How do you make your own pre-shave oil?
A simple DIY pre-shave oil recipe and what's really in a premium bottle — usually just carrier oils like castor, grapeseed and squalane, plus how to use it.
Here's the open secret: most pre-shave oils are simple blends of common carrier oils — often castor oil for slip plus a lighter oil, sometimes a few drops of essential oil for scent. That's why a $35 bottle can feel hard to justify. You can mix a comparable one at home in minutes. Here's what's in it and a basic recipe.
What's actually in pre-shave oil?
Read the labels and you'll see the same building blocks repeat:
- Castor oil — thick and slick; the “glide” ingredient in many pre-shaves.
- A light carrier oil — grapeseed, sunflower, jojoba, or squalane to thin it out and absorb cleaner.
- Sometimes essential oil — a few drops for scent (e.g. sandalwood, tea tree).
That's usually the whole formula. It's not exotic chemistry — which is the point: you're often paying for branding, not rare ingredients.
A simple DIY pre-shave oil recipe
A common, easy starting blend:
- 1 part castor oil (slip)
- 3 parts light oil — grapeseed, jojoba, or squalane (absorbs cleaner, less greasy)
- Optional: 2–4 drops of a skin-safe essential oil per ounce, for scent
Combine in a small dropper bottle, shake, and adjust the ratio — more castor for more slip, more light oil for a lighter feel. Patch-test any essential oil first if your skin is reactive.
DIY oil vs a glycerin pre-shave serum
One thing you can't easily DIY is a glycerin pre-shave serum. Oils are occlusive — they sit on the surface. Glycerin is a humectant that pulls in water for a lighter, non-greasy slickness, and turning it into a stable serum takes proper formulation, not a kitchen mix. So if you want the oily route, DIY is cheap and easy; if you want the lighter humectant feel, a ready-made glycerin serum is the practical option. See what glycerin does and do you need pre-shave oil?
How do you use it?
- Shave after a shower or warm the face.
- Massage a few drops into damp skin.
- Lather over the top and shave with light pressure. A little goes a long way — too much fights the lather.
And remember: a slick soap already does most of this job, so a pre-shave (DIY or bought) is an optional booster. For the soap, see best artisan shaving soap.

Can you DIY a glycerin pre-shave serum?
Not easily. Oils are occlusive and simple to blend, but glycerin is a humectant that needs proper formulation to become a stable, non-greasy serum. If you want the oily route, DIY is cheap and easy; if you want the lighter humectant slickness, a ready-made glycerin serum is the practical choice.
How do you use pre-shave oil?
Shave after a shower or warm the face, massage a few drops into damp skin, then lather over the top and shave with light pressure. Use only a little — too much fights the lather. Remember a slick soap already does most of this, so pre-shave is an optional booster.
