Best aluminium hair foils 15cm

During the developing process, the foil helps retain heat. This allows the bleach to lift better and more evenly throughout the lifting process. When doing highlights the Hair foil keeps colours separated and acts as a shield so the colours do not seep or transfer on to one another or on the natural uncoloured hair.

Now that you know the difference between hair foil highlights, and hair foils, you may be wondering which one is best for you. The answer depends on what type of look you’re going for and how much maintenance you want to commit to. If you’re looking to switch up your hair color with a full head of highlights, foils are the best highlighting technique for you.
