Which is better for me - the Spray or Foam?
Whether you choose the foam or the serum really comes down to personal preference. Some people prefer the spray because they don't have to get their hands covered in product, and others find it easier to apply the foam. Many customers have found that the spray is great as long as your hair is fairly thin - the spray can then get to the scalp without a problem. Once your hair is thicker, it can be easier to work the foam into the scalp.
