Wellaholic Research: Comparing SHR Laser Hair Removal with Alexandrite Laser Hair Removal

In my years at Wellaholic and before, I’ve seen many hair removal technologies. One topic that often comes up is the difference between Diode Laser with SHR and Alexandrite Laser. I’ve talked to many clients and experts about this. I’ve also looked into research to understand it better.

Diode Laser with SHR is a newer method. It’s gentle and works for different skin types. Alexandrite Laser is powerful and fast. It’s great for lighter skin. Each has its benefits depending on your needs.

In the next part, I’ll share more details on this. I’ll talk about how each method works, who it’s best for, and what to expect. This will help you choose the right option for you.

Background of this Research and Study

In this 2016 comparative study by S. Hammes, H.M. Ockenfels, H. R. Metelmann, C. Raulin and S. Karsai, (in German), a controlled study with 18 patients was conducted to compare the effect of laser hair removal between the long-pulsed alexandrite laser and the long-pulsed diode laser in SHR (or Super Hair Removal) mode.

The study found that SHR hair removal is effective for all skin types, and particularly effective for dark skin types with less or no pain for patients.

Background of Research

Photoepilation is a key use of laser therapy in dermatology. It removes unwanted hair using light. This method effectively reduces hair growth, providing a long-term solution for people who want to stop using temporary hair removal methods.

Recently, there has been interest in evaluating the effectiveness of a new operation mode of a long-pulsed diode laser for photoepilation. The new approach aims to make treatment easier, less painful, and with fewer side effects. It is effective for all skin types.

To evaluate the benefits of this new laser operation mode, it has been compared to an established method of hair removal using light. The goal of this comparison is to see if the new approach can provide similar or better results in reducing hair, while also enhancing the patient’s overall treatment experience.

The evaluation aims to improve photoepilation by introducing a more effective and comfortable treatment method. If successful, this could revolutionize the way individuals approach hair removal, making it a more pleasant and hassle-free experience.

Photoepilation has been an essential field of application of dermatologic laser therapy for many years.

Material and methods

A careful study was done. 18 people were chosen to participate. There were 12 women and 6 men. These individuals ranged in age from 22 to 58 years, representing a broad spectrum of adults. The study was designed to compare the effects of two different types of photoepilation methods.

The first method utilized a long-pulsed alexandrite laser, a well-established tool in the field of photoepilation. The second method involved the use of a long-pulsed diode laser, but with a twist. This laser was operated in what is known as the Super Hair Removal mode, or SHR for short.

The goal of the study was to directly compare these two methods in a real-world setting, with actual patients. The researchers wanted to learn which method is better for photoepilation: laser or intense pulsed light. This study’s findings could greatly impact dermatologic laser therapy, making hair removal treatments more effective and comfortable for patients.

The study found that the alexandrite laser and the Super Hair Removal (SHR) mode of the long-pulsed diode laser each have their unique advantages, depending on the skin type and the user’s comfort.

The alexandrite laser showed slightly higher effectiveness when used on fair skin types. This could be due to the laser’s specific wavelength, which may be more readily absorbed by the hair follicles in lighter skin, leading to more effective hair reduction.

Result of Study

The study found that both the alexandrite laser and the long-pulsed diode laser in Super Hair Removal (SHR) mode have different advantages. These benefits vary depending on the user’s comfort level and the type of skin.

The alexandrite laser showed slightly higher effectiveness when used on fair skin types. This may be because the laser’s wavelength is more easily absorbed by the hair follicles in lighter skin, making hair reduction more effective.

On the other hand, the SHR mode was found to be clearly more effective with dark skin types. The SHR mode is better for darker skin types because it delivers lower energy levels over more pulses, which is preferable for skin that absorbs more light energy.

In terms of comfort during the procedure, the SHR mode was deemed clearly superior. SHR mode is more comfortable because it uses lower energy levels delivered at a faster repetition rate.

When it comes to the speed of the treatment, both systems were found to be comparable. This suggests that both methods can deliver efficient treatments within a similar timeframe.

However, in terms of user-friendliness, the alexandrite laser was favoured due to its light and small handpiece. This could make the device easier to handle and manoeuvre during treatments, potentially leading to a more seamless treatment process.

SHR mode is clearly more effective with dark skin types. Regarding painfulness, the SHR mode is clearly superior


The major advantages of the SHR mode are its effectiveness in dark skin types and its lack of pain. The alexandrite laser is slightly more effective with fair skin types, slightly faster and its handling is considerably more comfortable. None of the two systems has yet brought about a breakthrough with fair hair.
