Causes of dandruff of the scalp
Skin rejuvenation is a continuous process. To maintain healthy skin, new cells are formed and old cells are eliminated. When the renewal cycle accelerates, areas of dead skin cells are displaced and then appear on the hair itself - resulting in an undesirable appearance. This excessive peeling has several causes, and therefore several methods of treatment.
There is a common misconception that dandruff is caused by poor personal hygiene . incorrect! Dandruff does not appear as a result of poor hygiene, but it will appear less noticeable after washing the hair, because oils and skin cells will fall out when washing the hair.
Sometimes, dandruff appears as a result of the overgrowth of a yeast-like fungus known as Malassezia. This fungus grows on most people's scalps and feeds on scalp oils, making oily scalps more susceptible to dandruff. Oleic acid, a by-product of the metabolism of these fungi, causes an increase in the generation of skin cells, which leads to the formation of this white crust.
- An oily scalp, itself, may cause dandruff when sebum secreted by the scalp accumulates. Irregular or incorrect hair washing is usually the cause of the accumulation of sebum, which combines with dead cells and dust to form white pieces that in turn cause itching.
- Dandruff may form as a result of dry scalp. Especially during the winter when hair is washed with hot water. Hot water dries out the hair and scalp, making it flaky. These flakes of dandruff caused by dry skin are usually less oily and smaller than those caused by other causes. There is no redness or inflammation.
- Some skin conditions, such as seborrheic dermatitis, increase the growth of yeast on the skin, and also cause dandruff. This causes increased oiliness of the face and scalp, redness, flaking and itching. What distinguishes this condition is that the skin flakes may not only be white, but may also be yellowish in color.
- Another type of fungal infection that causes dandruff is scalp ringworms called tinea capitis. Symptoms of this condition include severe itching on the scalp and in hairless spots where the fungus grows.
- Contact dermatitis is an allergic reaction to certain chemicals used in products. Products such as hair dye, hairspray, gel and mousse sometimes cause this reaction, excessive production of skin cells. In these cases, this excessive production leads to flaking of the scalp skin, which in turn combines with sebum and dust, causing dandruff and itching.
- Some skin diseases, such as psoriasis, also cause an increase in dandruff. Psoriasis causes rough areas of skin that are red, scaly, and have silvery scales.
- Eczema also causes skin redness, flaking, and dryness. In addition, it causes itching, which makes the crust more noticeable when scratched.
- The role of hormonal changes and stress cannot also be ignored, which are two known reasons for stimulating the appearance of dandruff. As well as neurological conditions such as Parkinson's disease, suppression of the autoimmune system, and chronic conditions such as stroke.
Dealing with dandruff
Treating dandruff may require some attempts, which may sometimes be ineffective until the optimal treatment is achieved.
Dandruff may disappear in some mild cases by regularly washing the hair using a gentle cleanser. If the condition does not improve, a special shampoo is used to treat stubborn dandruff. Choosing the right shampoo depends on the factor causing dandruff. It is recommended to seek specialized advice in this regard, as each type of shampoo works in a special way
Shampoos containing zinc pyrithione act as antifungals and antibacterial agents, and they help deal with the fungi that cause dandruff and seborrheic dermatitis. While shampoos containing selenium sulfide hinder the growth of problematic skin cells on the scalp. It slows down the death of skin cells.
It is worth noting that salicylic acid helps scrub the scalp, but it may also cause dryness of the hair scalp, which exacerbates the problem of dandruff.
Tar-based shampoos help deal with psoriasis and seborrheic dermatitis by slowing the rate of cell death and peeling.
There are shampoos that contain ketoconazole, which primarily target fungi. Some people may want to resort to ketoconazole when other shampoos do not work. Since it is a broad-spectrum antifungal.
In addition to shampoos, there are also cortisone-based creams and lotions that aim to reduce inflammation. As for anti-fungal and anti-bacterial lotions, they seek to stop their reproduction.
I cannot ignore home remedies, many of which help protect against dandruff, such as applying curd, lemon, salt, garlic, and apple cider vinegar. Aspirin, baking soda, and mouthwash. Coconut oil, olive oil, tea tree oil, and aloe vera oil.
It must be known that reducing the use of hair styling products such as dyes, gels and mousses has also proven effective. In addition to causing seborrheic dermatitis, it collects on the scalp, causing an increase in sebum on which the fungi that live on the scalp feed.
If the dandruff does not disappear using shampoos and traditional home methods, or if the scalp is red or swollen, then there is a need to visit a dermatologist. The doctor will conduct a comprehensive scalp examination, and if the cause is not clear, he will take a scalp biopsy to determine the root of the problem causing the dandruff.
Stop the problem once and for all
Timely medical intervention is extremely important, especially since some cases such as seborrheic dermatitis may spread to other areas such as the eyebrows, sides of the nose, behind the ears, chest, upper thigh and underarm.
There is also temporary hair loss associated with dandruff as a result of damage to hair follicles with frequent scratching of the scalp.
In addition to the above, dandruff also falls on the face, causing clogged facial pores and increasing the possibility of acne and pimples appearing. The forehead, which is most susceptible to dandruff loss, is the area most affected by these results.
Regardless of the factor causing dandruff, there is nothing that cannot be resolved with professional advice. Ask your doctor and be confident that you will lift the burden of dandruff from your shoulders.
