Do I Have to Flat Iron My Hair After Keratin Treatment?

Understanding Post-Keratin Flat Ironing

After receiving a keratin treatment, it’s crucial to follow specific aftercare steps to preserve the sleek, frizz-free look. One commonly asked question is whether it’s necessary to flat iron the hair post-treatment. Here's everything you need to know.

What to Do in the First 72 Hours

According to The Smooth Bar, the first 72 hours after your keratin treatment are critical. Avoid washing your hair, using hair ties, or applying any products. This period allows the keratin to fully bond with your hair cuticles.

Is Flat Ironing Required?

While a flat iron is used during the keratin application process to seal the treatment, you typically don’t need to flat iron your hair again unless:

• You notice creases from sleeping
• Your hair gets accidentally wet before 72 hours
• There are minor waves or bends

If needed, gently use a flat iron to smooth the sections. Always use a moderate temperature setting and a heat protectant.

Expert tips from Keramane recommend keeping the heat around 300–350°F and applying a quality heat protectant spray beforehand.

Long-Term Hair Care Tips

To maximize the benefits of your keratin treatment:

• Use sulfate-free and sodium chloride-free shampoos – check Sunday Salon’s guide
• Avoid excessive heat styling
• Limit products containing alcohol or drying agents

Proper maintenance can extend your keratin treatment’s effects up to 3–5 months, depending on your hair type and care routine.
