The Max Pro Gloss Black lives up to its name. Thanks to the fully ceramic plates, adjustable temperature, and ionic function, this hair straightener lets you turn any hair type into a glossy coupe. You can set the temperature between 80 and 230 degrees. For dyed and fragile hair, you should set the temperature below 180 degrees, while thicker hair requires a temperature between 200 and 230 degrees. This hair straightener can also make curls. The edges of the plates are rounded, and the plates move along during the straightening process to prevent any angles from forming in the curl. The result is a glossy curl or a straight hairdo that's not static, thanks to the ionic function.
