5 /5 Jaylin Contreras: OMG, John is literally a wizard with hair. I came in with jet-black hair, fully expecting it to take, like, a million sessions to go blonde, but John got me there IN ONE SESSION. Like, how is that even possible?! The blonde is sooo perfect, my hair still feels healthy, and Iâve been getting nonstop compliments. If youâre thinking about a hair transformation, RUN, donât walk, to Johnâs salon. Heâs him. Period. Added before and after pics.
