I just read this blurb in this month's In Style magazine. I have not used this product and so I can't vouch for it from personal experience, but it sounds interesting:

Kairos Acne Care Solutions Clarifying Complexion-Clearing Shampoo ($24, kairosclear.com)

"A shampoo specially formulated for acne-prone skin. It contains 0.5 percent salicylic acid to prevent breakouts along the hairline and shoulders."

If anyone gives it a try, please report back ?

Its just like any other salicylic acid body wash.

Yeah, exactly. Just with a bigger price tag.

Right ... but I don't know that I'd use a body wash on my HAIR. I battle the frizz enough as it is.

A lot of people use nizoral, because it helps with dandruff and zinc helps with acne. They use it as a body wash also. The same with head and shoulders shampoos.

I've tried L'Oreal Elvive Anti-Dandruff Intense (the strong stuff in the dark blue bottle!) and I've found it really effective as a shower gel on my moderate back and chest acne. Plus it really gets rid of dandruff too, straight away. The best bit is it's only £3.99! Worth a go I'd say.
