Kronos Phyx Overnight Repair Mask

Is a Solution for:
Thinning Hair & Shedding
November 15, 2008 Reviewed by Marta 7 Comments

Aging hair is perplexing and vexing. It sort of creeps up on you and before you know it every day is a bad hair day. After a while the symptoms start to manifest themselves and one's formerly lustrous locks have become brittle, dull and thinning. And, unlike the skin care market, there are precious few lines that are specifically anti-aging. Kronos is one of the exceptions with a line of anti-aging hair care and the Phyx Overnight Repair Mask caught my eye.

For one thing it costs $105. But more importantly it claims to be clinically proven to work in an independent trial. After four weeks hair strength and elasticity was improved by a whopping 96% and volume by a more modest, but nevertheless welcome, 26%.

Phyx is marred by the usual suspects in the silicone and preservative departments. Then I was surprised to see acetyl hexapeptide-3. This is an anti-aging peptide that works by relaxing muscles in order to inhibit the formation of expression wrinkles. I have no idea what it can possibly do to the hair and scalp.

On the other hand, there are over 25 ingredients that look as if they have the potential to contribute to those trial results. One of those is hexapeptide-11. Studies have shown that this can signal genes responsible for collagen production and it can upregulate the androgen receptor in the way that testosterone can, suggesting that it can help with hair regrowth. Pearl powder is another intriguing ingredient for a hair care product. The thing that makes pearls pearly is called conchilion. As documented in the Journal of Cell Biology in 2006, conchilion acts like the protein keratin (which is found in skin, bones and hair).

Most of the rest are botanicals, including astrocaryum murumuru seed butter. This comes from Brazilian palm and is rich in oleic acid. Also hailing from Brazil is coral powder, which is high in calcium. I just hope it doesn't come from live (and rapidly depleting) coral beds. There are a couple of different types of green tea, plus rice bran to bring antioxidant power. Lycium chinensis is a good source of betaine, an amino acid. Another Chinese plant is cudrania tricuspidata, a kind of mulberry tree that is good for stimulating the circulation. Meanwhile, researchers in Japan have found prunus mume to be an effective scavenger of free radicals.

    I agree that a lot of the new products use the Buzz word of the year like Acai and then say it all roots,berry and fruits .
    Then you read the labels and see it has a whole bunch of chemicals as well.I have heard that if there is less then 2% of some chemicals they do not even have to list it.
    Which doesn't seem right because some people are allergic to certain products natural and chemical.
    We deserve to know exactly what is in everything we are using in or on our bodies then do the research.Warning labels would also be good for certain products.

    I would never use Kronos products. Never. They DO contain harmful ingredients and chemicals. Growing healthy, beautiful hair through simple, natural methods is very achievable without toxic products such as these. I am living proof of it.

    Hmm, some of the above posts are alarming. I admit I have not been as vigilant about the ingredients as others, looking mostly for help against my thinning and brittle, color treated hair.

    I have been using the Kronos mask for 6 weeks now, once a week, and I do have to say that my hair seems a bit stronger and less apt to come out in the shower or break off while brushing. However in fairness, I must also say that I have stopped using chemical hair dyes and have switched to a natural hair coloring product. I am also using Aubrey Organics Rosa Mosqueta deep conditioning regularly and all of these combine to help make my hair much more silky and healthy. So it's hard for me to separate out which product is responsible for what.

    I have also just started using the Nutra Lift Simply Superb Goat Milk shampoo and love it. It smells wonderful and leaves my hair feeling very soft. I ordered it online through TIA and they sent me a free 4 oz bottle of their Herbal Nonsoap, which also smells divine and is a lovely and gentle alternative to soap for the shower.

    Most of the ingredients in your product ARE toxic. Why would I want to put more chemicals and poisons from the on my head? Haven't they done enough damage to the world without my putting the crap on directly. Enough is enough. We have all the ingredients to a healthy head of hair right in our kitchen and health food store, but then Kronos wouldn't be able to make any money off of us. Kronos, your time is running out. And the same goes for Monsanto (Mon Satan) and the Petrochemical industry!!!

    Hi Lily,
    We don't like toxic ingredients (although they are sometimes hard to avoid). But I want to clear things up in relation to butylene and propylene glycol. Glycol’s have extremely wide variations in toxicity that match their many dirfferent uses. Ethylene glycol is very well known as automobile anti-freeze. It is toxic upon ingestion, causing direct toxicity to erythrocytes [red blood cells]. The very similar propylene glycol has none of the same toxicity associated with ethylene glycol. It is both a skin irritant and a sensitizer. You can read our research on PG" rel="nofollow"><a href="" rel="nofollow">here</a></a>.

    Butylene glycol (1,4-butanediol) is not toxic. There has been no documented organ-specific toxicity associated with 1,3-butanediol. Butanediol is also not a carcinogen. It is not a skin sensitizer, and is not considered a skin irritant. In undiluted form butylene glycol may irritate the eye and lining of the respiratory tract.

    I hope that helps.

    This product has toxic ingredients: Propylene Glycol, Butylene Glycol. If it is such a great product then why put in these ingredients?
