To minimize hair loss, avoid using strong chemicals on your hair. Permanent hair colors and perms can damage your hair leading to further loss. If you do color your hair be sure to choose formula's that are gentle and contain conditioning agents.
If you are losing your hair choose natural conditioners and hair and scalp treatments that are rich in amino acids and proteins to naturally thicken the individual hair shafts. This will give the impression of thicker and fuller hair. After treatment allow your hair to dry naturally rather than using a damaging blow dryer.
