contact with me to got best ideas of management to market

Because this is highly localized, and in the beauty industry it's common for people to ask for referrals from people they know/like/trust.. I would suggest trying to go after some local influencers. Reach on Instagram, send them a direct message - tell them you'll give them a free service and if they had a positive experience you'd appreciate them posting about it on their social media. Once folks start to see you do a great job and can see their friends/folks they follow have gone to you and they like the results, you'll start getting business organically.

My advice is to start having conversations to uncover the common complaints they have with their current supplier. Then determine if that can be solved by you.

Firstly it would be important to let your USP shine through, give them a reason to put your product in their spa’s. And secondly to market on platforms where you are most likely to find business owner, messaging spas in your local area, putting targeted ads on Instagram, building a following etc.

Hope this helped a bit, feel free to drop me a message to discuss this further.
