Can you use a relaxer on your hair while you have a keratin treatment?

It is not recommended to use a relaxer on your hair while you have a keratin treatment. Combining these two processes can lead to excessive damage, as both treatments alter the hair’s structure. If you're considering a relaxer, it’s best to wait until the keratin treatment has fully grown out or washed out, typically after a few months. Always consult with a professional stylist for personalized advice.
