Egg is one of the best conditioners for our hair. And, massaging hair with egg is one of the best things one can do to grow hair. Egg has lot of protein content which is very useful for the health of our hair.
Start massaging egg into your hair for 45 minutes. And, you would see results in as less as a month. But, 45 minutes might be too much so make it 15!
And, yes, the smell. Try adding essential oil, may be! Rosemary, peppermint, thyme are all great hair growth promoters.
