SHR Technology for Hair Removal

Explore how SHR hair removal machines deliver painless, effective treatments using advanced SHR laser technology.

Laser hair removal has been one of the most common esthetic treatments for decades, but it finally lit up in 2006 when masterminds here at Alma developed the SHR technology and changed the way laser hair removal is performed.

What is SHR Hair Removal?

Unlike previous light-based hair removal technologies that pulse the skin with a very strong light beam to destroy the hair follicle, while also causing pain, creating inconsistent coverage, and possibly even burns, the main idea behind SHR is that the energy delivered to the target area is accumulative. That means the entire treated area is gradually heated using lower energy with high repetition to achieve maximum results and optimal coverage, with virtually no pain at all

How Does SHR work?

Alma’s patented SHR technology delivers low-fluence and high-frequency laser energy, so that tissue heating is gradual and therefore safer, even for darker, melanin rich skin.
The epidermis is further protected by the applicators’ cooled tip.

The SHR process uses an “in-motion” technique, where the practitioner glides the laser applicator over the patients’ skin, distributing the laser energy uniformly over the treatment area for consistent coverage with superior results and reduced burn risk. The laser transforms into thermal energy, which in turn terminates hair growth by destroying surrounding stem cells.

Frequently asked questions

  • Light and fine hairs are often hard to treat using conventional laser hair removal technology as they contain less melanin, requiring higher levels of energy to remove – which is unsafe. With SHR, the operator can target these hairs, by safely delivering the laser energy required to treat them.

  • Yes – SHR has been approved to treat all skin tones – Fitzpatrick Skin Types I-VI – even tanned skin.

  • SHR Stack mode allows for a safe stationary mode of treatment for small areas, or areas that do not enable SHR In-motion mode.

  • : SHR technology can be used with all our applicators. The most popular applicator on our Soprano platform is the Trio applicator (2 or 4cm2) which comprises a blend of three optimal wavelengths for hair removal: 1064nm, 810nm and 755nm. Our single wavelength applicators and IPL applicators can also be used for SHR treatment.
