Theradome Evo Laser Hair Growth Device vs Kiierr 272 Laser Cap

Modern problems require modern solutions – and as far as hair restoration therapy is concerned, low-light laser therapy (LLLT) is one of the more modern approaches to defeating the problem of hair loss. But with a veritable wealth of laser devices available on the market, it can be difficult for someone – especially someone new to the LLLT scene – to choose a product that’s right for them. In this article, we’ll be comparing two of the more popular options for LLLT.

Both of these products are tailor-made for helping hair regrow, but which one you decide to get is up to you. To help you with your decision, we’ll discuss what each of them can do for you and help you make your choice.

How Does The Theradome EVO Laser Hair Growth Device Work?

Before we delve into the specifics of the Theradome EVO Laser, it’s important to understand how LLLT treatment works in the first place. 

LLLT was discovered by the Hungarian surgeon and physicist Endre Mester by accident in 1967. While attempting to recreate an experiment in the removal of tumors in mice, Mester discovered that the shaved mice quickly regrew their fur after he had used a ruby laser on them. The laser was later found to be defective, but the side effect intrigued Mester so much that he devoted time to researching it, thus paving the way for modern LLLT.

Theradome Lasers

LLLT works by bombarding the surface of your skin (specifically, your scalp) with low-power laser light source. These lasers are greatly weakened versions of the cutting lasers commonly seen today. By irradiating your skin with photons, your cells become energized and stimulated to produce new, healthier hair. This treatment method is renowned for being safe and non-invasive.

The Theradome EVO LH40 medical device package comes with the helmet itself, foam fitting pads, a protective bag, an AC adapter, a user’s manual, and a Getting Started card for first-time users. You can also purchase separate replacement batteries, carrying cases, and TheraWipes for cleaning your Theradome EVO Laser Hair Growth Device.

How to Use The Theradome Theradome EVO Laser Hair Growth Device

  1. Wash your scalp with medicated shampoo.
  2. Towel-dry your hair. Expose thinning areas by combing and parting your hair. Do not use any products like leave-in conditioners.
  3. Tap the power button to turn on the Theradome EVO Laser Hair Growth Device. Put the helmet on with the power switch to the back of the head. Avoid rigorous activities while the helmet is on.
  4. Pay attention to the built-in speaker as it will notify you of the treatment progress.
  5. Once the 20 minute treatment is over, remove the helmet and charge it again.

Note that Theradome EVO Laser Hair Growth Devices need to be charged before their initial use. The power button will flash green once the device is ready for use.

For best results, Theradome suggests using the helmet at least twice a week, with 12-24 hour gaps in between treatments. You can also use other new hair growth products after treating your hair with the Theradome helmet.

Theradome EVO Laser Hair Growth Device Side Effects

There have been no documented harmful side effects linked directly to the use of the Theradome EVO Laser Hair Growth Device. However, there are some things you should watch out for.

Some customers have commented that their head feels itchy after using any LLLT product. This is normal and is in fact expected. Due to the increased energy demand of your energized hair follicles, blood circulation in the area will increase, leading to your scalp becoming itchy.

Other users have complained of their hair falling out after LLLT product use. This occurrence isn’t limited to just LLLTs as all hair regrowth products tend to lengthen or kickstart the anagen phase of hair growth. The anagen phase, or initial phase, of hair growth is when new hair starts to grow. At the same time, hair follicles are encouraged to discard weaker hairs to make room for the incoming stronger and healthier crop of hair.

 Theradome EVO vs Theradome PRO

Theradome Evo vs Theradome Pro

It’s all in the numbers – while both of these Theradome products offer full scalp coverage, LLLT in the comfort of your own home and freedom of movement during use, the LH80 PRO has 80 lasers, while the Theradome Evo Laser Hair Growth Device only has 40. These numbers also apply to the cost, as the Theradome PRO is a full $300 more expensive than the Theradome Evo Laser Hair Growth Device.

Regarding treatment time, a single session with the LH80 PRO is equivalent to two sessions with the Theradome Evo Laser Hair Growth Device. Likewise, you can get the same positive results with an EVO LH40; you just need to increase the number of treatment sessions. Theradome recommends waiting 12-24 hours after each LLLT session before using their laser helmets.

Does The Theradome EVO Laser Hair Growth Device Work? 

The Theradome laser helmet does work, but it rewards patience and persistence. Most customers report noticeable hair growth within 3-6 months, with continued use leading to lush and voluminous hair. Using the Theradome Evo Laser Hair Growth Device is a discipline; however, you can’t skip treatments and must be religious in maintaining your treatment schedule. Theradome suggests taking your own before and after photos to see how much progress you’ve made.

The first three to four months are marked by reduced hair loss. After this phase, you can expect thicker, fuller hair as your hair follicles will have been sufficiently stimulated into growing healthier hair. From six months onwards, most customers will have new, healthier hair.

Check our review if you’re interested to see the difference between Illumiflow 272 vs. Kiierr 272.

How does the Kiierr 272 Laser Cap Work?

The Kierr 272 Laser Cap works similarly to other LLLT products: using low-level lasers to energize your hair follicles and scalp, the Kiierr encourages greater blood flow and circulation. This, in turn, gives your cells greater access to essential nutrients and building blocks for stronger hair. 

How To Use the Kiierr 272 Laser Cap

The Kiierr 272 Laser Cap must be fully charged when delivered to you. Kiierr recommends using the 272 Laser Cap every other day for the best results.

  1. Insert the helmet into the included ball cap module, or any ball cap you choose.
  2. Connect the USB to the power pack and the Kiierr Laser Cap Module.
  3. Press the power button to place the Kiierr 272 Laser Cap on your head. The device will automatically power down after 30 minutes.

Theradome Evo vs Kiierr 272 Laser Cap

While the Kiierr has many, many more laser diodes than the Theradome Evo, their lasers differ in wavelength – Kiierr uses 650nm lasers, but Theradome uses 680nm. There is little to no evidence on the efficacy of these lasers against each other, with most LLLT advocates saying there isn’t a difference.

The Theradome is the clear winner regarding treatment duration and length, with 20-minute treatment sessions every 12-24 hours compared to the Kiierr’s 30 minutes every other day. The Theradome is also much more affordable, at a price tag of $595, while the Kiierr is at $875 for the basic package and $955 for the full set.

On the other hand, Kiierr 272 Laser Cap’s portable design is one of its greatest features. Unlike bulky laser helmets, you can easily bring and use it even when you’re traveling.

The choice is up to you. If you’re always on the go, go for the Kiierr Laser Cap, but if you work from home and budget is an issue, then the Theradome Evo is the best choice!

Theradome PRO vs Kiierr 272 Laser Cap

As the Theradome PRO is very similar to the Theradome Evo, except for lasers, it’s more of the same thing. However, the price tags are much closer, with the Theradome PRO costing $895 more than Kiierr’s basic package.

Addressing The Root of Your Hair Loss

One common mistake many people make is believing that a hair regrowth product will provide a miraculous and instant recovery from hair loss or even more severe medical conditions like androgenetic alopecia. That’s not the case, as no matter which route you’re going with treatment, you need to find the root of your hair loss to solve that problem.

While LLLT is an effective way to treat male and female hair loss, it’s important to find out why you’re losing hair in the first place. Dietary deficiencies can lead to hair loss, particularly if you’re not taking in enough protein, fatty acids, and zinc. Natural male and female pattern baldness is caused by dihydrotestosterone (DHT) synthesis and is best fought with DHT blockers.

Foreign contaminants or too much waste buildup from dead skin or overproduction of natural human sebum can clog your hair follicles, impeding hair growth and leading to itchy, irritated scalps.

The good news is that you can do most of these hair loss treatments with each other. Topical oils, balms, shampoos, and creams can moisturize your hair, returning it to a healthier state. Medicines like minoxidil can help stimulate blood flow and is particularly good when used together with LLLT. Dietary supplements or being mindful of what you eat can patch up your nutritional deficiencies and help you get the hair growth you want.

FAQs about Theradome Evo Laser Hair Growth Device

Does Theradome offer a money-back guarantee?

Yes, Theradome offers a 6-month money-back guarantee on their products.

Does Theradome Evo Laser Hair Growth Device cause itching?

The increased blood flow to your scalp will most likely produce an itching sensation in your scalp. This is common and is in fact, to be expected.

Can I use Theradome Evo while doing other tasks?

Theradome advises against strenuous or rigorous activities during treatment, as the helmet may become dislodged.

Do laser caps work?

Several clinical studies have shown that helmet-type LLLT devices are effective in increasing hair density and hair thickness of patients suffering from androgenetic alopecia. The results include a notable increase in hair thickness and density. The results are encouraging, but more research is needed to confirm the efficacy of LLLT for other types of hair loss.

Theradome Evo vs. Kiierr Laser Cap: Verdict

In terms of cost efficiency, there’s not much that either the Theradome PRO or the Kiierr 272 Laser Cap offer that the Theradome EVO can’t match, with a bit of patience. A relatively low entry cost makes the Theradome EVO a great way to get into the world of LLLT. And the negligible differences between laser wavelength means that there’s no particular “better” laser.

The Theradome Evo Laser Hair Growth Device also offers full scalp coverage with more time––something that the PRO offers off the get-go for an additional $300. While the Theradome EVO is the clear winner here, ultimately, it’s up to you to get what you want – whether that’s the faster treatment the Theradome PRO offers or the Kiierr’s ability to be taken outside.

Other laser treatments worth checking are Capillus Laser Cap, IRestore, and HairMax PowerFlex Laser Cap 272.
