Homemade Mint Shaving Cream: A Simple DIY Recipe Tested Against Store-Bought
Fresh mint is one of those plants that tends to take over a garden once it gets established. A few years ago, I planted mint in my garden, and now it comes back every year with more vigor than my family could ever use for tea or cooking. So I started wondering: could I use it for something completely different?
In this experiment, I decided to harvest fresh mint from the garden and use it to make a homemade shaving cream. Then I put it to the test side-by-side against store-bought shaving cream to see how it performed.
Why Mint?
Mint has several properties that make it an interesting ingredient for shaving cream.
First, mint contains menthol, which activates the cooling receptors on your skin and creates that familiar cooling sensation. For example, cigarette brands have used menthol to reduce the perceived harshness of smoke. That cooling effect made me think mint might help reduce the burning or irritated feeling that sometimes comes with shaving.
Mint also contains mild astringent compounds, including tannins and phenolics, which can slightly tighten the skin. In addition, mint has some antimicrobial properties, making it an appealing natural ingredient to experiment with in a shaving product.
When I shave, my face can sometimes feel irritated, burned, and bumpy afterward. So the idea of a shaving cream that cools, refreshes, and possibly tightens the skin seemed worth testing.
A Quick Note on Menthol
I also happen to have a jar of menthol crystals that I bought several years ago. When I first got them, they were small pellets. Over time, they sublimed and gradually formed long crystal growths. It is a fascinating reminder that menthol is a very active compound with some unusual physical properties.
How Store-Bought Shaving Cream Works
Store-bought shaving cream is actually fairly engineered. Many commercial formulations use fatty acids such as stearic acid, combined with a base, to create a dense, stable foam. Aerosol versions also use propellants to dispense the cream from the can.
I wanted to see if I could create something much simpler using ingredients I already had at home, while adding fresh mint from the garden to create a unique shaving experience.
The Simple 4-Ingredient Recipe
Here is the base recipe I used:
- 1/2 cup liquid Castile soap
- 1/4 cup glycerin
- 2 tablespoons coconut oil
- Fresh mint leaves, crushed with a mortar and pestle
What Each Ingredient Does
- Castile soap creates foam and helps cleanse the skin.
- Glycerin helps stabilize the foam so the microscopic bubbles do not collapse too quickly.
- Coconut oil improves lubrication so the razor glides more smoothly over the skin.
- Fresh mint leaves add cooling, aroma, and a unique skin feel.
How I Prepared It
I mixed the Castile soap, glycerin, and coconut oil together ahead of time and stored that as a base. When I was ready to shave, I took about a tablespoon of the pre-mixed base, crushed fresh mint leaves with a mortar and pestle, added the base to the mint, and then whipped everything together with a shaving brush until it formed a thick green cream.
The result was a fresh-smelling shaving cream with a distinctive green color and a texture that looked surprisingly usable.
Side-by-Side Test: Homemade vs. Store-Bought
To find out whether this was just a novelty or something that actually worked, I tested the homemade mint shaving cream side-by-side against store-bought shaving cream.
The first thing I noticed was the smell. The mint cream smelled amazing—fresh, clean, and natural.
In terms of performance, the glide on my face felt just as good as the store-bought cream, and possibly better. I could also feel a distinct cooling sensation on the mint side, along with a slight tightening of the skin. That combination made the mint side feel especially refreshing.
One concern I had was that fragments of mint leaves might clog the razor. Surprisingly, that did not happen. The razor handled the homemade cream just as easily as the commercial product.
Cleanup was also easy. The homemade mint shaving cream rinsed off my face just as well as the store-bought version.
Final Thoughts
This homemade mint shaving cream definitely worked. It provided good glide, rinsed off easily, smelled fantastic, and added a noticeable cooling effect during shaving. The slight tightening sensation from the mint made the experience feel even more distinctive.
If you already grow mint in your garden and have more than you know what to do with, this is a fun and surprisingly practical way to use it.
Sometimes the best experiments come from looking at an overgrown plant in the garden and asking, “What else can I do with this?”
