It’s funny. Hair seems to have a habit of growing quick where it’s not requested. But, as for how to grow hair faster when it comes to our heads, why the glacial pace?
If you’re facing post-trim regret, or your hair splits and flakes as soon as it hits your shoulders, you may be after something that can accelerate the length, fast. The problem is too many brands over-promise on miracle cures, then under-deliver.
We spoke to the country’s leading hair experts to sort what really works, from what doesn’t so you can quit wasting your funds on fads. Plus, we asked them to share the best ways to speed up hair growth once and for all. Spoiler: a lot of it comes down to lifestyle and genetics. Hopefully there’s some tips below that can help you in your long hair journey.
How fast does hair grow?
“On average, hair grows half an inch [around 1.3cm] a month,” says top trichologist and director of communications at Philip Kingsley, Anabel Kingsley. Roughly, that works out at six inches, or 15cm a year, though this may very from person to person.

Are there any miracle treatments that can actually help to grow hair faster?
Beware of “cures” that promise to transform your hair overnight. “There are definitely effective treatments that help to encourage hair growth,” says Kingsley. “However, I would not use the term ‘miracle’. Firstly, bear in mind that any treatment or regime will take time; you can expect to see results at a minimum of six weeks, but more noticeable changes to hair growth occur from the three-month mark of starting something new. This is in part due to the rate of hair growth (i.e. half an inch a month), but it is also due to the individual growth cycles of hairs.”
“Secondly, it is important to realize that there is also no ‘one size fits all’ treatment,” says Kingsley. “It very much depends on your individual internal environment and your lifestyle. For instance, diet, nutritional deficiencies, hormone levels, genetics, general health and stress levels can all influence hair growth. You need to assess what areas need addressing, and act accordingly,” she adds.
In very extreme cases however, top trichologist, Stephanie Sey, notes “the only treatment that is clinically proven to grow hair thicker and faster is minoxidil (commonly known as Regaine), however this medication is only used for those suffering with male or female pattern hair loss.”
What causes hair loss?
“Lifestyle factors like smoking, alcohol and high sugar diets can lead to scalp problems,” says Michael Van Clarke, hairdresser and founder of 3 More Inches. Crash dieting can be detrimental, too. “As hair is a non-essential tissue, it’s the first part of you to be deprived of nutrients when your diet is lacking,” says Kingsley. “Therefore restrictive eating deprives your hair of nutrients and this can cause excessive hair shedding,” she explains.
It might be worth keeping an eye on how tight you tie your ponytail, too – “this can cause traction breakage and may even pull out hairs from their follicles,” warns Kingsley.
How to grow hair faster
In general, the healthier you are, the healthier your hair will be, so rather than simply turning to products, it’s important to keep an eye on your lifestyle. We’ve put together all the factors to consider when encouraging your hair to grow faster so you can identify which may be most relevant for you…
“Hair is made of 97 per cent protein,” says top trichologist, Stephen Carson. “Hair needs sufficient regular amounts of complete protein, vitamins, minerals and water as well as the omega 3 fatty acids found in oily fish, fruit and vegetables,” he adds.
“To ensure your hair is getting the protein it needs to grow, eat at least a palm sized portion of protein at breakfast and lunch. Great examples are fish, eggs, lean meat, low fat cottage cheese, quinoa and pulses,” says Kingsley. “To help ensure that your hair is receiving enough energy for growth (hair cells are the second fastest growing cells the body produces after bone marrow), include a portion of complex carbohydrates with each meal. I.e. brown rice, whole-wheat toast, potatoes with skin-on or oatmeal,” adds Kingsley.
“A poor lifestyle and diet impacts the quality of hair,” as well, says Clarke. So a well-balanced diet is essential for strong, healthy hair.
So, yep, we’re clear: a healthy, well-balanced diet should be the first line of defence. “Vitamin supplements shouldn’t be a substitute for a varied diet,” says Clarke. But if you’re still struggling to get all the nutrients you need, “supplements can help those with an unbalanced regime,” he says.
“Your hair has especially high nutritional requirements which can be difficult to meet through diet alone,” Kingsley acknowledges. “Supplements can be very handy in that they provide your hair with easily accessible nutrients.”
Look for protein, iron, zinc, vitamin B12, vitamin D, Omega 3 and Biotin. “Biotin is especially important to keep the hair healthy because it functions in the synthesis of hair proteins like keratin. Lack of biotin has also been associated with hair breakage and hair loss,” says Clarke. Meanwhile, “B12 is especially important for vegans, as B12 is only found naturally in animal products,” says Kingsley. Philip Kingsley’s Density Healthy Hair Complex (£32) contains a blend of essential vitamins and minerals including biotin. However, before taking supplements, it’s best to consult with a doctor and take a blood test first, advises Carson.
“To enable your body to recover and repair itself, you need quality sleep,” says Carson. “If you have a stressed lifestyle, sleep is important for adrenal recovery.” Effectively, sleep is one of nature’s best medicines – much more effective than what you’ll find in any pharmacy – and it’s free, so it’s important to make it a priority and plan your evenings around ensuring you get enough.
A trim won’t make your hair grow faster, but it can make it look a whole lot better and healthier. “A trim can help to improve and maintain the quality and density of your ends,” explains Kingsley. “Regular trims will help get rid of the old weathered ends of the hair,” agrees Sey. “The ends of the hair are the oldest having gone through repeated washing, combing and styling. If you want to retain the length you are growing then it is essential to trim.”
A trim will mean your hair fits more beautifully, too – just like tailoring in fashion. “As hair grows it changes shape. So regular reshaping as it gets longer is important to keep you happy with your hair all the way through,” says Clarke. As for how often we should trim, Carson recommends every six to eight weeks. It doesn’t need to be much, we’re very fond of hair dusting for keeping the ends in check and looking healthy.
“Hair grows best from a healthy scalp,” says Kingsley, so it’s important to cleanse it regularly. “Shampooing gets rid of the dirt and debris on the scalp, which includes pollution, sweat, and old skin cells,” agrees Sey.
To make the most of it, really massage your shampoo in. “Scalp massage is good for blood circulation which brings oxygen and nutrients to the hair follicle and takes toxins away,” says Clarke.
Finally, it’s a good idea to use an exfoliating scalp mask once a week “to keep your scalp supple and to remove dead skin cells,” says Kingsley. Both exfoliating and cleansing will also help to remove any blockages (like dead skin cells or product build-up) from impeding your hair from growing. You can use a scrub like Ouai’s Scalp & Body Scrub (£36), just be careful to scrub gently so as not to cause breakages, or use a liquid exfoliator like The INKEY List’s Salicylic Acid Exfoliating Scalp Treatment (£11.99).
It’s worth noting that natural doesn’t necessarily mean better, but there are some natural ingredients that are really worth the hype. Camelia oil has been used as a hair and scalp treatment in Asia for generations and has years of proof to back its effectiveness. “It has antioxidant properties, which neutralise free radicals to help keep the skin on your scalp healthy and strong,” explains Peter Bailey, who heads up Unilever’s Research and Development team. Aloe vera can soothe scalps and moisturise strands while balancing sebum, charcoal can absorb excess oils, kelp and olive oil are gentle and nourishing and honey is antibacterial.
And, we couldn’t not mention rosemary hair oil. The natural ingredient has been blowing up on TikTok thanks to its holy grail growth abilities, according to some users. In fact, a 2015 study comparing rosemary oil to minoxidil (a popular hair regrowth treatment) showed that after six months both groups had seen significant increases in hair growth. However, the group that was treated with rosemary oil had more hair growth than the minoxidil group. You can learn more about it here.
And, we also had to shout-out Klorane’s Anti-Pollution Shampoo (£10.50) which contains detoxifying aquatic mint. All are worth looking out for in our haircare. Meanwhile, chemicals like SLS do an impressive job of deep-cleaning our hair, but can create problems elsewhere such as dryness and itchiness on sensitive scalps, so may be one to red-flag if you’re prone to irritation as a sore scalp isn’t the best starting place for healthy hair growth.
“Conditioning masks help to strengthen your hair, reducing breakage – which can improve the thickness of your mid-lengths and ends. If your ends are breaking, your hair simply won’t be able to grow as long as it otherwise could. They also plump your hair shaft with moisture, giving strands the appearance of more body,” says Kingsley. Team GLAMOUR took Olaplex’s No.8 Bond Intense Moisture Mask (£26) for a test-drive and were blown away by the results.
It improves the look and condition, too. “Shampooing lifts the surface cuticle of the hair shaft so conditioner is essential for smoothing this down and protecting the hair shaft,” says Clarke. Using a good conditioner will help you restore moisture and also help give the hair a lovely look and feel – in some cases it may make it more manageable,” adds Sey.
“If you are wedded to your styling tools you definitely need to use heat protectors,” says Carson. “In my opinion today’s powerful hair dryers are set on high temperatures that are too hot,” he adds.
Kingsley agrees, noting that some hair tools can get hot enough to caramelise sugar. In order to reduce the damage, don’t hold your dryer too close to your hair “hold it approximately 30 centimetres away,” says Kingsley. Opt for a medium or low heat setting, and turn your dryer off as soon as your hair is just dry. “Applying heat to already dried hair evaporates precious moisture from within your hair shaft, which can cause brittleness and breakage,” says Kingsley, so try to limit using your straighteners or tools to once a week if possible. “And don’t go over the same areas of hair repeatedly,” warns Kingsley. Even better, we love these air-drying tips for embracing your natural texture.
We know that dying and bleaching can be damaging for our strands, ultimately causing breakage if done irresponsibly or incorrectly. That said, one of the best things about our hair is being able to have fun with it and play with colour. Gorgeous hair colours can do wonders for our confidence – and while, yes, it does cause damage there are steps we can take to mitigate this as much as possible.
Firstly, “go to a salon and have a colour technician look after your hair if you are going to bleach it,” says Carson. “This is a chemical process that should be carried out by a qualified professional.”
Secondly, “take steps to hydrate and strengthen the strands between processing,” says Kingsley. “If your hair is coloured use a shampoo and conditioner specific for this type. It will be formulated to keep the cuticle tight to try and keep the colour pigments locked in the hair,” Carson explains, while Sey recommends regular deep conditioning treatments.
Finally, “leave enough time between your colour appointments (preferably 8 weeks),” says Kingsley. “If you have colour done too soon, it is more likely to overlap and cause damage.”
“Your hair is weakest when wet,” says Carson. “This is because water separates some of the bonds. When the hair is dry, the bonds are reformed,” so it’s important to be gentle when brushing it wet.
Detangle from your ends and use a gentle hair brush. “A brush with rounded, plastic prongs and a vented cushioned base is the most friendly of brushes,” says Kingsley. We love the WetBrush Detangler Brush (£11.99) and the Philip Kinglsey Vented Paddle Brush (£25). Avoid anything with harsh boar bristles since this can remove sections of your outer hair cuticle says Kingsley and avoid brushes with metal prongs. “These have the tendency to get very hot when you heat style and can burn both your scalp and your hair.”
As for hair bands, soft fabric is your best bet. “Hard ties and clips in and out of the hair can lead to breakage,” says Clarke. “Anything that ties the hair should have some give so that if there is any pressure it can flex around the hair shaft.” Hard metal edges can cut into your hair and lead to snapping, so avoid. We love the pure silk hair ties from Silke (£30) which come in a range of pretty colours and the stretchy Invisibobbles (£4.99) which holds hair in place without causing kinks.
