OK, full disclosure…I was tempted by several reviews throughout the Net to try an expensive shampoo and conditioner for silver hair. (Davines--total cost was around $52.) I have used it three times, following instructions carefully. It does not make a bit of difference in my hair color, other than to give it a very subtle, odd brownish tint, that goes away after a couple of showers when I soak my hair throughly under the spray. It does not add shine, softness, or smoothness. It has an odd, metallic smell--not objectionable, but kind of weird.
So today I got out my Albert VO5 Tea Therapy Blackberry Sage Tea Revitalizing Shampoo, and the VO5 Tea Therapy Nourishing Conditioner--Calming Chamomile Tea. As Ladystache's know, these products are around a dollar apiece. I washed and conditioned my hair, and 1. The silver color is noticeably enhanced. 2. Hair is noticeably soft, shiny, and smooth without being flat-looking. It has a body and a fluffiness when brushed.3. There is no smell at all.
I feel embarrassed about wasting money, but the Davines did get my hair clean, if nothing else, and the shampoo and conditioner are a pretty purple color. So while I'd rather not have a Facepunch, feel free to give me a good shake for stupidity and being gulled by consumerism.
