I read the b4 color was effective on henna and I wanted to wait until my hair grow and have a root effect or else to cut. I started with little hope and that's the revelation! I'm an idiot, pay almost 200th at Jean Louis David for the same product (I recognize the smell of a thousand) and less effective. I still have a little on the points I would do tomorrow. Benefits: - Walking on henna (except those with metal salts that is specified in the notice) - Removes many layers superimposed - Because I have fine hair, the package makes me 2 applications (avoid any mix if you have fine hair or short, made both as a mixture in a bowl) - The price (insignificant compared to the barber) - Do not damage the nature of your hair, they will be just a little dry to the touch because of the long rinsing
Disadvantages - The horrible smell that remains even after washing (put cellophane to lessen) - Water wastage (product success depends entirely on good rinsing) - A little too liquid product
