How to Grow Your Hair Faster: What Actually Works (and What’s a Myth)
The honest truth: you cannot dramatically speed up how fast your hair grows from the root. It grows about half an inch, just over a centimetre, a month, and that pace is mostly set by your genetics, age, and health. What you can do is grow longer, healthier hair by protecting it from breakage, keeping your scalp healthy, eating well, and treating any real hair loss. Most “grow your hair fast” hacks are myths. Here is what genuinely helps.
If you have ever searched how to grow your hair faster, you have been buried in rice water rinses, castor oil, gummies, and “cut it to grow it” advice. Most of it is myth, and some of it actively damages your hair. Here is the honest, dermatologist-backed version: what really works, what is a waste of time and money, and the one thing that matters more than speed.
First, how fast does hair actually grow?
On average, scalp hair grows about half an inch a month, a little over a centimetre, which is roughly six inches a year. That rate is largely fixed by your genetics, age, and overall health, and no shampoo, oil, or gummy can meaningfully override it.
Understanding that one fact saves you a lot of money, because it means the real goal is not “faster growth.” It is growing healthy hair and actually keeping it.
The thing that matters more than speed: keeping your length
Here is what almost nobody tells you. If your hair never seems to get longer, the problem is usually not slow growth. It is breakage. Your hair is growing, but the ends are snapping off almost as fast as it grows, so the length never changes.
That means the single most powerful thing you can do for longer hair is not speeding up the root. It is protecting the length you already have. Reduce breakage, and your hair finally starts to gain length.
What actually works
- Fix nutritional deficiencies. Low iron and other deficiencies can disrupt the growth cycle and increase shedding. If your hair is shedding more than usual, get a blood test for iron and vitamin D. This is one of the few things that reliably helps.
- Eat enough protein. Your hair is made of protein, so a balanced diet with enough of it gives your hair what it needs.
- Protect your hair from breakage. Go easy on heat, tight styles, and rough brushing, especially when your hair is wet. A gentle routine is how the length you grow actually stays.
- Look after your scalp. Healthy hair grows from a healthy scalp, so clear any buildup and keep it in good condition.
- Manage stress. Significant stress can push hair into a shedding phase. It usually recovers, but keeping stress in check helps.
- Use treatments with real evidence for hair loss. If you have genuine thinning, minoxidil is the topical with the most proof behind it. Rosemary oil is one of the better-studied natural options, though it works slowly.
What does not work: the myths
- “Cutting your hair makes it grow faster.” It does not. Growth happens at the root, below your skin, so trimming the ends cannot change the rate. Trims are still worth it, because removing split ends prevents breakage and helps your hair keep its length. But that is retention, not speed.
- Brushing 100 strokes a day. An old myth that does more harm than good. Over-brushing just causes breakage.
- Biotin and most “hair growth” gummies. Unless you have a genuine deficiency, supplements do very little for hair growth.
- Rice water and miracle oils. Hugely popular online, but the evidence is thin, and none of them can override your genetic growth rate.
A realistic routine for longer, healthier hair
Pull it together into something you can actually do:
- Eat a balanced, protein-rich diet, and get bloodwork if you are shedding.
- Be gentle: less heat, looser styles, and a soft touch when your hair is wet.
- Keep your scalp clean and healthy.
- Trim split ends regularly to protect your length.
- If you have real hair loss, see a professional and consider a proven treatment.
Do these consistently and your hair will grow as fast as it genetically can, and this time it will actually keep the length.
The bottom line
You cannot make your hair grow faster than your genes allow, and anyone selling you a shortcut is usually selling a myth. But you can absolutely grow longer, healthier hair by protecting it from breakage, feeding it well, caring for your scalp, and treating any real loss. Focus on those, ignore the hacks, and be patient. Healthy hair is a long game.

Frequently asked questions
How can I make my hair grow faster naturally? You cannot speed up the growth rate itself, but you can support healthy growth by eating well, fixing any deficiencies, managing stress, and protecting your hair from breakage.
Does cutting your hair make it grow faster? No. Growth happens at the root, so cutting the ends does not affect it. Trims help by preventing split ends and breakage, which lets your hair keep the length it grows.
How long does it take to grow long hair? At about half an inch a month, expect roughly six inches a year, though it varies with genetics and health. Patience and preventing breakage matter far more than any product.
What is the best thing for hair growth? For most people, the basics: good nutrition, a healthy scalp, gentle handling, and treating any real deficiency or hair loss. For genuine loss, minoxidil has the strongest evidence.
Do hair growth products actually work? Most do not speed up growth. The main exception is a proven treatment like minoxidil for hair loss. See my honest guide to hair growth supplements for the full breakdown.
