* Heat + Grease = Cooked Grease: When you apply heat from a flat iron to greasy hair, you're essentially cooking the grease onto your hair shaft. This can make the grease even harder to remove later and can weigh down your hair.
* Uneven Heating: Grease can create a barrier that prevents the heat from distributing evenly across your hair strands. This can lead to inconsistent straightening and potentially damage your hair in some spots more than others.
* Increased Damage: Grease and oils can attract and trap more heat against the hair shaft, leading to excessive heat damage such as dryness, breakage, and split ends.
* Dirty Flat Iron: The grease and product build-up will transfer onto your flat iron plates, making them dirty and less effective over time.
* Bad Results: The end result will be far from ideal. Your hair will likely look limp, greasy, and potentially even dirtier than before. The style won't last as long either.
What to do instead:
1. Wash your hair: Use a shampoo that effectively removes grease and buildup. A clarifying shampoo can be helpful if you have a lot of product buildup.
2. Condition: Follow up with a conditioner to hydrate your hair.
3. Dry completely: Make sure your hair is completely dry before using a flat iron. Use a heat protectant to shield your hair from damage.
4. Flat iron clean hair: Now you can flat iron your clean, dry hair for the best results and minimize damage.
