From onion juice hacks to trimming your ends every full moon, the internet is full of promises about miracle hair growth. But how much of it is actually true?
If you’re trying to grow longer, thicker, healthier hair, here’s what science says – and the myths you can finally stop believing.
Myth 1: Cutting Your Hair Makes It Grow Faster
Let’s clear this up first: trimming your hair does not affect how fast it grows.
Hair growth happens at the scalp, inside the follicle. Cutting the ends has zero impact on follicle activity. However, trims do prevent split ends from travelling up the shaft and causing breakage – which makes hair appear fuller and healthier.
The truth: Regular trims help retain length, but they don’t speed up growth.
Myth 2: Brushing 100 Strokes a Day Stimulates Growth
This old-school beauty advice refuses to die.
While gentle scalp stimulation can increase blood flow temporarily, excessive brushing actually causes mechanical damage and breakage – especially on fine or colour-treated hair.
The truth: Brush to detangle, not to “stimulate growth.” A clean scalp and good circulation matter, but over-brushing won’t turn Rapunzel overnight.
Myth 3: Hair Grows Faster in Summer Because of Sunshine
You might notice slightly faster growth in warmer months. That’s not because your hair “loves the sun,” but because:
- Increased circulation in warmer weather
- Slight hormonal shifts
- Improved vitamin D levels
However, UV damage can weaken hair protein and fade colour.
The truth: Growth changes are subtle and seasonal – but sun damage is very real. Protect your scalp just like your skin.
Myth 4: Oiling Your Hair Makes It Grow
Hair oils are brilliant for shine, smoothing and protecting the shaft – but they don’t magically switch on growth at the root.
Some oils (like rosemary oil in clinical studies) may support scalp health when used consistently, but pouring coconut oil on your ends won’t affect follicle biology.
The truth: Healthy scalp = better growth environment. Oil is supportive, not transformative.
Myth 5: Expensive Products = Faster Growth
Price doesn’t determine follicle performance.
Hair growth is largely influenced by:
- Genetics
- Hormones
- Nutrition
- Stress levels
- Scalp health
Topical products can improve the condition of the hair you have and reduce breakage — but they can’t override biology.
The truth: Focus on evidence-based ingredients, not luxury packaging.
Myth 6: Wearing Wigs or Extensions Stops Your Hair Growing
This one depends entirely on how they’re worn.
Poorly installed extensions or tight styles can cause traction alopecia (hair loss caused by tension). However, high-quality wigs worn correctly can actually protect natural hair by reducing heat styling and environmental damage.
If you’re experimenting with protective styles or want instant length while growing your own hair, investing in quality matters. For example, you can get your dream wig now with modern lace options designed for a more natural-looking finish and reduced scalp tension when properly fitted.
The truth: Tension causes damage – not wigs themselves.
What Actually Supports Hair Growth
If you’re serious about growing healthier hair, focus on what’s proven:
1. Prioritise Scalp Health
Think of your scalp like soil. Buildup, inflammation and imbalance can disrupt the growth cycle.
- Exfoliate gently if needed
- Avoid heavy product congestion
- Treat dandruff or irritation early
2. Eat for Your Follicles
Hair is non-essential tissue – meaning your body prioritises vital organs first. If you’re low in iron, protein, zinc or B vitamins, hair may thin. For those looking to learn more about nutritional support, it may also be useful to review different supplement options for healthier hair. If you’re noticing sudden shedding, it’s worth checking iron levels with your GP or speaking to a specialist for hair loss who can help identify the underlying cause.

3. Manage Stress
Chronic stress can push hair into the shedding (telogen) phase. This often shows up 2–3 months after a stressful event.
4. Be Gentle
Heat damage, tight styles and over-bleaching cause breakage — which slows visible length retention.
5. Be Patient
Hair grows on average about 1–1.5cm per month. There’s no safe shortcut beyond supporting the growth cycle and preventing breakage.
The Bottom Line
Most viral hair growth “hacks” target the hair shaft — not the follicle where growth actually happens.
If you want longer, stronger hair:
- Protect what you have
- Optimise scalp health
- Nourish your body
- Avoid tension and over-processing
- And give it time
Healthy hair growth isn’t about magic products — it’s about biology, consistency and realistic expectations.
