Dandruff is a harmless dry, white flakes of skin that you brush off your collar or shoulders. However, it can be humiliating and itchy. Dandruff isn’t caused by your hair or how frequently you wash it. Instead, it’s all about your scalp’s skin.
The issue is that skin cells grow and die too quickly. It’s not clear why this happens. Malassezia, a common fungus, may play a role in dandruff. Most healthy adults have this fungus on their scalps, which causes no problems. One theory is that a person with dandruff’s immune system overreacts to the fungus.
When you’re stressed or sick, your dandruff can get worse. Dandruff can be triggered or worsened by cold, dry winters.
Seborrheic dermatitis, also known as seborrhea, is a common cause. Seborrheic dermatitis can occur in other parts of the body, including the ears, the centre of the face, and the centre of the chest, in people who have dandruff.
The following are examples of dandruff signs and symptoms:
On your scalp, hair, brows, beard or moustache, and shoulders you will notice skin flaking.
Itchy scalp is a common complaint.
Cradle cap is characterised by a scaly, crusty scalp in infants.
When you’re stressed, the signs and symptoms may be more severe, and they tend to flare up during the cold and dry seasons.
Dandruff can be caused by a variety of factors, including:
Skin that is irritated and oily.
Skin that is parched.
Malassezia is a yeast-like fungus that lives on the scalps of most adults and feeds on the oils produced by the scalp.
Intolerance to certain hair care products (contact dermatitis).
Other skin conditions, such as psoriasis and eczema, are also present in children.
Factors that increase risk
Dandruff can affect almost anyone, but certain factors can make you more susceptible to getting it:
Dandruff typically begins in adolescence or early adulthood and persists into middle age. That does not rule out the possibility of dandruff in older adults. Some people will have this problem for the rest of their lives.
Being male is a privilege.
Dandruff is more common in males than in females, and it can be embarrassing.
Certain illnesses are listed below.
In addition, Parkinson’s disease and other diseases that affect the nervous system appear to increase the likelihood of developing dandruff. Having HIV or a weakened immune system also increases the risk of contracting the disease.
In some cases, seeing a doctor may be necessary if the dandruff and itching are severe and persistent, or if the symptoms worsen. Depending on the findings, they may determine that there is an underlying problem that will respond to specific treatment.
Various over-the-counter products can help manage flaking and itchiness associated with mild dandruff that does not have a specific cause.
In order to properly prepare the scalp for the application of an anti-dandruff shampoo, individuals should carefully try to remove as many scaly or crusty patches as possible. The shampoo will be more effective as a result of this.
Gently brush or comb out any loose scales or flakes with a comb or hairbrush, and then shampoo with a medicated shampoo. Care should be taken not to remove patches or plaques too aggressively, as this may aggravate the condition.
