Aug 07, 2013 - This sealer provides good heat-protection and lots of shine. I used a lot of this product and didn't find it to be greasy at all. Heat-protectants tend to weigh my hair down and this product did not. And while it did a good job of making my hair look hydrated and almost frizz-free, the results were short-lived. I have to keep reapplying throughout the day. The past few times I've used this line of products, the weather hasn't been optimal (temp 74 F & dew point 64 F) . Under these conditions, the products do just an okay job.
