Those who have oily hair never know whether they are washing it too often or not often enough. They end up with fragile hair and are afraid of it becoming even weaker. But hygiene is very important. Smog and dirt suffocate the hair bulbs and alter the production of oil produced by the sebaceous glands. The moral of the story is: wash your hair two or three times a week with non harsh shampoos with phytotherapic extracts, such as the BioKap Beauty Line. Then always rub in the recommended Lotion.
