There are 5 ways that I found to straighten hair naturally.
1. Wash and use conditioner on your hair. Use soft shampoo and hair weight conditioner to lock moisture in your hair. Avoid shampoo with surfactant or sulfate, because this can damage your hair.
2. Squeeze excess moisture from the hair using a towel. DO NOT rub your hair because this can cause damage and tangling. Simply press the hair part by using a towel to remove excess water.
3. Use an anti-tangle comb to comb your hair. This type of comb has less teeth so they will remove your hair without getting stuck. Follow with a tight-toothed comb to further smooth the hair.
4. Divide the hair into two pigtails. Pigtails must begin near the nape of your neck; the higher the pigtails will cause more bending in the hair when it dries. Tie it with elastic hair ties.
5. Tie elastic hair ties at intervals along the rune. Every 2-3 inches, tie the elastic hair bands around each twist. Don't tie it too tight or you will create a lump in your hair when it dries. You have to end up with what looks like a "striped" pigtail
