I was also suprised that AC used Saw Palmetto in their revitalise system, as it has a lot of bad press. Having said that, many people (non-users) of this forum do put faith in the herb and maybe they thought by adding it to their spray, the Saw Palmetto users would make the switch from oral tabs, to topical. And its unlikely that topical Saw Palmetto would do any harm, and it may have benefits in male pattern baldness (there is logical arguments for its use) the reason it has so much bad press is because some snake oil salesmen make wild claims about its effectiveness (Ive even heard 99% success rate) and charge stupid prices for it.
Think about it: AC pay intercytex god knows how much to use their patented copper peptide formula, but the use of copper peptides in male pattern baldness is pretty much unheard of away from these forums (even though it is semi-clincally proven) so they would want to use some ingredients such as Saw Palmetto that people could relate to helping hairloss.
After all is said and done, AC revitalise is an excellent set of products. Cant recommend it enough.
