invest in an iron with ceramic plates (like these mini irons). “They disperse heat more evenly than metal ones,” says Sims. As for technique, cap your clamping time to 10 seconds per section. “start out at 95 degrees (150, if hair is thick), and if it doesn’t curl or straighten in that time, turn up the temperature 10 degrees more until it works,” says Atkin. “It’s better to use a higher heat for a shorter time.” IF YOU: Colouring your hair will damage it (most formulas contain dehydrating ammonia), but lightening it—using bleach to strip out the pigment before applying a toner or colour—doubles the damage. THE FIX: Use a weekly oil-based deep conditioner to replenish lost moisture. If you prefer light hair, try balayage instead, or go for hand-painted highlights that will grow out less noticeably (due to the imperfect placement), reducing your salon trips to just two or three a year!
