5. Dull appearance and lack of shine:
   A dull appearance is another symptom of heat damage. Damaged hair often lacks the luster seen in healthy, well-moisturized strands. According to a 2019 article in the Journal of Cosmetic Dermatology, heat-treated hair has disrupted cuticles, leading to less light reflection. This can make hair look lifeless.

6. Frizz that appears more pronounced:
   Pronounced frizz is a result of heat damage. When hair cuticles are damaged, moisture can seep in, causing strands to swell and frizz. A collaborative study by the University of London and the University of Toronto (2021) highlighted that heat exposure increases the likelihood of frizziness. This can complicate styling efforts and lead to an unkempt appearance.

7. Uneven curl patterns or straightness:
   Uneven curl patterns or straightness can signify heat damage, especially for individuals with naturally curly or wavy hair. Damage may cause some sections to lose curl definition altogether. Research from the Journal of Hair Science (2018) points out that excessive direct heat can alter natural curl patterns, leading to inconsistencies in styling.
