Paul Mitchell products [ well the ` waxworks` styling product] has been given the thumbs-up on here before,so I guess the one on your link would probably be good.... I think though, that living where you do, even the very best product/s will not entirely prevent colour-fade... having said that, it /they will certainly help...is it possible to just pop on a light baseball-cap, loosely, when out and about? I know that`s not always possible/practical though....even where I live, when we get the sun, if I`m working outside I`ll always pop on a such a cap......even growing hair is faded by the sun, but it grows out in time, in it`s normal colour...systems are sitting ducks when it comes to the sun. You can of course re-colour your hair, but it`s better to minimise prolonged sun-exposure as much as possible... I use a daily leave-in conditioner which has sunscreen in it..you can Google it -- `` PPI Enhance``--- I find it to be an excellent product...a few wearers have told me by e mail lately that they too find it to be very good..... obviously it too would have it`s limitations in terms of the sun being so ` strong` where you are, but it`s a great conditioner, and very reasonably-priced. By all means, use whatever sun-screen or product containing sunscreen which appeals to you.... colour-fade is one of the usual issues we face, especially in summer time. Regards.
P.S. this is the link to the makers of ` Enhance` [ Premier products Inc.,] ...there are other product-sellers who carry/sell it, if you`re interested in ordering it....the Google search will show you those, but this is the product-maker`s site: http://www.ppi.cc/conditioners_hair_replace.htm
