Hair Removal Device Review and Comparison

Hair Removal Device Review and Comparison

If you’ve been up late at night, you might have seen infomercials for the no!no! hair removal device. Its promise is to remove body hair with ease and deliver total satisfaction. In fact, it makes some rather impressive claims that could have a consumer thinking it’s the solution they’ve been waiting for.

But what if The Silk’n Infinity hair removal device offered treatments more suited to your lifestyle and hair removal goals? This state-of-the-art device is FDA approved and clinically proven to permanently reduce body and facial hair after completing a full treatment.

The debate over which at-home hair removal device is better has been raging for some time. The best way to decide is to perform a side-by-side comparison of price, technologies, treatment duration, results and user reviews.

Let’s start by creating a checklist of the features and benefits you should look for in a device. Next, we’ll take a deep dive into each of the no!no! and the Infinity to help you better understand how they work and reveal any shortcomings.

How to Review At-home Devices

Millions of people have flocked to at-home hair removal devices as an affordable alternative to professional laser hair removal treatments.

Here is a checklist you should use to weigh the value of each device. The one that checks the most boxes most likely will be the one for you. We recommend tailoring this list to your needs. For instance, if budget isn’t a concern than remove it from the list.

  • Is the device safe & FDA approved?
  • Does it fit my budget?
  • Do I understand how to use it?
  • Are user reviews generally positive?
  • Is the technology proven to work?
  • Is it better than my current method?
  • Can I commit to a regular treatment session?
  • Can I commit to a complete treatment plan?
  • Am I willing to commit to a post-treatment maintenance plan?
  • Is my skin tone and type susceptible to treatment?
  • Do I have any skin sensitivities that could hinder the device’s effectiveness?

You need to decide how important an unchecked box is to you. In some cases, it could tip the scales toward one device. 

Comparing Hair Removal Technologies

These home hair removal devices rely on different technologies to target and attack unwanted hair. On the surface, the technological difference can be boiled down to the no!no! using heat whereas the infinity uses a heat generated from light energy.

But it’s a bit more complicated than that.

The Infinity marries two modern technologies, Home Pulsed Light (HPL) and galvanic energy, to provide the most thorough treatment available on the at-home market. HPL safely and effectively emits a steady pulse of optical light energy directly into the skin. This light energy is attracted to and absorbed by pigment in the hair shaft. It is then transformed into heat, which kills the hair. The result is two-fold: the hair is removed and surrounding skin is unscathed.

The addition of galvanic energy makes the Infinity an improvement on existing Silk’n devices that were already considered best in class, and further separates it from the at-home pack. Galvanic energy produces professional results without pricy salon appointments. It works by emitting a low-level current that opens pores, allowing treatment to be administered deeper into skin, leaving the surface smooth and supple.

Make no mistake, it is galvanic energy and its ability to enlarge pores that propels the Infinity to the next level, creating a more potent treatment that won’t bend to the will of stubborn hair. This device will destroy unwanted body and facial hair that you believed would be present forever.

The no!no! uses a technology called Thermicon that leverages thermal transference. As a user moves the device across their skin, it releases a low heat that claims to remove stubble then travels down the follicle to remove the hair and prevent growth.  

Thermicon technology also promises to crystallize the follicle. This means it will cut off the follicle from its blood supply, resulting in the follicle dying. This has been debated as some users and testers believe it singes hair without crystallizing it.

One positive is that skin tone doesn’t dictate effectiveness, and it is safe to use on various hair colors. Procedures are pain-free, quick and don’t create a mess like hot wax or depilatory creams. Of course, being safe doesn’t mean much if it doesn’t work.

How Do Hair Removal Treatments Differ?

The Silk’n Infinity requires 8 treatments that breakdown as follows:

  • Treatments 1-4 should be performed two weeks apart.
  • Treatments 5-7 should be performed four weeks apart.
  • Treatments 8 and beyond are considered maintenance and should be performed until you are happy with the results.

Essentially, you’re signing up for a hair removal regimen that was developed based on the human hair growth cycle and takes at least two months. This would be the same approximate time frame as professional laser hair removal treatments.

Per the no!no! website, treatments can be conducted on any body part except the breasts and genitals.  As far as treatment duration, the no!no! states, “Hair does not grow in the same place at the same time, no!no! takes time and patience and will be different for each person.”

While this statement seems to have walked back from earlier claims about the product’s quick results, however they are correct to suggest that longer and/or coarser hair takes longer to remove regardless of method, and that everyone’s hair has different growth cycles so it’s true that it’s difficult to say how long any hair removal device will take to work.

This home hair removal device requires that you use it 2-3 times a week for the first few months. Once a full program is complete, it is recommended to start an ongoing maintenance regimen. Directions are unclear as to whether you need to begin treatment during a specific point of hair’s growth cycle.

At Home Hair Removal Cost Comparison
