Low-porosity hair is very hard to style and maintain because it doesn’t allow water to penetrate the hair shaft. If you’ve been struggling to find the right products and ingredients for your low-porosity hair, you are not alone! It’s frustrating and challenging, and many people face this issue.
But there’s one super-ingredient that can actually be very beneficial for this hair type – glycerin! This powerful humectant retains and attracts moisture, thus leaving your hair hydrated and healthy.
Keep reading as we will dive into the benefits of glycerin and what it can do for your hair. We’ve also added a list of the best products containing glycerin.
What is Glycerin?
Glycerin (or glycerol), a coconut, palm, or soy oil derivative, is a thick and odorless liquid. It is a powerful humectant that helps retain and attract water to the skin and hair, thus effectively preventing moisture loss.
Aside from helping with moisture retention, glycerin has other benefits for the hair, like improving scalp condition and reducing dandruff, stimulating hair growth, and preventing frizz. Its use in cosmetic products has been recently reviewed by the American College of Toxicology and has been deemed safe to use.
- Sweet taste.
- No smell.
- No color.
- Environmentally friendly.
- Jelly-like structure at normal temperature – solidifies as temperature goes down and becomes liquid at high temperatures.
- Attracts moisture to itself.
Glycerin has been widely used in the beauty industry, but its sweet and jelly-like colorless structure has also found its purpose in the food industry, mostly as a food sweetener that has been FDA-approved.
Glycerin and Humidity
As miraculous of an ingredient as glycerin is, there are a few points to keep in mind when using it. Because it’s a humectant, it attracts moisture. If you live in a very humid climate, using glycerin will make your hair draw moisture in excess, leaving you with a fluffy, dry mess of hair.
Additionally, while low-porosity hair can benefit greatly from glycerin products, it isn’t recommended for those with high-porosity hair.
Benefits of Glycerin for Hair
Given its natural ability to literally pull moisture from the air, glycerin is widely used for skin and hair moisturizing. In fact, vegetable glycerin is the main ingredient of many humectants that have proven to increase and retain moisture on the top layer of the skin and hair pores.
In order to make sure the humidity and moisture are not only attracted but that it sticks to the skin and hair – glycerin is commonly used in combination with an occlusive- moisturizing agent that kind of forms a seal around the shaft and doesn’t let the moisture out.
However, studies have proven that the combination of glycerin and hyaluronic acid(another humectant) has positive long-term effects on the health of skin, hair, and human pores, even in the long run.
Ava Shamban, a board-certified dermatologist, explains that because it has small molecules, it can effectively penetrate and hydrate the cells of both the hair and the scalp, thus improving dandruff and dry and itchy scalp.
Why is Glycerin Good for Low Porosity Hair?
Aside from the much-needed moisture, low-porosity hair is highly unlikely to be able to absorb common natural oils, heavy oils, and protein treatments. And as such, their particle would only act as a shield and potentially may even cause build-up, further preventing the hair and scalp from breathing normally.
This is where glycerin steps in the picture. Its natural ability to attract moisture and retain it is perfect for the hydration of your hair which normally doesn’t want to get wet. In addition, glycerin-based hair products are widely popular for fixing damaged or dry hair.

All you need is some imagination, a spray bottle – and our simple tips on combining glycerin, oily, or butter-based ingredients and a scent that suits your soul.
In this list of ingredients, we’ll also include some DIY recipes that can greatly favor low-porosity hair.
Panthenol is a chemical for embracing hair growth and fixing dead split hair ends. However, it can dry out the skin, so ALWAYS use it with a strong glycerin base. According to Doctor Brendan Camp, a double board-certified dermatologist, panthenol isn’t only a great humectant and an emollient, meaning it can smooth out any imperfections of the hair shaft.
In combination with glycerin, you can restore moisture to your low-porosity hair very efficiently. But be careful not to overdo it, as you risk moisture overload, which can lead to split ends, limp hair, and breakage.
The amazing shea butter properties make the hair silky and smooth and provide enough nutrients. It has sealing properties, which, combined with the glycerin, will attract and lock in moisture in your hair. Shea butter is also rich in fatty acids and vitamins, so it can effectively reduce split ends, breakage, and dryness. You can add just a drop or two of glycerin oil since the shea butter is already greasy enough.
Grapeseed oil is a very lightweight oil that doesn’t weigh down or grease up your hair like other oils. Additionally, it’s an emollient, meaning it will soften your hair and hydrate your scalp. Grapeseed oil is also great for strengthening the hair shaft, reducing dandruff, and adding shine and moisture.
When coupled with glycerin, you have a powerful combination for attracting and retaining moisture in your low-porosity hair.
Aloe Vera Gel or Juice
Aloe Vera is an undisputed super-ingredient regarding skin conditions, but it’s also very beneficial for hair. Some of the benefits include strengthening the hair shaft, controlling grease, promoting hair growth, and protecting hair from UV damage.
You can easily make a very useful DIY conditioner with glycerin oil. Mix a big portion of aloe gel (you can even cut it out with your own aloe plant) and add around 15 ml of glycerin oil. Add a natural scent, or just let it be scentless and save it in a container. You’ll have enough conditioner for a week!
More beneficial ingredients for low-porosity hair include:
- Sea Algae.
- Slippery Elm.
- Flaxseed Gel.
- Castor oil.
- Marshmallow Root.
- Cetyl Alcohol.
- Glyceryl Stearate.
- Cetearyl Alcohol.
- Behentrimonium Methosulfate.
