Cinnamon is a natural and inexpensive way to treat hair loss, dandruff and also lighten hair naturally. *seriously, it does lighten your hair so I suggest only using this if you have lighter hair or are looking for a lightened shade. It's not drastic but just a warning :) Cinnamon hair mask treatment: The best way to stimulate hair growth and add an overall shine is by using a cinnamon mask. You will need: Cinnamon Olive Oil To use: - Take 4 tbsp of warm olive oil and combine with a tsp cinnamon powder. - Part your hair and apply liberally on the scalp and gently massage it in for better effects. - Leave it on for 10-15 minutes. If you feel a tingling sensation then don’t worry, it is just the mask working on your scalp. - Rinse the mixture off with a shampoo.
