Will my hair grow if it's heat damaged

Yes it will grow back.Using heat can be damaging and break hair clean off.Never use straighteners on a high setting or 200 degrees.175 degrees is better.Don't use products that contain bleaching agents.Use a good quality shampoo and then a conditioner.This will keep your hairs separated and help prevent breakages.Look at your brush or comb after using them there should be few hairs there and none is best.Don't force a brush through knotted hair.Detangle.
