Good news...I think that is highly unlikely. They just changed their packaging not too long ago and the RHG got a facelift too.

Since technically Walgreens Biosilk products would be diverted, I think it's much more likely their supplier is having trouble providing or sales at Walgreens or even that specific Walgreens weren't good enough for them to continue carrying it.

I'd get concerned if I saw Trade Secret for it on clearance but not Walgreens.
