Which thermal styling temperature range is most appropriate for fine, fragile, or chemically treated hair?
a.400 to 450°F (205-232°C)
b.375 to 400°F (190-205°C)
c.350 to 375°F (175-190°C)
d.Under 300°F (under 150°C)
Explanation
Fine, fragile, or chemically processed hair should be styled under 300°F (about 150°C) to limit cuticle damage. Medium hair generally tolerates 300-380°F, and very coarse or resistant hair may need up to 400-450°F, but the lowest effective temperature is always preferred to preserve hair integrity.
