Your hair feels dry, brittle and is difficult to manage. It is not retaining the moisture and your natural oils.
You probably wash your hair too often and are heat-styling your hair regularly. Your hair needs nutrients and oils. If you want to spoil your hair use a hair oil based on vegetable oils once a week.
Avoid washing your hair every day and do not use very hot water, rather use cold water to rinse. Do not blow-dry your hair, rather have it dry slowly wrapped up in a towel. If you can, stop dyeing your hair.
