Hair straightening is not universally suitable for all hair types. The effectiveness and safety of the process depend on factors such as hair texture, thickness, and overall health. People with fine to medium hair often achieve the best results, as their hair responds well to heat and styling. However, those with coarse, damaged, or excessively curly hair should exercise caution, as straightening can cause further damage or breakage. It’s essential to consult with a professional cosmetologist to determine if hair straightening is appropriate for your specific hair type and condition, and to ensure the process is carried out correctly to minimize potential harm.
