Do Hair Growth Oils Really Work? Here's What the Science Says

If you're on a mission to grow longer, healthier hair, you’ve probably seen hair growth oils all over your social feed. But do they really work, or are they just another beauty trend?

The short answer: yes—but only if the formula is right. A high-quality hair growth oil can deliver real results, especially when it's made with powerful, organic ingredients designed to nourish your scalp and strengthen your strands from the root.

At She’s Thick, our signature blonde-specific hair growth oil is formulated to do just that. Here's why the science is on our side.

1. Scalp Stimulation Fuels Growth

Healthy hair starts with a healthy scalp. Research has shown that rosemary oil is just as effective as minoxidil (the active ingredient in many hair loss products) at stimulating hair growth—without the unwanted side effects like itching or flaking.

A 2015 study published in SKINmed Journal found that participants using rosemary oil over a 6-month period saw a significant increase in hair count compared to those using a placebo. The magic lies in rosemary’s ability to increase blood circulation to the scalp, which delivers more oxygen and nutrients to your hair follicles.

She’s Thick Oil uses organic rosemary extract to maximize this scalp-boosting benefit, making it ideal for blondes struggling with thinning or slow-growing hair.

2. Organic Ingredients Protect Colour and Health

Blonde hair—especially bleached or highlighted—needs extra care. Harsh chemicals can dry out delicate strands and strip colour.

That’s why using organic oils is key. Natural oils like jojoba, argan, and coconut offer intense hydration without the toxic load of synthetic ingredients. Organic oils are free from pesticides and contaminants that can irritate the scalp or weaken the hair shaft.

3. Moisture Prevents Breakage

One of the top reasons your hair isn’t growing? Breakage. Dry, brittle strands split and snap before they have a chance to reach their full length.

Hair growth oils create a protective seal around each strand, locking in moisture and reducing damage from heat, sun, and styling. This is especially crucial for blondes, whose hair is often more porous and prone to dryness.

By keeping your hair hydrated from root to tip, She’s Thick Oil helps reduce breakage—so your hair can finally grow without constantly snapping off.

4. Anti-Inflammatory Properties Soothe the Scalp

An irritated scalp is not a fertile ground for hair growth. Many natural oils have anti-inflammatory and antimicrobial properties that calm redness, itchiness, and scalp conditions like dandruff. A calm, clean scalp environment makes it easier for hair follicles to function optimally.

5. Consistent Use Yields Real Results

Like most good things in life, hair growth oils don’t deliver results overnight. But with consistent use, many users start to see stronger, fuller hair within 6–12 weeks.

By massaging oil into the scalp 2–3 times per week, you’re not only feeding your follicles but also encouraging lymphatic drainage and stress relief—which also play a role in hair loss. Think of your hair care like skincare: consistency is key, and using the right formula matters.

Final Thoughts: Choose Quality, Reap the Benefits

So, do hair growth oils really work? Absolutely—but only when the ingredients are clean, proven, and designed for your hair type.

At She’s Thick, we created the UK’s first blonde-specific growth oil to solve a real pain point: how to grow bleached hair without damaging your colour or scalp. Our formula is packed with organic, science-backed ingredients like rosemary and jojoba—so you can grow thicker, stronger blonde hair, the natural way.
