Im seriously thinking of booking myself on the hd brow training course but its a lot of money. I'll be doing this at home mainly in my beauty room but would also be offering it at the salon i work at. Can anyone whos trained in hd brows tell me pro's and con's of investing in this service. If anyone can suggest any other brand I'd appreciate that too. Im hoping by doing this i can upsell a standard eyebrow shape n tint and gain better reputation by offering the latest brands.
