I’ve been dyeing my hair for about a year now with Overtone. I have really dark, thick, wavy/curly Asian hair. I bleach it underneath the color which does cause damage, but the color deep conditioners help restore my hair so much and NEVER cause any additional damage. I’ve used a ton of different colors and I’ve never had results I didn’t love! These products are definitely more pricey than boxed dyes from the drugstore but they’re so worth it! I’ve used boxed dye in a pinch before and my hair always smells like developer/chemicals for a couple days after and fades after 1-2 washes. Overtone smells great (but the scent doesn’t linger) and doesn’t even START to fade for at least 3-4 washes (and that’s without using the daily conditioners). I can’t recommend Overtone products enough.
