Did you know onions contain sulfur? Did you also know it was this sulfur that had the power to trigger hair growth when onion juice is rubbed on the scalp?
To extract onion juice chop up a large onion and pulverize it using a food processor.
Then squeeze out the juice and using a cotton ball apply the juice on the scalp. Leave on the scalp for half an hour and rinse with warm water and a mild baby shampoo. Do this treatment twice a week.
Onion juice is also good for getting rid of scalp pimples.
