Hi , Steemit Friends........
If you treat your hair with Colour, then to protect your hair and to maintain a long lasting Colour on your hair, need to maintain the following steps.
apply Natural oil on your hair, it will helps to retain the moisture in your your colour treated hair.
Shampoo just for 2 to 3 times in a week.
Never Shampoo more than every other day.
Use moisturizing conditioner only on your color treated hair.
