Rapida entrega, excelente producto lo mejor para mi tinte.

Buena calidad. No pica el cuero cabelludo.

have been using for years!

I am a regular user of this product.

My hairdresser uses this product and was kind enough to share. I have to color my hair every three weeks and I have stubborn grays. I haven completely satisfied with results. I do recommend using their developer. I have used others, however I used their developer for the first time yesterday and am thrilled with results. Really stuck to my finest baby hairs.

Worked great

ok

Love the quality of this brand! My hair doesnt get damaged when I dye my hair with their products!

You can use this in several applications its alot of the product which made it a great value deal for me.

Great product! You get so much product for the price, I dye my hair quite frequently, and I have yet to buy more developer.
