Infuse Hair Strengthener and Thickener- reviewed and recommended
I enjoy using Infuse as well, it is a very lightweight spray that doesn't need to be rubbed into the scalp and it can be squirted on dry or damp hair without leaving a sticky residue.
Intriguingly one of the ingredients, an amino acid called acetyl tyrosine, is supposed to turn gray hair back to its original color - at least, according to a study conducted on kittens. I can't really vouch for this as I don't have too many gray hairs. As I commented in my previous post, Infuse also contains research-backed panax ginseng. There is a Korean study on mice that demonstrated ginseng accelerated the recovery of hair cells and prevented apoptosis in hair follicles.
One of the most convincing ingredients is arginine, an amino acid and its relationship to hair growth is a little complicated. L-arginine serves as a precursor in the body for the production of nitric oxide (NO), which is a gas. NO’s role is to make our blood vessels relax promoting easy blood flow. This, in turn, plays a role in stimulating hair growth. I also found a Japanese study that concluded that arginine can protect the hair from the effects of chemical coloring, even bleaching.
Calcium pantothenate is vitamin B5 and it is frequently found in hair growth products. A study on mice identified skin irritation and loss of hair color as possible results of severe pantothenic acid deficiency.
