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.
