimulate the hair follicle cells. It also can regrow hair circulation and encourage hair follicles to produce hair growth through gentle stimulation.

It is believed that LLLT will increase blood flow within the scalp and also stimulate metabolism in telogen (resting) follicles, resulting in the assembly of anagen (growth) hair. Those strands that are within the resting period for too long can presently generate and regrow. 

Unlike cosmetic lasers, LLLT emits no heat, sound, or vibration. Instead of producing a thermal effect, LLLT acts through non-thermal (hence first given the name of cold laser) or photochemical reactions in the cells. That’s why Low Light Therapy is occasionally also referred to as photobiology or biostimulation. Low-level laser therapy caps, including Kiierr’s hair growth caps, use this technology to convey the best hair growth results.

Is the Kiierr laser cap safe?

Yes, if you buy an FDA-approved laser cap, including Kiierr laser cap, you can be sure that it is safe to use as per instructions for men and women over 18 years of age. There aren’t many side effects of these laser therapy caps as the FDA has approved them. You can even read the FDA document clearing the Kiierr Laser Cap for use before reading its reviews. As it says on the National Center for Biotechnology Information, “LLLT for hair growth in both woman and men seems to be safe and effective.

However, the individual must take some safety measurements to stay themselves from any possible hazards.

  • It is strictly prohibited to look directly at laser diodes because it may damage your eyes.
  • If you want a break in the course of your session, turn the tool off. .

Unlike taking medicinal drugs for hair loss, there are no known side effects to LLLT and laser caps.

Does It Work For Hair Growth? 

Kiierr laser caps are approved by the FDA and tested clinically to grow hair effectively again and on men’s and women’s scalp. Kiierr Laser Cap specifically has a 93% success  [4] rate in clinical studies[5] reviews.

One thing to keep in mind is that the effects do not occur overnight and can take time, so it is essential to be patient, we do not lose all our hair during the night, so it is vital that you use the device continuously for seven months. It is not uncommon for a few clients to observe the regrowth after only a few months of use.

“Using the Kiierr laser cap 8 months. The front of my hair looks great! I use the cap for 30 minutes every other day. I feel that my hair is in better condition too!”

Mary-Beth F.

I” LOVE THE KIIERR LASER CAP! Prior, I had a laser comb. It was cumbersome and time consuming (20 minutes of holding it everyday!). Now I do my “LASER Cap” while reading my devotions!!! Thank you for your great customer service too.”

Linda R.

” just completed three months of treatment. The attached before and 3 months after photos have both been taken in the same location with same lighting and same hair cut. It looks like there could be some improvement but not much. The shampoo and conditioner gives it a different look or maybe it is growth, don’t know. I am looking forward the next 4 months.”
