Yes it matters. Use clear or white distilled vinegar. The cheapest stuff you can find works.
The better one is whichever one is the easiest to get and the cheapest. I believe somebody sells a concentrate that you mix with water. I think that is the cheapest. Laser Sheen maybe?
I am telling you,the label on the bottle is what we are all paying for. There just isn't much difference between daily hair care products or Sheen. Check out the post in the Hall Of Fame section. You can make yourself up a pretty darn good product for 1/4 the price.
