Think of your strainers, after a while the products start to
build up on them and you have to clean them. This also happens with your hair making
it start to go dull and limp. Even shampoo and conditioner start to build up
(The nice smell on your hair afterwards is the product left over on your hair).
Now this is a bit of a weird tip but trust me it works! Once in a while use a
sprinkling of bicarbonate of soda with your shampoo and this will help lift up
the products from your hair.
Let me know in the comments bellow if you have and beauty tip you would like to share!
