  • If the objective is to protect your hair from the damage caused by washing and drying, this won't be as effective as using a regular coconut oil treatment because it won't penetrate into the hair the same way.
  • Even though I don't agree with the EWG, they do have a good database of products and ingredients. I searched for shampoos with Sodium Methyl Cocoyl Taurate and found 78 different ones for you to peruse: https://www.ewg.org/skindeep/browse.php?ca…
  • If you have dandruff of other skin conditions of the scalp, shampoos with sal acid can be helpful. (Provided they contain enough of the ingredient at the right pH.) Otherwise I'm not aware of any proven benefits.
  • You can buy pH test strips on Amazon. Just dip the strip in the product and then compare the color on the strip to the control colors on the package of the strips. The number of the package color that matches your test strip is the pH of your produc…
  • Is your hair bleached or other wise chemically processed? If so it's possible that the charged conditioning ingredients (e.g., the guar) are over-depositing on those spots and causes the problem you're experiencing. Just a guess.
  • I could have sworn I just answered this question but I don't see it in any thread now. Have you previously posted this? Anyway, the quick answer is that it's very hard to make a clear shampoo that conditions as well as "creamy" one. The opacity …
  • In general, bleaching can damage hair which leads to breakage. Bleaching of certain colors can shift the shade.
  • I haven't seen their data but I assume if the product is less irritating then people will be more likely to use it and therefore will see better results. That's how these comparisons are typically done.
  • We discussed this product line a little bit in this post: http://thebeautybrains.com/2016/01/can-you-exfoliate-your-feet-with-listerene-and-vinegar-episode-116/
  • Cyclopentasiloxane is more volatile, I believe. Also it's a good solvent for dimethicone which is frequently used in these products. Finally, it doesn't interact with skin much where limonene can be an allergen/irritant. (and it doesn't add a scent …
  • I've tested similar products in the past and found that they didn't really provide that much of a benefit. But of course, your experience may be different.
  • Yes, oils can help smooth the cuticle. Will brands reformulate? Yes once it's clear that there are regulatory concerns.
  • Hard to answer this one in general because it depends on what's in the specific product. The moisturizing effect is a function of the occlusivity of the ingredients (how well they seal moisture in the skin) and how evenly the product is applied/to a…
  • This is a pretty standard concoction: mostly cyclopentasiloxane followed by some oils. It's nice that it contains a little amodimethicone which might help a little with static flyway. These product coat the hair and smooth the cuticle to add shi…
  • Water evaporates at pretty much all temperatures but the effect is so slight that you don't see it happening. But at the temperature of 100 degrees C, the water molecules have some much energy that the the vapor pressure of the evaporated molecules …

  • You might find this helpful: http://thebeautybrains.com/2014/01/pore-minimizing-myths-the-beauty-brains-show-episode-012/ I subsequently saw a study showing that an ingredient called Glycylglycine decreases the size of facial pores but there hasn…
  • Greetings Groovy Goldfinger Gale! All these ingredients in this product are commonly used elsewhere in skin care so I don't see how they would pose any safety issue. It may make your skin feel a little greasy/slippery depending on how much dimeth…

  • I don't see any reason why this would be a problem.
  • Unless something has gone horribly wrong, there's no reason that adding a star ingredient at very low levels would cause any problem with the formula.
  • I'm sorry if I'm not being clear so I'll try to restate my position. Companies DO want effective products and formulators DO create "really good formulas." But formulators don't always need to use star ingredients at high levels in order to crea…
  • Polyquaternium-7 and 10 are the most common ones.
  • It's really hard for us to answer that from a scientific perspective because everyone's tastes are different when it comes to products (and because everyone's hair is different.) That's why we typically don't recommend specific products. Having said…
  • There FDA over the counter drug monograph doesn't specify any differences between adult and children sunscreen products.  I believe that people tend to use mineral based sunscreens on baby's because the ingredients are similar to those used in diape…
  • You can find all kinds of information on the internet. 
  • Interesting points, thanks!

  • First of all, the star ingredient is not always (not often) the ingredient that makes the product effective. You can have a very effective product and still advertise it based on an ingredient that does nothing.  Second, the formulators are not the …
  • The point is to draw attention to the "hero" ingredient to entice you to buy the product. 
  • Yes, I can see how double cleansing would be more effective. 
  • I'm not familiar with this product but in general home lasers are not as powerful as one's used by medical professionals. 

Howdy, Stranger!
