Vinegar, lemon juice or beer?

Hi Elisabella!Of the three the vinegar rinse is the safest bet as ituses a low pH to lock down the rough outer hair layer (cuticle)imparting shine, eliminating tangles and temporarily sealing split ends. Beer has enzymes that can be restorative for hair, however, they must be broken down into the right molecular size and weight in order to be readily absorbed into the hairshaft where they can do some good - Back to Basics has a line of beer enzyme-based shampoos that are hair specific, as opposed to beer thatis, well, uh...stomach and brain specific. :)If you want to get the benefit of a vinegar rinse without smelling like a salad, try Infusium 23 in the professionalformula. While it does not contain vinegar it mimics the same low pH with natural citric acids that will not harm your hair like lemon juice.In your service,Mickhael> I have long, blonde color-treated hair.
