Review: Nice color match - It is permanent, i previously used a temp. color. Do not leave on too long as it darkens quickly and stays that way. I think I will go back to temp. Color.

### ⭐⭐⭐⭐⭐ Gentle, great color, covers stubborn grays!
*by D***4 on April 30, 2025*

The reviews on this product are mixed, and I dont really understand how so I'm writing this to add my two cents.. While on vacation I purchased this from CVS because my grays were really grown out.. The instructions were very easy to follow.. I applied the clear primer, then mixed the developer and color together and began to apply to my roots. After waiting 25-30 min, I could see the color had developed fully and rinsed the dye off in lukewarm water in the shower then applied the included conditioner. My hair came out amazing, felt much softer than my previous brand, the color was a great match and all grays were actually covered! I did notice that when the bathroom was cold, the color wasnt developing as quickly until after I turned a heater on inside the bathroom.. but I've also noticed this with other brands in the past. After my hair dried, it did feel much softer, not as dried out as with the other brand.. and the color lasted without fading until the next time my roots grew out! I actually ended yo switching to this brand and the Toscana color, because its a more natural color and tone for my complexion! After 2 root touch ups, the color looks even nicer since I'm able to see it grown out a couple of inches, and it looks great in the sunlight! As for the "multidimensional" color, I didn't notice any significant miracles with the middle or ends if my hair because I've dyed it so dark the last 15 years, that nothing is going to add any highlights or dimension.. I do plan in using this and we'll see how it looks after the old brand has completely grown out, I can't wait to see my hair completely colored by this brand in the Toscana color. I had a great experience with this product and other brands failed to color all of my grays.. I was definitely impressed by the performance, the smell, it feels more gentle than my previous brand, and my hair doesn't feel as dry or coarse after using this 2 times. I hooe this helps anyone in the fence about purchasing this.. I may update this review again after more touch ups, and I think there are going to be some nice before/after photos too, as the color is more natural on me than any previous dyes I've used.
