Call your local Cancer center or the National Breast Cancer Foundation and they will send you a ton of marketing materials like self exam postcards, pink ribbon reminders and more literature than you could imagine. They are more than willing to send as much as they can for free to help support your event. Make sure to get postcards in the mail, put an event up on Facebook or in Eventbrite even on Yelp and twitter. Remember on social media especially twitter to send this out several times a week to make sure you get as much exposure as you can.
Partner with a local med center or cancer center. Ask to speak with the office manager and offer a certain percentage off any service for every woman that gets a mammogram in October, or put together a free gift like a sample hand cream, mini pink polish, pink emery board and sample nail oil. Have the literature up on mirrors, in the bathroom, at the front desk and at your nail table to spread the word and encourage women to get this often times life saving procedure. Offer a free gift or free upgrade to any client that gets a mammogram in October. Offer a contest in your salon for a pamper day to a breast cancer survivor. Encourage your clients to nominate a survivor by sending their story in by email or snail mail. The year we did this we were so touched by the many stories of amazing bravery and courage that we ended up sending each one a $15.00 gift card. They were so appreciative and our client who nominated them was so proud to share this opportunity including bragging rights that her salon values the health and well being of women in the community and isn't holding back but giving back. The good will generated by an all out Breast Cancer month is priceless. Make sure you are writing press releases about your specials and events and invite the local news anchors to your salon to experience it firsthand.
