I've just received a couple of samples from PureRadiance, a new brand launched by a Al Sears MD. For a start, I like the approach: PureRadiance focuses on nutrients and actively avoids "parabens, carcinogens, pollutants and gasoline distillates that are commonly found in most of today’s cosmetics and skin care solutions". Over the coming weeks I'll be trying out the serum with new it ingredient, teprenone
, that promises to stabilize our telomeres
and the Infuse Hair Strengthener and Thickener ($49.95).
There are plenty of botanicals that are said to help against hairloss, but one of the few that can summon research to prove it is panax ginseng. There is a Korean study on mice that demonstrated ginseng accelerated the recovery of hair cells and prevented apoptosis in hair follicles. Articum is burdock and it is supposed to control dandruff as well as being a DHT blocker. I was intrigued to see fenugreek as I don't believe I've come across it in a hair product before. Although it is said to prevent hair loss, Sloan Kettering
says there is no evidence to support this.
There are a number of amino acids here. They are the building blocks of hair and I believe there are 18 of them in our hair. I'll pick out a couple of those used by Pure Radiance. Arginine is 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.
Infuse also contains acetyl tyrosine, another amino acid. I was about to dismiss claims that it can stop hair changing color (presumably from going gray) as hogwash until I found a study
on kittens conducted by the University of California that proved that it can.
The "paraben-free preservative called Germall Plus is actually a combination of diazolidinyl urea
and iodopropynyl butylcarbamate
(which may cause dermatitis) solubilized in propylene glycol.
