Is the Inversion Method Effective? Women have gone to great lengths and done bizarre things, such as rubbing cow manure on their scalps, for the mere possibility of increasing hair growth. Usually, the methods used are passed on by word of mouth and have little scientific evidence to prove their efficacy. I will be designing an experiment of one specific method for hair growth, the inversion method. The individual begins by sitting in a chair and slowly leaning all the way forward. They then massage their scalp with an oil of their choice for 3 minutes and slowly rise back up. This is to be performed once a day in 1 week increments. The idea is that you are increasing circulation throughout the body, which will help hair to grow faster. This method is said to have been used for thousands of years. There are testimonials all over the internet from women who have attempted this and succeeded with results in as much as …show more content…
There will be two groups of 300 ethnically diverse women varying in age from 18-35. Group A will be the control group and these women will not be using the inversion method, they will go about their daily lives. Group B will use the inversion method for 2 of the 5 weeks (not every day because of health risks and chance of immunity.) Both groups will have their hair measured at the start of the experiment, then once a week for 5 weeks for accurate amount of hair growth. The dependent variable will be the amount of hair growth of each woman. At the end of the 5-week period, the total hair growth for each group will be averaged and compared. Women in both groups will have their hair measured once a week for 5 weeks. If the inversion method was effective, group B (experimental group) should have a higher average of hair growth within the 5 weeks than group A (control
