Hello
Unfortuantely cap highlights will not have the same effect as highlights done at the salon. For a professional to do it and to try and do it at home is vastly different because as a client you wont be able to see exactly what is going on on the top of your head and there fore the placement won’t be as acccurate. I also won’t recommend using a home-based bleach and peroxide because it might to things to your hair that can only be fix repaired with a cut if something goes wrong.
