[@SwavyCurlyCourtney]

Hey guys! I sure hope you are as excited about this series as I am! Haha I go full Sciency Courtney on different categories of ingredients in your hair care. Please comment down below what other categories you like for me to talk about. 👇

[@rosewolfe92]

I would like to hear more about chelating agents, and ingredients that provide hold / prevent frizz (I don't know what category that is). On a general note: when I started the curly girl method (about 3 months ago), I decided all these ingredients are just too much to keep up with. At this point, however, I am keeping an ingredients list with all different types of ingredients and their function. Now I got to add a bunch of new information and am a bit more knowledgeable than I was about 30 minutes ago. Thank you so much for taking the time to sort out your knowledge and information, and present it in a way that is such a joy to watch! I really enjoy your videos. There is something about the way you talk that makes you so real - like you are the girl living next door. I don't think a lot of other youtubers have that, so definitely keep on doing what you are doing!

[@blacklabgoldens8197]

could you make a video about deep conditioners and how their ingredients are different than normal conditioners and why the deep conditioners do what they do? (I hope that made sense😂)

[@herhcollins5637]

coukd you share your konwledge about what ingredient will.help keep the moyigize on the hair? my hair.only keep nice for an hour and become.very frizee all the rest time.

[@thebitchycrafter339]

Here's the link I'm sure you just forgot in all your excitement to get this posted. science-yhairblog.blogspot.com/2016/07/shampoos-which-remove-product-build-up.html

[@crystalburkhalterpolizzi1108]

As a dual degreed molecular biologist, this video made my heart really happy. My husband is a chemistry professor, and he even enjoyed listening to it while I got ready for work! Double thumbs up from us!

[@SwavyCurlyCourtney]

That is awesome! That really really makes me happy!

[@blacklabgoldens8197]

Courtney this is one of the many reasons why I love your channel so much! us science girls want to look good and know why the products work:)

[@ozarks_onna]

Seeing Courtney's smiling face surrounded by chemical names was an image I did not know I needed until today.

[@pagetofil7819]

As a sciency girl myself, I love when you delve a bit into the science behind the products - it really helps me know what to look for in my products

[@alyssajoy08]

I use a website called "is it curly girl" and you can copy and paste in an ingredient list. It will tell you what each ingredient is and if that ingredient is curly girl approved so you can decide what you are comfortable with. Very helpful website

[@christopherdelacrouse8415]

Probably the easiest video to understand with regards to ingredients in hair products. I've been confused for months now and after watching this video I can freaking understand some things a lot better thanks 👍🏽

[@slayer8427]

I am already exited for this videoclass !

[@lisser7]

This was so helpful, I added it to my “saved” videos list so I can reference it often. Thank you for taking the time to put it together!

[@SwavyCurlyCourtney]

I'm so glad!

[@johnsonfamilynaturals]

I don't use any sodium lauryl sulfate in anything, it can cause lots of problems😬. Not just outward but inwardly.

[@myrahuber260]

I should've known better and next time I'll peek first. 🤦 I totally was pausing the video and taking down notes not remembering that Courtney is the type of person to list them for me in the description! Thanks Courtney! 🙂💜🦉

[@googlespyfranchise9089]

Brilliant vid Courtney! Thanks for all your efforts

[@misslazydaisy80]

Just wanted to say that I found this video to be the most helpful of all the videos of yours I have watched so far. Thanks for covering this so in-depth!!!!!

[@simonettasaccon3262]

I would love to see a video about emollients! In particular the differences between “natural emollients” like butters,oils, and silicones, and why the first ones are considered to be better, do they work differently? I really hope it makes sense, science isn’t definitely my field😂🙌🏻

[@QuinceyG]

I am sooo happy I found this channel, and find if so endearing how much you know, and care for your curly hair. I am a feel is fine curly girl, and have STRUGGLED so much with products and styling. Nothing worked, or the products always were either too much for my hair or not enough. UGH! I feel upon one if your videos re: co washing last week, and heard you speak about the As I Am co wash, and was intrigued. I’ve spent, and wasted, SO much money on products and was convinced that the co wash would also fail me, but since it is cheap I figured I could waste the 8 bucks, lol! WOW! My hair was sooooo easy to style and mange for 3 to 4 days this week, and I used it again in wash day the other day, and I’m also experiencing the same results. As a styler I use the Innersense I Create Life Fisk, and a touch of the Innersense leave-in, and now I love the products when I thought they were not working. I did not realize how much my curls needed the As I am hydration, and I am floored, LOL! Thank you so much for your knowledge, and I need the learn so much more from you. :) Especially regarding of my hair needs treatments or protein? I am so glad I found your channel. -Quincey

[@katereilly3826]

Thank you so much for this Courtney! I'm about 3.5 months into my curly journey, and I'm just starting to wrap my brain around reading labels and recognizing ingredients. This helped a LOT! I am so excited for the rest of this series!

[@cathismith2624]

I'm 7 months in, and only just discovered that every product that I have ever used has high amounts of glycerin in them - and now discovered that my hair hates glycerin and it adds to the frizz..... So now I have to stop being lazy and really learn all of this science stuff...... 🙄.

[@SwavyCurlyCourtney]

You're so welcome!

[@kristinapettus8371]

I have to admit that chemistry isn't where I thought you would nerd out. Once again, you make things easy to understand!

[@mollymoench9018]

This is *extremely* helpful. Somehow more accessible than others I’ve tried to watch on the same topic.

[@alyssajoy08]

Please continue this series! It's so helpful!

[@amywilson7288]

Just came across your page, and it's so helpful! I'm a teacher and would always straighten my hair with a flat iron on work days. Summer is a perfect time for me to try this out, and I just ordered some products to give this curly girl method a fair shot! Thank you so much for all of the helpful videos! In the past couple of days I've watched quite a few! Can't wait to get my products and see what happens during this first month.

[@brendaoquin]

I would love a video on types of glycerin. Like, is glycol a glycerine? I see a lot of different types of glycols in hair products but can’t find if they’re a glycerin.

[@ericablair3222]

Thank you for creating this series!

[@WafflesChowder]

Tresemme has come out with some silicone and sulfate free products. You should try them

[@slayer8427]

Great content ! Gonna watch a couple of times

[@stefanieblanche2748]

This video is really amazing Courtney! Now I understand surfactants! Thank you!! Is the Sodium Lauroyl Methyl Isethionate also anionic? You should try the Briogeo Scalp Revival Shampoo it has two anionic surfactants Sodium Cocoyl Isethionate and Sodium Methyl Oleoyl Taurate in it and exfoliating beads plus bentonite clay. I really like it for a deep cleanse its very good for my oily scalp. Also love the Curlsmith Detox Shampoo very much makes my hair so soft and shiny

[@oliviashafer1435]

Is there a way you can make a categorized list for us. Maybe on your website. So we can snap a screenshot for shopping reference

[@yensid4294]

I didn't think co-washing would work for me at all but I ran out of shampoo & only had a 3 in 1 cowash product around so I tried it. Best hair day I've had in weeks! I am now going to experiment with alternating cowash & cgm approved gentle shampoos.

[@Elizabeth_Lucy]

This was wonderful!!!!!!!! Please make more like this!!!

[@victorialovatt976]

*pauses video and runs off to check shampoo/conditioner hoard* “Ah ha! Just as I suspected!” 🤣 Thanks for this info Courtney (and the list....just spotted that now I’ve written all over my desk)

[@cathismith2624]

Ditto - I kept pausing it to write them all down!!

[@SwavyCurlyCourtney]

Happy to help!

[@valerielinares2068]

I just started my hair journey. I am so excited for my dry, damaged hair to become healthy and happy!

[@laurac445]

i need to know about this. thank you!

[@SwavyBlonde]

Thank you Courtney, that was so useful. I had to say several times to my fiancé to stop talking to be because I wanted really focus on this video lol :D

[@arlynch.jimenez3543]

Great content!! Thanks so much for sharing these amazing information, I really enjoyed. I wonder if you can make a video about humectants. I live in a rain forest (I'm from Costa Rica😅) and it's kind of difficult to deal with frizz, I know I have to avoid glycerin went it's raining season, but I don't know what ingredients can replace it. Thank so much once again for this video.

[@cathismith2624]

I've discovered that my hair hates glycerin and have no idea how to replace it either 🤔

[@adriannajauregui8816]

Man ooh man!!! I have a thing for the nerdy side of things. Right up my ally. 💋

[@larimarfondeur7847]

Will olefin sulfonate clean even non soluble silicones like dimethicone? Or do I need to use a sodium Laurly/laureth sulfate ? Is it bad to use a Leave in conditioner with dimethicone in it for a week before washing? Would love to hear your take on this

[@SwavyCurlyCourtney]

I have not personally found any studies that show that Olefin Sulfonate removes dimethicone. I know sulfates do remove it though.

[@SudsBees]

I formulate my own products and beginning to formulate products for my fine curly hair. This video was so informative for curly hair friendly surfactants ❤️❤️. Now off to formulate, hoping I don't have too much product loss during testings 😂

[@valerielinares2068]

Back in college, I destroyed my hair because I didn't realize how stripping clarifying shampoos are. I used to use it every time I washed my hair. It ain't good. It ain't good at all. Once I realized, "hey, I'm not supposed to use clarifying shampoos all the time cause it will strip my hair," I stopped using it. Don't do that. It's not good. Lol! Seriously though.

[@TomPettyAsFuck]

I love your videos. When it comes to wavy hair, I need someone to ELI5 and you do just that. I know you've done a video on NYMs Curl Talk line, but I was wondering if you have tried the NYMs Naturals Tahitian Gardenia Flower and Mango Butter curl line? If not, and anyone else besides me is interested, could you possibly do a one brand wash day with it? I'm really curious if it would be good for wavy hair

[@katereilly3826]

Ditto!

[@juliebruce1114]

I use it (3b/c medium porosity) and I love it in the winter here in Indiana. My daughter tried it (2B medium porosity) and she loves it too! I just can’t use it in the summer because our humidity is so high. We both also have fine hair.

[@rebachick94]

Watching you read the ingredients list was the best part of this video.

[@SwavyCurlyCourtney]

Glad you think so! HAHA

[@RebeccavanDorsten]

My hair does not like olefein sulfonate at all.. I actually prefer ammonium sulphate somehow that’s more gentle on my hair even though it’s not curly girl safe..

[@Rasp100]

This was just perfection Courtney, thank you !

[@SwavyCurlyCourtney]

Glad it was helpful!

[@rebeckajohnfors4972]

Awesome video!!! Loved it, please do more about other ingredients and if you want to do a part 2 and rant on more about surfactants then please do, I want all the information and could listen to//watch you for ours

[@SwavyCurlyCourtney]

Great suggestion!

[@TheHolmeOvergaard]

Hi Courtney 😊 Is it me, or do I not see ‘sodium Cococeth Sulfate ‘ in your list? Do you know this? And is it too stripping? Thanks in advance 👍🤩

[@tomas-yourhairguru4588]

Just wondering, could I read the articles you have gotten all this information from, I am curious to do research on the "Magnetic Build Up" Just never heard of this before

[@tomas-yourhairguru4588]

Also low porosity hair, tends to be very hydrophobic, and rejects most products, so I am surprised that your experiencing buildup if your saying your hair is low porosity.

[@kate7621]

Great info presented well. Thank you

[@kelwrg]

I loved the part where you talked about the difference between the surfactants.

[@SwavyCurlyCourtney]

Thank you! I am glad it was helpful and interesting!

[@LauraRose109]

I would love to see a video on water soluble products! I belong to a curly girl support group on Facebook and it seems like every post has a comment that products won’t work on your hair unless they are water soluble. It also seems like there are only a few brands that have these kind of products, too. I’d love to know more about that. Thank you for your informative videos!

[@cathismith2624]

I ended up ditching the 'purist' Facebook groups as they were so strict on hair rules...... Have a look on Instagram for how different curly girls have had to modify the method to suit their hair needs. It literally saved my hair and my sanity!! 🥰

[@abby14mimi]

Thank you 🙌 superb information worth sharing for ❤

[@hanabadawi816]

Hey! So I was just bingeing your channel, all about curls and the curly girl method, as I am thinking about starting it for myself, however, I do have a question. Before you started CG, when you washed your hair and let it air dry, would it look the same as when you do the CGM and let it air dry. It's a question that I'm very curious to know... :) Love your channel btw, it gave me a lot of insight

[@alexisrushlow9036]

Soooooo excited about this!

[@TheMissikissa]

Really love Sicence-y Nerdy Courtney Content, more please!

[@thebitchycrafter339]

[@juliebruce1114]

Thank you so much! You give a lot of information but you explain it well so I don’t get dizzy 🥴 Unfortunately I’ve found that on other channels.

[@SwavyCurlyCourtney]

Glad it was helpful!

[@juliebruce1114]

Usually are! And so much fun🥰

[@trentkatelas4707]

This video has been helpful. I have been slowly going into the curly girl method over the past year or so. With surfactants its scares me alot to give up my trusted soduim loreal sulfate as i get a greasy scalp that leads to itching if not regularly removed. What are some actual curly girl surfactants ingredients should i look for that will help as i am really looking into surfactants now that i ditched all silicones (best decision i have made for my hair).

[@HennyStruik]

The number of surfactants in a shampoo isn't important because In general the total percentage of surfactants in a shampoo doesn't exceed 30%. A manufacturer can put 10 different surfactants in a shampoo, without being more harsh than a shampoo with just one surfactant in it.

[@natashaj111]

Hi Courtney out of the products you mentioned - which is more moisturizing Treluxe or Inahsi?????

[@jacquelineargueta1438]

Hi! I love you hair! I feel like mine has potential to look like yours one day if I follow the curly girl method. I just wanted to know if you recommend the Raw Sugar line sold at Target? I read the ingredients for them and it seems they contain a lot of alcohol, usually in the first 5 ingredients and sometimes more than 1. That seems harsh to me but I'm not an expert so I was hoping you could give me some guidance? I am in the market for a new hair care routine.

[@angelat2917]

I have hair like you! You are such a teacher for me. :-)

[@paulakittyodriscoll999]

Loved the info ❤

[@rachelweishaar6085]

Has anyone referred to you as the Alton Brown of Wavy Curly hair yet? I appreciate all your work!

[@isabellathomas3743]

Exiting!!

[@gigig7713]

Courtney, have you tried Hair Story New Wash?

[@chelseapickslay5359]

So helpful!

[@SwavyCurlyCourtney]

Glad it was helpful!

[@sillyelliie8663]

So excited

[@supunratnayake1572]

You should make a video on gelatine protein treatment Courtney 😇

[@AthenaPadilla]

You're doing great on your channel.

[@SwavyCurlyCourtney]

Thanks! You too!

[@oliviashafer1435]

Your hair has gotten longer these past few mos!

[@bethelight6230]

Hi Courtney!! Love your videos always! Regarding your recent statement, it is imperative, in this education that you've undertaken, that you watch this video of YoungRippa. It won't take long, and its vital to what's really occurring. Love and prayers always to you, and my fellow wavies❤🙏🏻 Here: kzbin.info/www/bejne/qJXTenyfd8pqjcU

[@corrinamarie454]

You could at least give credit to Science-y Hair Blog in the description box, considering that you posted her list of anionic surfactants (with her commentary) almost verbatim from her site. Plagiarism isn’t a good look and I’ll be informing Wendy of this in case she chooses to take action.

[@mitzaline]

She gives loads of praise and credit in the video.

[@corrinamarie454]

mitzaline but did you know that the text in the description box was written by someone else? There’s a reason sponsorships are required to be noted in both the video and the description box-because people don’t always watch full videos or open description boxes. It would take zero effort to note that the list (including all of those parenthetical comments) was taken directly from someone else’s work. I’m not sure why this is such a radical concept to people.

[@thebitchycrafter339]

I'm sure she just forgot to post this link. A slip of the mouse button, you know, in all the excitement. Don't worry, I found it and dropped it a few places. science-yhairblog.blogspot.com/2016/07/shampoos-which-remove-product-build-up.html

[@savannah1311]

@@corrinamarie454 If you watched the end of her video she did actually say she is going to link a bunch of Science-y Hair Blog's articles in the description box below, which she didn't, which shows she most likely just forgot to include the link. If she said it in the video it was most likely an accidental oversight not her trying to pass of the work as her own.

[@corrinamarie454]

Savannah it’s now been almost a week. If it was a simple oversight it should have been corrected. The text is an almost verbatim replication of a 2016 blog post. I don’t know about anyone else, but I knew by the time I was in middle school that it was necessary to cite sources, especially when directly copying/quoting. This was the first video I ever attempted to watch by this individual, and I refused to finish watching it after seeing the description box. If she cannot address and correct an “oversight” after a week, then I get the impression that she has no desire to do so.
