An itchy scalp can be the result of a variety of different conditions, but is most likely due to dry and flaky skin on the top of your head. Invariably an itchy scalp will also result in your itching your head and then creating flakes of dry dead skin (initially if dry skin was the cause of the itching in the first place). This then can be both embarrassing and uncomfortable, making it something that is important to treat early on. Bellow are some causes of an itchy scalp.
Dry Skin: Dry skin is a very common cause of itching on the scalp, and one that is likely to result in dandruff as well as discomfort. There are many possible causes for a dry scalp, but one of the most likely is that it is the result of a deficiency of oils in the diet. Many fad diets that recommend completely avoiding fats will miss out the essential fatty acids that the body uses to maintain itself. At the same time your body needs all of the amino acids (proteins) in order to make necessary repairs to muscle and skin tissue, as well as vitamins and minerals which are also integral to maintenance of the body in general. As such if you are experiencing dry and flaky skin on your diet currently consists of junk food or minimal food groups, then you are likely to be experiencing a deficiency in your diet leading to your skin flaking. Either repair your diet or begin adding supplements: a multivitamin, a protein shake, omega 3 oil and tribulus terrestris. These supplements between them if you can afford them will fix your skin as well as your hair, bones, tendons, musculature and general health and appearance.
Alternatively another cause of dry skin could be the use of strong shampoos which can dry out the skin and scalp. Try using gentler shampoos for a while and wash your hair less often – a bit of natural grease is actually good for it.
Seborrhoea: Seborrhoea is one of the most common causes of an itchy scalp and is caused by a hypersensitivity to skin yeast (which exists on everyone’s scalps). In its more severe form it is known as seborrhoeic dermatitis and can often spread to the ears, eyebrows, nose and chest and might also cause yellow crusting around the hairline. This is most common in young adult males. Treatment usually involves the use of an anti-fungal shampoo with ketoconazole which will reduce flaking and yeast. Seborrhoea can also be the result of a lack of essential fatty acids, so the above supplement ‘stack’ along with evening primrose oil can also be effective as can moisturising and matiffying creams to reduce the angry appearance.
Nits/Hair Lice: Nits and head lice are a form of parasite that live on the scalp and have been described as ‘mechanised dandruff’. These creatures use by sucking blood from the scalp and spread by crossing from head to head when scalps come into contact with each other. If a scalp becomes infested with head lice it will usually result in around 10-20 adult head lice living in the hair and hundreds of eggs. Up to 5,000 lice can hatch within three months. The best treatment for any kind of scalp infestation is to use a wet comb with a slippery conditioner. ‘Nit combs’ will use far finer teeth in order to catch eggs and nits. Specialised insecticide shampoos and natural repellents and remedies (such as neem seed or tea trea oils) can also be used to suffocate lice. Be sure to comb for lice several times after the infestation is seemingly gone to remove any left over eggs and lice that might be hiding.
Burn: If your itchy scalp is short term then it might well have become burnt. The scalp is a very sensitive area as the skin is normally hidden beneath the hair, as such it can burn very easily and this can be caused by either a hot shower or too much exposure to the sun. Ask someone to check your scalp for redness then try not to rub or itch in the meantime.
