Yes, hair length does matter.
If your hair is less than 10 inches long, we recommend using one Hairprint kit.
If your hair is more than 10 inches long, we recommend using two Hairprint kits.
If your hair is longer than your midback, you may require three kits or more.
In all of the above hair length situations, if you have chemically treated hair do not apply Hairprint® to your entire head and instead follow our Transition Tips. Please consult the rest of our FAQs for more detailed information.
