Choosing a professional laser hair removal machine
Choosing a professional laser hair removal machine means comparing stated specifications, not marketing wording. This guide lists the points a salon buyer should check, in the order that matters most for a machine that will be used daily.

The guide is written for buyers, not for treatment advice. It does not recommend a wavelength, a spot size, or a machine for any individual client, and it makes no guarantee about results.
Specification points to compare
Start with the wavelength or wavelength set: 808nm diode, a mixed 755nm, 808nm, and 1064nm combination, or IPL bands such as 640nm to 1200nm. Then compare spot sizes, since spot size affects treatment speed and coverage, and cooling methods, since cooling affects client comfort and operator workflow.
Then compare handpieces and attachments: which handpieces are included, which are optional, and what each one is for. A machine with a single handpiece and a machine with several are not directly comparable on price alone, and buyers should list what is included before comparing prices.
Supplier points to confirm
Confirm the documentation supplied with the machine, including user manuals and any training videos. The manufacturer's DPL4-A2 product page lists documentation, video support, and online video support among its after-sales services; buyers should confirm which of those apply to the machine they order.
Before payment, confirm the model, the specification from the current product page, the quantity, the price, the delivery terms, and the after-sales arrangements in writing. Ask how faults are handled and what support is available after delivery, and get the answers in writing rather than relying on a sales conversation.
