Considering a chemical relaxer during GLP-1 treatment? Review these questions before your appointment.
1. Who will apply the relaxer?
For Black hair, the American Academy of Dermatology (AAD) recommends a professional stylist to help minimize relaxer damage. [1]
2. Which hair needs a touch-up?
AAD advises touch-ups only every two to three months, applying relaxer to new growth rather than previously relaxed hair. Ask the stylist to review your last application. [1]
3. Is color booked too close?
AAD recommends one chemical service at a time. If combining services, its guidance places a perm or relaxer two weeks before hair coloring. [2]
4. How will timing be checked?
FDA advises following the package directions, wearing gloves, leaving the product on no longer than instructed and rinsing the scalp thoroughly afterward. [3]
5. What if I have a reaction?
FDA advises stopping the product and calling your healthcare provider after a bad reaction. It lists itchy or raw skin, scabs and hair loss among problems to report. [3]
