Way better than the Keratin treatments I used to get at the salon. It doesn't have that harsh chemical smell and I can do it at home. My hair looks healthy and actually has some movement instead of being pin-straight and flat.

My driveway was looking pretty rough after the winter freeze-thaw cycle. I was worried about water getting under the slab and making it worse. I used this ConSandtrate stuff and it filled the gaps perfectly. Pro tip: make sure you clean out the dirt first or it wont stick as well. It’s holding up great against the car tires so far. Very happy with the purchase.

It's okay. The scent is really strong on the peppermint side, which I didn't expect. It's definitely moisturizing, but I feel like I'm paying a lot for the brand name. Probably wouldn't buy again unless it was on sale.

way too expensive for what you get. It looks nice for a few weeks but then starts fading just like the cheap stuff. I followed all the instructions and honestly dont see the "superior protection" they keep talking about. save your money.
