Greasy hair causes and remedies
Why is it greasy

Also it can affect anyone but some people are more prone to this condition than others. We will explore the causes and risk factors shortly after understanding the major types.


It can can be grouped in two major categories as follows:

Greasy all over (hair and scalp)

This is when you are experiencing it becomes oily from the root to the tips. In other words, the whole of it is greasy.

Greasy on roots

This is the most common type. It is also known as greasy scalp and dry hair. Usually persons with it will have oily hair at the base or roots.


This condition can be due to numerous reasons. Some causes may involve our lifestyle habits, these can be easily avoided though there are also those causes that one cannot avoid. Above all, the main cause of cause is the overproduction of sebum. The factor influencing over production of sebum will vary for different people.

If you clearly understand the primary cause, then you find very fast and easy solutions for the same. Here are the causes you never imagined:

Seborrheic dermatitis

This is a common known skin condition affecting many people. It may start in infancy as cradle cap. It presents as yellowish, flaking, itching, skin or reddish patches. It usually occur on the scalp, face, neck among other body parts having hair follicles and sebaceous glands.

It is believed that seborrheic dermatitis is due to combination of overproduction of sebum and irritation from yeast malassezia leading to fatty hair and scalp. “Causes for Oily Scalp or excess sebum (the natural oil produced by your scalp) can include genes, hormonal imbalances, humidity, your diet, or even a disease known as seborrheic dermatitis.” [].

From this sentiment, we wish to make it clear that anything causing oily scalp can also hair and therefore seborrheic dermatitis is to blame for this problem.

Hormonal imbalance

For a critical outlook of overproduction of sebum, a natural skin oil, hormonal imbalances can play a greater role. There is this hormonal called androgen. It controls the production of sebum, therefore any imbalance in the level of this hormone can lead to overproduction of sebum and hence this problem sets in when it occurs in the scalp.

Such hormonal imbalance are more prevalent in puberty or in teenagers more so the boys since they are the ones associated with the hormone androgen. Though oily scalp tend to affect men than women, it can also be adverse during pregnancy and menopause and also linked to thyroid problems.

According to medical experts, men are much more vulnerable to extreme effects this greasiness on hair, scalp as well as dandruff.

Weather Changes

The environment will also actually define a lot to do with greasy scalp. It is believed that the more humidity, the more the oil your scalp will produce and then leading to oily hair.

Summer weather also can also bring another problem altogether.  The rise in temperatures during summer time will lead to increased sweating that in the mix with scalp oil and lead to very greasy hair. Some of the protective wear on the head during summer weathers may also aggravate it.

Dry scalp

All the factors leading dry scalp can also be blamed for greasy hair. When the scalp skin becomes dry, the sebaceous glands will react by producing more sebum but it can be unfortunately when the sebum are produced in excess as your skin tries to compensate.

Factors leading to dry scalp include hot and humid weather, raised temperatures, frequent shampooing, certain medications and some medical conditions (such as psoriasis and seborrheic dermatitis) among others.

Wrong hair care products (and over application)

Utilization of wrong care products or using wrong application methods can also lead to glossy strands in the scalp. Picking wrong shampoo for instance may wreak havoc with your scalp’s sebum secretion. Always make sure you pick shampoos corresponding to your hair type or skin problem. Be aware not to choose styling products not suitable. “Look for lightweight formulas and avoid ones that promise ‘shine’ and ‘moisture’ which would be better suited to dry or dull hair types,” advises

Another issue with these products that can lead to oily hair is their over-use for instance shampoos. Remember over application of shampoo can lead to build-ups on the scalp. This is when over washing lead to counter balance of glossy strands leading to even more oil production

“Using too many haircare products leads to a buildup of the yucky chemicals in these products (which do not wash away) thus leading to greasy hair.” []

Stress and depression

Stress and depression are the beginning of many conditions especially skin conditions and also scalp problems i.e. including this one.

Stress usually affect the functionality of hormones and make your scalp more greasy. It may trigger the surge in the level of some hormone which make the oil glands to be over active and increasing the amount of oil your skin produces. Talk to your doctor on how to limit stress levels and leave a stress-less life.

Touching it too much

Remember to watch out on how often youit. Your hands too produce oil and when you touch your hair too often, you may be smearing it some oil strains. Alternatively, your hands may have come into contact with oily parts of the body such as nose, so when you touch it using the same hand, then you will be transferring oil from the oily area to it. So once you are done with styling it, you should leave it alone!

Poor diet

“A lot of conditions including oily hair are because your diet is not right and something in your diet is causing the sebaceous glands to produce more oil than it should,” says In efforts to avoid greasy scalp, there are certain ingredients you will need to include in your diet and at the same time, there are those ones you limit in your diet as well. F

or a proper diet, the following foods should be included in your diet-foods rich in vitamin B and E and zinc supplement. Many people also think that just because one is suffering from oily hair, he/she should avoid fats completely. No, this is not true.

Remember oily hair also needs some fats too. It is only saturated fats and trans fats that are harmful for the skin and the whole body. Therefore allow good fats but avoid harmful fats in your diet.


You must be very careful with your conditioner, it too can cause this problem. You should bear in mind that using too heavy conditioner for your hair type can weigh it down. Improper washing after conditioning may also lead to the same problem, greasy scalp. You also need to avoid placing your conditioner on all the hair, just dwell on the ends to avoid causing oily roots as well as dull lengths.

Excessive brushing/combing

If you are brushing it  too often, then this can also lead to it being oily. Brushing or combing too much can stimulate oil production leading to glossy hair or oily scalp. Avoid obsessive brushing habit if possible. Just brush wisely as recommended, not too often.

It also important to use clean brushes and combs since all these tools can harbor nasty products on the scalp and hence clogging the scalp hence contributing to oily hair and scalp.

Your hair type

The type of hair you are having can also determine your vulnerability towards this problem. If you have fine hair, then you must understand that you will be prone being oily or greasy. It looks greasier than coarse hair since it has is less surface. Going for best shampoo for fine hair that is oily can be of greater help.

Thick or coily hair will also be greasier at the roots. Remember the curls will prevent or slow the sebum from moving along its shaft and hence it will be oily at its root and your scalp will also be oily.

Persons with thicker hair also have got many follicles and it is true that the more the follicles the more the sebaceous glands and more glands equals to more oil and hence it will be greasy.

Having an oily skin

Those persons with natural oily skin are also prone to this menace. It is believed that if a person has a naturally oily skin, he/she is vulnerable to this conditiion since the body natural system will produce excessive sebum. In such cases, mild trigger can lead to serious greasiness. If you suspect you are having oily skin, then you should visit your dermatologist for more advice on how manage the oily disorder.

Genetic predispositions

This problem can also be a genetic cause. It is believed that this issue can be due to genetic causes. This means that when your relative or parent had a greasy hair then you are also likely to experience the same. Actually, this is the reason why fatty scalp runs in many families.

Not regularly and consistently cleansing it

You are also at higher risk of developing greasy hair if you don’t wash or cleanse it regularly. Imagine what can happen if you cleanse or wash it consistently and yet you are influenced with environmental factors such as smoke, smog or too much makeups. If this problem is due to inconsistent cleansing or washing is temporary, it will vanish as soon as you will change you hygiene habits.

Remember you are also even likely to experience some greasiness after washing if all other factors are not contained!
