Infuse Hair Strengthener and Thickener- reviewed and recommended

Is a Solution for:
Thinning Hair & Shedding
December 5, 2009 Reviewed by Marta 7 Comments
For the past month, I have been testing Infuse Hair Strengthener and Thickener ($49.95) by PureRadiance, a new brand launched by a Al Sears MD. Using it in conjunction with Nutra-Lift's shampoo and conditioner (sometimes alternating with Aubrey Organics), my hair definitely looks a little thicker and healthier. I think this would be a helpful product for someone with moderately thinning hair.

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.

    Seriously? you're quoting tests done on kittens?

    I wish you would spend some time at the web site. Animal testing doesn't prove a thing. And it's simply wrong.

    Please , please , please . I really want to try this. I want my hair to grow longer and healthier. I had to get about 4 inches cut off due to damage and I am chugging every vitamin I can get my hands on that helps hair growth. I will write a very truthful insightful review.

    I'd love to try this product and review it. I've been having great luck with some new products - Ctonics shampoo and conditioner, Surya henna cream - and would love to add this to the mix!

    Joan, good catch. That should be B5 and it has been amended.

    Correct me if I'm wrong, but I believe calcium pantothenate is B5 and not B6. The study you linked to showed that B6 was helpful (when injected), but that oral B5 was not.

    The study does not mention either's effect when used topically.

    Where would one find this product? Could this product possibly help with hydrogen peroxide production that has been determined to cause gray hair.
