Why the effect on styling on the hair structure?

Styling products and techniques can significantly affect hair structure by altering its moisture balance, cuticle integrity, and overall health. Heat from tools like straighteners and curling irons can cause protein denaturation, leading to dryness and brittleness. Additionally, chemical treatments such as coloring or perming can weaken hair bonds, resulting in increased fragility and breakage. Consistent use of harsh products can also strip natural oils, further compromising hair's strength and resilience.
