Most people are putting oil on their hair and wondering why it still isn’t growing.
Not because the oil is “bad” — but because nobody ever taught them what a growth serum is actually supposed to do.
Your hair is not the starting point. Your scalp is.
And if the scalp — the soil — isn’t healthy, no serum in the world is going to magically fix it.
Natural Hair Growth Serum: What to Look For and What to Avoid
I get asked this almost weekly — in clinic, in my inbox, and when I was writing for Black Beauty & Hair Magazine:
“What’s the best natural hair growth serum?”
The honest answer?
It depends on whether the product understands hair… or just coats it.
After 18 years of formulating for afro and curly hair, I can tell you this: most products on the market are designed to look like they’re working, not to actually support growth.
So let’s break it down properly.
First — what a growth serum is actually meant to do
A real growth serum doesn’t “grow hair”.
It creates the conditions for your hair to grow properly.
Think of it like this:
- Your scalp is the soil
- Your hair is the plant
- A serum is the nutrient system
If your soil is dry, inflamed, clogged, or undernourished, the plant struggles — no matter how much oil you pour on top.
So a good serum should:
- Support scalp health
- Improve the environment around the follicle
- Deliver nutrients where they’re actually needed
- Help reduce breakage so length is retained
Not just sit on the surface and give you shine for 20 minutes.
They shop based on texture and smell.
Not function.
I’ve seen serums marketed as “growth oils” that are essentially:
- 90% mineral oil
- Synthetic fragrance
- A drop of something botanical for marketing
That’s not nourishment. That’s coating.
And coating is one of the biggest reasons I see slow growth in clinic.
Because when the scalp is coated, it can’t breathe properly. It can’t regulate itself. And over time, that affects the follicle.
1. Ingredients that support the follicle, not just the strand
The science is simple.
Hair is made of keratin. Keratin relies on certain nutrients — especially sulphur-containing compounds and amino acids.
So when I’m assessing a serum, I’m asking:
- Does this actually support the building blocks of hair?
- Or is it just making the hair feel soft temporarily?
Ingredients like sulphur, certain herbal extracts, and nutrient-dense oils can help support stronger strands from the root.
Not all oils behave the same way.
Some penetrate. Some coat. Some do both.
Heavy, non-absorbing oils can create a barrier that traps dryness underneath — which is why some people say:
“My hair feels oily… but still dry.”
That’s not hydration. That’s blockage.
A well-formulated serum uses oils that:
- Absorb into the scalp
- Deliver nutrients
- Support moisture balance
Not suffocate the follicle.
3. A formulation that respects the scalp as a living system
Your scalp isn’t a surface. It’s an ecosystem.
It has:
- Microflora
- Natural oil production
- A pH balance
Disrupt that, and growth slows.
In my trichology training, one of the first things we look at is scalp condition before anything else — because it dictates everything that follows.
A good serum should:
- Calm irritation
- Support balance
- Avoid harsh or disruptive ingredients
This is the part nobody talks about.
A product can be brilliant — but if it’s difficult to use consistently, it won’t work.
Hair growth is not about intensity. It’s about consistency.
Just like watering a plant.
You don’t drench it once and expect results. You nourish it regularly.
So your serum should be:
- Easy to apply
- Suitable for regular use
- Compatible with your routine
❌ Mineral oil-heavy formulas
These coat the scalp but don’t nourish it.
Over time, they can contribute to build-up and imbalance.
If a serum smells overpowering, it’s often doing more for your nose than your scalp.
Fragrance can irritate — especially for sensitive scalps.
❌ “Miracle growth” claims
Anything promising overnight growth, guaranteed inches, or instant thickening…
Be cautious.
Hair growth is biological. It follows cycles. No product overrides that.
What a good product does is support the process.
If a serum talks only about shine, smoothness, or styling — it’s not a growth serum.
It’s a finishing product.
This is exactly why I formulated it the way I did.
👉 Grow It Long Hydration Serum
Not as a “quick fix”.
But as a system that supports the scalp properly.
The sulphur component supports keratin structure.
The botanical oils are chosen for how they interact with the scalp — not just how they feel on the hair.
And most importantly, it’s designed to be used consistently without overwhelming the scalp.
Because after 18 years, I’ve learned this:
It’s not the most expensive product that works.
It’s the one that works with your biology.
A quick word about dry scalp and slow growth
I get this question constantly:
“My scalp is dry — could that be affecting my growth?”
Yes. More than you think.
Dry soil doesn’t grow healthy plants.
When the scalp lacks moisture and balance:
- Follicles become less efficient
- Breakage increases
- Growth appears slower (even if it isn’t)
That’s why hydration is not optional.
It’s foundational.
Let’s be honest for a second.
Healthy hair growth doesn’t look like:
- Inches overnight
- Dramatic changes in a week
It looks like:
- Less breakage
- Stronger strands
- Better moisture retention
- Gradual, consistent length over time
That’s how you know the conditions are improving.
And yes — I’ve tested this in real life
Not just in a lab.
When Heavenberry was born, she had six allergies. I couldn’t trust anything on the market.
So I started formulating from scratch.
Everything we used followed one principle:
Support the scalp. Feed the system. Stay consistent.
She’s now 20, with waist-length natural hair.
Not because of one miracle product.
Because the environment was right — from day one.
The truth most brands won’t tell you
Hair growth is not complicated.
But it is specific.
Your hair will grow if:
- The scalp is healthy
- The follicle is supported
- Breakage is minimised
- You stay consistent
That’s it.
Everything else is marketing.
If you take one thing from this
Stop chasing products that promise growth.
Start choosing products that support your scalp.
Because your hair is a plant.
Give it the right soil, the right nourishment, and the right consistency…
…and it will grow.
It always does.
