For healthy hair: Add amla to henna
It is said to keep graying in check, you can have the juice of one raw amla daily, after adding it to a glass of water.
You can also add amla to henna powder, for healthy, conditioned and glossy hair. If you would like to try it, you can soak a handful of dry amla in about 2 to 3 cups water overnight.
Next morning, strain the water but do not throw the water away. Grind the soaked amla fruits and add henna powder to it. Then, add 4 teaspoons each of lemon juice and coffee, 2 raw eggs, 2 teaspoons oil and enough amla water and mix it into a thick paste.
Keep the paste for two to three hours and then apply it on the hair. Make sure you apply it evenly so that the entire head is covered. Keep it on for at least two hours and then wash it off with plain water.
