Crown Clinic's hair transplant surgeon Asim Shahmalak often gets asked to list the most common reasons for hair loss. By the time they are 60, 60% of men and around half of women will have experienced some kind of hair loss. The main difference in the sexes is this hair loss is far more likely to be permanent in men. The most effective treatment for hair loss in either sex is a hair transplant  – either an FUE or FUT procedure. 

1 Stress or trauma – temporary hair loss can be triggered by any kind of physical trauma – maybe surgery, a car accident, a severe illness or even a more everyday malady such as flu. This can trigger a condition known as telogen effluvium. Everyone's hair has a life cycle – a growth phase, rest phase and shedding phase. Asim Shahmalak explained: “Physical stress can play havoc with this life cycle – putting more hair in the shedding phase. The good news is that hair loss caused by stress or ill health tends to be temporary so your hair is likely to grow back when you are feeling better.”

2 Pregnancy – this is linked to the stress highlighted above. It is far more likely to become a problem AFTER childbirth, mainly because having a baby is such a huge event for any woman. Asim Shahmalak said: “Once again, the good news is that this type of hair loss is temporary and the hair nearly always grows back as the woman's body normality.”

3 A lack of protein -if you're not eating enough meat and fish, your body may feel it needs to ration the protein it is receiving by shutting down hair growth. You can expect to see symptoms two to three months after your protein intake decreases. Again this is easily remedied by upping your consumption of protein.

4 It's in the genes – by far the most common cause of hair loss in both sexes is a family history of baldness. Dr Shahmalak said: “If you there is a strong baldness gene in your family the chances are you will lose your hair, too. Look at the royals  – there is a powerful baldness gene running right through from the grandfather (Prince Philip), to the father (Prince Charles) to the son (Prince William).”

5 Female hormones – a change in a woman's routine can trigger hair loss – for instance, coming off the pill. The change in the hormonal balance that occurs at menopause may have the same result.

6 Anaemia – This is particularly common in women. Around one in ten women aged 20 to 40 suffers from anaemia at some point in their lives – due to an iron deficiency. Dr Shahmalak said: “This is easily fixable. First you will need to have a blood test to determine the type of anemia you are suffering from. If it is an iron deficiency, there are lots of supplements you can take. Most other strains of anaemia are also treatable.”

7 An underactive thyroid – this is a small gland in the neck which produces the hormones that are critical to metabolism as well as growth and development. Again this is treatable with synthetic thyroid medication. Once your thyroid levels return to normal, so should your hair.

8 An overactive immune system – this is basically autoimmune-related hair loss. It is called alopecia areata and happens when the immune system sees the hair as foreign and targets it by mistake. It can be treated with steroids.

9 Polycystic ovary syndrome – an imbalance in male or female sex hormones. An excess of androgens can lead to ovarian cysts, weight gain, a higher risk of diabetes and changes to the menstrual cycle. These hormone imbalances can be helped with improved diet and regular exercise.

10 Trichotillomania – this is a psychological condition where sufferers pull out their hair. One famous previous sufferer is Sam Fairers who starred in the TV show The Only Way Is Essex. The main treatment is psychological – the patient needs to change behaviour patterns and learn to stop out pulling their hair.

11 Over styling – women, in particular, can permanently damage their hair by over-styling. Naomi Campbell is a good example of this phenomenon – she suffers from traction alopecia, a condition caused by years of tight hairstyles, over-processing of the hair and applying glues.

When the sun comes out, we know that we need to apply sunscreen to protect our skin, but many people forget to pay the same care to protecting their hair. Between the sun, sea and swimming pools, many of our favourite summer activities can significantly damage our hair – so the next time you go out to enjoy the sunshine, find out what you can do to protect it.


Why does sun damage the hair?


Sun damage to the hair is caused by the harmful UVA and UVB rays, which damage the outermost layer of the layer – the cuticle – and weaken the protein structure of the hair, making it dry, brittle and more prone to breaking. Some people find that their hair lightens in the sun, as the rays act in a similar fashion to bleach, stripping the melanin from the hair.


Protecting your hair from the sun


Wearing a hat is an easy way to protect your hair and scalp from the sun, especially if you’re outside when the sun is at its strongest. Hair SPF is also an option, which can usually be bought as a spray to be misted over the hair. Pay extra attention to the scalp – many people forget that the scalp can burn just as easily as the rest of the skin, ending up with an itchy, flaky, burnt scalp. If you do burn your scalp, rinse your hair in cool water and apply aloe vera to the affected areas, and make sure to keep your head covered when going outdoors.

If your hair is looking dry, try a deep conditioning treatment to restore some of the lost moisture to the hair, and avoid wearing your hair in any tight styles that may pull on the scalp. Summer is also a good time to temporarily stop using hairdryers, straighteners and any other hot tools to avoid adding to the sun damage.


Protecting your hair from the sea


Salt water is notorious for drying out the hair. It leaches moisture out of it, making it incredibly brittle and tangled, which can cause significant breakage. Before you go swimming, saturate your hair with clean water to prevent it from absorbing as much salt water, and don’t let it sit in your hair – rinse it thoroughly as soon as you get out of the sea. Deep conditioners and hair masks will also help replenish the moisture.


Protecting your hair in a swimming pool


Just like salt water, chlorinated water is very harsh and drying on the hair, so you can take similar precautions to swim in the sea. You could also try a swimming cap, as this not only prevents the chlorine from damaging your hair, but it will also protect your scalp from sunburn. If you have highlighted or blonde hair, be especially careful when in a swimming pool, as the copper and chlorine in the water have been known to form a film that sticks to the proteins in hair, turning it a green shade. Thankfully, this isn’t permanent, but make sure to enter the pool with wet hair and rinse it as soon as you get out.

However you are spending your summer, if you have any questions or queries about your hair, take a look at our hair advice or give our team a call.

Over the past few months, there have been a significant number of reports in the news of people experiencing hair loss after being diagnosed with COVID-19. As a result, the Centres for Disease Control and Prevention (CDC) has listed hair loss as a possible long-term effect of the illness, along with symptoms such as fatigue, dizziness and joint pain. 

A study published by the medical journal The Lancet reported that 22% of the patients it had observed suffered from some degree of hair loss six months after falling ill, with women being more affected than men. 


Why does COVID-19 cause hair loss? 


Although there are several studies linking coronavirus and hair loss, many of the reports we hear about are anecdotal – at the moment, it’s too soon for scientists to officially establish a link between the two. 

However, the type of hair loss that COVID-19 sufferers are reporting seems to be consistent with telogen effluvium. Telogen effluvium occurs when more hairs than usual suddenly enter the shedding phase of the hair growth cycle at once, causing a more noticeable amount of hair to shed at once. It’s normal to lose up to 150 hairs per day, but if you spot that you’re losing much more than that – such as clumps coming out when you’re brushing or washing your hair – it could be telogen effluvium. 

Due to the length of the hair cycle, telogen effluvium typically occurs two or three months after a period of significant stress, which can include illnesses such as COVID-19. When undergoing stressful situations, the body puts all its resources into maintaining essential functions only – which, unsurprisingly, does not include hair growth. As a result, you end up with hair loss. 

However, several other conditions can cause hair loss – such as thyroid issues or nutritional deficiencies – so if you are concerned, visit your GP, who can rule out other underlying causes with a simple blood test. 


Will my hair grow back after having COVID? 


If the hair loss is the result of telogen effluvium, most people will find that the hair will eventually grow back without the need for treatment. Typically, once the trigger or stressor is removed, the hair will grow back on its own. 

If you notice that the hair loss is persisting, there are a number of medical, cosmetic and hair transplant treatments available to help – Crown Clinic offers a range of options to support those struggling with hair loss, so don’t hesitate to get in touch

When performed by a qualified, experienced hair transplant surgeon, hair transplants are a very safe procedure. Hair restoration is a minimally invasive treatment that allows patients to return home the same day, with the procedure only requiring local anaesthetic. 

However, if you undergo a hair transplant abroad – such as in Turkey – the risk attached is much higher. 


Risks of hair transplants in Turkey 


It’s no secret that undergoing hair transplant surgery in countries such as Turkey is a gamble. Every year, countless patients are reeled in by the low prices and package deals offered by overseas clinics. Many of the clinics boast ‘five-star’ ratings and an active social media presence, duping unsuspecting patients into thinking they are visiting a reputable clinic. Although, when you dig a little deeper, you may discover the reviews are faked and the ‘after’ pictures are heavily edited or taken from other clinics. 

Another trick that patients fall for is believing that a surgeon will be carrying out the procedure, as many of the clinics advertise that a surgeon leads them to convince patients that they are legitimate. Unfortunately, that doesn’t mean a surgeon will be carrying out the hair transplant itself. In fact, many clinics hire under-qualified technicians with little training to keep the costs down, only seeking the supervision of a surgeon if the procedure goes wrong. 

Over the years, Crown Clinic has fixed countless botched hair transplants, mainly from overseas clinics. The most common problems that we see are unnatural-looking hairlines and unsightly scarring as the result of the surgery being carried out by unlicensed practitioners. Other risks are infections, as sanitation is often extremely poor at the clinics and damage to the scalp due to the result of the incorrect tools being used to carry out the surgery. 


Are there any side effects to having a hair transplant? 


If you choose to have a hair transplant in the UK with a reputable surgeon, side effects will be minimal. The hygiene standards will be incredibly high, meaning the risk of infection is negligible, and you will be given clear instructions on how to take care of your scalp after the procedure. Crown Clinic has an excellent aftercare service, offering a day-by-day guide to ensure optimum healing and results.  

Unlike at overseas clinics, where it can be impossible to follow up after the procedure to discuss any concerns related to your hair transplant, Crown Clinic is more than happy to answer any questions you may have during this phase.
