No. Here are a few reasons why it seems like it does:

**Hair needs a perfect balance of moisture, protein and other ingredients. If your product regime is too heavy on protein, for example, you may feel the benefits short term, but once the protein is built up, your hair will require moisture to stay soft and supple. This being said, if your hair has been damaged, you may need to build the protein for a while, introducing moisture back after a few weeks.
**The first time you use a product that is significantly better for your hair than previous products, you will experience an epic change in the feel of your hair. This feel will eventually become the normal way your hair feels.
**Hair changes constantly in response to sun, chemicals in the air, water, etc. It is recommended to re-examine your system every time your hair has gone through change.
