Hydra Source Daily Leave-in Tonic for Dry Hair

Hydra Source Daily Leave-in Tonic for Dry Hair by Biolage is a haircare product. Most of the work happens at the mid-lengths and ends — the scalp takes care of the roots on its own. Use less than you think and add more if you need it; excess product is the quickest route to a flat, greasy finish. Whether it is discounted this week says more about the shop's stock than about the product. Heat is what breaks hair over time, so pair styling with a protectant and the lowest temperature that gets the job done. The best deal and the cheapest sticker price are not always the same listing once delivery is counted.
