I actually did develop a spray along with the Serum. I gave out some samples but I didn't officially release it.

I might have the lab tweak the formula a bit (although people really liked it as is) and release it at a later time.

The thing with a lighter silicone is that it is going to have a higher concentration of cyclomethicone and a lower concentration of dimethicone/dimethiconol. Basically what this means is that the hair might temporarily feel softer, but the cyclomethicone evaporates quickly and doesn't do as good of a job of coating the hair shaft to lock in existing moisture. A spray would need the right balance of goodies to promote softness but avoid buildup and too much shine.

Like I said, I might try to revisit the spray idea, but I want to make a couple of small tweaks to help it work in conjunction with the rest of the line.

I've also been doing some research and have some ideas for a few other products. More good stuff to come....
