1. Glue Hair Straight -
To do this, all you will need is some extra strong glue. Just apply the glue to the hair and pull it through to the ends. Once the glue dries up, apply a good shine serum. Voila! you have long straight hair!
2. Help from your Pet -
How about taking some help from Rocky? Lie flat on the ground with your hair stretched out. Before doing that, put something on your hair that your dog likes to lick, could be anything sweet or salty. Once you lie on the ground, ask him to come and lick your hair. Its gonna be tough to hold his attention but make sure he's at it for quite some time. All the saliva will straighten the hair in no time!
3. Tie Weights -
If you have long hair, tie some weights at the ends and make sure you keep them there for a few days. Its gonna hurt but if you can tolerate the pain, you will have super straight hair!
4. Some help from the kitchen -
For this you will need two plain stainless steel or ceramic plates and a friend to help you. Heat the plates first. and ask your friend to hold one in each hand. Put hair in between the two plates and ask your friend to start ironing the hair with the hot plates from top to bottom. Reheat once the plates get cold and repeat until your hair is fully straightened. Finish off with a shine serum!
