Welcome to the Beauty Brains show. On today’s episode we’re going to be answering your hair care beauty questions! Hair products that claim to restore natural color in gray hairOuidad curl conditionerProducts that claim to thicken hairHow do you avoid hair damage?How do you know what ingredients actually do something?What are the best natural ingredients for hair products? Beauty Questions Bexaida asks – I have found this product that is restoring my hair color back to the shade I had in my youth , i used it for a few days and the silver and white turned darker and darker brown and my red undertones appeared as well . I use it less and less until all I need is once a week It is said to remove the Oxygen that builds up in our scalp as we age What do you know about this product? The product you’re referring to is called Hairprint. This uses a standard technology in which a metal is oxidized to create color. It can provide some gray coverage but it does not work in the manner which is described by their marketing. I was hoping you might take a look at the ingredients of the Ouidad Curl Immersion Triple Treat Deep Conditioner (see below). I had never tried a Ouidad product before due to price but finally caved after reading rave reviews about it. The problem is I really don’t like it and unfortunately can’t return it. I’m finding it doesn’t have much slip for detangling while it’s in my hair and when I rinse it out, it just doesn’t feel very conditioned. What is it about this product that would cause that? Also, is there anything that can be added to improve it? I’ve heard to add things like honey, oil, or glycerin. Thanks, Misty This is the problem with following online reviews. First, you don’t know if they are real or the people were paid by the company to write the reviews. And second just because a product works well for one person doesn’t mean it will be great for another. I like using hot water for shaving my face but it’s probably not a great suggestion for most people. Beauty product effectiveness is largely related to your personal preference and experience. So, you say that Ouidad leaves your hair without slip and it doesn’t feel conditioned. In looking at the ingredients they sure have a lot of ingredients!  There are a number of things in there meant for conditioning hair. Cationic surfactants like Behentrimonium Chloride, Cetrimonium chloride, and Stearamidopropyl Dimethylamine. Those should give slip but then there are also a bunch of things which can interfere with that like the shea butter, lanolin, the oils, even the glycerin. And they have silicones in there but Cyclopentasiloxane which tends to evaporate and the others are in there at low levels. Based on the ingredient list it is not surprising you’re not feeling conditioning. If you want conditioning as you describe look for something with Dimethicone high up in the ingredient list and something that doesn’t have as many ingredients to interfere with the working of all the conditioning ingredients. You also wanted to know if there was a way to improve it. Adding honey or glycerin will not improve things. I think that would make it perform worse. I’m not sure there is anything you can do but you might try using a leave-on conditioner after. That could at least improve your detangling effect.

Can you please explain the science behind this product? And can you explain what it means when the hair product says that it “thickens” hair? Thanks for taking the time to read this email. Nioxin prides themselves on creating products that thicken hair. They have some products in their line that contain Minoxidil so these are the basis for hair regrowth claims. Their other products “support” hair growth and work in standard product ways to make volumizing products like having a high level of surfactant and focusing on scalp cleansing. The reality is this is a marketing position and the product is unlikely to measurably improve hair thickness better than other products claimed to do the same. Tina says – I have Caucasian hair that seems to break off excessively and is almost always frizzy. The natural texture seems to be wavy and straight in different places. I don’t know what kind of shampoo and conditioner I should be using. Use a moisturizing shampoo and always use a conditioner afterwards if you are having problem with frizz and breakage. You might even consider using a leave-in conditioner. Hi Beauty Brains, I’ve really loved all your episodes on hair care recently, and listening to them helped me put my finger on what the core question is that I hope you’ll answer, which is “what are the best methods/products/etc to avoid damage to hair?” I like to grow out my hair quite long, so that means avoiding damage as much as possible so I can keep all the length I get. So how, in your opinion, do I do that? This is where all my other major questions spring from. Does harsh shampoo really cause damage? What conditioning ingredients really help? What deep treatments help? Where’s the balance between moisturizing your hair and getting hydral fatigue? On that note, what about the air drying vs. hair dryer debate? There’s a lot of conflicting info out there on the internet on these topics. If you guys can put together a top ten tips to minimize damage or similar I would really love to hear it! – Thanks Elizabeth Tips for minimizing hair damage. Minimize washing. Getting hair wet swells the fiber and causes damageDon’t color your hairDon’t use a curling iron or flat ironAlways use a conditioner – preferably something with siliconesMinimize combing and brushingMinimize the use of things in your hair like scrunchiesDon’t get a perm or relax hairProtect hair from the sun if you’re out a long time My name is Sophia. I’m obsessed with not damaging my hair because I literally put hundreds of dollars into it. My friends tell me that hair dye is fine but I’m not so sure. As a cosmetic chemist you would know, just how much damage does hair dye cause? And even if I only do it once, what effects would that have and how would I recover from it? Thanks! Well, we just talked about hair damage and coloring your hair is one of the most damaging things you can do. The only thing more damaging is relaxing hair which actually breaks protein bonds in the hair fiber. If you only do it once, you can recover from it. The new hair that grows out won’t have any of the same damage problems. Of course, it can take a long time to grow back. Hair grows about half an inch a month. Question: We often see companies marketing a product with a certain ingredient and stating this ingredient provides you with this benefit like for example a hair cream with Shea Butter and coconut oil marketed as heat protecting cream, or a Cinnamon hair mask marketing that Cinnamon helps with hair growth. With so much miss information out in the internet where can we as consumers find if these ingredients actually provides what there stating?  (Jeanie) There is no single source – although the Beauty Brains is a good place First assume that things don’t work. Most things won’t. Journal of Society of Cosmetic Chemists Google Scholar Cosmetic Chemists on Twitter Next time Thanks for listening.
