  • Hello - I don't believe it has been studied in direct comparison but the few papers I read suggests that it works just as well but is a little less damaging to skin. See this description here https://www.dropbox.com/s/9eeyjjxtb6tkvs2/sugaring.pdf?d…
  • You can apply coconut oil to unwashed hair and it will still have a conditioning effect. Of course, the more things in your hair, the less of an effect you should expect to get. It would work best on clean hair, but it will still work otherwise.
  • These things are not exactly a scam but they probably aren't going to work in a noticeable way either. Hyaluronic acid is a humectant which means it will give you some moisturizing. However, there is little evidence that moisturizing a scar will do …
  • I think there is just a general warning to not spray products directly into your face. The company is just being extra cautious because sunscreen sprays are technically not allowed according to FDA regulations. Pretty much any standard sunscreen sp…
  • 1. I'd choose the less expensive product. Neither of these are measurably "healthier" or "more gentle" for hair. 2. I don't know what you mean by "performs better". I doubt you will notice much difference between castor oil and mineral oil in th…
  • The ScienceyHairBlog article is a little more optimistic than I'd be based on the available science but they mostly get it right. The post from the Beauty Brains on Coconut oil was from April 2014. I haven't seen anything new from Dove on the subje…
  • No, Vitamin C is not pro-oxidant. Vit C (Ascorbic Acid) oxidizes to Dehydroascorbic Acid which is a stable molecule. It will not react further under normal circumstances. https://en.wikipedia.org/wiki/Dehydroascorbic_acid Of course, the reality i…
  • Well, to be fair there are probably ingredients that raw material suppliers sell which they've demonstrated under lab conditions can make blonder hair last longer. I'm just saying there is nothing that you could use in a product that would make any…
  • There is no evidence of which I'm aware that exfoliating your scalp will have any beneficial effect.
  • With all due respect to the chemist they consulted, there is no evidence that a keratin infused product will cause your hair to break more no matter how much you use. The bottom line is that you do not have to worry about overdosing your hair with …
  • Here's their ingredient list. Aqua, Sodium Laureth Sulfate, Sodium Lauryl Sulfate, Cocamidopropyl Betaine, Sodium Chloride, Cocamide MEA, Parfum, Silicone Quaternium-18, Glycol Distearate, Benzyl Alcohol, Guar Hydroxypropyltrimonium Chloride, Tride…
  • Color lines are really just a marketing gimmick. They have less detergent so they aren't as stripping but you're unlikely to see much difference between using a color product line versus a normal shampoo. Lines for specific colors have some techn…
  • Thanks! @magicscalpel
  • Silicone in skin care is not dangerous. They are perfectly fine, effective and safety tested ingredients. Silicones are also not comedogenic. It makes sense that the product works well for you.
  • I would point out the following... When using any treatment 3 things can happen. 1. The condition gets better 2. The condition gets worse 3. The condition doesn't change This is exactly what can happen when you use no treatment. The fact that…
  • It could be that it makes the product feel more slippery when using it. I don't think this is a good idea because it could harm skin and there are better ways to do that, however, that would be my guess for the high pH.
  • Mexoryl can be found in La-Roche Posay sunscreens as you said. http://store.skincarelab.com/anthelios.html Cell-Ox Shield is just some made up term for a technology that sounds impressive. I'm not sure if they removed the Mexoryl from that formula …
  • Triethanolamine is used to raise the pH. However, that doesn't mean that the overall system will be basic, just less acidic. Typically, synthetic detergents are used in systems that have a pH 5-6 for skin products. pH does not have much impact …
  • Soap is more harsh as it can be more drying and irritating to skin. SLS and SLES are more efficient detergents however so in that sense, they are more stripping. Overall, you'll have a better experience using synthetic detergents versus soap for bo…
  • I would guess that formula is slightly acidic. Especially since they are using Potassium Sorbate as a preservative. It is only functional as a preservative at a pH of 5.0 or less. While Magnesium ions are one of the components for hard water and t…
  • You would likely be increasing the chance of some kind of microbial contamination. Perhaps if you dried out the flowers but adding anything like that would reduce the shelf life of the product.
  • Head and Shoulders would be a good place to start.
  • Could you provide a list of ingredients? Most likely another L'Oreal formula is pretty much identical.
  • Tetrasodium EDTA can be used in acidic environments too so that is no indication of the pH of your shampoo. It's most likely slightly acidic but I'd need to see the rest of the ingredient list to make a better guess.
  • There is never a simple answer like "avoid this ingredient because it causes dryness". You do not buy ingredients, you buy formulas. A suitably trained cosmetic chemist can take almost any ingredient and formulate with it in a way that mitigates th…
  • @Doffy90 - It's just time. Other projects have become more pressing.
  • For your hands, your best bet is to use something that contains Petrolatum. It will be a much better moisturizer than other oils. This could also work for your face but it might feel too heavy.
  • @halfpintpete - Thanks for the kind words! And also thanks for joining the course. Feel free to contact me if you have any questions along the way.
  • Yeah, I don't have much of a routine either. I mean, I use shampoo as both shampoo and body wash (and facial wash). And I shave usually only using hot water. I do use sunscreen pretty regularly.
