Unwanted hair is a common problem that can be a source of frustration and self-consciousness. In recent years, the demand for a more permanent solution (aka laser hair removal) has sky-rocketed. However, not all laser hair removal technologies are created equal, and not all are suitable for all skin types. In this blog, we’ll explore the differences between laser hair removal technologies and why choosing the right one is crucial for achieving the best result.
When it comes to laser hair removal technologies, there are many options. The five most common types of hair removal laser systems include the Ruby, Alexandrite, IPL, Diode, and Nd:YAG.
To understand each technology better, it is important to be aware of the 4 laser parameters that play a significant role in the effectiveness of treatment:
- Wavelength
- Pulse Width
- Spot size
- Fluence
Ruby Laser (Skin Type I-III)
The ruby hair removal laser was the first system developed for permanent hair reduction and not well-known in South Africa. This system uses a shorter wavelength of 694nm that targets melanin. This makes the ruby laser more effective for lighter skin types with dark hair and is not recommended for individuals with darker skin tones.
Alexandrite Laser (Skin Type I-III)
The alexandrite laser is a popular option amongst aesthetic clinics and delivers great penetration for good results. Alexandrite may not be the most comfortable technology for patients, but latest equipment have built-in cooling devices to improve patient experience and to minimise discomfort. The alexandrite laser operates at a shorter wavelength of 755nm, making it ideal for targeting melanin in the hair follicles of individuals with light to olive skin tones.
Diode Laser (Skin Type I-V)
Diode equipment’s energy source consists of semiconductors, known as diodes, grouped together to create a laser beam with a wavelength of 800-810nm. This is a longer wavelength, better for penetrating deep into the hair follicle. This makes the diode hair removal laser system popular among men seeking treatment to remove back hair or chest hair.
Nd:YAG Laser (Skin Type I-IV)
Nd:YAG systems provide the latest advancements in aesthetic laser technology. Besides effective hair removal lasers, this system offers numerous applications including tattoo removal andlaser skin resurfacing for the correction of sun damage. Nd:YAG systems operate at a wavelength of 1064nm and is safe for all skin types.
IPL
IPL laser hair removal does not utilise a true laser, but the equivalent in the form of intense pulsed light (IPL) like lasers, IPL’s initiate photothermolysis by pulsing thermal energy that is absorbed by melanin in the hair follicle. The advantage of intense pulsed light is a customisable wavelength,energy level, and pulse duration. However, higher risk for epidermal damage and less effective than other lasers.
Still unsure which technology to opt for. The below graph & illustration best explains the effectiveness of each technology.
Now that you understand each technology, I know what you are thinking: “Why can’t we combine all the technologies together to get the best of all them all?”
Well, maybe not all of the technologies, but have you heard of a dual wavelength device? The gold standard in laser hair removal and our technology of choice is alexandrite combined with Nd:YAG.
Next time you book a laser hair removal session, check what technology the clinic utilises to ensure maximum results.
Our device of choice: Clarity II by Lutronic
P.S. One last very important variable to remember is that a high quality laser must be accompanied by a skilled operator for superior results.

FAQs
The five most common types of hair removal laser systems include the Ruby, Alexandrite, IPL, Diode, and Nd:YAG.
What are the different types of laser hair removal technology? ›
The five most comon types of hair removal laser systems include the Ruby, Alexandrite, IPL, Diode, and Nd:YAG. Each laser system is different from the other. Some lasers are better for certain types of hair. Some lasers are safer for individuals with darker skin tones.
What is the most effective laser hair removal technology? ›
When it comes to efficacy, alexandrite lasers beat all of the other laser technologies. Studies consistently show that alexandrite laser devices can eliminate a greater percentage of hairs compared to other machines.
What is the difference between IPL and SHR? ›
The main difference between SHR and IPL is the type of light used to target the hair follicles. IPL uses a broad spectrum of light, while SHR uses a combination of wavelengths that work together to provide more effective hair removal results.
What laser hair removal do the Kardashians use? ›
The Kardashian-Approved Laser Treatments
Kim often does her treatments late at night and is believed to use at-home laser devices. Khloe and Kylie, on the other hand, visit Sev Laser for Candela GentleMax Pro treatments.
What is the newest type of laser hair removal? ›
Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) laser is the most recent laser hair removal technology and is considered the gold standard for treating individuals with darker skin tones.
Which is better diode or Alexandrite laser hair removal? ›
Diode lasers are typically more effective for individuals with darker hair and fair skin, while alexandrite lasers are more versatile and can be used on a wider range of skin types and hair colors. Another factor to consider is the treatment area.
What is the new technology for hair removal? ›
IPL refers to a form of permanent hair removal with pure light. The abbreviation stands for “Intense Pulsed Light”. The light is guided by varying wavelengths to the depth of the hair root, where it scorches them. As a result, the hair falls out within three to twenty days and does regrow afterwards.
Which type of laser has highest efficiency? ›
Diode Laser
Only in Diode lasers, where electrical energy is directly transformed into laser radiation, it is possible to achieve high efficiency. Such high efficiency is the reason why not much energy is wasted in Diode lasers, and they can operate without special cooling mechanisms.
Which is better, shr or diode laser? ›
The study compared the effects of two types of laser hair removal: long-pulsed alexandrite laser and long-pulsed diode laser in SHR (Super Hair Removal) mode. The study showed that SHR hair removal is effective for all skin types and particularly effective for dark skin with less or no pain for patients.
There is a wide array of different types of lasers and all have different frequencies. In a traditional LHR treatment, the high-powered laser is beamed at each hair follicle. With the Alma SHR device, instead of a single beam at high power, the device repeatedly beams at lower power and in a sweeping motion.
What is IPL vs DPL vs SHR? ›
IPL cannot be used for dark skins, red, white and grey coloured hairs. That is the only advantage of DPL which treats all types of hairs. DPL has the ability to clean the pores and tightens the skin if it is aged. SHR uses tender pulses of energy at a relatively higher repeated rate.
How do the Kardashians stay hairless? ›
There are two treatments that Kim Kardashian (the most famous Kardashian of the bunch) has admitted to getting: Botox and laser hair removal. That's right. We may not have access to everything Kim Kardashian does to achieve her look, but we certainly have access to laser hair removal.
Does Kim Kardashian regret laser hair removal? ›
With Kimberly being more than open about her regret of using laser hair removal to tidy up her hairline and zap away her baby hairs, you'd be forgiven if, like me, you assumed she woke up with a full and thick mane every day.
What lasers do celebrities use? ›
ForeverYoung BBL: The Secret to Ageless Skin

Which is better, IPL or diode? ›
IPL laser hair removal will most likely require more than one session, while using a diode laser may work more effectively. Diode laser hair removal is more comfortable because of the integrated cooling and treats more hair and skin types, whereas IPL is best suited for those with darker hair and lighter skin.
What is the difference between diode and Nd:YAG laser hair removal? ›
However, Diode lasers can also provide excellent results for those with slightly lighter or medium-dark skin. In conclusion, both ND Yag and Diode lasers offer effective solutions for hair removal, but ND Yag lasers are often the safer and more effective choice for dark skin tones.
Is IPL better than laser? ›
Both IPL and lasers are effective in hair removal. IPL often requires more treatments and may not achieve the same final hair reduction as a laser can. Due to this, hair removal using a laser usually produces faster results. IPL is effective in not only hair removal, but also treating rosacea and facial flushing.
Is electrolysis or laser better? ›
Electrolysis is considered a more permanent solution than laser hair removal (it stops hair growth completely while laser hair removal slows and reduces hair growth), but it requires more individual sessions (closer to 14), and the sessions can take longer. You might not see full results for nearly 18 months.
