GRO+ Advanced Hair Foam

I prefer the foam over liquid because I can better control the size and application, but sometimes the bottle itself interferes with this foam's advantage. For example, every other bottle explodes a huge amount the first pump, and every single bottle loses its steam too quickly and the last few pumps (if I'm lucky to get even that) is watery. If I collected all the last drops I couldn't get because of the bottle's deficiency, I would have a new bottle. Despite this shortcoming, it does what it claims to do: my hair doesn't fall out so easily when I'm shampooing, I see new baby hair growing, and my hair divide isn't as large (oh, I use this product WITH the GRO+ shampoo and conditioner, in case that's important). So, all things considered, I give this product a 4.

This was the worst product. It was not only so tiny that it should really be classified as travel size, but it failed to really sink into the scalp to do anything. You would need about several cases of this product to get about a week's worth of use unless you have a baby-size head. I was shocked at how little product there was in the bottle and at the end, the product didn't produce the foam/mousse that it produced at the beginning (came out super-watery). I felt so deceived by this product that it really has dissuaded me from using the serum again.
