9 Rules to Follow When It Comes to Natural Hair Oils (What Actually Matters)

Here’s the truth: most natural oils overlap in what they do. And just because an oil works beautifully for someone else doesn’t mean your hair will agree. Over the years, these are the rules I follow to keep my hair healthy, soft, and growing—without an oil collection that looks like a beauty supply store aisle.

Rule #1: If it works for your hair, stick with it

Hair doesn’t care about trends. If an oil consistently keeps your hair moisturized, soft, and strong, that’s your oil. No need to cheat on it.

Rule #2: Glycerin oil is powerful—use it wisely

Glycerin oil makes my hair extremely soft, sometimes too soft. Used alone, it can weigh hair down and leave it looking fluffy instead of defined.

How I use it:

• Mix a small amount with lighter oils

• Or dilute it with rose water, aloe vera juice, or distilled water

• Best used as a light spritz during colder months when hair needs extra moisture

(Pre-made glycerin-based hair mists work well if you don’t feel like mixing.)

Rule #3: Amla oil replaces protein—for that wash day

Amla oil is usually a blend of three oils and leaves hair feeling strong and healthy. If you use it as a pre-poo, you can skip a protein treatment that day.

Two things to know:

• It can slightly darken hair over time

• If you already use extra virgin coconut oil, you don’t really need amla oil

Rule #4: Always test a new oil by itself

Before mixing a new oil into your favorite blend, use it alone first. That’s the only way to know:

• What it actually does for your hair

• Whether your hair even likes it

Your hair will tell you quickly. Listen.

Rule #5: Coconut oil + protein = pick one

If you pre-poo with extra virgin coconut oil, skip protein treatments that day—especially if your hair is protein-sensitive.

If coconut oil ever makes your hair feel crunchy:

• It’s likely solidifying in cold weather

• Warm it slightly before use

• Use less—a little goes a long way

Unrefined, cold-pressed coconut oil works best here.

Rule #6: Never use glycerin oil for hot oil treatments

Glycerin and heat do not get along. As a humectant, glycerin pulls moisture from the air—or from your hair if the conditions aren’t right.

Bottom line:

• No glycerin for hot oil treatments

• Save it for cool or dry seasons, used lightly

Rule #7: Jojoba oil and olive oil do the same job

Both oils:

• Soften hair

• Improve elasticity

• Help reduce breakage

If you already use extra virgin olive oil, you don’t need jojoba oil too. Choose one and keep it moving.

Rule #8: Coconut oil mimics protein

Extra virgin coconut oil bonds easily to the hair shaft, which is why it works so well for many hair types.

It’s great for:

• Pre-poo treatments

• Hot oil treatments

• Strengthening weak or fragile hair

This is one oil worth buying in its purest form.

Rule #9: Jamaican Black Castor Oil supports growth

This is the only oil that actually helps my hair grow. The rest help with moisture and length retention—but Jamaican Black Castor Oil does more.

Benefits:

• Supports scalp health

• Helps hair grow thicker

• Retains moisture without stiffness

Look for authentic Jamaican Black Castor Oil with minimal ingredients.
