  • Well, I guess it depends on if the herb contains any oil soluble components that provide skin benefits. For example, rosemary, sage, and oregano do have some antibacterial properties. So IF an oil infusion contained sufficient amounts of these activ…

  • There is some testing in this regard but who know if if it'll ever be successful. 
  • You must have read Perry's profile. He's the one who claims to be an inventor and futurist. You raise some interesting questions but they're probably not the typical problem/solution issues we deal with on the podcast.  
  • "The machines are learning and we all need to run to the woods now while we can."  Lol. Yes, we should just give them nuclear weapons and a copy The Matrix and get it over with.  Thanks for the link! I updated the post.
  • It's hard to say without knowing exactly what the stylist does to you your. You say the doesn't dry it but does she cut it? (That would get rid of fly aways.) Flat iron it? (That would certainly smooth it.)  She must be doing something else besides …
  • Occlusivity typically means an ingredient will form a water proof layer on the skin that will keep moisture from evaporating. That doesn't necessarily mean an occlusive ingredient will prevent other ingredients from getting into the skin. (Assuming …
  • There doesn't appear to be any that special about Juvalift.  It contains (among other things) Ceramides (which are used in a lot of products) Retinol Palmitate (which is about the least effective form of retinol), and Palmitoyl oligopeptide (a pepti…
  • Hi Kirsty. There are three potential problems with old makeup: 1. Does it still work? Some active ingredients can lose efficacy over time. (Probably not an issue with lipstick.) 2. Is it still aesthetically pleasing? In other words, does it look and…
  • Hi Vic. Yes, vitamin C is a great anti-aging ingredient. This post (and podcast) should answer a lot of your questions about Vitamin C: Which kind of vitamin C is best for skin? Episode 31 Hyaluronic acid (when rubbed on your skin) does NOTHING to b…
  • Sure, Anna, you can just post it to the Forum. 
  • Bleach breaks melanin apart but there's still enough there to give you color. (It mostly breaks down the non-yellow type of melanin which is called eumelanin. The melanin which provides most of the yellow color is called phaeomelanin.) Gray hair doe…
  • I suppose it's possible but collagen is not as good of a humectant as glycerin, hyaluronic acid, or other commonly used materials. I certainly agree that the claim is based on APPEARANCE.  
  • Thanks, I just added this one. 
  • You're right.  To be completely accurate, the claim should be written with commas:  "Hydro-gel under eye patches, formulated with collagen, to revitalize and improve appearance around eyes."  This way it's clear that the product (NOT the collagen) i…
  • Ling: I just added a couple of beauty science blogs to the post we wrote last year: http://thebeautybrains.com/2014/06/18/the-best-beauty-science-blogs/ Thanks for reminding me to update it! 
  • Interesting article. Unfortunately, when it comes to cosmetics, if the industry didn't subsidize research then it probably wouldn't get done!
  • Yes, technically you can use these bars head to toe. Of course that doesn't guarantee you'll like the way it makes your hair feel. You'll have to try it and see. I believe DOVE makes one that you could check out.   
  • I guess "gold standard" is in the eye of the beholder but we're big fans of bars based on sodium cocoyl isethionate.  It's mildness very mild and it doesn't have the negative effects on hair that true soap does. 
  • "Unscientific" pretty much says it all. This idea is so ridiculous that I was surprised to find so many articles in a quick web search. But even most of these articles said something like "such and such dermatologist says there's no research that pr…
  • Turchese: I've been reading up on rose hip oil and it looks there is not a quick answer. I'm going to do some more research and, depending on what I find, I may use this as a question for a future podcast.  Would you be interested in submitting an a…
  • Thanks Torches. I'll looked at their website and I don't see any reference to lightening hyper pigmentation. And, none of their clinical studies reference lightening skin. I suspect that what you've seen on other websites is just other people's inte…
  • That's a great question! Let me see what I can find out. 
  • There are conditioning agents that can be incorporated into clear shampoos (e.g., Polyquaternium 7 and 10) . However, they are not the most effective type of conditioners. The most effective conditioning shampoos use conditioning agents (e.g., dimet…
  • Proteins are beneficial to hair because they're film formers than can help smooth and protect. When they're hydrolyzed the proteins are chopped up into little pieces that don't really do much of anything.  
  • You're right, Rogaine is the only treatment that's proven to work. Most people can use it without any problems but since it is a drug there is a chance for side effects. To quote WebMD:  "Rarely, this medication can be absorbed through the skin and …
  • Leave on products do coat the hair, although it's not necessarily the proteins. It also increase friction between hair shafts which boosts volume. 
  • We were speculating when we wrote that post back in 2008. We have not seen any data since then that proves that sulfates solubilize 18-MEA better than other surfactants. The primary issue with sulfates that is supported by data is that some sodium l…
  • We've never tested this Joico product but it does have a good slug of silicones so I would expect it would smooth and protect hair from heat pretty well. (It certainly won't mend split ends, however.)  If you like the way it makes your hair feel - u…
  • The problem with using conditioning styling products is that they don't protect your hair at a very critical stage - when you're drying and detangling wet hair. You might try using a leave in conditioner as a rinse out. Leave in products aren't desi…
  • The particles of alcohol from a hairspray are very small and evaporate very quickly. That's why hairspray's dry so fast. They won't do any damage to your hair or scalp.  Hairsprays are "inhalation tested" to make sure they don't enter too far into t…
