Proper shampoo for your hair type

See whether you are using the proper shampoo for your hair type. Is your hair fine, dry, oily or did you see some dandruff flakes lately? Since shampoos are made from water and organic compounds, contamination from bacteria and other microbes is possible. Preservatives are added to prevent such growth. Two of the most common preservatives used in shampoos are DMDM hydantoin and methylparaben.
