Certainly! Maintaining straightened hair requires proper care to keep it looking smooth and healthy. Firstly, use a heat protectant before styling to minimize damage. Invest in a good quality flat iron and avoid excessive heat exposure. Sleep on a silk or satin pillowcase to prevent friction and frizz. Use a lightweight, non-greasy hair serum to add shine and control flyaways. Minimize washing frequency to preserve your style, and opt for a sulfate-free shampoo and conditioner to retain moisture. Regular trims will help prevent split ends. Remember, a balanced diet and staying hydrated contribute to hair health as well.
