I'm sort of mixed on this product on whether I'd recommend it or not.
It's a lightweight spray (non-aerosol) that you spray into your roots and then blow dry to achieve volume. Unlike the Got2b Fat-tastic Collagen Root-Boosting Spray (which I have reviewed) I find that I can't achieve volume from just blow drying the product without using a round brush.
The Sally Hershberger Supreme Lift does make a difference to my hair (I have before and after pictures on my blog if you'd like to see) although not a huge difference.
What I like about it is that it doesn't accumulate in my hair too much - it just leaves a bit of tackiness.
In comparison to the previous voluminizing spray I used, Got2b Fat-tastic Collagen Root-Boosting Spray, the Sally Hershberger Supreme Lift doesn't leave as much residue. That's great because I'm not obligated to wash my hair that same day in order to rinse out the residue from the styling product. However, considering that the Sally Hershberger Supreme Lift is twice the price of the Got2b Fat-tastic Collagen Root-Boosting Spray and it didn't give me more volume, I'm not sure if I'll be repurchasing the Sally Hershberger Supreme Lift right away.
