Getting Back to Natural Hair Color?

I have had blonde hair for the last 50 years. I have medium to dark blonde hair and I am just tired of touch ups every 4 or 5 weeks. If I use a semi permanent red before I use a permanent light brown or dark blonde will the color fade or should I use permanent light red first to avoid fading? My hair is stripped, all but the roots which are growing out about 1/2 inch. Years ago I had my hair reversed frost where a professional pulled my bleached blonde hair thru a cap, put red on the pulled hair and then a light brown, it turned out beautiful with streaks of blonde and light brown.

That was over 35 years ago and now I can't find someone to understand and do this again as it was not too noticeable growing out. I guess it's too much trouble to go thru the cap and doing 2 colors. It worked great back then. Thank you for your comments. I am just not sure about a semi permanent color and the fading.
