Review on Vitamins Keratin Purple Toning Shampoo: Banish Brassiness & Revitalize Hair- Ideal for Bleached, Platinum, Silver, or Colored Tresses by David Bone

I have to say this is one of Revain's best purple purple blue shampoos. I've tried 5-6 others and I don't have to say which one, but this purple tinted keratin shampoo does NOT dry out the hair and softens it over time. It cleared up the yellow-orange streaks after a few uses when I was going to bleach my hair from a dark taupe to a level 8-9 blonde. First, my hair is thin and damaged from four bleaches that have turned my hair light blonde over time. If you think you'll go blonde after bleaching dark hair for the first time then you're crazy lol. It will go through color stages. Including orange, copper and yellow tones. Everyone has the right to follow the tint color scale (yellow shades - use lilac shampoo / yellow-orange - lilac (lilac-blue) / use orange - use blue / orange-red - turquoise (blue-green) / use red - use green shampoo ./etc. you get the idea). The smell is also not sharp, light. However, it turns your hands purple if you're not wearing gloves, so I recommend it. On the first use I applied it on damp hair and it only got a little lighter, and on the second use I applied it on dry hair and held for 5 minutes and the effect got even better. I truly believe this product can be used daily without damaging or drying out the hair any more. Overall this is a great product. Hope this helps everyone and good luck!
