Bblunt is a truly brilliant hair care brand and so I was very pleased to see that they had launched a dry shampoo. Here’s the low down on the new Bblunt Back to Life Dry Shampoo. If you’re looking for something a little different from all the dry shampoo out there, then you need to check this out. It is really easy to use. You simply hold it in an upright position, open the cap and then gently squeeze the bottle to puff out the product.
