Thank you for your question. Ecocolors dark brown would be similar to the color your stylist is using, but before purchasing, why not send us a self addressed/stamped(.80 postage) small manilla envelope to Ecocolors Lab 4760 Hammmermill Rd #106 Tucker Ga 30084 and request a free sample for allergy testing. Be sure to include the color you would like to try for a free allergy test.(dark brown,etc.) You might want to consider using medium brown or light brown if you are not going to get highlights.
