Key takeaways
Your scalp is the foundation of healthy hair growth, which is one reason it’s so important to take care of it. A healthy scalp is free from product buildup, and has strong circulation to maximise the flow of nutrients, oxygen, and energy to your hair follicles. Any conditions like eczema or scalp psoriasis are well-controlled, reducing itchiness and inflammation that can lead to hair breakage.
In addition, research has shown that poor scalp health can increase oxidative stress, which inhibits hair growth even before it starts emerging from the scalp [1-2]. Below, explore all the major ways that scalp health can affect hair growth.
Clinical scalp conditions like eczema, psoriasis, seborrheic dermatitis, and dandruff can all impact your hair. While mild forms don’t usually cause hair loss by themselves, they can make your scalp feel itchy and sore. Scratching your scalp can make your hair break off, leaving it looking thin and scraggly.
The table below shows the common symptoms of each scalp condition, and effective treatments for controlling them [3-5].
The fungus that causes many of these scalp problems is Malassezia. Malassezia overgrowth can also cause oxidative damage, which may lead to premature hair loss [1]. So treating these scalp conditions may also reduce oxidative stress and promote healthy hair growth.
If your scalp circulation is weak or compromised, your hair can suffer. The follicles require plenty of nutrients, oxygen, and energy to produce hair, all of which reach the follicles via the bloodstream.
Blood flow tends to slow as you get older, which is one reason why our hair naturally thins as we age [1]. But there are other causes of poor scalp circulation, including high cholesterol, inflammation, and scalp tension [6].
Even if you’re not affected by specific scalp conditions, poor scalp hygiene can lead to problems with hair growth. Product buildup can clog your hair follicles, impeding growth and causing problems like scalp folliculitis. These small red bumps are unsightly and itchy, and can often be avoided by practising good scalp hygiene.
Studies have also shown that washing your hair more frequently — around 5-6 times a week — can improve hair growth [7]. So if you only wash your hair once or twice a week, increasing hair wash frequency may be a simple way to boost scalp care to improve hair growth.
Many popular hair products contain ingredients that can cause skin irritation, especially if you have a sensitive scalp. The following ingredients are very common in shampoos, serums, and lotions, and have been shown to irritate the scalp when used frequently [8]:
These ingredients are safe, but if they make your scalp feel itchy, you might want to avoid them. Excessive scalp scratching can make your hair break off, causing it to look thin and limp.
Excessive sunlight exposure can have a detrimental effect on hair and scalp health. UV rays have been shown to damage the hair cuticle, leading to breakage and damage [9].
In addition, some research suggests that scalp exposure to UV rays can aggravate androgenetic alopecia (also known as male pattern baldness or female pattern hair loss) [10]. Going out without adequately protecting your scalp from the sun — especially if you’re already starting to lose hair — may lead to accelerated hair loss.
Ready to create a scalp care routine that promotes the strongest possible hair growth? Follow the steps below for a healthier scalp.
Research shows that washing your hair every day (or least 5-6 times a week) can help boost hair growth [7]. Regular hair washes reduce product buildup on your scalp, unclogging your follicles so hair can grow unimpeded.
For extra hair growth benefits, consider using a shampoo containing caffeine or ketoconazole. Caffeine shampoos have been shown to boost hair growth when used consistently over several months [11-12]. Shampoos containing ketoconazole for hair loss help control scalp conditions like seborrheic dermatitis, while also reducing the impact of dihydrotestosterone on your hair follicles [13].
You may wish to use these shampoos alongside medicated shampoos if you need to control specific scalp conditions.
If you have undiagnosed itchiness, plaques, scales, rashes, or inflammation on your scalp, it’s best to seek a professional opinion. Your GP or a qualified private trichologist can diagnose the cause of your scalp problems and recommend specific treatments for your condition.

Optimise scalp circulation using techniques that are proven to help boost blood flow to the scalp. These include:
Combining these treatments will give you the best possible results. Microneedling increases absorption of minoxidil and other scalp serums, potentially increasing their effects [16].
In-clinic treatments like platelet-rich plasma hair therapy and low level laser therapy can also help with cell proliferation in the scalp, which promotes hair growth.
Make sunscreen application part of your daily routine before leaving the house. If you still have good hair coverage, apply sunscreen right up to the hairline and along your parting. If your hair is thinning or you have visible bald spots, make sure these are covered with sunscreen. Use a minimum of SPF 30+ and reapply regularly, according to the product’s instructions.
Wearing a hat is another option if you don’t want the hassle of regular sunscreen application.
Dry, flaky, or irritated scalps can benefit from increased water intake throughout the day. Drinking more water will hydrate your scalp skin, reducing dryness and flaking.
52% of adults in the UK don’t drink the recommended amount of water, which could be impacting your scalp health [17]. The NHS advises drinking 6-8 glasses of fluid a day. Water is best, as it doesn’t affect your teeth and overall health compared with fizzy drinks, juices, tea, and coffee.
Tight hairstyles that tug on the follicles can lead to a type of hair loss known as traction alopecia. Hairstyles like tight braids, ponytails, buns, cornrows, and dreadlocks can all place mechanical stress on the scalp, leading to temporary hair loss. If the hairstyle is left in place long-term or worn repeatedly, hair loss can become permanent.
Traction alopecia is particularly prevalent in women with Afro hair textures, due to the popularity of tension-inducing hairstyles among Black women [18].
If you tend to wear your hair in these styles, make sure to have prolonged breaks between them. Change your style regularly so the follicles have a chance to rest and recover.
If you have a sensitive scalp, look for products that contain effective active ingredients without potential allergens or irritants. This can be a hard balance to strike, especially if you don’t know which ingredients can pose problems.
Here are our top tips for finding effective scalp products for sensitive skin:
Product ingredients are just one potential cause of an itchy scalp. If you’ve tried multiple products and none of them resolve the issue, seek help from your GP or a qualified trichologist or dermatologist.
Consistency is key to good scalp care and healthy hair growth. Once you’ve found the ideal product selection to control scalp irritation and promote hair growth, you’ll need to apply these consistently according to each product’s instructions to achieve and maintain your results.
Good scalp care isn’t the only factor that affects hair density. Genetics and hormones are the main causes of hair loss, so these are the biggest challenges to overcome if you’re serious about tackling hair loss.
Treatments that block dihydrotestosterone (DHT) production are the most effective treatments for androgenetic alopecia. Finasteride is the most popular and prevalent DHT blocker; it can slow hair loss and even stimulate regrowth in responsive patients.
Finasteride and other DHT blocking treatments (such as dutasteride) aren’t generally appropriate for women, as they can interfere with your period and cause problems in pregnancy. But other anti-androgen treatments like spironolactone may be prescribed off-label to women with female pattern hair loss.
Alongside minoxidil, evidence-based essential oils, and over-the-counter hair density serums, there are many prescription and off-label treatments available to tackle hair loss. A qualified trichologist at the Wimpole Clinic can help you create a scalp care and hair growth plan bespoke to you, giving you the best possible chance of great results.
The Wimpole Clinic’s highly qualified trichology team is optimally placed to treat any clinical scalp conditions you have and get your hair growth back on track.

Minoxidil 5% is the best topical treatment to promote hair growth. With decades of evidence to support its use, it’s usually the first-line treatment for anyone experiencing hair loss.
Minoxidil is available over the counter, so you can buy it online and at many high street pharmacies. Minoxidil is generally safe for both men and women to use, though those with sensitive scalps may prefer to use minoxidil foam rather than minoxidil spray, as the foam formulation doesn’t contain propylene glycol.
Women may also prefer to use minoxidil 2%, as it reduces the risk of unwanted facial or body hair growth.
Dandruff isn’t a cause of hair loss by itself, though the accompanying scalp itchiness can lead to hair breakage if you find yourself scratching your head vigorously. If you have a dry scalp and hair loss, it’s important to find a way to control the dryness and stop itching. Possible treatments include:
Drinking more water may help hydrate your scalp if you don’t currently drink enough fluids throughout the day. Aim to drink at least 1.5 litres of water per day to promote scalp health and overall hydration.
Yes. Studies have shown that massaging your scalp for 11-20 minutes per day for at least 5 months may lead to increased hair growth [13].
Combine regular scalp massage with other proven treatments like minoxidil and microneedling to enhance hair growth.
Scalp dryness isn’t the only issue that can affect hair growth. Excessive sebum production or product buildup can make your scalp feel oily and greasy.
In these cases, wash your hair regularly (at least every other day) to remove excess oil and minimise the risk of clogged follicles. Use a clarifying shampoo or a shampoo containing lauryl or laureth sulphates, as these have more intense cleansing agents to eliminate ingrained product buildup and sebum.
