Did you know that you can thicken and regrow your hair by simply using castor oil? Becauce of all of the minerals, proteins, and vitamin E the stuff packs, it’s an excellent choice for the job at hand. Here’s what Complete Health and Happiness says on the subject:

Castor oil is loaded with omega 9 fatty acids, which nourish the hair and follicles. Castor oil is able to penetrate into the pores and follicles that produce hair. Just massage a couple of drops of castor oil into your  hair.

WikiHow gave us some more detailed instructions for how (and for how long) to apply castor oil to hair:

1. Put on some protective clothing (to avoid staining good clothes) and pour oil into a container.
2. Section your hair into two equal parts. Wet your fingers, then start applying the oil to your scalp with small round circles.
3. Once you’ve finished with your scalp, apply remaining oil to all of your hair.
4. Wrap your hair in a warm towel or hair cap and leave for at least 2 hours. If you can leave it on overnight, that’s even better.
5. Shampoo and condition your hair as usual.
6. Repeat steps every 7-10 days for best results.
