Go to www.glossgenius.com (Sola users: sola.glossgenius.com) and click the Sign Up link in the top corner.
There, you'll want to enter in your email, choose a unique and secure password (if you have trouble remembering big, secure passwords, check out LastPass or 1Password!), enter in your contact information, then press "Sign Up."
Make sure that you're putting in that information in the right fields! Sometimes the "autofill" on a browser can accidentally put your email address into the 'First Name' field.
Finally, get Gloss! Head over to the Apple App Store (iOS) or Google Play Store (Android), download the GlossGenius app, and enter in your new login credentials that you used for signing up! (Don't worry, we'll text you a link to get the app right after you enter your contact details above.)
