One of the keys to successful hair serum results is to use a very small amount – it goes a long way! However, I picked up another tip from my stylist that I thought might help you.
Instead of putting a little drop on your fingers to spread on your hair, apply it to the palm of one hand then rub your hands together vigorously. This emulsifies and breaks down the ingredients as well as adding heat to the product. So, not only will you help the active ingredients work better, you'll spread it out for even distribution easy as one, two, three.
