Consuming a balanced diet that includes a variety of these foods can help support the body's natural keratin production. **

The choice between keratin smoothing and flat ironing depends on your hair type and desired results. Keratin smoothing treatments can help reduce frizz and make hair more manageable, but they are a longer-term commitment and can be expensive. Flat ironing, on the other hand, is a quicker and more temporary solution for achieving straight and smooth hair. It's important to consider the potential damage that frequent flat ironing can cause to your hair, so it's best to use heat protectant products and not flat iron too often. Ultimately, the best choice for you will depend on your hair's needs and your desired styling routine. **
