Hi Laura,
Welcome to the new Forum! Great question, by the way. I think Lynn H.'s experience was positive because of how she approached the opportunity. Very smart. Unfortunately, many estheticians report disappointment with the missing support they thought they'd get from the hairdressers and nail techs that work in the salon they're employed by or rent at. Seems that there's some initial enthusiasm for referrals and then, soon after, nothing. Here's the best strategy I know of to inspire co-workers to keep your services at the forefront of their conversation with clients:
1. Like Lynn H. you'll certainly want to sample your services to prospective referral partners. The mistake that many estheticians make when doing this is in not effectively educating your partner in the benefits of the treatment or teaching them how to promote it to customers. Often times the two techs just chat in the treatment room about the salon, customers and all sorts of personal stuff while the facial is being performed. Your partner will be grateful for the nice feeling experience but quickly forget about it. You esthetician then becomes resentful for having given a treatment away for nothing. Not good news. Treat your referring partner
exactly as you would a new client with all of the courtesies and customer service they deserve. This is what customers experience so demonstrate the real thing. Far more productive than discussing the mean front desk lady they hired.
2. Make yourself known! Yes, I know we're all a little shy but unknown and unseen people remain, well, just that! The shy, regretably, are often mistaken for being aloof or snobbish when thay are, in fact, just the opposite. In my first esthetics job which happened to be at a hair salon, I'd hang around the cutting area and (having asked permission to do so) would introduce myself to customers being served at the hair stations. I'd offer every client a free skin analysis or makeup session. Not every client took the offer but many did. Much better than waiting for that phone to bring them in!
3. Be hard to dislike (also known as kissing some butt...) by doing small favors for key people in the salon. It's hard to forget or dislike someone that's really nice to you.

Does the front desk employee like a midday cappucino? Get her one as a special surprise now and then while telling her how hard you know that she works. Praise her (try to be authentic, don't grovel) for her great work. Want to be the one she assigns the new facial clients to even though you're the last one hired? This will do it!
4. I used to do a skin analysis right at the makeup bar of one salon I worked for. Had a special scope/camera that worked off of a portable television so I could show customers what was happening with their skin without having to take back into the treatment room. Then, I'd recommend products or treatments to improve the massively magnified flaws. You can even do this while a client is waiting for their always-late hairdresser to come for them. Why, you may have an hour or more available to do it in!
Well, this worked for me and I think it will for all of you, too.
My best,
Douglas Preston
