Definitely agree about consulting with a professional stylist! I was also stuck trying to decide between different coloring techniques. Before my appointment, I took this quiz at https://glaminati.com/hair-coloring-techniques-trends-quiz/ which helped me understand the difference between balayage, ombré, highlights, and other techniques. It suggested some options based on my hair type and maintenance preferences. I realized I didn't want something that required touch-ups every few weeks. The site had great before and after photos that gave me a better idea of what would work with my face shape and skin tone. Ended up with a rooted blonde look that's much easier to maintain than my previous all-over color
