  • Sorry but I don't have any info on this product. We typically don't cover weight loss products as they are not cosmetics.  
  • Nail polish formulas are quite complicated so adding nail polish remover may help but it also may destabilize the formula. Depends on a lot of variables like how much you're adding, what's in the remover, etc.  Elmer's is not designed for prolonged …
  • Salt is more likely to be a problem when left on the hair. This shampoo bar is a rinse off product. (Most shampoos have some level of salt anyway because it's a by product in the surfactant manufacturing process and it's often used as a thickener. 
  • In one of those books we proposed that idea as a hypothesis for how one might become addicted to lip balm. But lip skin is different from the rest of the body and I don't think that vicious circle really exists. 
  • It's certainly true that shampoos without any conditioning agents can leave hair more tangled. The good news is there are a million different shampoos you can try until you find one that gives you the right amount of detangling without giving you bu…
  • It's true that paraffinum liquidum is mineral oil. It's NOT true that it locks toxins in your skin. You can read more about mineral oil myths here:  The top 5 myths about mineral oil part 1 Myths about mineral oil part 2
  • I had forgotten that DECIEM makes Inhibitf. 
  • Titanium dioxide is not just a sunscreen. It's also used to whiten a formula or to make it more opaque. I think that's the case in the Olay product you mentioned. Based on where it appears on the ingredient list there's not enough there to be a func…
  • If you can hydrate and soften the skin before pushing back the cuticle it should make it a little bit easier. But just about any lotion can do this. I too have seen more harsh products that may work better but may also irritate the skin. It's a matt…
  • This looks like the Manicare Cuticle Remover product. To be honest, I don't see how it could provide much benefit beyond perhaps moisturizing/softening the cuticle via the glycerin.  Also, FYI, I edited the title of your post to include a little mor…
  • Hair "masks" are more of a marketing difference than a technical difference. There are no special ingredients that are used in masks and not in regular conditioners.  You could certainly benefit from using coconut oil. Some people swear by it others…
  • Thanks perfectly fine, Hanita. Thanks for thinking of us!

  • It's tough to say because the lactobionic acid appears after Polysilicone-11 (which is probably used at 1% or more) and before all the extracts (which are probably used at MUCH less than 1%. ) I don't know how often you should use it because it dep…
  • This is a very gray area but basically it comes down to this:  The FDA gets involved only in drugs not cosmetics. The definition of a drug means that the product interacts with the physiology of the body; cosmetics can only cleans and affect the app…
  • Hi Alexandra. Based on everything I've seen I believe Peter is correct. Thanks Peter for all your comments!
  • Yep, all good suggestions. 
  • Interesting. I'm not a biochemist but I don't really know what to do with this information. We know from years of studies that ceramides are an important part of the skin's moisture barrier and that topical application of ceramides can benefit skin.…
  • Polyquaternium-7 is a conditioning agent that will stay on your hair after rinsing. 
  • Hydrogenated Castor Oil/Sebacic Acid Copolymer supposedly sticks to lifted cuticles and cements them down. Theoretically this can help with split ends.  Dimethiconol is a more water soluble version of dimethicone which means it gives less buildup bu…
  • Thanks for recognizing that isn't as easy as some people think! And here's some good news - we just recorded another episode. Look for it next week. 
  • We've talked about this before: http://thebeautybrains.com/bbforum/index.php?p=/discussion/comment/1577/#Comment_1577 Here's a recap of my answer: Olaplex is a 3 step process that is said to rebond/repair hair. As far as I can tell (mostly from the…
  • Well, the best science to data says parabens are fine so I don't see the problem there.  Hydroquinone is ok when used properly. It's still the gold standard for skin lightening. 
  • We've received questions about this product in the past but we haven't gotten around to writing our response. When I get a chance I'll dig into to this more but in the meantime I reached out to the company for more information and here's their respo…
  • It depends on the product, the packaging and how you store it. In some cases, 5 years is not unreasonable. If you're talking about a product that could easily become microbially contaminated and infect you (like a lip balm or a mascara) 5 years is W…
  • Lash growth products have been controversial since a certain class of glaucoma drugs (prostaglandins) were found to really work when applied topically. The problem was this drug could permanently change the color of your eyes! A couple of companies …
  • You're welcome! It's nice to hear that our style suits you. You'd be surprised how many complaints we get from people who say we ARE condescending and that we're "intellectual bullies." I just don't get it, we're just trying to help people be smarte…
  • Retinoids are very effective skin care ingredients but retinyl palmitate is the least effective version. Check out this podcast for more information: http://thebeautybrains.com/2013/11/the-beauty-brains-show-episode-06-which-retinol-is-right-for-me/…

  • I didn't say the cleansers you found are not good I just said they don't contain any active ingredients that are typically used to reduce the appearance of large pores. You are right, though, that products with such ingredients are often too drying.…
  • My guess is that the thicker products tend to be the ones that use petrolatum which is the most effective occlusive agent. (Meaning it locks in moisture better.) Petrolatum tends to make products have a heavier texture. The thinner products may be u…
  • As we discussed in the podcast, my understanding is that cleansers with sal acid or some other active that can help clear our pores is best. I don't see those ingredients in any of these products.  I don't see how oil cleansing would help that much …
