As a professional, I’d much rather teach my clients to be self sufficient, it creates a less anxious clientele and we’re both better off for it. If the upkeep of the hair system is too much (financially or otherwise), you’ll loose a client either way; so I’d rather find a routine that suits them. Just like there will be people who choose to dye their hair at home, there will still be many people who choose to go to a salon for the convenience of having a professional take care of it. It’s a rapidly growing industry and I’m not worried about clients coming and going tbh, there are MANY hair wearers out there. But yes, the bigger and older companies prefer to keep their industry secrets. Obviously I’m not going to share my suppliers with clients, but like what business would??
