How can I avoid frizz after hair straightening?

To prevent frizz after hair straightening, follow these steps:

1. Start with clean, well-conditioned hair to ensure a smooth foundation.
2. Use a heat protectant spray before straightening to shield your hair from damage and lock in moisture.
3. Work with small sections while straightening, using a high-quality flat iron with adjustable heat settings.
4. Avoid going over the same section repeatedly to prevent overexposure to heat.
5. Once done, apply a lightweight hair serum or oil to seal the cuticle and add shine.
6. Use a silk or satin pillowcase to reduce friction and maintain your style overnight.

Remember, proper care and maintenance are key to achieving and preserving a sleek, frizz-free look after straightening your hair.
