Glycerin is all the rage these days. If you read the label of the majority of curly hair products, chances are glycerin will be listed in the top ten ingredients. In this post I’m sharing Everything You Need To Know About Glycerin And How It Affects Curly Hair to help you understand this commonly used ingredient and how it plays a role in your curly hair care.
Early on in my curly journey, I read a few posts floating around about the affects glycerin has on your curls.
As a new curly girl, it seemed to be too in-depth for me to wrap my mind around since I already felt overwhelmed by all the information surrounding the curly girl method.
Speaking of feeling whelmed about the curly girl method……..
If you are currently trying to follow the curly girl method and feeling a little overwhelmed, I created a special gift just for you. Because curly girls stick together <3
With the overwhelmed curly girl in mind, I created a simple cheat sheet that helps you break down and simplify the method.
I create The Curly Girl Cheat Sheet just for you. In printout, I break down the method step by step to help guide you along the way.
After six months of seeing a good amount of success on my curly journey, I started to notice a change in my hair. As fall turned into a cold depressing winter here in PA, my hair started to lose moisture by the hour.
I would style my hair the same as I did months ago and it would look great but with each passing hour, it became more and dry. My curls were almost starting to go limp.
I spent a good amount of time researching what could be the cause and all roads lead to glycerin being the culprit.

What Is Glycerin?
Glycerin is a simple polyol compound. It is colorless, odorless, and non-toxic. It is used as humectant in pharmaceutical formulations.
Glycerin can come from multiple natural sources because triglycerides can be derived from animals or vegetables. Some examples of vegetable sources would be coconut oil and shea butter.
So when it comes to your curly hair products, glycerin is used as a humectant.
A humectant is a hygroscopic substance used to hold in moisture.
Humectants are frequently used in cosmetics as a way of increasing and maintaining moisture in hair care products including shampoo, conditioner, frizz serum, and more.
The Good, The Bad, And The Ugly Truth About Glycerin
The Good: Essentially glycerin is a humectant that works to take moisture from the air and deposit it into your curls thus holding in moisture.
Sounds like a curly girl’s dream, am I right?
The Bad: What they don’t tell you about this amazing ingredient that magically takes moisture and adds it to your curls is that it will ONLY do so when the environment allows it to.
That is where dew points come into the picture.
A dew point measures the amount of moisture in the air. The higher the dew point, the higher the moisture content of the air at a given temperature.
Let’s break this terminology down into curly girl lingo….
Depending on the dew point in your geographical location will depend on whether or not glycerin will have good or bad effects on your hair.
Do you feel a little confused? Because I certainly did.
Let me break this down a little further for you so your brain doesn’t hurt…..
There are high, medium, and low dew points.
Keep in mind that glycerin works to pull moisture out of the air and put it into your curls.
At a high dew point, using products with glycerin can add too much moisture into your hair and make it super frizzy.
When the dew point is in medium range, glycerin typically does really well adding enough moisture from the air into your curls.
But when the dew point is low, it can have the reverse effect and rather than add moisture from the environment into your hair, glycerin actually takes moisture from your hair and puts it back into the environment.
Pretty crazy right?
This explains why so many curly girls struggle to keep their curls happy in the winter.
The air is already dry then to top it off we are using products that are sucking the moisture out of our hair and putting it back into the environment.
As always with curly hair, everyone’s hair is completely different. Some people have no problem with glycerin and can liberally use products containing it in any dew point. While other curlies struggle to keep moisture in their curls.
Especially in the winter months.
The Ugly: naturallycurly.com says “Many heat-styling techniques can generate sufficient heat to boil the water inside the hair shaft, which can cause terrible breakage.
One way to prevent or minimize this problem is to coat the hair with an emollient that seals in the moisture and that does not transfer the heat from the appliance to the hair as readily.
Unfortunately, glycerin conducts thermal energy pretty efficiently (it transfers heat readily to the hair), especially when compared to silicones, proteins, and polyquaternium conditioning ingredients.
For that reason, use glycerin sparingly and in combination with a more insulating and protective moisturizer when using any sort of heated drying or styling treatments.”
How Do I Know If My Hair Is Sensitive To Glycerine?
Warning signs that your curls may have a glycerin sensitivity are…..
- Excessive frizz
- Losing moisture quicker than normal
- Halo frizz
- Limp Curls
How To Care For Glycerin Sensitive Curls
Go Glycerine Free For 30 Days
If all roads lead to your curls being sensitive to glycerin, it’s time to go glycerin free for a while.
Don’t get me wrong, glycerin is not the devil. It has many amazing benefits.
But if you think it’s the culprit of your halo frizz, then it’s time to do a little experimenting to pinpoint what the cause is.
I recommend going glycerin free for 30 days, then slowly start incorporating back into your routine.
Keep A Daily Journal Of What Works And Doesn’t Work For Your Curls
If you are part of the large community of curly girls that have glycerin sensitive curls, it is imperative that you keep a detailed log of everything you put in your hair.
All you need is something to write on or something to write with.
But early on in your curly girl journey, make a habit of documenting how your hair responds to different products, treatments, and techniques.
As mentioned above, so many things play a role in how your curls are effected by what you use down to the very dew point in the weather.
Use the image below as an example of what you need to track each day. It will enable you to know exactly what works and what doesn’t work for your curls.

NOTE: It’s important to remember that not all curls are the same. What works for your hair, may not work for mine.
That is why it is so very important to test different products and techniques and to be diligent in tracking what you are using and adjust accordingly. Check out this helpful post on how to track your curly girl journey.

I want to first say, thank you for all your helpful posts and information! My curly girl journey has been a long process of trial and error. I have 2B-C wavy hair with some 3A curls (sometimes); low porosity; low to medium density; fine hair. I had been using the SheaMoisture products but after following you and several other Curly community ladies, I’ve realized that they were the wrong products for me. I’ve always had issues with major frizz; both wet and dry! After watching Courtney’s videos and reading your blog posts, I’ve decided to cut out glycerin to see if that is the culprit. I’m also trying to avoid coconut as it seems to dry my hair out. I realized that I was also lacking protein and after switching products, it seemed to get better. It’s hard to find good products that have neither glycerin nor coconut but I’ve been researching all the most popular companies and compiling a list.
The Giovanni Tea Tree Triple Treat Shampoo you listed above (and in Courtney’s video) does, in fact, have glycerin in it and Courtney does put a note in her video saying she goofed. Curl Junkie has a selection of products that are glycerin-free as does Curls brand. I haven’t tried either of those brands yet, but they are next on my list. I just tried the JessiCurl products and I’m not certain my hair likes them. I have major frizz again – could be that the JessiCurl products don’t have protein in them?!
Thanks again for helping us wavy/curlies out here trying to navigate the rough waters of products!
