Frequent re-coloring will make hair look more duller.
So, here is a natural method to make long lasting hair dye using peel of layer over garlic.
PROCEDURE to make natural hair dye :
1. Take garlic peel(outer skin like layer) in large quantity because on making ash it will come to small quantity.
2. Roast the garlic peel on a pan till it becomes black ash.
3. Filter the ash to get fine powder with a cotton cloth.
4. Add olive oil to this ash to make it just like hair die.
5. Preserve it for 7 days(do not store in refrigerator) in glass bottle in darkness.
6. After 7 days apply it to hair in the same way as hair die. Preferably apply it at evening times and have head bath next morning.
